Publication An Isolated Aneurysm of the Abdominal Aorta in a Patient with Marfan Syndrome—A Case Report(2020) ;Mutavdzic, Perica (56321930600) ;Dragas, Marko (25027673300) ;Kukic, Biljana (6506390933) ;Stevanovic, Ksenija (57376155800) ;Končar, Igor (19337386500) ;Ilić, Nikola (7006245465) ;Tomic, Ivan (54928165800) ;Sladojevic, Milos (35184234700)Davidovic, Lazar (7006821504)We present a case of successfully treated abdominal aortic aneurysm in a 24-year-old patient with Marfan syndrome. After initial physical and ultrasound examination, the multislice computed tomography (MSCT) scan revealed infrarenal aortic aneurysm of 6 cm in diameter, 10 cm long, along with slightly dilated iliac arteries. However, dimensions of aortic root, aortic arch, and descending suprarenal aorta were within normal limits. Further on, because the patient presented with signs of impending rupture, an urgent surgical intervention was performed. The patient was discharged in good general medical condition 7 days after surgery. After 6 months of follow-up, the patient's condition was satisfying and no MSCT signs of further aortic dissection/aneurysm were identified. To the best of our knowledge, a case of successful management of a patient with Marfans syndrome and truly isolated infrarenal and symptomatic abdominal aortic aneurysm has not been described in the literature before. © 2019 Elsevier Inc. - Some of the metrics are blocked by yourconsent settings
Publication Arterial thoracic outlet syndrome: a 30-year experience in a high-volume referral center(2022) ;Davidovic, Lazar B. (7006821504) ;Zlatanovic, Petar (57201473730) ;Dragas, Marko (25027673300) ;Koncar, Igor (19337386500) ;Micic, Mihajlo (57996892900)Matejevic, David (57657574700)BACKGROUND: The purpose of this study was to assess the clinical presentation and contemporary management of arterial thoracic outlet syndrome (TOS) in high-volume referral center. METHODS: We conducted a retrospective review of a prospectively maintained database of patients with TOS of any etiology between January 1st 1990 and 2021. Supra-, or combined supra-/infraclavicular approaches have been used for decompression/vascular reconstructions. The group was divided into two equal time periods: period 1 (1990-2006, N.=27) and period 2 (2006-2021, N.=36). RESULTS: Sixty-three consecutive patients underwent surgical treatment due to arterial TOS. Period 2 had more patients who were asymptomatic (N.=16, 44.4% vs. N.=0, 0%, P<0.001) and those presenting with critical hand ischemia (N.=12, 33.3% vs. N.=0, 0%, P=0.01), while acute limb ischemia was more common in period 1 (N.=16, 59.2% vs. N.=5, 13.9%, P<0.001). SA compression without lesion was more common in period 2 (N.=16, 44.4% vs. N.=0, 0%, P<0.001), while SA intimal damage with mural thrombus formation was more common in the period 1 (N.=12, 44.4% vs. N.=1, 2.7%, P<0.001). Decompression as an isolated procedure was performed in 25.4% (N.=16) of all asymptomatic patients, while combined decompressive and vascular procedure in 71.4% (N.=45) of patients. The most common postoperative complication was pneumothorax (N.=7, 11.1%). CONCLUSIONS: The supraclavicular approach with its modifications provides adequate decompression and allows also repair or reconstruction of the SA, as well as complete additional revascularization of the upper extremity without the need for further patient repositioning. While treatment methods and early outcomes have not changed significantly over time, there has been a trend towards different clinical and SA pathomorphological presentation. - Some of the metrics are blocked by yourconsent settings
Publication Carotid replacement with Dacron graft in 292 patients(2016) ;Koncar, Igor (19337386500) ;Ribac, Jelena Z (57191845324) ;Ilic, Nikola S (7006245465) ;Dragas, Marko (25027673300) ;Mutavdzic, Perica (56321930600) ;Tomic, Ivan Z (54928165800) ;Ristanovic, Natasa (56716304700) ;Kostic, Dusan (7007037165)Davidovic, Lazar (7006821504)Introduction: In case of highly atherosclerotic carotid process, carotid graft replacement might be a potential solution for successful procedure. Many studies evaluated the results of vein and polytetrafluorethilen (PTFE) graft usage at the carotid bifurcation, while the experience on the Dacron graft due to extensive atherosclerotic process is missing. The aim of our study was to evaluate 30-day and long-term results of the Dacron graft on carotid artery used in patients with extensive atherosclerotic disease. Material and methods: This retrospective study analysed early and long-term neurological outcome as well as Dacron graft patency in patients operated with carotid reconstruction. Early results were confirmed by follow-up clinical examination, whereas late results were assessed by follow-up clinical examination as well as duplex sonographic examination at least 1 year after the surgery. As for statistical methods we used descriptive analysis tests, Chi-square test, and logistic regression. Results: Carotid graft replacement was performed in 292 patients, before endarterectomy in 155 (53.09%), or after already attempted unsuccessful eversion endarterectomy in 137 (46.91%). Nineteen (6.5%) patients had a stroke due to ipsilateral and contralateral ischaemia or haemorrhagic in 17 (5.8%), 1 (0.3%) and 1 (0.3%) patients, respectively. Significantly higher rate of strokes occurred when the graft reconstruction was used after the failure of endarterectomy (8.5% vs. 3.5%, p = 0.029). Stroke and death rate was 7.19%. Factors that increased risk of early stroke were the length of plaque in the internal carotid artery measured intraoperatively (p = 0.025) and the surgical tactic to perform graft reconstruction after attempted extensive endarterectomy (p = 0.029). Conclusion: Low number of patients with carotid stenosis has extensive atherosclerotic process longer than 4 cm that might jeopardise eversion endarterectomy. Carotid graft replacement with Dacron graft provide early results that are comparable with other conduits; however, in such patients reconstruction should be selected individually based on surgical experience and anatomical distribution of stenotic disease. Due to high risk of stroke, only symptomatic patients with such extensive atherosclerotic disease should be operated. © 2016, © The Author(s) 2016. - Some of the metrics are blocked by yourconsent settings
Publication Combined Impact of Chronic Kidney Disease and Contrast Induced Acute Kidney Injury on Long-term Outcomes in Patients with Acute Lower Limb Ischaemia(2018) ;Zlatanovic, Petar (57201473730) ;Koncar, Igor (19337386500) ;Dragas, Marko (25027673300) ;Ilic, Nikola (7006245465) ;Sladojevic, Milos (35184234700) ;Mutavdzic, Perica (56321930600) ;Tomic, Ivan (54928165800) ;Kostic, Dusan (7007037165)Davidovic, Lazar (7006821504)Introduction: Acute lower limb ischaemia (ALI) is the sudden onset of decreased arterial perfusion with imminent threat to limb viability. Contrast induced acute kidney injury (CI-AKI) is one of the complications that increases mortality in patients who undergo contrast imaging in coronary procedures. The goal of this study is to evaluate the impact of chronic kidney disease (CKD) and CI-AKI on long-term clinical outcomes in patients with ALI undergoing lower limb revascularisation. Methods: A total 1017 consecutive patients with acute lower limb ischaemia who were admitted between July 1, 2006, and January 1, 2017, were retrospectively reviewed. Patients who had end stage renal disease, those who had end stage heart and malignant disease and died within 7 days of limb revascularisation, and those who did not undergo angiography were excluded. Thus 546 patients were included in the final analysis. Patients were classified as with or without CKD and were then subdivided according to the presence or absence of the development of CI-AKI, defined as an increase in serum creatinine of ≥0.5 mg/dL or by ≥25% from the baseline value within the first 72 h after contrast exposure. The primary end point was all cause mortality and secondary major adverse limb event (MALE). Results: Both CKD and CI-AKI were associated with the highest rate of all cause mortality (chi square = 55.77, d.f. = 1, p <.01, log rank test) and MALE (chi square = 79.07, d.f. = 1, p <.01, log rank test). The presence of CKD and CI-AKI were significant risk factors associated with long-term all cause mortality (HR = 2.61, p <.01) and MALE (HR = 2.87, p <.01). Conclusion: In patients with ALI undergoing lower limb revascularisation, both CKD and CI-AKI were significantly associated with poor long-term outcomes compared with either CKD or CI-AKI alone. Further studies are required to assess this association and to confirm the combined effect of CKD and CI-AKI on long-term clinical outcomes. © 2018 European Society for Vascular Surgery - Some of the metrics are blocked by yourconsent settings
Publication Deep venous thrombosis in patients with atresia of the inferior vena cava and right kidney hypoplasia (KILT syndrome): Systematic review of the literature(2024) ;Pantic, Nikola (57221630977) ;Cvetkovic, Mirjana (58716866000) ;Milin-Lazovic, Jelena (57023980700) ;Vukmirovic, Jelica (58973602200) ;Pavlovic, Aleksandar (58553335800) ;Virijevic, Marijana (36969618100) ;Pravdic, Zlatko (57221636770) ;Kozarac, Sofija (58973969700) ;Sabljic, Nikica (57221634280) ;Suvajdzic-Vukovic, Nada (36446767400) ;Dragas, Marko (25027673300)Mitrovic, Mirjana (54972086700)Inferior vena cava (IVC) anomalies are uncommon congenital causes of deep vein thrombosis (DVT). KILT syndrome (kidney and IVC abnormalities with leg thrombosis) has only been described as case reports in the literature. Therefore, the characteristics, evaluation, and management of patients with KILT syndrome have not yet been standardized. This study aimed to systematically review and analyze the clinical and radiographic data and treatment of previously reported cases of KILT syndrome. In this systematic review, we performed a literature search of the PubMed, Scopus, and Web of Science databases in December 2023, with no restrictions on the publication date. After duplicate extractions, 4195 articles were screened. Case reports and case series reporting on KILT syndrome were included. In addition to previously published cases, we included a new case of a previously healthy 25-year-old man with KILT syndrome in the analysis. A total of 34 cases were therefore included in this study. The majority (76.5%) were male patients with a median age of 24 years. In most patients, unprovoked bilateral iliofemoral thrombosis was diagnosed, and 64.7% had left kidney abnormalities. Our study suggests that anomalies of the IVC should be suspected in all young patients, especially male patients, with proximal, recurrent, or idiopathic DVT. If an IVC anomaly is confirmed, the kidneys should be examined to monitor and preserve healthy kidneys in cases of KILT syndrome. The data collected from all patients emphasize the requirement of long-term anticoagulation and risk factor control. Surgical measures may be effective for treating symptomatic refractory cases. © The Author(s) 2024. - 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 Endovascular Treatment of Femoro-Popliteal Disease with the Supera Stent: A Single Center Experience(2025) ;Lukic, Borivoje (57189238643) ;Miletic, Marko (58509332500) ;Milosevic, Stefan (57214068151) ;Dragas, Marko (25027673300) ;Saponjski, Jovica (56629875900) ;Koncar, Igor (19337386500) ;Zlatanovic, Petar (57201473730) ;Lukic, Filip (57783469300) ;Mirkovic, Aleksandar (59676536600) ;Lazic, Dimitrije (59676721900) ;Markovic, Ksenija (57252972500) ;Milic, Natasa (7003460927)Cvetic, Vladimir (57189236266)Background/Objectives: Peripheral artery disease (PAD) is a significant global health challenge, affecting millions worldwide. Among its various manifestations, femoropopliteal atherosclerotic disease presents a unique challenge due to the biomechanical stresses on the superficial femoral artery (SFA) and popliteal artery (PA). Despite advancements in endovascular interventions, restenosis and stent fractures remain critical issues, particularly in complex and long lesions. Biomimetic stents, such as the SUPERA interwoven nitinol stent, have been developed to address these challenges by closely replicating the natural mechanical properties of the femoropopliteal arteries. This study evaluates the clinical and procedural outcomes of biomimetic stent implantation in patients with femoropopliteal atherosclerotic disease, focusing on patency rates, procedural success, and major adverse limb events (MALE). Methods: A cohort study was conducted at the University Clinical Center of Serbia, including 294 patients with femoropopliteal stenosis or occlusion treated with the SUPERA stent from January 2017 to December 2024. Patients were stratified by lesion complexity using the GLASS classification and procedural success, patency rates, and MALE incidence were assessed. Kaplan–Meier survival analysis was used to evaluate long-term outcomes, and Cox regression analysis identified predictors of MALE. Results: Primary patency rates at 1, 6, 12, and 24 months were 95.6%, 90.1%, 84.2%, and 77.7%, respectively. Primary-assisted patency and secondary patency rates remained high over time. Patients with GLASS IV lesions exhibited significantly lower patency rates and higher MALE incidence compared to GLASS I-III patients (p = 0.002). Occlusion length (≥16 cm) and lesion complexity (GLASS IV) were independent predictors of MALE (p = 0.015). The stent demonstrated high procedural success and durability, with minimal complications. Conclusions: Biomimetic SUPERA stents provide high patency rates and favorable clinical outcomes in complex femoropopliteal lesions. However, lesion complexity and occlusion length significantly impact long-term success. The findings highlight the importance of careful patient selection and lesion assessment for optimizing endovascular treatment strategies in PAD management. © 2025 by the authors. - 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 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
Publication Influence of perioperative risk factors on the development of transmural colonic ischemia after open repair of ruptured abdominal aortic aneurysm(2022) ;Ilic, Nikola (7006245465) ;Zlatanovic, Petar (57201473730) ;Koncar, Igor (19337386500) ;Dragas, Marko (25027673300) ;Mutavdzic, Perica (56321930600) ;Trailovic, Ranko (57006712200) ;Stevanovic, Ksenija (57376155800)Davidovic, Lazar (7006821504)BACKGROUND: Development of colonic ischemia (CI) after ruptured abdominal aortic aneurysm (RAAA) treatment is a lethal complication with perioperative mortality reported to be high as 50%. Therefore, the main goal of this study was to identify pre-, intra- and postoperative risk factors associated with CI in patients undergoing open repair (OR) due to RAAA, that might help to select patients who are more prone to develop CI. METHODS: This was a single-center prospective cohort study on patients with RAAA undergoing OR between January 1st 2018 and July 1st 2019, at the Clinic for Vascular and Endovascular Surgery, Clinical Center of Serbia. During this period 89 patients were treated due to RAAA and all were included in the study. The primary endpoint was grade III CI, or transmural necrosis, diagnosed by laparotomy. RESULTS: Out of 89 patients operated due to RAAA, CI was diagnosed in 14 (15.73%). During the operation, patients with CI had a longer duration of hypotension (42.86±35.82 vs. 24.13±23.48, P=0.021) and more common significant hypotension (54.54% vs. 14.66%, P=0.024). In the postoperative course, patients with CI had more common signs of abdominal compartment syndrome (71.42% vs. 25.33%, P=0.001) and higher mortality rate (78.57% vs 29.33%, P=0.001). The univariate regression model showed that one of the most significant factors that were associated with CI were age higher than 75 years, significant hypotension lasting more than one hour, organ lesion, development of abdominal compartment syndrome and higher potassium values on third and fourth quartile. CONCLUSIONS: Grade III colon ischemia (transmural) remains the important cause of mortality after ruptured abdominal aortic aneurysm repair. We identified pre- and intraoperative and postoperative risk factors that could improve the selection of patients for primary open abdomen treatment or early exploratory laparotomy in order to prevent or timely diagnose colon ischemia. © 2021 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 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

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 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

This condition is rarely associated with anomalous inferior vena cava (IVC). Polycystic horseshoe kidney is a very rare occurrence and however IVC anomalies common with polycistic disease are an increasingly recognized risk factor for iliofemoral deep venous thrombosis. Method: We present a case of 75-year-old patient with recurrent deep vein thrombosis (DVT) of right leg as a result of compression of large horseshoe kidney cysts in double inferior vena cava. Results: Large renal cyst were successful treated percutaneously punctured for the relief of compression and received injection of acidic solutions of 95% ethanol under ultrasound guidance for prevention against re-accumulation of cyst fluid. Conclusion: Percutaneous aspiration with ultrasound guidance with injection of sclerosing solutions as a relatively simple procedure and can be the method of choice for treatment of renal cysts. Also, any recurrent deep vein thrombosis on lower extremity requires additional evaluation in the form of an ultrasound or multidetector computed tomography examination of the abdomen. © The Author(s) 2022. - Some of the metrics are blocked by yourconsent settings

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.
