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.

Introduction Endovascular treatment of chronic total occlusion (CTO) represents a true challenge even for experienced interventional radiologists. We are presenting a case of hidden antegrade dissection of the external iliac artery (EIA) after a failed attempt to recanalize CTO of the common femoral artery (CFA). Case outline A 52-year-old male patient was admitted for multidetector computed tomography (CT) angiography. Left common iliac artery (CIA) stenting was performed, followed by “crossover” attempt of recanalization of right CFA CTO that failed. The next day, left femoral superficial artery angioplasty was performed and after one month, angioplasty of the left popliteal and the bellow-knee arteries. A month later, the patient was readmitted for surgical reconstruction of the CFA. After desobstruction, excellent inflow was obtained and a Dacron graft was inserted. A few hours postoperatively, Fogarty catheter thrombectomy was performed. The next morning, pulsations were weakened again and CT angiography showed antegrade dissection of the EIA. Stenting of the EIA was performed with two stents and a favorable outcome was achieved. After a detailed analysis of the CT, hidden thrombosed antegrade dissection of the EIA was noted in the lateral view, which was not seen in the posterior/anterior view and was presented as fibrous plaque with mural thrombosis. Dissection occurred after failed attempt of CFA recanalization and was clinically silent until flow was established triggering opening of the false lumen and the release of thrombotic masses. Conclusion In patients with failed angioplasty of CTO of the CFA and CT characteristics of fibrous plaque proximal to the site of attempted angioplasty, thrombosed antegrade dissection should be considered. © 2022, Serbia Medical Society.

Background Eagle syndrome represents elongated styloid process characterized by calcification and ossification of the stylohyoid ligament rarely associated with the pathology of carotid arteries. We are presenting a very rare case of bilateral Eagle syndrome with associated internal carotid artery (ICA) kinking on the right side and significant ICA stenosis on the left side. Case Report A 62-year-old female patient was admitted to our Institution for multidetector computed tomography (MDCT) angiography. Two years ago, she experienced stroke with right-sided weakness, color Doppler scan of carotid arteries described left ICA stenosis of 75% and right ICA stenosis of 50%. MDCT arteriography revealed bilateral Eagle syndrome associated with significant left ICA stenosis of >90% and right ICA kinking. Left carotid endarterectomy was performed followed by elongated styloid process resection that was in close relationship to ICA. Even more significant relationship was seen on the right side involving right ICA kinking and elongated styloid process that was treated conservatively. Postoperative course was uneventful; after 6 months, the patient was doing well. Conclusions This is the first case that describes bilateral Eagle syndrome associated with ICA kinking on one side and significant stenosis on the other. Although rare, this syndrome should be thought of in symptomatic patients with carotid pathologies in which case computed tomography angiography is of crucial importance. © 2016 Elsevier Inc.

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.

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.

Introduction: Ischemic postconditioning (IPCT) represents one of the several therapeutic strategies to attenuate ischemic reperfusion injury (IR) after carotid endarterectomy (CEA). We here present the first in-human study of IPCT in carotid surgery. Methods: The study represents an observational case-control study, with the data collected in our Institution carotid database. From December 2015 to December 2020, a total of 300 patients were included in our study; IPCT group consisted of 148 patients in whom ischemic postconditioning was performed while control group consisted of 152 patients in whom IPCT was not performed. Indications for IPCT technique were: severe unilateral internal carotid artery (ICA) stenosis (>90%), severe bilateral ICA stenosis (>80%), severe ICA stenosis (>80%) with contralateral ICA occlusion and ICA subocclusion. IPCT was performed by applying 6 cycles of 30 sec reperfusion (declamping of ICA)/30 sec ischemia (clamping of ICA) after finishing the procedure and initial declamping. Two groups of patients were compared in terms of occurrence of intrahospital and early postoperative stroke, TIA (transient ischemic attack) and neurologic morbidity. Results: Cumulative incidence of intrahospital postoperative stroke or TIA was significantly higher in the control group (5.3% vs 0.7%, P =.036). According to carotid plaque characteristics, patients in the IPCT group had significantly more frequent presence of heterogenous plaque, as well as ulcerated plaque, which was associated with the absence of postoperative stroke and significantly lower cumulative rate of TIA/stroke when compared to the control group (43.9% vs 8% and 47.3% vs 1.5%). During the follow-up period of 1 month after the surgery, there were no cases of stroke, TIA and deaths due to neurological causes in both groups of patients. Conclusion: Our results showed that IPCT significantly reduced the incidence of postoperative cerebral ischemic complications after CEA in high-risk patients for IR injury when compared to the control group. © The Author(s) 2022.

More than 50 years ago, vitamin K antagonists were the only available oral anticoagulants. Since their application involves a number of limitations, it was necessary to develop new oral anticoagulant drugs and introduce them into clinical practice. These drugs have many advantages over vitamin K antagonists, including rapid onset/offset, a small number of interactions with other drugs and food, simplified dosing and predictable pharmacokinetics, eliminating the need for daily laboratory monitoring. In addition, new oral anticoagulant drugs act selectively on a single coagulation factor. Currently, the following drugs are approved for use: direct thrombin inhibitor, dabigatran etexilate, direct factor Xa inhibitor, rivaroxaban, apixaban and edoxaban. Dabigatran etexilate and apixaban are approved for the primary prevention of venous thromboembolism in adult patients undergoing elective surgery of total hip or knee replacement, while in addition to these anticoagulants edoxaban is approved for the prevention of stroke and systemic embolism in adult patients with non-valvular atrial fibrillation. For the treatment and prevention of recurrent deep vein thrombosis dabigatran etexilate, rivaroxaban and edoxaban are approved. In addition, rivaroxaban is approved for the secondary prevention of atherothrombotic events in patients with acute coronary syndrome. © 2017, Serbian Medical Society. All rights reserved.

Introduction Although intervention in patients with symptomatic carotid disease is generally accepted as beneficial, the management of asymptomatic disease is still controversial. We wanted to introduce and discuss treatment options in a patient with asymptomatic carotid stenosis and high embolic potential lesions of common and internal carotid artery detected by multidetector computed tomography (MDCT). Case Outline A 78-year-old female patient was admitted to our institution for diagnostics and surgical treatment of asymptomatic high-grade carotid stenosis. Upon admission, color duplex ultrasonography of the carotid arteries revealed the left common carotid artery (CCA) stenosis of 50% and the ipsilateral internal carotid artery (ICA) stenosis of 60%, while the right CCA was narrowed by 60% and the ipsilateral ICA by 80%. Because of the left subclavian artery (LSA) occlusion, also described by ultrasonography, MDCT angiography was performed to assess arterial morphology for possible angioplasty. In addition to LSA occlusion, MDCT angiography surprisingly revealed significant left CCA (>80%) and ICA (>70%) narrowing by ulcerated plaques with high embolic potential. Surgical treatment of the left CCA and ICA was indicated and DacronR tubular graft interposition was performed. The postoperative course was uneventful and the patient was discharged from the Institute on the third postoperative day. After the six-month follow-up the patient was doing well with well-preserved graft patency. Conclusion Although color duplex ultrasonography is reliable and safe imaging modality in carotid stenosis diagnosis, MDCT angiography plays a significant role in patients with asymptomatic carotid stenosis since plaques with high embolic potential could be detected, which, if left untreated, could have severe neurological ischemic consequences. © 2015 Serbia Medical Society.

Introduction Infection of synthetic graft in the groin is a rare but devastating complication. When it occurs, several possibilities of treatment are available. Extra-anatomic reconstruction and in-situ implantation of new, infection resistant grafts are associated with high mortality and morbidity. Therefore, more conservative approach is needed in some cases. Negative-pressure wound therapy is one of the options in treating such patients. Objective The aim of this study was to assess the outcome for deep groin vascular graft infection treated with negative-pressure wound therapy. Methods Seventeen patients (19 wounds), treated for Szilagyi grade III groin infections between October 2011 and June 2014, were enrolled into this observational study. Results Majority of the wounds (11/19) were healed by secondary intention, and the rest of the wounds (8/19) were healed by primary intention after initial negative-pressure wound therapy and graft substitution with silver-coated prostheses or autologous artery/vein implantation. No early mortality was observed. Minor bleeding was observed in one patient. Reinfection was noted in three wounds. Only one graft occlusion was noted. Late mortality was observed in three patients. Conclusion Negative-pressure wound therapy seems to be safe for groin vascular graft infections and comfortable for both patient and surgeon. However, the rate of persistent infection is high. This technique, in our opinion, can be used as a “bridge” from initial wound debridement to definitive wound management, when good local conditions are achieved for graft substitution, either with new synthetic graft with antimicrobial properties or autologous artery/vein. In selected cases of deep groin infections it can be used as the only therapeutic approach in wound treatment. ©2016, Serbia Medical Society. All rights reserved.

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

Having in mind the influence of lipid profile in initiation and development of atherosclerosis, we examined the concentration of total cholesterol, triglycerides, low density lipoproteins and high density lipoproteins in the serum from rabbits with experimental atherosclerosis induced by a hypercholesterolemic diet (4% solution of crystalline cholesterol in edible oil). For this study three groups of rabbits were used: a control group fed on the standard diet for this species (n=7), control group fed on an oil-containing diet (n=7) and experimental group fed on a hypercholesterolemic diet (n=7). After two months of treatment we examined the serum concentration of lipids by using enzymatic colorimetric method. Experimental atherosclerosis was confirmed pathohistologically. The levels of concentration of total cholesterol and low density lipoproteins were highly significantly increased (p<0.01) in the sera of the investigated groups compared to the control group. In comparison with the control group the concentration of triglycerides was highly significantly decreased (p<0.01) in the serum of investigated groups. The level of high density lipoproteins was significantly decreased in the serum of the investigated groups compared to the control group, as well as in the serum of experimental group fed on a hypercholesterolemic diet compared to the control group fed on an oil-containing diet (p<0.05 respectively). Our findings indicate that lipid profile has an important role in the pathogenesis of experimental atherosclerosis.

Introduction Splenic artery aneurysm (SAA) represents the third cause of abdominal aneurysms, just after abdominal aorta and iliac arteries aneurysms, with overall prevalence of 1%. Pancreatitis has been linked with pseudoaneurysm formation of SA due to destruction of arterial wall by pancreatic enzymes, however true SAA associated with pancreatitis has not been described yet. We are presenting the first case of true SAA in a patient with chronic pancreatitis and primary biliary cholangitis successfully treated by surgical excision, direct arterial reconstruction and spleen preservation. Case outline A 74-year-old male patient was admitted for multidetector computed tomography angiography due to suspected SAA and renal artery aneurysm (RAA). He was previously treated for chronic pancreatitis and primary biliary cholangitis. Upon admission, computed tomography arteriography showed SAA 32 mm in diameter and RAA 12 mm with SAA being in direct contact with superior margin of the pancreas. Surgical treatment of SAA was indicated while RAA was treated conservatively. Intraoperatively, SAA adherent to the superior margin of pancreas was noted, followed by complete exclusion of the aneurysm and end-to-end splenic artery anastomosis. Histopathology showed atherosclerotic degeneration of arterial wall with all three layers presenting as true aneurysm. Two years after the surgery, control computed tomography angiography showed regular postoperative findings without further progression of RAA. Conclusion This is the first case to describe a true SAA aneurysm originated on the field of previous episodes of chronic pancreatitis and primary biliary cholangitis. Surgical treatment including aneurysm resection and direct arterial reconstruction with spleen preservation showed satisfactory results. © 2021, Serbia Medical Society. All rights reserved.

Colic artery aneurysms (CAA) are among the rarest visceral artery aneurysms that carry a significant risk of rupture with a high mortality rate. Concomitant occlusive disease of the mesenteric arteries can significantly alter the type of treatment undertaken (open or endovascular). We present the case of a 68-year-old woman with a visceral artery aneurysm that was discovered coincidently during a routine ultrasound examination. The patient reported no abdominal or back pain or any symptoms associated with mesenteric ischemia. Computed tomography angiography showed a near total occlusion of the celiac trunk, segmental complete occlusion of the superior mesenteric artery, and a middle colic artery (MCA) aneurysm measuring 22 mm in diameter. Complete resection of the MCA aneurysm was performed, with subsequent reconstruction by end-to-end anastomosis. There is no clear evidence to support indications for intervention according to aneurysm size in asymptomatic patients with CAA. Endovascular occlusion of the proximal and distal arterial segments is often considered a first-line approach, which was inappropriate in our case. Open surgical reconstruction was mandatory to preserve collateral circulation and avoid bowel ischemia in circumstances of occlusive mesenteric artery disease. We decided not to treat the stenotic lesions of the mesenteric arteries, given the absence of mesenteric ischemia symptoms. © Indian Association of Cardiovascular-Thoracic Surgeons 2025.

Introduction: Carotid angioplasty and internal carotid artery stenting is the therapeutic method of choice in the treatment of carotid restenosis, but when it is not technically feasible (expressed tortuosity of supraaortic branches, calcifications, presence of pathological elongation of very long lesions) a redo surgery is indicated. Objective: The aim of our study was to examine the benefits and risks of redo surgery in patients with symptomatic and asymptomatic significant internal carotid artery restenosis and its impact on early and late morbidity and mortality. Methods: The study included 45 patients who were surgically treated for a hemodynamically significant internal carotid artery restenosis from January 2000 to December 2009. Surgical techniques included redo endarterectomy with direct suture, redo anderectomy with a patch plastic and resection with Dacron tubular graft interposition.The patients were followed for postoperative neurological ischemic events (transient ischemic attack (TIA), stroke), local surgical complications and lethal outcome after one month, six months, one year and after two years). Results: In the early postoperative period (up to 30 days) there were no lethal outcomes. TIA was diagnosed in four patients (8.8%), minor stroke in one patient (2.2%) and one patient (2.2%) also had cranial nerve injury. After two years two patients died (4.4%) due to fatal myocardial infarction, three patients (6.5%) had ipsilateral stroke and one patient developed graft occlusion (2%). Conclusion: In the case of symptomatic and asymptomatic: carotid restenosis that cannot be treated by carotid percutaneous angioplasty, redo surgical treatment is therapeutic option with an acceptable rate of early and late postoperative complications.

This is a case report of a 63-year-old man who presented with a pseudoaneurysm of the left common carotid artery following a previous neck injury. The pseudoaneurysm was discovered incidentally during a routine Doppler ultrasound of the neck after the patient suffered a stroke with right-sided hemiparesis and dysphasia. A multi-detector computed tomography angiography scan showed a 25-mm pseudoaneurysm with a partial thrombus in the lumen, originating from the left common carotid artery. The patient underwent open surgery with reconstruction done by the interposition of a prosthetic graft between the common and internal carotid arteries. The postoperative course was uneventful, and the patient was discharged on the third postoperative day. The rarity of extracranial carotid artery pseudoaneurysms and their potential to cause serious complications such as stroke and rupture underscores the need for prompt diagnosis and management. The question of the best treatment remains controversial, and there are no studies that directly compare the success of open surgery and endovascular treatment of extracranial carotid artery pseudoaneurysm. Regular ultrasound monitoring should be performed in patients with confirmed neck trauma and/or operations to detect any delayed onset of carotid pseudoaneurysms. © Association of Surgeons of India 2023.

The aim of this article is to review our experience in surgical treatment of carotid atherosclerosis using eversion carotid endarterectomy (ECEA) in 5,034 patients, with particular attention to temporal changes in patients' characteristics, diagnostic approach, surgical technique, medical therapy, and outcome in the early (group A, 1991-1997) versus fate (group B 1998-2004) period of ECEA. 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.

Introduction Acute lower limb ischemia results from thrombosis or embolization of diseased native artery or previously implanted bypass graft. When this occurs, several options are available to restore blood flow: catheter-directed thrombolysis, mechanical thrombectomy or open surgery. Fundamental reasons to apply percutaneous interventions are avoiding open procedures in high risk patients, and avoiding difficult dissection through scar tissue. Case Outline A 67-year-old male was admitted at our Institution for critical limb ischemia. After performed angiography the diagnosis of occluded femoropopliteal graft was established. Occlusion was resolved by catheter-directed thrombolysis with plasmin. Culprit lesions were treated by angioplasty. Conclusion Our patient underwent a successful thrombolysis of occluded femoropopliteal graft with locally-delivered human plasmin. © 2014, Serbia Medical Society. All rights reserved.
