Publication A Novel Antegrade Approach for Simultaneous Carotid Endarterectomy and Angioplasty of Proximal Lesions in Patients with Tandem Stenosis of Supraaortic Arch Vessels(2017) ;Radak, Djordje (7004442548) ;Tanaskovic, Slobodan (25121572000) ;Sagic, Dragan (35549772400) ;Antonic, Zelimir (23994902200) ;Gajin, Predrag (15055548600) ;Babic, Srdjan (26022897000) ;Neskovic, Mihailo (57194558704) ;Matic, Predrag (25121600300) ;Kovacevic, Vladimir (36093028200) ;Nenezic, Dragoslav (9232882900)Ilijevski, Nenad (57209017323)Background To date, all published studies analyzing simultaneous treatment of carotid and proximal atherosclerotic lesions are describing retrograde approach and several technical variations. In the presented study, for the first time, antegrade approach is described for simultaneous carotid endarterectomy (CEA) and associated brachiocephalic trunk (BCT) or common carotid artery (CCA) angioplasty in the hybrid operating room. Methods From January 2012 till January 2016, antegrade hybrid procedures were performed in 18 patients. All patients were admitted to our institute for elective supraaortic arch multidetector computed tomography angiography when significant simultaneous proximal and distal supraaortic arch lesions were revealed. After surgical exposure of carotid arteries, proximal lesions were crossed by antegrade approach. Prior to stent placement, internal carotid artery (ICA) is clamped at its origin with the guidewire placed in the external carotid artery (ECA). After primary stenting and control arteriography, CCA and ECA are clamped and the ICA clamp moved more distally. An arteriotomy is performed in the CCA, with flushing of possible debris and thrombus before performance of the eversion CEA, once again flushing before completion of the anastomosis. Follow-up ranged from 6 to 36 months with average follow-up of 22.15 ± 11.31 months. Results All procedures went uneventfully. Out of 18 patients, 11 were males and 7 females, mean age 66.6 ± 3.82 years. In 10 patients (55.5%), simultaneous CEA and CCA angioplasty was performed, in 7 patients (38.9%) CEA and BCT angioplasty, and in 1 patient (5.5%) tubular graft interposition between the CCA and the ICA and CCA angioplasty. In 6 patients (33.3%), CCA/BCT balloon angioplasty alone was performed simultaneously with CEA. None of the patient had postoperative transient ischemic attack, stroke, hematoma, dissection, myocardial infarction, or ischemia in the early postoperative period and during the follow-up. There were no lethal outcomes, neither in the early postoperative course nor during the follow-up. Conclusions Antegrade approach for simultaneous treatment of proximal CCA/BCT and distal carotid lesions with temporary ICA clamping is safe and feasible procedure that should be thought of in the future in addition to already described retrograde approach. © 2017 Elsevier Inc. - Some of the metrics are blocked by yourconsent settings
Publication A tailored approach to operative repair of extracranial carotid aneurysms based on anatomic types and kinks(2014) ;Radak, Djordje (7004442548) ;Davidovic, Lazar (7006821504) ;Tanaskovic, Slobodan (25121572000) ;Banzic, Igor (36518108700) ;Matic, Predrag (25121600300) ;Babic, Srdjan (26022897000) ;Kostic, Dusan (7007037165)Isenovic, Esma R. (14040488600)Background To present outcomes following an operative approach of extracranial carotid artery aneurysm (ECAAs) based on anatomic types and associated kinks. Methods This study represents retrospective analysis of anatomic type based approach to operative repair of 84 patients with ECAA from 1994 to 2011, 28 (33.3%) with associated kinking. Patients were followed for neurological ischemic events, hematoma, cranial nerve injury, myocardial infarction, neurological, and overall mortality. The results are presented as early, within 30 days after the surgery, and long term during the follow-up. Results In the early postoperative period, there were no strokes or mortalities, cranial nerve injury rate was 2.4% while 1 patient had myocardial infarction (1.2%). During the follow-up, 4 patients (4.8%) had stroke, out of which 2 patients died (2.3%), while overall mortality was 4.6%. The average 5-year survival rate was 96 ± 3%. Conclusion Excellent outcomes can be obtained with surgical repair of ECAA, which should be tailored to the anatomic types and presence of kinks. © 2014 Elsevier Inc.

Publication Analysis of Serbian Primary Antiphospholipid Syndrome Patients Confirmed a Strong Association between Livedo Reticularis and Arterial Thrombosis: A National Cross-Sectional Cohort Study(2022) ;Djokovic, Aleksandra (42661226500) ;Stojanovich, Ljudmila (55917563000) ;Stanisavljevic, Natasa (36163559700) ;Matic, Predrag (25121600300) ;Colic, Danijela (57909790500) ;Skrijelj, Daniel (57212350434) ;Djokic, Sandra (57409274700)Filipovic, Branka (22934489100)Background Antiphospholipid syndrome (APS) is characterized by antiphospholipid antibodies (aPLs) associated with thrombosis (arterial and/or venous) and/or obstetrical manifestations. However, various manifestations, which are considered to be noncriteria manifestations, are frequently found in APS. Aim The purpose of this study was to evaluate whether noncriteria manifestations may be found more frequently in subjects with thrombotic and/or obstetrical APS ("criteria"manifestations) in a population of patients with primary APS (PAPS). This study presents the results from our national cohort. Patients and Methods This is a cross-sectional study of 360 PAPS patients. Data regarding the presence of thrombocytopenia, livedo reticularis, chorea, and valvulopathy were analyzed. The aPL analysis included the detection of anticardiolipin antibodies (aCLs: immunoglobulin G [IgG]/IgM), anti-β2 glycoprotein I (IgG/IgM), and lupus anticoagulant positivity. Results In our cohort, livedo reticularis was significantly related to arterial thromboses in the same way as valvular manifestations (valvular vegetations and valvular thickening and dysfunction not related to age) (p = 0.0001, p = 0.013, respectively). Age was strongly related to all the noncriteria manifestations analyzed. Thrombocytopenia was significantly related to β2 glycoprotein I IgG and lupus anticoagulant positivity (p = 0.043, p = 0.030, respectively), as well as to double and triple aPL positivity (p = 0.041, p = 0.013 respectively). Moreover, in a multivariate model, livedo reticularis was strongly and independently related to arterial thrombosis in our cohort (odds ratio, 2.010; confidence interval, 1.229-3.288; p = 0.005). Conclusion This cross-sectional analysis of a large cohort of Serbian PAPS patients confirmed a strong relationship between livedo reticularis and arterial thrombosis, suggesting a more cautious approach regarding the presence of noncriteria manifestations, especially livedo reticularis, in APS. © Wolters Kluwer Health, Inc.

Publication Anesthesia for carotid endarterectomy: Where do we stand at present?(2015) ;Unic-Stojanovic, Dragana (55376745500) ;Radak, Djordje (7004442548) ;Gojkovic, Tamara (55191372700) ;Matic, Predrag (25121600300) ;Ranković, Ljiljana (36445048900)Jovic, Miomir (6701307928)Carotid endarterectomy (CEA) is a surgical procedure performed to reduce the incidence of embolic and thrombotic stroke. Although only a preventive procedure, CEA carries the risk of perioperative complications. There is constant searching for an optimal anesthetic technique. There are pros and cons for both anesthetic techniques used: regional (RA) and general anesthesia (GA). A large number of studies have compared RA and GA techniques in CEA surgery patients. The primary outcome was the proportion of patients with stroke, myocardial infarction, or death. However, neither the GALA trial nor the pooled analysis was adequately powered to reliably detect an effect of type of anesthesia on mortality. It may therefore be appropriate to consider other additional parameters (stress response, incidence of postoperative delirium and cognitive impairment, functional recovery, total surgery time, intensive care unit requirement, hospital stay, hospital costs and patients satisfaction) when comparing the outcomes of the two techniques. Although, the debate continues as to whether regional anesthesia or general anesthesia is safer, the choice of anesthetic technique is a complex decision and surgical teams should be able to offer both RA and GA. The individual approach is the ideal choice and should be determined at the discretion of the surgeon, anesthetist and patient depending on the clinical situation and own preferences. © 2015 Signa Vitae.

Publication Brief communication: Vacuum-assisted closure therapy for groin vascular graft infection(2014) ;Matic, Predrag (25121600300) ;Jocic, Dario (25121522300) ;Tanaskovic, Slobodan (25121572000) ;Gajin, Predrag (15055548600) ;Nenezic, Dragoslav (9232882900)Radak, Djordje (7004442548)Vascular graft infection is a serious complication associated with high morbidity and mortality. Because of this, various graft preservation techniques have been increasingly utilized in an attempt to improve outcomes. When this devastating complication occurs several possibilities for treatment are available. The traditional treatment consists of graft excision and extra-anatomic reconstruction. Reconstruction can also be done in situ using homografts or autologous grafts, as well as new synthetic prostheses with antimicrobial properties. A more conservative approach and graft preservation may be indicated in some cases. This paper presents a case of successful graft preservation using a vacuum-assisted closure system. - Some of the metrics are blocked by yourconsent settings
Publication Cardiac manifestations in primary antiphospholipid syndrome and their association to antiphospholipid antibodies’ types and titers—cross-sectional study of Serbian cohort(2022) ;Djokovic, Aleksandra (42661226500) ;Stojanovich, Ljudmila (55917563000) ;Stanisavljevic, Natasa (36163559700) ;Djokic, Sandra (57409274700) ;Filipovic, Branka (22934489100) ;Matic, Predrag (25121600300) ;Milanovic, Milomir (7003857551) ;Apostolovic, Svetlana (13610076800)Saponjski, Jovica (56629875900)Objectives: Antiphospholipid syndrome (APS) is multisystem autoimmune coagulopathy with antiphospholipid antibodies (aPL) in its ground, manifested as a primary disease (PAPS) or in the setting of other conditions, most commonly systemic lupus erythematosus. The objective of this cross-sectional study was to investigate various cardiac manifestations and their possible relation to aPL type and titer in a Serbian cohort of PAPS patients. Methods: A total of 360 PAPS patients were analyzed and aPL analysis included detection of anticardiolipin antibodies (aCL: IgG/IgM), anti-ß2glycoprotein I (ß2GPI: IgG/IgM), and lupus anticoagulant (LA). Cardiac manifestations investigated were valvular lesions (comprehending valvular thickening and dysfunction not related to age and pseudoinfective endocarditis), coronary artery disease (CAD) with specific insight for myocardial infarction (MI), chronic cardiomyopathy (CMP), and acute decompensated heart failure (ADHF) as well as pulmonary hypertension (PH) and intracardiac thrombus presence. Results: The prevalence of cardiac manifestations overall was 19.6%. There was a strong association between age and the majority of cardiac manifestations, as well as standard atherosclerotic risk factors. aCL IgG–positive patients had a higher prevalence of valvular lesions (p = 0.042). LA presence was significantly related to MI (p = 0.031) and PH (p = 0.044). CMP and ADHF were significantly related to higher titers of aCl IgG (p = 0.033, p = 0.025 respectively). Age and smoking were independent risk predictors for MI in PAPS with meaningful risk for LA positivity (OR 2.567 CI 0.671–9.820 p = 0.168). Conclusions: Certain cardiac manifestations in PAPS were related to certain aPL type and/or titer levels, imposing confirmation in prospective studies. Preventive actions, comprehending proper anticoagulant/antithrombotic therapy, and intense action against standard atherosclerotic risk factors are of utmost importance in this group of patients. Key Points• In Serbian patients with primary antiphospholipid syndrome (PAPS), prevalence of non-criteria cardiac manifestations was 19.6% and they were significantly related to certain antiphospholipid antibodies and titers.• Lupus anticoagulant was a meaningful predictor of myocardial infarction, enabling possible risk stratification and proper preventive and therapeutical strategies in this subgroup of PAPS patients.• Patients with high titers of aCL IgG are more prone to acute decompensated heart failure occurence, imposing careful follow-up of these patients• Based on the analysis of the Serbian PAPS cohort, even being non-criterial, cardiology manifestations are significantly present and inclusion of cardiologists in treatment and follow-up of these patients should be implied from the diagnosis establishment. © 2022, International League of Associations for Rheumatology (ILAR). - Some of the metrics are blocked by yourconsent settings
Publication Carotid angioplasty and stenting is safe and effective for treatment of recurrent stenosis after eversion endarterectomy(2014) ;Radak, Djordje (7004442548) ;Tanaskovic, Slobodan (25121572000) ;Sagic, Dragan (35549772400) ;Antonic, Zelimir (23994902200) ;Babic, Srdjan (26022897000) ;Popov, Petar (26023653600) ;Matic, Predrag (25121600300)Rancic, Zoran (6508236457)Objective: This study was conducted to determine the efficiency and long-term durability of percutaneous transluminal angioplasty and carotid artery stenting in carotid restenosis (CR) treatment after eversion endarterectomy, with emphasis on variables that could influence the outcome. Methods: We analyzed 319 patients (220 asymptomatic and 99 symptomatic) who underwent carotid angioplasty from 2002 until 2012 for CR that occurred after eversion endarterectomy. During this period, 7993 eversion endarterectomies were done for significant carotid artery stenosis. Significant CR was detected by ultrasound examination and confirmed by digital subtraction angiography or multidetector computed tomography angiography. After angioplasty (with or without stenting), color duplex ultrasound imaging was done after 1 month, 6 months, 1 year, and annually thereafter. End points encompassed myocardial infarction, stroke, and cardiovascular death (fatal myocardial infarction, fatal cardiac failure, fatal stroke), and also puncture site hematoma and recurrent restenosis. Primary end points were analyzed as early results (≤30 days after the procedure), and secondary end points were long-term results (>30 days). Variables and risk factors influencing the early-term and long-term results were also analyzed. Median follow-up was 49.8 ± 22.8 months (range, 17-121 months). Results: All but one procedure ended with a technical success (99.7%). In the early postoperative period, transient ischemic attack occurred in 2.8% of the patients and stroke in 1.6%, followed by one lethal outcome (0.3%). Stent thrombosis occurred in one patient (0.3%) several hours after the angioplasty, followed by urgent surgery and graft interposition. In the long-term follow-up, there were no transient ischemic attacks or strokes, non-neurologic mortality was 3.13%, and the recurrent restenosis rate was 4.4%. The rate of non-neurologic outcomes during the follow-up was significantly higher in asymptomatic patients than in symptomatic patients (4.54% vs 0%; P =.034). The statically highest rate of transient ischemic attack was verified in patients in whom Precise (Cordis Corporation, New Brunswick, NJ) stents was used (12.2%) and a Spider Fx (Covidien, Dublin, Ireland) cerebral protection device (12.5%) was used. Female gender, coronary artery disease, plaque calcifications, and smoking history were associated with an adverse outcome after angioplasty. Conclusions: Carotid artery stenting is safe and reliable procedure for CR after eversion endarterectomy treatment, with low rate of postprocedural complications. Type of stent and cerebral embolic protection device may influence the rate of postprocedural neurologic ischemic events.

Publication Carotid Restenosis Rate After Stenting for Primary Lesions Versus Restenosis After Endarterectomy With Creation of Risk Index(2023) ;Tanaskovic, Slobodan (25121572000) ;Sagic, Dragan (35549772400) ;Radak, Djordje (7004442548) ;Antonic, Zelimir (23994902200) ;Kovacevic, Vladimir (36093028200) ;Vukovic, Mira (8860387500) ;Aleksic, Nikola (36105795700) ;Radak, Sandra (13103970500) ;Nenezic, Dragoslav (9232882900) ;Cvetkovic, Slobodan (7006158672) ;Isenovic, Esma (14040488600) ;Vucurevic, Goran (6602813880) ;Lozuk, Branko (6505608191) ;Babic, Aleksandar (57340398100) ;Babic, Srdjan (26022897000) ;Matic, Predrag (25121600300) ;Gajin, Predrag (15055548600) ;Unic-Stojanovic, Dragana (55376745500)Ilijevski, Nenad (57209017323)Purpose: Carotid artery stenting (CAS) is an option for carotid restenosis (CR) treatment with favorable outcomes. However, CAS has also emerged as an alternative to carotid endarterectomy (CEA) for the management of patients with primary carotid stenosis. This study aimed to report CR rates after CAS was performed in patients with primary lesions versus restenosis after CEA, to identify predictors of CR, and to report both neurological and overall outcomes. Materials and methods: From January 2000 to September 2018, a total of 782 patients were divided into 2 groups: The CAS (prim) group consisted of 440 patients in whom CAS was performed for primary lesions, and the CAS (res) group consisted of 342 patients with CAS due to restenosis after CEA. Indications for CAS were symptomatic stenosis/restenosis >70% and asymptomatic stenosis/restenosis >85%. A color duplex scan (CDS) of carotid arteries was performed 6 months after CAS, after 1 year, and annually afterward. Follow-up ranged from 12 to 88 months, with a mean follow-up of 34.6±18.0 months. Results: There were no differences in terms of CR rate between the patients in the CAS (prim) and CAS (res) groups (8.7% vs 7.2%, χ2=0.691, p=0.406). The overall CR rate was 7.9%, whereas significant CR (>70%) rate needing re-intervention was 5.6%, but there was no difference between patients in the CAS (prim) and CAS (res) groups (6.4% vs 4.7%, p=0.351). Six independent predictors for CR were smoking, associated previous myocardial infarction and angina pectoris, plaque morphology, spasm after CAS, the use of FilterWire or Spider Fx cerebral protection devices, and time after stenting. A carotid restenosis risk index (CRRI) was created based on these predictors and ranged from –7 (minimal risk) to +10 (maximum risk); patients with a score >–4 were at increased risk for CR. There were no differences in terms of neurological and overall morbidity and mortality between the 2 groups. Conclusions: There was no difference in CR rate after CAS between the patients with primary stenosis and restenosis after CEA. A CRRI score >–4 is a criterion for identifying high-risk patients for post-CAS CR that should be tested in future randomized trials. © The Author(s) 2022. - Some of the metrics are blocked by yourconsent settings
Publication Comparison of sclerotherapy, laser, and radiowave coagulation in treatment of lower extremity telangiectasias(2012) ;Tepavcevic, Brankica (55369566700) ;Matic, Predrag (25121600300)Radak, Djordje (7004442548)Introduction: Telangiectasias represent an esthetic problem. Sclerotherapy, laser and radiowave coagulation are established methods of treatment. The aim of the treatment is a cosmetic improvement in the leg appearance. Aim: To define which method provides best results in lower extremity telangiectasias treatment and also to determine which method is most comfortable for the patient. Materials and methods: Thirty female volunteers, ages 3066 years (mean 49 years), were included in the research, with telangiectasias in the thigh measuring 0,1 to 2 mm in diameter, and skin phototype according to Fitzpatrick IIV. Three rectangular areas 3×5 cm2, were marked on the thigh, with nearly same pattern and appearance of telangiectasias in each field. In each rectangle, only one session of sclerotherapy, laser, and radiowave coagulation were performed, respectively. It is completely documented with the digital camera prior to the therapy and 3 months after the treatment. At the end of the study, three blinded experts graded leg telangiectasias for clearance using obtained digital images. Patients were also required to describe the sense of pain during each procedure as minimal, mild, or strong. Chi-square test was used for statistical data processing. Results: After 3 months period, there was a high statistical significant difference among methods of treatment (χ = 45.492, p<0.01). The most efficient was sclerotherapy. Also there was a high statistical significant difference (χ test=30.549, p<0.01) among levels of pain experienced by patients in the study. Minimal sense of pain was associated with sclerotherapy. Conclusion: Our study revealed that the most efficient method in terms of telangiectasias clearance is sclerotherapy. It also showed that most comfortable method for the patient is sclerotherapy, since it produces minimal pain during the procedure. It can be concluded that sclerotherapy is a successful method in treating lower extremity telangiectasias leaving both, patient and physician content. © 2012 Informa UK, Ltd. - Some of the metrics are blocked by yourconsent settings
Publication Enhancing predictive accuracy of the cardiac risk score in open abdominal aortic surgery: the role of left ventricular wall motion abnormalities(2023) ;Djokic, Ivana (6506878745) ;Milicic, Biljana (6603829143) ;Matic, Predrag (25121600300) ;Ilijevski, Nenad (57209017323) ;Milojevic, Milan (57035137900)Jovic, Miomir (6701307928)Background: Open abdominal aortic surgery carries many potential complications, with cardiac adverse events being the most significant concern. The Vascular Study Group Cardiac Risk Index (VSG-CRI) is a commonly used tool for predicting severe cardiac complications and guiding clinical decision-making. However, despite the potential prognostic significance of left ventricular wall motion abnormalities (LVWMAs) and reduced LV ejection fraction (LVEF) for adverse outcomes, the VSG-CRI model has not accounted for them. Hence, the main objective of this study was to analyze the added value of LV wall motion on the discriminatory power of the modified VSG-CRI in predicting major postoperative cardiac complications. Methods: A prospective study was conducted involving 271 patients who underwent elective abdominal aortic surgery between 2019 and 2021. VSG-CRI scores were calculated, and preoperative transthoracic echocardiography was conducted for all patients. Subsequently, a modified version of the VSG-CRI, accounting for reduced LVEF and LVWMAs, was developed and incorporated into the dataset. The postoperative incidence of the composite endpoint of major adverse cardiac events (MACEs), including myocardial infarction, clinically relevant arrhythmias treated with medicaments or by cardioversion, or congestive heart failure, was assessed at discharge from the index hospitalization, with adjudicators blinded to events. The predictive accuracy of both the original and modified VSG-CRI was assessed using C-Statistics. Results: In total, 61 patients (22.5%) experienced MACEs. Among these patients, a significantly higher proportion had preoperative LVWMAs compared to those without (62.3% vs. 32.9%, p < 0.001). Multivariable regression analysis revealed the VSG-CRI [odds ratio (OR) 1.46, 95% confidence interval (CI) 1.21–1.77; p < 0.001] and LVWMA (OR 2.76; 95% CI 1.46–5.23; p = 0.002) as independent predictors of MACEs. Additionally, the modified VSG-CRI model demonstrated superior predictability compared to the baseline VSG-CRI model, suggesting an improved predictive performance for anticipating MACEs following abdominal aortic surgery [area under the curve (AUC) 0.74; 95% CI 0.68–0.81 vs. AUC 0.70; 95% CI 0.63–0.77; respectively]. Conclusion: The findings of this study suggest that incorporating preoperative echocardiography can enhance the predictive accuracy of the VSG-CRI for predicting MACEs after open abdominal aortic surgery. Before its implementation in clinical settings, external validation is necessary to confirm the generalizability of this newly developed predictive model across different populations. 2023 Djokic, Milicic, Matic, Ilijevski, Milojevic and Jovic. - Some of the metrics are blocked by yourconsent settings

Publication Infrarenal abdominal aorta aneurysm: A rare cause of anterior nutcracker syndrome with associated pelvic congestion(2014) ;Lozuk, Branko (6505608191) ;Tanaskovic, Slobodan (25121572000) ;Radak, Djordje (7004442548) ;Babic, Srdjan (26022897000) ;Kovacevic, Vladimir (36093028200)Matic, Predrag (25121600300)We present a rare case of anterior nutcracker syndrome caused by an abdominal aorta aneurysm (AAA). A 61-year-old woman was admitted to our institution for computed tomography angiography. It revealed an AAA 51 mm in diameter that was lifting off of the left renal vein toward the superior mesenteric artery, causing anterior nutcracker syndrome with consequent left renal vein compression and left ovarian vein congestion. Aneurysm resection was performed, followed by left ovarian vein ligation and left adnexectomy to prevent vein conglomerate rupture. This is the first case that describes anterior nutcracker syndrome caused by AAA, which was successfully treated by aneurysm resection. © 2014 by Elsevier Inc.

The demarcation of acute SCAD from coronary atherothrombosis and the proper therapeutic approach still represents a major clinical challenge. Certain arteriopathies and triggers are related to SCAD, with high variability in their prevalence, and often, the cause remains unknown. The objective of this review is to provide contemporary knowledge of the pathophysiology of SCAD and possible therapeutic solutions. 2023 Djokovic, Krljanac, Matic, Zivic, Djulejic, Marjanovic Haljilji, Popovic, Filipovic and Apostolovic. - Some of the metrics are blocked by yourconsent settings
Publication Primary antiphospholipid syndrome as a cause of impaired left ventricular diastolic function: experience from a Serbian cohort(2023) ;Djokovic, Aleksandra (42661226500) ;Stojanovich, Ljudmila (55917563000) ;Stanisavljevic, Natasa (36163559700) ;Veljic, Ivana (57203875022) ;Todic, Branislava (57209854708) ;Radovanovic, Slavica (24492602300) ;Zivic, Rastko (6701921833) ;Matic, Predrag (25121600300) ;Filipovic, Branka (22934489100) ;Saponjski, Jovica (56629875900) ;Apostolovic, Svetlana (13610076800) ;Zdravkovic, Marija (24924016800) ;Milic, Sandra (58082948600)Shoenfeld, Yehuda (36879964800)Objective Cardiovascular manifestations, encountered in antiphospholipid syndrome, may develop as a consequence of acquired thrombophilia mediated by antiphospholipid antibodies and accelerated atherosclerosis as well. Our study aims to assess the impairment of the left ventricular diastolic performance, as early evidence of myocardial involvement in primary antiphospholipid syndrome (PAPS). Methods We analysed 101 PAPS patients, with the average age of 47.70±13.14y. Anticardiolipin antibodies (aCL IgG/IgM), anti-ß2 glycoprotein-I (anti-ß2GPI IgG/IgM), and lupus anticoagulant (LAC) were determined. Abnormal cut-off values used for left ventricular diastolic dysfunction (LVDD) were septal E ́<7 cm/sec, lateral E ́ <10 cm/sec, average E/E ́ ratio >14, LA volume index (LAVI) >34 mL/m2, and peak tricuspid regurgitation velocity >2.8 m/sec. LVDD was present if more than half parameters were with abnormal values. The results were compared to 90 healthy, age and sex-matched controls. Results LVDD was significantly more prevalent in PAPS patients compared to healthy controls (24.8% vs. 2.2%, p=0.001). In PAPS patients, it was significantly related to age, body mass index, hyperlipidaemia, thromboses and LAC positivity (p=0.0001, p=0.008, p=0.039, p=0.001, p=0.047 respectively). Patients with PAPS had higher LAVI (29.76±6.40 ml/m2 vs. 26.62±7.8 ml/m2, p=0.012), higher isovolumic relaxation time, lower lateral É velocity and lower E/É ratio compared to controls (p=0.0001, p=0.020, p=0.038, respectively). In multivariate analysis, thromboses in PAPS were significant, and independent predictors of LVDD. Conclusion Thrombotic PAPS patients are at higher risk of LVDD development. Strong action against standard atherosclerotic risk factors and adequate therapy regimes seems to be crucial to preserve good diastolic performance of the left ventricle in PAPS. © Copyright CliniCal and ExpErimEntal rhEumatology 2023. - Some of the metrics are blocked by yourconsent settings

As we know, APS is also characterised by accelerated atherosclerotic degeneration with an increased risk of thrombosis in all blood vessels, including the carotid arteries. Carotid artery stenosis can manifest in many different ways. The aim of this study is to present the results of our multidetector computerised tomography angiography (MDCTA) analysis of the carotid arteries in patients with primary and secondary APS compared with a control group. Materials and Methods: This study examined 50 patients with primary antiphospholipid syndrome (PAPS) and 50 patients with secondary antiphospholipid syndrome (SAPS). The results were compared with a control group also comprising 50 patients. The groups were analysed with respect to age, sex and the presence of well-established risk factors for vascular disease. The study was conducted using MDCTA, where we analysed the quantitative and qualitative (morphologic) characteristics of carotid artery lesions. Results: Patients from the control group had significantly elevated levels of cholesterol and triglycerides in comparison with patients with PAPS and SAPS (p < 0.001 and p < 0.05). The results show that carotid artery lesions were significantly more common in patients with APS (PAPS, n = 40, CI95: 0.50–0.75, p = 0.0322 and SAFS, n = 54, CI95: 0.59–0.80, p = 0.0004) than within the control group (n = 23). There was a statistically significant difference between patients with APS and the control group with respect to lesions in the distal segments (n = 27, CI95: 0.67–0.95, p = 0.0001), bulbi and proximal segments (n = 21, CI95: 0.84–1.00, p = 0.000005). The number of patients with one lesion (L) (n = 27) was significantly greater than the number of those with three (n = 10, CI95: 0.56–0.86, p = 0.0051) or four (n = 3, CI95: 0.73–0.98, p = 0.00001) lesions. There were also more patients with two lesions (n = 24) than those with four (n = 3) (CI95: 0.71–0.97, p = 0.00005). Carotid artery stenosis was shown as a percentage of the carotid artery lumen diameter (%DS). Stenosis of up to 30%, was more common in patients in the PAPS group (n = 12) than in the control group (n = 3) (CI95: 0.52–0.96, p = 0.0201), while the SAPS group (n = 17) had an even larger disparity (CI95: 0.62–0.97, p = 0.0017). We observed a highly significant difference in the frequency of stenoses between 30% and 50% DS between the PAPS group (n = 24) and the control group (n = 7) (CI95: 0.59–0.90, p = 0.0023), as well as the SAPS group (n = 30) (CI95: 0.65–0.92, p = 0.0002). A qualitative analysis of plaque morphology revealed that patients with PAPS had significantly more soft tissue lesions (n = 23) compared with calcified lesions (n = 2) (CI95: 0.74–0.99, p = 0.00003), as well as more mixed plaques (n = 9) and calcified plaques (n = 2) (CI95: 0.48–0.98, p = 0.0348). Patients within the SAPS group had significantly more soft tissue (n = 35) than calcified lesions (n = 3) (CI95: 0.79–0.98, p = 0.00000021), as well as more mixed lesions (n = 21) compared with calcified (n = 3) (CI95: 0.68–0.97, p = 0.0002). Conclusions: Our study shows that subclinical manifestations of carotid artery lesions were more common in patients with APS. We came to the conclusion that MDCTA is an accurate diagnostic method because it is a safe method that provides us with a great quantity of accurate information about the characteristics of atheromatous plaques, which aids us in the further planning of treatment for patients with APS. © 2023 by the authors. - Some of the metrics are blocked by yourconsent settings
Publication Results of simultaneous application of hyperbaric oxygen and negative pressure wound therapy in diabetic foot ulcers treatment(2019) ;Matic, Predrag (25121600300) ;Cejic, Djordje (57208259504) ;Tanaskovic, Slobodan (25121572000) ;Unic-Stojanovic, Dragana (55376745500) ;Nenezic, Dragoslav (9232882900)Radak, Djordje (7004442548)Background: The aim of this paper is to determine which therapy gives best results regarding process of healing of diabetic foot ulcers among three proposed: only negative pressure wound therapy, only hyperbaric oxygen therapy, and both when used in conjunction. Methods: This bicentric prospective study included 60 patients, and they were, consecutively, assigned to one of three groups. The first group consisted of 20 patients who were treated only by hyperbaric oxygen therapy, second group consisted of 20 patients treated with combined hyperbaric oxygen and negative pressure wound therapy, and third group consisted of 20 patients who were treated only by negative pressure wound therapy. In some cases, previous revascularization of lower limb was performed and patients with poor run-off, without possibility to perform revascularization, were excluded from the study. Results: Patients were predominantly men (56.7%) and mean age was 60.57 years. Majority of patients had ulcers of ischemic origin (45%), in 30% of cases, the reason of foot ulceration was neuropathy, and in 25% of patients, the etiology was combined. During the study, in three patients (5%), minor amputations were observed. Regarding Wagner classification of foot ulcers, most dominant was stage II (χ = 12.618, df = 4, p < 0.05). Statistically significant reduction of wound area was achieved when hyperbaric oxygen and negative pressure wound therapy were used in conjunction comparing to isolated use either of these two modalities of treatment (χ = 116.000, df = 44, p < 0.01). Conclusion: Our data suggests simultaneous use of hyperbaric oxygen therapy and negative pressure wound therapy in diabetic foot ulcer treatment in order to achieve best results. Of great importance is previous wound debridement and successful limb revascularization. © 2019, Research Society for Study of Diabetes in India. - Some of the metrics are blocked by yourconsent settings
Publication Scoring system to predict early carotid restenosis after eversion endarterectomy by analysis of inflammatory markers(2018) ;Tanaskovic, Slobodan (25121572000) ;Radak, Djordje (7004442548) ;Aleksic, Nikola (36105795700) ;Calija, Branko (9739939300) ;Maravic-Stojkovic, Vera (7801670743) ;Nenezic, Dragoslav (9232882900) ;Ilijevski, Nenad (57209017323) ;Popov, Petar (26023653600) ;Vucurevic, Goran (6602813880) ;Babic, Srdjan (26022897000) ;Matic, Predrag (25121600300) ;Gajin, Predrag (15055548600) ;Vasic, Dragan (7003336138)Rancic, Zoran (6508236457)Background: Inflammation is one of the mechanisms that leads to carotid restenosis (CR). The aim of this study was to examine the influence of increased values of inflammation markers (high-sensitivity C-reactive protein [hs-CRP], C3 complement, and fibrinogen) on CR development after eversion carotid endarterectomy (CEA). Methods: A consecutive 300 patients were included in the study, in which eversion CEA was performed between March 1 and August 1, 2010. Demographic data, atherosclerosis risk factors, comorbidities, and ultrasound plaque characteristics were listed in relation to potential risk factors for CR. Serum concentrations of hs-CRP, fibrinogen, and C3 complement were taken just before surgery (6 hours); 48 hours after CEA; and during regular checkups at 1 month, 6 months, 1 year, and 2 years. An “inflammatory score” was also created, which consisted of six predictive values of inflammatory markers (hs-CRP just before and just after CEA, fibrinogen just before and just after CEA, and C3 complement just before and just after CEA) with a maximum score of 6 and a minimum score of 0. At every follow-up visit to the outpatient clinic, ultrasound assessment of the carotid artery for restenosis was done. Results: Our results showed an increased risk of early CR within 1 year in patients with increased hs-CRP before CEA (6 hours) and increased fibrinogen 48 hours after surgery and in patients not taking aspirin after CEA. Sex was determined to be an independent predictor of CR, with female patients having a higher risk (P =.002). Male patients taking aspirin with an inflammatory score >2 had an increased risk for restenosis compared with male patients with inflammatory score <2. Not taking aspirin after CEA and fibrinogen (48 hours) were the strongest predictors, and the Fisher equation incorporating these predictors was used to predict CR. A computer program was created to calculate whether the patient was at high or low risk for CR by selecting whether the patient was taking aspirin (yes or no) and whether fibrinogen was increased 48 hours after CEA (yes or no) and to display the recommended therapeutic algorithm consisting of aspirin, clopidogrel, cilostazol, and statins. Conclusions: Increased hs-CRP before CEA, increased fibrinogen 48 hours after CEA, and not taking aspirin were the main predictors of early CR. With the clinical implementation of the Fisher equation, it is possible to identify patients at high risk for early CR and to apply an aggressive therapeutic algorithm, finally leading to a decreased CR rate. © 2017 Society for Vascular Surgery - Some of the metrics are blocked by yourconsent settings

From January 1991 to December 2004, 5,034 primary ECEAs were performed for high-grade carotid stenosis. Patients treated for restenosis after previous carotid surgery were excluded from the analysis. Group A consisted of 1,714 patients who underwent surgery between 1991 and 1997, and group B consisted of 3,320 patients who underwent surgery between 1998 and 2004. Follow-up included routine clinical evaluation and noninvasive surveillance, with duplex scanning at 1 month after surgery, after 6 months, and annually afterward. Only 3% of patients in group A and 0.6% in group B were asymptomatic, with 23% and 47% of them having preoperative stroke, respectively. In group A, angiography was used for the final diagnosis in 78% of patients. In group B, duplex scanning was performed in 82% of patients and angiography in only 18% (p < .001). Clamping time was shorter in the latter group (12.4 ± 3.1 vs 14.5 ± 4.1 min, p < .01). Introperative shunting and regional anesthesia were rarely performed in both groups (1.4% vs. 0.4%, p < .01, and 2% vs 0.3%, p < .001). Total and neurologic morbidity was significantly higher in group A than in group B (6.41% ± 0.47% vs 4.81% ± 0.53%, p < .001, and 2.14% ± 0.31% vs 1.23% ± 0.29%, p < .001, respectively). Total mortality was also higher in group A than in group B (1.92% ± 0.24% vs 1.36% ± 0.50%, p < .05), but although there was a trend toward lower neurologic mortality, it did not reach statistical significance (1.04% ± 0.5% vs 0.57% ± 0.25%, p = .074). There was a lower rate of nonsignificant restenosis (< 50%) in group B (2% vs 5%, p < .01), but the incidence of restenosis a 50% was identical between the groups (5.5% for both). Our data show that ECEA is a reliable surgical technique for the treatment of atherosclerotic carotid disease. Temporal trends in our patients demonstrated a decline in periopertive mortality and morbidity, despite a higher incidence of preoperative stroke. © BC Decker Inc. All rights reserved.
