Introduction: Prevention of peri- and postprocedural complications is still a challenge in carotid artery stenting (CAS).

Aim: To assess immediate and long-term safety and effectiveness of CAS using the Roadsaver double-nitinol-layer-micromesh stent.

Material And Methods: Since 2014, 298 CAS procedures in 287 non-consecutive patients (203 men, mean age 70.

Introduction: Radial or brachial access may be preferred in the case of severe peripheral artery disease (PAD) or difficult aortic arch anatomy during carotid artery stenting (CAS).

Aim: To evaluate the clinical conditions indicating potential benefit from non-femoral access as well as feasibility and safety of transradial/transbrachial access (TRA/TBA) as an alternative approach for CAS.

Material And Methods: Since 2013, 67 patients (mean age: 70 years old, 44 men, 42% symptomatic) were selected for CAS with the TRA/TBA approach.

Introduction: Constant technological progress in the field of carotid stenting translates into improved short- and long-term results of endovascular treatment. The introduction of a new generation, self-expanding, open-cell stent has provided a new treatment option in endovascular management of carotid stenosis.

Aim: To evaluate 30-day and 1-year clinical outcomes of non-consecutive patients with high risk of carotid endarterectomy, who underwent 5F cylinder-tapered MER™ open-cell carotid stent implantation.

Introduction: Drug-eluting stents of the first (DES I) and second generation (DES II) proved superior to bare metal stents (BMS) in the coronary territory. However, there are limited data on whether they have any advantage over BMS in vertebral artery stenosis (VAS).

Aim: To compare outcomes of DES (DES I, DES II) and BMS in the treatment of symptomatic extracranial VAS.

Introduction: A relationship between carotid stenosis and coronary arterial disease (CAD) is widely accepted; however, data on the exact prevalence of coronary disease in patients with severe carotid stenosis are lacking. Information on the prevalence and predictors of CAD among these patients could impact diagnostic and treatment approaches.

Aim: The primary aim of this study was to determine the prevalence of significant CAD among patients referred for carotid artery revascularization.

Introduction: Vertebrobasilar territory ischemia leads to disabling neurological symptoms and may be caused both by vertebral artery (VA) and subclavian artery (SA) stenosis. The coexisting symptomatic ipsilateral VA and proximal SA stenosis should be considered as a true bifurcation lesion for percutaneous treatment.

Aim: To evaluate the safety and efficacy of simultaneous angioplasty of vertebral and subclavian stenosis.

Introduction: Prevention of periprocedural stroke has a crucial role in carotid artery stenting (CAS) procedures.

Aim: To assess retrospectively 30-day safety and effectiveness of 41 procedures of internal and common carotid artery stenting using the Roadsaver double nitinol layer micromesh stent in 40 non-consecutive patients with symptomatic or high-risk carotid artery stenosis.

Material And Methods: The patients were men ( = 31) and women ( = 9); mean age was 67.

Introductuion: Symptomatic severe vertebral artery (VA) stenosis may be treated safely with stent supported angioplasty via femoral access. There is limited clinical data on transradial approach for VA angioplasty in case of peripheral artery disease.

Aim: To evaluate the safety and efficacy of transradial angioplasty of symptomatic VA stenosis.

Article presents a case of a 71-year old woman with pulmonary right upper venous drainage into the superior vena cava and with coexistence sinus venous type Atrial Septal Defect (ASD) which was revealed as interesting finding in multislices computed tomography angiography during estimation of coronary arteries.

Objectives: To assess safety and efficacy of carotid artery stenting (CAS) according to "tailored-CAS" algorithm in the elderly (≥75 years) in relation to younger patients.

Background: Although CAS has grown as an alternative to carotid endarterectomy the data on safety of CAS in the very elderly are inconsistent.

Material And Methods: 1,139 patients with significant carotid stenosis underwent 1,252 CAS procedures in one high-volume center between years 2001-2011.
