Purpose: There are still limited data to determine the efficacy of interwoven nitinol stent (INS) compared with laser-cut nitinol stent (CNS) for the endovascular treatment of long femoropopliteal lesions. The aim of this study is to evaluate the short- and mid-term results of the effectiveness of CNS and INS in the revascularization of long femoropopliteal occlusions. We performed analyses of the primary and secondary outcome measures for subgroups of patients with below-the-knee and "above-the-knee" lesions.

Background: The purpose of this study was to compare femoropopliteal bypass (FPB) and remote endarterectomy (RE) for long femoropopliteal lesions.

Methods: Single center retrospective propensity matching analysis of the symptomatic patients with long occlusion of the femoro-popliteal segment (>250 mm), who underwent femoro-popliteal bypass above the knee or remote endarterectomy from 2014 to 2020. Primary endpoints: primary patency (PP), secondary patency (SP), target lesion revascularization (TLR).

Background: Careful selection of patients for carotid stenting is necessary. We suggest that patients with a shaggy aorta syndrome may be at higher risk for perioperative embolic complications.

Methods: The study is a retrospective subanalysis of the SIBERIA Trial.

Purpose: The efficacy and safety of the Supera stent in superficial femoral artery (SFA) have been reported mostly in shorter lesions with relatively low proportion of occlusions. There are little data on the effectiveness of the Supera stent in long lesions. The aim of this study was to assess the clinical safety and efficiency of the Supera stent in the treatment of long femoropopliteal occlusive lesions (Trans-Atlantic Inter-Society Consensus [TASC] C/D) in patients with symptomatic peripheral artery disease.

Background: Fasciotomy can increase the mobility of the superficial femoral artery and decrease the incidence of stent fractures. This study aimed to compare the long-term patency of drug-eluting nitinol stents with and without fasciotomy in patients with prolonged superficial femoral artery occlusions.

Methods: A randomized clinical trial was conducted in 60 (1:1) patients with long femoropopliteal steno-occlusive lesions >200 mm.

Objective: The objective of this randomized study was to compare the short- and long-term safety and efficacy of endovascular recanalization with stenting (EI) and remote endarterectomy (RE) for patients with superficial femoral artery (SFA) total occlusive lesions (≥250 mm).

Methods: Between July 2013 and July 2017, eligible patients with SFA total occlusive lesions were randomized to EI or RE. The EI group underwent recanalization and stenting of long SFA atherosclerotic occlusive lesions.

Objectives: The aim of this study was to compare procedure-related ipsilateral cerebral embolism with a conventional (Acculink, Abbott Vascular) versus a MicroNet-covered (CGuard, InspireMD) stent in carotid artery stenting (CAS).

Background: The MicroNet-covered stent may reduce periprocedural cerebral embolism in CAS, but level 1 evidence is lacking.

Methods: A total of 100 consecutive patients were randomized 1:1 to filter-protected CAS using the Acculink or the CGuard device.

Introduction: Concurrent stenting of complex iliac lesions during infrainguinal bypasses can increase the complexity of a case and impact outcomes.

Objective: Our aim was to evaluate the effect of inflow stenting of TASC-II C, D iliac lesions on femoropopliteal bypass patency.

Methods: A retrospective observational cohort study of patients who underwent femoropopliteal bypass with TASC-II C, D iliac artery stenting (hybrid group) or without inflow lesions (non-hybrid group) was conducted.

Unlabelled: The objective of the study was to describe immediate and long-term results of carotid endarterectomy (CEA) versus carotid stenting (CAS) with embolic protection in patients with severe carotid artery stenosis in clinical practice.

Materials And Methods: This is a retrospective cohort study, conducted between 2009 and 2017. During the analyzed period, 2132 operations (2006 patients) were performed: 1215 (57%) CEA and 917 (43%) CAS.

The objective is to evaluate the frequency of primary obstruction events (PrO) during one-year follow-up after performing excisional atherectomy with the SilverHawk/TurboHawk atherectomy device (S/TH) or remote superficial femoral artery endarterectomy (RSFAE) in patients with the chronic superficial femoral artery occlusive disease (СSFAOD). We included all randomized clinical trials (RCTs) and not-RCTs concerning the treatment of patients with СSFAOD after S/TH and RSFAE without duration. Twenty-nine items (1990-2017) were discovered; 27 articles on the levels of evidence were included in qualitative synthesis; 9 studies (meta-analysis) were included in quantitative synthesis.

Background: The objectives of our research were to identify whether the new method of carotid endarterectomy (CEA) with autoarterial remodeling of bifurcation of the common carotid artery (ARBCCA) influences daily parameters of blood pressure and heart rate (HR) while monitoring them on a daily basis and to assess the efficacy of the suggested method.

Materials And Methods: It is a prospective randomized comparative study. The first group (n = 100) included patients that underwent ARBCCA, the second group (n = 100) included patients that underwent "classic" CEA with xenopericardial patch closure.

Background: Superficial femoral artery (SFA) remote endarterectomy offers the advantage of preserving anatomy and geometry of the native artery, but the risk of restenosis still exists. The particular role of the adductor canal (AC) in mechanical constraints has been highlighted. The aim of this study was to assess if a surgical protocol associating remote SFA endarterectomy and AC freeing would modify the SFA geometrical changes during physiological limb flexion.

Objective is to compare the predictive value of stump pressure (SP) and cerebral oximetry (rSO2) levels in the evaluation of ischaemic injury of the cerebrum during clamping of the carotid artery (CCA) without temporary shunt (TS). Methods We included 84 patients with an asymptomatic stenosis (>70%) of the internal carotid artery (ICA) who underwent carotid endarterectomy (CEA) under GA. Cerebral ischaemic tolerance (CIT) was determined on the basis of SP, rSO2 and ∆rSO2 (↓rSO2 from baseline) during CCA.

Background: The aim of study was to estimate the safety and efficacy of using laser wavelength of 1560 nm with the foam sclerotherapy (FS) of varicose veins (VVs) for the treatment of severe primary chronic venous insufficiency (CVI, C4-C6) in patients with different diameters of the proximal segment (DPS) of the great saphenous vein (GSV).

Methods: We have separated the patients into two groups depending on the size of GSV: group 1 (281 cases; DPS of GSV less than 15 mm) and group 2 (210 cases; DPS of GSV more than 15 mm). Both groups received the endovenous laser ablation (EVLA) of the saphenous vein trunk, incompetent perforator veins (IPs) and FS (Tessari method) of VVs.
