Publication Abdominal Aortic Surgery in the Presence of Inferior Vena Cava Anomalies: A Case Series(2017) ;Dimic, Andreja (55405165000) ;Markovic, Miroslav (7101935751) ;Cvetkovic, Slobodan (7006158672) ;Cinara, Ilijas (6602522444) ;Koncar, Igor (19337386500)Davidovic, Lazar (7006821504)Background Left-sided inferior vena cava (LIVC) and duplicated inferior vena cava (DIVC) are rare asymptomatic congenital abnormalities. Unrecognized, these anomalies can be the source of major injuries and cause serious life-threatening bleeding complications especially during abdominal aortic surgery. Methods Retrospective data for patients with 2 major inferior vena cava (IVC) anomalies that underwent aortic surgery over a 13-year period were collected. Patient demographics, type of aortic disease and caval anomaly, surgical approach, type of aortic reconstruction associated with procedure on caval vein, postoperative complications, and in-hospital mortality were recorded. Results There were 9 patients with inferior vena cava (IVC) anomalies who underwent aortic surgery. All of them were men, with a median age of 66.2 years. Seven had an LIVC and 2 had DIVC. Five patients were operated on due to abdominal aortic aneurysm and 4 due to aortoiliac occlusive disease. In all patients, a midline transperitoneal aortic approach was performed. In 5 cases, the left IVC had to be temporarily resected and later reconstructed, and in the other 4 it was just mobilized. There were no postoperative complications except in one patient who developed deep vein thrombosis in the left calf; this was successfully treated with anticoagulant therapy. Conclusion Due to favorable results and low incidence of perioperative complications and in the absence of other associated abdominal pathology, we propose the midline transperitoneal approach with mobilization or temporary resection of LIVC. © 2016 Elsevier Inc. - Some of the metrics are blocked by yourconsent settings

Publication Effect of Intra-operative Intra-arterial Thrombolysis on Long Term Clinical Outcomes in Patients with Acute Popliteal Artery Aneurysm Thrombosis(2020) ;Dragas, Marko (25027673300) ;Zlatanovic, Petar (57201473730) ;Koncar, Igor (19337386500) ;Ilic, Nikola (7006245465) ;Radmili, Oliver (36125483800) ;Savic, Nebojsa (25121804000) ;Markovic, Miroslav (7101935751)Davidovic, Lazar (7006821504)Objective: Acute lower limb ischaemia (ALI) as a result of popliteal artery aneurysm (PAA) thrombosis represents a significant problem. The aim of this study was to investigate outcome of intra-operative intra-arterial thrombolysis in the treatment of acute ischaemia due to PAA thrombosis in terms of major adverse limb events (MALE), overall survival, and intrahospital complications, especially those associated with bleeding. Methods: A total of 156 patients with Rutherford grade IIa and IIb acute ischaemia resulting from PAA thrombosis were admitted between 1 January 2011 and 1 January 2017. The patients were divided into two groups, those who underwent additional treatment with intra-operative intra-arterial thrombolysis (20 patients), and those who did not (136 patients). By using covariables from baseline and angiographic characteristics, a propensity score was calculated for each patient. Each patient who underwent intra-operative thrombolysis was matched to four patients from the non-thrombolysis group. Thus, comparable patient cohorts (20 in the thrombolysis and 80 in the non-thrombolysis group) were identified for further analysis. The primary end point was MALE and the secondary endpoint all cause mortality. Results: After a median follow up of 55 months, the estimated MALE rate was significantly lower in the thrombolysis group (30% vs. 65%, chi square = 10.86, p < .001, log rank test). Also, patients in the thrombolysis group had a significantly lower mortality rate (20% vs. 42.65%, chi square = 3.65, p = .05, log rank test). The thrombolysis group had wound/haematoma related interventions performed more commonly (25% in thrombolysis vs 8%, in non-thrombolysis group), but the difference was not significant (p=.013). There were no cases of major (intracranial and gastrointestinal) bleeding in either group. Conclusion: The data suggest that intra-operative thrombolysis in the treatment of selected patients with ALI due to PAA thrombosis has long term MALE and overall survival benefits, without a significant risk of major, life threatening bleeding complications. © 2019 European Society for Vascular Surgery - Some of the metrics are blocked by yourconsent settings

Publication Evaluation of the renal function using serum Cystatin C following open and endovascular aortic aneurysm repair(2018) ;Ilic, Nikola S (7006245465) ;Opacic, Dragan (56306450600) ;Mutavdzic, Perica (56321930600) ;Koncar, Igor (19337386500) ;Dragas, Marko (25027673300) ;Jovicic, Snezana (12243111800) ;Markovic, Miroslav (7101935751)Davidovic, Lazar (7006821504)Objectives: Controversies regarding renal function impairment after open and endovascular aortic aneurysm repair still exist. The purpose of this study was to evaluate the renal function following open repair and endovascular aneurysm repair using Cystatin C. Methods: This prospective, observational case–control study was conducted in tertiary referral centre over 3 years, starting from 2012. In total, 60 patients operated due to infrarenal AAA either by means of open repair (30 patients) or endovascular aneurysm repair (30 patients) were included in the study. Biochemical markers of renal function (sCr, urea, potassium) were recorded pre-operatively and at these specific time points, immediately after the operation and at discharge, home (third postoperative day, endovascular aneurysm repair group) or from intensive care unit (third postoperative day, open repair group). Multivariate and propensity score adjustments were used to control for the baseline differences between the groups. Results: Creatinine levels in serum remained unchanged during the hospital stay in both groups without significant differences at any time point. Cystatin C levels in endovascular aneurysm repair patients significantly increased postoperatively and restored to values comparable to baseline at the discharge (0.865 ± 0.319 vs. *0.962 ± 0.353 vs. 0.921 ± 0.322, *p < 0.001). Cystatin C levels in patients treated with the open surgery was decreasing over time but not statistically significant comparing to Cystatin C values at the admission. However, decrease in Cystatin C serum levels in patients treated with conventional surgery resulted in statistically significant lower values compared to endovascular aneurysm repair patients both postoperatively and at the time of discharge (0.760 ± 0.225 vs. 0.962 ± 0.353, p < 0.05; 0.750 vs. 0.156, p < 0.05). Both multivariate linear regression models and propensity score adjustment confirm that, even after correction for previously observed intergroup differences, type of surgery, i.e. endovascular aneurysm repair is independently associated with the higher levels of Cystatin C both postoperatively and at the discharge. Conclusions: Dynamics of Cystatin C levels have been proven as a more vulnerable marker of renal dysfunction. Endovascular aneurysm repair is associated with higher levels of kidney injury markers. © 2017, © The Author(s) 2017. - Some of the metrics are blocked by yourconsent settings
Publication Female and obese patients might have higher risk from surgical repair of asymptomatic carotid artery stenosis(2015) ;Davidovic, Lazar (7006821504) ;Koncar, Igor (19337386500) ;Dragas, Marko (25027673300) ;Markovic, Miroslav (7101935751) ;Ilic, Nikola (7006245465) ;Mutavdzic, Perica (56321930600) ;Banzic, Igor (36518108700)Ristanovic, Natasa (56716304700)Background To investigate the results after carotid endarterectomy performed for asymptomatic carotid stenosis (ACS) in a single high-volume center and define the factors that increase perioperative stroke and mortality rate. Methods This observational study that analyzes prospectively collected data includes 1,567 patients with ACS operated in the period between 2007 and 2012. Results Most patients were male, 1,037 (66.18%), with mean age of 63.6 years. Perioperative death rate was 0.38%. The most frequent causes of death were stroke and myocardial infarction. The total perioperative stroke/transient ischemic attack rate was 2.81%. Logistic regression analysis confirmed that females (P = 0.028) and obese (P = 0.060) patients have higher risk of perioperative stroke after surgical repair of ACS with odds ratio (OR) of 2.008 and 2.342. The early mortality was significantly higher in candidates for coroanary artery bypass grafting (P = 0.018). Stroke and mortality are related to obesity and ischemic heart disease with OR of 2.407 and 2.097, respectively. Conclusions According to our results, female and obese patients are prone to stroke after carotid endarterectomy. Further study of the effects of female gender and obesity on surgical outcomes is warranted before medical therapy is considered the preferred treatment for these patients. © 2015 Elsevier Inc.

Publication Identification of Risk Factors and Development of Predictive Risk Score Model for Mortality after Open Ruptured Abdominal Aortic Aneurysm Repair(2022) ;Tomic, Ivan (54928165800) ;Zlatanovic, Petar (57201473730) ;Markovic, Miroslav (7101935751) ;Sladojevic, Milos (35184234700) ;Mutavdzic, Perica (56321930600) ;Trailovic, Ranko (57006712200) ;Jovanovic, Ksenija (57376155800) ;Matejevic, David (57657574700) ;Milicic, Biljana (6603829143)Davidovic, Lazar (7006821504)Background and Objectives: Despite the relatively large number of publications concerning the validation of these models, there is currently no solid evidence that they can be used with absolute precision to predict survival. The goal of this study is to identify preoperative factors that influenced 30-day mortality and to create a predictive model after open ruptured abdominal aortic aneurysm (RAAA) repair. Materials and Methods: This was a retrospective single-center cohort study derived from a prospective collected database, between 1 January 2009 and 2016. Multivariate logistic regression analysis was used to identify all significant predictive factors. Variables that were identified in the multivariate analysis were dichotomized at standard levels, and logistic regression was used for the analysis. To ensure that dichotomized variables were not overly simplistic, the C statistic was evaluated for both dichotomized and continuous models. Results: There were 500 patients with complete medical data included in the analysis during the study period. Of them, 37.6% were older than 74 years, and 83.8% were males. Multivariable logistic regression showed five variables that were predictive of mortality: age > 74 years (OR = 4.01, 95%CI 2.43–6.26), loss of consciousness (OR = 2.21, 95%CI 1.11–4.40), previous myocardial infarction (OR = 2.35, 95%CI 1.19–4.63), development of ventricular arrhythmia (OR = 4.54, 95%CI 1.75–11.78), and DAP < 60 mmHg (OR = 2.32, 95%CI 1.17–4.62). Assigning 1 point for each variable, patients were stratified according to the preoperative RAAA mortality risk score (range 0–5). Patients with 1 point suffered 15.3% mortality and 3 points 68.2% mortality, while all patients with 5 points died. Conclusions: This preoperative RAAA score identified risk factors readily assessed at the bedside and provides an accurate prediction of 30-day mortality after open repair of RAAA. © 2022 by the authors.

Publication Impact of diabetes mellitus on early outcome of carotid endarterectomy(2019) ;Dimic, Andreja (55405165000) ;Markovic, Miroslav (7101935751) ;Vasic, Dragan (7003336138) ;Dragas, Marko (25027673300) ;Zlatanovic, Petar (57201473730) ;Mitrovic, Aleksandar (57194042781)Davidovic, Lazar (7006821504)Background: Diabetes mellitus increases the risk of ischaemic stroke in the general population but its impact on early outcome after the carotid endarterectomy (CEA) is controversial with conflicting results. Patients and methods: This prospective study includes 902 consecutive CEAs. Patients were divided into non-diabetic and diabetic groups and subsequently analysed. Early outcomes in terms of 30-day stroke and death rates were then analysed and compared. Results: There were 606 non-diabetic patients. Among 296 diabetic patients, 83 were insulin-dependent. The cumulative TIA/stroke rate was statistically higher in the diabetic group (2.6 vs. 5.7 %, P = 0.02). Stroke was more frequent in the diabetic group (2.0 vs. 4.4 %, P = 0.04) comparedto TIA (0.7 vs. 1.4 %, P = 0.45). Mortality was statistically more frequent in diabetic patients (0.2 vs. 1.7 %, P = 0.01). The 30-day stroke/death rate (2.6 vs. 5.7 %, P = 0.02) was also statistically higher in the diabetic group. Factors that were identified to increase risk of death and stroke in multivariate analysis were: use of insulin for blood glucose control (OR = 2.47, 95 % CI 1.61–4.68, P = 0.01), higher low-density lipoprotein cholesterol value (OR = 1.52, 95 % CI 1.15–2.22, P < 0.01), presence of coronary disease (OR = 2.04, 95 % CI 1.40–3.31, P = 0.03), peripheral artery disease (OR = 2.14, 95 % CI 1.34–3.65, P = 0.02), complicated plaque (OR = 1.77, 95 % CI 1.11–3.68, P = 0.03), contralateral carotid artery occlusion (OR = 2.37, 95 % CI 1.25–4.74, P = 0.02), shunt use (OR = 3.46, 95 % CI 1.18–7.10, P < 0.01), and among diabetic patients higher HbA1c levels (OR = 1.28, 95 % CI 1.05–1.66, P = 0.03). Clamp toleration was associated with lower risk of death and stroke rates (OR = 0.43, 95 % CI 0.23–0.76, P < 0.01). Conclusions: In our study, perioperative neurological complications and mortality were statistically higher in diabetic patients compared to non-diabetic patients during CEA. Further research will have to show whether other treatment modalities of carotid artery stenosis and better glycaemia and dyslipidaemia controlling in diabetics can reduce this risk. © 2018 Hogrefe. - Some of the metrics are blocked by yourconsent settings

(57218353267)Vascular compression syndromes (VCS) are rare diseases, but they may cause significant symptoms interfering with the quality of life (QoL) of patients who are often in their younger age. Given their infrequent occurrence, multiform clinical and anatomical presentation, and absence of dedicated guidelines from scientific societies, further knowledge of these conditions is required to investigate and treat them using modern imaging and surgical (open or endovascular) techniques. This consensus document will focus on known VCS, affecting the arterial and venous system. The position paper, written by members of International Union of Angiology (IUA) Youth Committee and senior experts, will show an overview of pathophysiology, diagnostic, and therapeutical approaches for patients with VCS. Furthermore, this document will provide also unresolved issues that require more research that need to be addressed in the future. © 2023 EDIZIONI MINERVA MEDICA. - Some of the metrics are blocked by yourconsent settings
Publication Late Complication after Thoracic Endovascular Aortic Repair: What Is the Role of an Open Surgical Conversion?(2018) ;Davidovic, Lazar (7006821504) ;Sladojevic, Milos (35184234700) ;Koncar, Igor (19337386500) ;Markovic, Miroslav (7101935751) ;Ulus, Tulga (6603588829) ;Ilic, Nikola (7006245465) ;Dragas, Marko (25027673300) ;Cvetic, Vladimir (57189236266)Rancic, Zoran (6508236457)Background: The aim was to evaluate the causes of thoracic endovascular aortic repair (TEVAR) failure and conversion to open surgery (COS) in a vascular center with high-volume open surgery and low-volume TEVAR procedures. Methods: A total of 8 patients (6 men; mean age, 55.14 years) underwent COS after TEVAR. The indications for COS, intraoperative strategy, and early postoperative and mid-follow-up results were analyzed. Results: The indications for COS were persistent proximal type I endoleak with progressive aneurysm enlargement in 2 patients, type III endoleak in 1 patient, progressive aneurysm enlargement with no endoleak in 1 patient, stent-graft migration in 2 patients, secondary aortoesophageal fistula in 1 patient, secondary aortoesophageal and aortobronchial fistula in 1 patient, and distal progression of the aneurysmal disease in 2 patients. In all but one patient, thoracic stent grafts were explanted, and replacement with a Dacron graft was performed using left partial cardiopulmonary bypass. In the remaining patients with disconnection of the distal component and unfavorable anatomy, the proximal stent graft was recycled, and the Dacron prosthesis was sewn to it. Patients with secondary aortobronchial and aortoesophageal fistulas required additional bronchial and esophageal repair. The in-hospital mortality rate was 50% (4 patients). Four (50%) patients were followed up between 7 and 24 months (mean, 16.75 months) without mortality. Conclusions: COS after TEVAR has a high mortality rate, and endovascular techniques should be considered as the first line of treatment. Those procedures should be performed by surgeons experienced in open repair which one might expect to be a challenging problem in the era of endovascular therapy. © 2017 Elsevier Inc. - Some of the metrics are blocked by yourconsent settings
Publication Magnetic resonance imaging assessment of proteolytic enzyme concentrations and biologic properties of intraluminal thrombus in abdominal aortic aneurysms(2020) ;Sladojevic, Milos (35184234700) ;Stanojevic, Zeljka (55976632400) ;Koncar, Igor (19337386500) ;Zlatanovic, Petar (57201473730) ;Vidicevic, Sasenka (57205259671) ;Tosic, Jelena (55744333300) ;Isakovic, Aleksandra (57202555421) ;Markovic, Miroslav (7101935751)Davidovic, Lazar (7006821504)Objective: The aim of the study was to determine whether magnetic resonance imaging (MRI) can be used in assessment of biologic activity of intraluminal thrombus (ILT) and proteolytic processes of the abdominal aortic aneurysm wall. Methods: Using MRI, 50 patients with asymptomatic infrarenal abdominal aortic aneurysm were analyzed at the maximum aneurysm diameter on T1-weighted images in the arterial phase after administration of contrast material. Relative ILT signal intensity (SI) was determined as the ratio between ILT SI and psoas muscle SI. During surgery, the full thickness of the ILT and the adjacent part of the aneurysm wall were harvested at the maximal diameter for biochemical analysis. The concentrations of matrix metalloproteinase 9 and neutrophil elastase (NE/ELA) were analyzed in harvested thrombi, and the concentrations of collagen type III, elastin, and proteoglycans were analyzed in harvested aneurysm walls. Results: A significant positive correlation was found between the NE/ELA concentration of the ILT and the relative SI (ρ = 0.309; P =.029). Furthermore, a negative correlation was observed between the elastin content of the aneurysm wall and the relative SI (ρ = −0.300; P =.034). No correlations were found between relative SI and concentration of matrix metalloproteinase 9, NE/ELA, collagen type III, or proteoglycan 4 in the aneurysm wall. Conclusions: These findings indicate a potential novel use of MRI in prediction of thrombus proteolytic enzyme concentrations and the extracellular matrix content of the aneurysm wall, thus providing additional information for the risk of potential aneurysm rupture. © 2019 Society for Vascular Surgery - Some of the metrics are blocked by yourconsent settings
Publication Morphological and Biomechanical Features in Abdominal Aortic Aneurysm with Long and Short Neck—Case-Control Study in 64 Abdominal Aortic Aneurysms(2017) ;Koncar, Igor B. (19337386500) ;Nikolic, Dalibor (57548845900) ;Milosevic, Zarko (36975934300) ;Ilic, Nikola (7006245465) ;Dragas, Marko (25027673300) ;Sladojevic, Milos (35184234700) ;Markovic, Miroslav (7101935751) ;Filipovic, Nenad (35749660900)Davidovic, Lazar (7006821504)Background Both, open and endovascular, procedures are related to higher complication rate in abdominal aortic aneurysm (AAA) with shorter neck. Previous study showed that long-neck AAA might have lower risk of rupture. Estimation of biomechanical forces in AAA improves rupture risk assessment. The aim of this study was to compare morphological features and biomechanical forces in the short- and long-neck AAA with threshold of 15 mm. Methods Digital Imaging and Communication in Medicine images of 64 aneurysms were prospectively collected and analyzed in a case-control study. Using commercially available software, Peak wall Stress (PWS) and Rupture Risk Equivalent Diameter (RRED) were determined. Difference between the maximal aneurysm diameter (MAD) and RRED was calculated and expressed as an absolute and relative (percentage of the MAD) value. In addition, volume of intraluminal thrombus (ILT) was calculated and expressed relative to AAA volume. Results Study included 64 AAA divided in group with long (36, 56.25%), and short (28, 43.75%) neck. There was no correlation between neck length and MAD, PWS, and RRED (P = 0.646, P = 0.421, and P = 0.405, respectively). Relative ILT volume was greater in the short-neck aneurysms (P = 0.033). Relative difference between RRED and MAD was −4% and −14.8% in short- and long-neck aneurysms, respectively (P = 0.029). The difference between RRED and MAD was positive in 14/28 patients (50%) with short neck and in 6/35 patients (17.14%) with long neck (P = 0.011). Conclusions Based on our biomechanical analysis, in AAA with neck longer than 15 mm rupture risk might be lower than the risk estimated by its diameter. It might be explained with lower relative volume of ILT. © 2017 Elsevier Inc. - Some of the metrics are blocked by yourconsent settings
Publication Open Repair of AAA in a High Volume Center(2017) ;Davidovic, Lazar B. (7006821504) ;Maksic, Milanko (55353497600) ;Koncar, Igor (19337386500) ;Ilic, Nikola (7006245465) ;Dragas, Marko (25027673300) ;Fatic, Nikola (56108975900) ;Markovic, Miroslav (7101935751) ;Banzic, Igor (36518108700)Mutavdzic, Perica (56321930600)Objective: To assess results of open repair (OR) of AAA in a single high volume center. Methods: We analyzed prospectively collected data of 450 patients who underwent elective OR of AAA at the Clinic for Vascular and Endovascular Surgery of the Serbian Clinical Centre in the period between January 2013 and September 2014. Results: Postoperative death occurred in seven patients (1. 55%) during the first 30 postoperative days. The mortality was caused by: uncontrolled bleeding-1, acute myocardial infarction-1, ischemic colitis-2, MOFS-2, sepsis due to infection and dehiscence of laparotomy wound-1. Coronary artery disease (OR 3.89; CI 0.85–17.7; p = 0.0058), postoperative acute myocardial infarction (OR 29.9; CI 2.56–334.95; p = 0.0053), chronic renal failure (OR 7.5; CI 1.35–8.5; p = 0.0073), colonic necrosis (OR 88.2; CI 4.77–1629.69; p = 0.0026), occlusion of the both hypogastric arteries and the inability to preserve at least one hypogastric artery (OR 17.4; CI 1.99–178.33; p = 0.0230), aortobifemoral reconstruction (OR 9.06; CI 1.76–46.49; p = 0.016), significant perioperative bleeding (>2 L) (OR 7.32; CI 1.31–10.79; p = 0.0001), hostile abdomen (OR 5.25; CI 1.3–21.1; p = 0.0055), inflammatory aneurysm (OR 13.99; CI 2.88–65.09; p = 0.0002), supraceliac aortic cross-clamping (OR 18.7; CI 3.8–90.6; p = 0.0003), prolonged aortic cross-clamping (>60 min) (OR 14.25; CI 2.75–64.5; p = 0.0003), the intraoperative hypotension (OR 6.61; CI 0.71–61.07; p = 0.0545), the prolonged operation (>240 min) (OR 8.66; CI 0.91–81.56; p = 0.0585) and complete dehiscence of the laparotomy (OR 44.1; CI 3.39–572.78; p = 0.0396) increased the 30-day mortality in our study. Conclusions: Early mortality after open repair of AAA in high volume center might be very low due to experienced multidisciplinary team. Centralized open aortic surgery might be solution for effective treatment of patients with unsuitable anatomy or for young patients with long life expectancy. © 2016, Société Internationale de Chirurgie. - Some of the metrics are blocked by yourconsent settings
Publication Open repair of ruptured abdominal aortic aneurysm with associated horseshoe kidney(2018) ;Davidovic, Lazar B. (7006821504) ;Markovic, Miroslav (7101935751) ;Kostic, Dusan (7007037165) ;Zlatanovic, Petar (57201473730) ;Mutavdzic, Perica (56321930600)Cvetic, Vladimir (57189236266)BACKGROUND: Ruptured abdominal aortic aneurysms (RAAA) with concomitant horseshoe kidney (HK) present a unique challenge at the time of repair. The aim of this article was to propose the most rationale strategy during open repair (OR) of RAAAin the presence of HK. METHODS: We identified and analyzed all patients treated at the clinic due to RAAA and HK. An extensive search was performed on all articles published up to August of 2017 describing open and endovascular repair of RAAAwith concomitant horseshoe kidney. The following data were extracted and analyzed: patient number, number of renal arteries, Crawford classification of horseshoe kidney vascularization, type of aortic reconstruction, management with renal arteries, 30-day kidney failure and outcome. RESULTS: Transperitoneal approach followed by supraceliac aortic cross clamping without the division of the renal isthmus occurred in all our six cases. Four of them required additional procedures with accessory renal arteries after aortic replacement. Three of patients (50%) died during the first 30 postoperative days, while one developed transitory renal insufficiency. The renal isthmus was preserved in 43.90% and divided in 46.34% of cases. Crawford type I of HK vascularization was presented in 21.95% of cases, type II also in 39.02%, while the type III in 19.51% of cases. In 46.33% of cases a procedure with renal arteries was necessary. In 26.82% accessory renal arteries were ligated, while in 19.51% preserved (reattachment or aorto-renal bypass). Thirty-day mortality was 21.95%, while the incidence of postoperative renal failure was also 21.95%. There was not significant correlation between the renal artery ligation and the postoperative renal failure (r=-0.81, P=0.59). CONCLUSIONS: Transperitoneal approach should be preferred during urgent ORof RAAAwith concomitant HK. Asupraceliac aortic cross clamping and the placement of occlusive Fogarty catheters into both iliac arteries are recommended for proximal and distal bleeding control. Preservation of accessory renal arteries that are larger than 3 mm in diameter or supply more than 30% of renal parenchima is recommended. The division of the renal isthmus should be avoided if vascularized. It seems that renal arteries could be covered in emergency EVARwithout any implications on postoperative kidney function, allowing broader aplication of endovascular treatment for thesse patients. © 2018 EDIZIONI MINERVAMEDICA. - Some of the metrics are blocked by yourconsent settings
Publication Open Surgical Treatment of Secondary Aortoesophageal and Aortobronchial Fistula after Thoracic Endovascular Aortic Repair and Esophagocoloplasty in a Second Procedure(2017) ;Sladojevic, Milos (35184234700) ;Bjelovic, Milos (56120871700) ;Ilic, Nikola (7006245465) ;Mutavdzic, Perica (56321930600) ;Koncar, Igor (19337386500) ;Dragas, Marko (25027673300) ;Markovic, Miroslav (7101935751)Davidovic, Lazar (7006821504)Aortoesophageal (AEF) and aortobronchial fistula (ABF) after thoracic endovascular aortic repair (TEVAR) are rare complications with catastrophic consequences without treatment. In this case report, we presented a patient with AEF and ABF after TEVAR successfully treated with endograft explantation and replaced by Dacron graft followed by esophagectomy and left principal bronchus repairing. We report a patient with AEF and ABF after TEVAR who was evaluated due to dysphagia and chest pain followed by hematemesis and hemoptysis. Endoscopic examination revealed lesion of the esophageal wall with chronic abscess formation and stent-graft protrusion into the cavity. Patient was operated on with extracorporeal circulation. AEF and ABF were confirmed intraoperatively. Endograft was explanted and in situ reconstruction of thoracic aorta was carried out with tubular Dacron 22-mm prosthesis wrapped with omental flap. After aortic reconstruction, esophageal mucosal stripping was performed with cervical esophagostomy, pyloromyotomy, and Stamm-Kader gastrostomy for nutrition. In addition, omentoplasty of the defect in the left principal bronchus was performed. To re-establish peroral food intake esophagocoloplasty was carried out 8 months after previous surgery utilizing transversosplenic segment of the colon and retrosternal route. In very selective cases, stent-graft explantation and in situ reconstruction with Dacron graft covered by omental flap followed by esophagectomy and bronchus repairing permit adequate debridement reducing the risk of mediastinitis and graft infection and allow a safe esophageal reconstruction in a second procedure. © 2017 Elsevier Inc. - Some of the metrics are blocked by yourconsent settings
Publication Open Treatment of Blunt Injuries of Supra-Aortic Branches: Case Series(2016) ;Sladojevic, Milos (35184234700) ;Markovic, Miroslav (7101935751) ;Ilic, Nikola (7006245465) ;Pejkic, Sinisa (57189038513) ;Banzic, Igor (36518108700) ;Djoric, Predrag (6507877839) ;Koncar, Igor (19337386500) ;Tomic, Ivan (54928165800)Davidovic, Lazar (7006821504)Background Blunt injuries of the supra-aortic branches are rare entity, and majority of patients die before arrival at the hospital. Those who arrive alive require complex and fast procedure that requires sternotomy. We report 3 successfully managed cases. Case Reports We report 3 patients with injury of supra-aortic branches. One was treated urgently due to longitudinal rupture on the posterior wall of innominate artery after car accident, and another 2 had chronic false aneurysm located at the very orifice of the right subclavian and left common carotid artery. In first and second patient bypass grafting with a hand-made, Y-shaped, 8-mm Dacron graft from the ascending aorta to the right common carotid and proximal right subclavian artery were performed, whereas in last 1 bypass grafting from the ascending aorta to the cervical part of the left common carotid artery was performed. In our facility, there were no possibilities for any endovascular treatment. Conclusions When endovascular technology is not available, open surgical repair of blunt injuries of supra-aortic vessels can be performed without complications. No matter to that, endovascular and hybrid procedures should be considered whenever possible. © 2016 Elsevier Inc. - Some of the metrics are blocked by yourconsent settings
Publication Pain associated with carotid artery surgery performed under carotid plexus block: Preemptive analgesic effect of ketorolac(2006) ;Sindjelic, Radomir (6602803313) ;Davidovic, Lazar (7006821504) ;Vlajkovic, Gordana (56619947100) ;Markovic, Miroslav (7101935751)Kuzmanović, Ilija (6506347823)Carotid artery surgery (CAS) performed under cervical plexus block is frequently associated with significant intra- and postoperative pain. To evaluate whether preoperative administration of ketorolac may improve analgesia in this type of surgery, 80 patients scheduled for CAS under cervical plexus block were randomly allocated to receive intravenously either 30 mg of ketorolac or placebo 30 minutes before surgery. Verbal rating scale pain scores during surgery and 3 and 6 hours after surgery, the number of patients requiring additional analgesia, and the total analgesic consumption both during and within 6 hours after surgery were significantly lower, whereas the time to first postoperative analgesia was significantly shorter in the ketorolac group than in the control group. The results of this prospective, randomized, double-blind study show that a single 30 mg dose of ketorolac administered intravenously 30 minutes before surgery reduces intraoperative pain and preempts postoperative pain in patients undergoing CAS under carotid plexus block. © BC Decker Inc.

Publication Role of recombinant factor VIIa in the treatment of intractable bleeding in vascular surgery(2011) ;Končar, Igor B. (19337386500) ;Davidović, Lazar B. (7006821504) ;Savić, Nebojša (25121804000) ;Sindelić, Radomir B. (6602803313) ;Ilić, Nikola (7006245465) ;Dragas, Marko (25027673300) ;Markovic, Miroslav (7101935751)Kostic, Dusan (7007037165)Background Most recent publications have shown that the recombinant form of activated factor VII (rFVIIa; NovoSeven, Novo Nordisk A/S, Bagsværd, Denmark) induces excellent hemostasis in patients with severe intractable bleeding caused by trauma and major surgery. The purpose of this study was to determine the influence of rFVIIa on the treatment of intractable perioperative bleeding in vascular surgery when conventional hemostatic measures are inadequate. Materials and Methods There were two groups of patients: the NovoSeven group (group N), 10 patients with ruptured abdominal aortic aneurysms (RAAAs) and 14 patients operated on due to thoracoabdominal aortic aneurysms (TAAAs); the control group (group C), 14 patients with RAAAs and 17 patients with TAAAs. All patients suffered intractable hemorrhage refractory to conventional hemostatic measures, while patients from group N were additionally treated with rFVIIa. Results Postoperative blood loss was significantly lower in group N treated with rFVII (P < .0001). Postoperative administration of packed red blood cells, fresh frozen plasma, and platelets was lower in patients from group N, (P < .0001). Successful hemorrhage arrest was reported in 21 patients (87.5%) treated with rFVIIa, and in 9 patients (29.03%) in group C (P < .001). Thirty-day mortality in these two groups significantly differed. The mortality rate was 12.5% (3 patients) in group N and 80.65% (25 patients) in group C (P < .0001). Conclusion Our findings suggest that rFVIIa may play a role in controlling the intractable perioperative and postoperative bleeding in surgical patients undergoing a repair of RAAAs and TAAAs. Certainly, prospective randomized trials are necessary to further confirm the efficacy and cost-effectiveness of rFVIIa in these patients. © 2011 Society for Vascular Surgery. - Some of the metrics are blocked by yourconsent settings
Publication Serbia(2021) ;Davidovic, Lazar B. (7006821504)Markovic, Miroslav (7101935751)At the beginning of the second decade of the 20th century, Serbian surgeon V. Soubbotich reported his experience regarding treatment of vascular injuries from the Balkan Wars (1912-13). At the end of the 20th century, the former Yugoslavia experienced civil war, closely followed by the North Atlantic Treaty Organisation (NATO) bombing of Serbia. As a result of these unpleasant facts, the author’s generation of vascular surgeons had the opportunity to treat a significant number of vascular injuries. In the absence of national registers, the most reliable data related to vascular injuries in Serbia can be found in the database of the Clinic for Vascular and Endovascular Surgery of the Serbian Clinical Center. This database contains records from patients with 590 peripheral arterial injuries sustained between 1992 and 2001. Of these injuries, 140 were war-related and 273 occurred in the civilian settings. During the 2002-18 (“peacetime”) period, an additional number of 870 vascular injuries was included in the register. These data revealed that the treatment of vascular injury in the region of the Western Balkans is associated with two main problems. The first one is inefficient transportation of the injured; the second is the lack of qualified vascular surgeons. The result is a significant number of redo procedures, usually followed by decreased functionality of the extremity. In the majority of cases with vascular injuries, open surgical repair is the most common option. On the other hand, in most developed countries, residents and young vascular surgeons do not have sufficient experience in the conventional treatment of vascular trauma; for this reason additional education and training in open vascular surgery is still needed. Young vascular surgeons and residents in Serbia do not lack this training. © 2022 Elsevier Inc.
