In-Stent Restenosis after Carotid Artery Stent Placement Comparing Maximum Plaque Predilation and Postdilation.

Purpose: To compare the incidence of in-stent restenosis (ISR) and ipsilateral neurologic symptoms in patients treated with maximum plaque dilation before stent deployment (max-pre-D) and stent placement followed by angioplasty (post-D) technical variants of carotid artery stent placement at midterm follow-up.

Materials And Methods: This was a single-center, real-world, retrospective comparative study of 307 patients treated in a single vascular surgery unit between 2014 and 2018. The follow-up protocol consisted of Doppler US performed at 1, 6, and 12 months and annually thereafter.

Endoleak outcomes with different stent-graft generations in a 25-years thoracic endovascular aortic repair experience.

Introduction: To compare endoleak outcomes after thoracic endovascular aneurysm repair (TEVAR) with different stent-graft generations into long-term follow-up.

Design: retrospective, observational, and single-center cohort study.

Methods: TEVAR procedures performed between November 1995 and December 2020 were analyzed.

Intravascular Ultrasound in Branched and Fenestrated Endovascular Aneurysm Repair: Initial Experience in a Single-Center Cohort Study.

Purpose: To evaluate intravascular ultrasound (IVUS) safety and efficacy to detect visceral stenting issues during complex endovascular aneurysm repair through branched and fenestrated repair (B-FEVAR).

Materials And Methods: A single-center retrospective analysis of 33 bridging stents assessed intraoperatively using IVUS between January and September 2020 was performed. Ten aortic aneurysm patients [7 thoracoabdominal / 1 pararenal / 2 juxtarenal; 3 females; mean age 73 years [range 70-77 years]) were included.

A prognostic risk score for major amputation in dialysis patients with chronic limb-threatening ischemia after endovascular revascularization.

Background: Almost 38% of all patients with end-stage chronic kidney disease (CKD) have peripheral arterial disease of the lower limbs that can lead to chronic limb threatening ischemia (CLTI). The aim of this study was to assess the impact of several factors to conduct a stratification of the amputation risk in CKD patients with CLTI receiving endovascular revascularization.

Methods: Observational, retrospective, single-center study of patients treated from 2010 to 2016.

Outcome of Endovascular Repair of Popliteal Artery Aneurysms using the Supera Stent.

Purpose: To evaluate the efficacy of endovascular repair of popliteal artery aneurysms (PAAs) with a wire-interwoven nitinol stent.

Materials And Methods: This is a prospective, descriptive, and analytical study. From January 2016 to December 2018, 28 consecutive patients (29 lower limbs) were treated for a PAA with the deployment of the Supera stent (Abbott Vascular, Illinois).

Impact of plaque dilation before carotid artery stent deployment.

Objective: Plaque stability is of utmost importance for stroke prevention in the perioperative period (within 24 hours) following carotid artery stenting (CAS). Although carotid plaque is entrapped between stent struts after stent deployment, postdilation can cause a scissoring effect on the plaque, increasing the risk of postprocedural embolic events due to plaque prolapse. Maximum carotid plaque dilation before stent deployment may reduce this risk.

Influence of Type of Fixation and Other Characteristics on Outcome after Endovascular Repair of Ruptured Abdominal Aortic Aneurysms.

Background: Endovascular treatment nowadays represents a valuable option in the treatment of ruptured abdominal aortic aneurysms (rAAAs). The aim of this study is to evaluate a 15-year, single-center experience with endovascular treatment of rAAAs and the role of the type of fixation in outcome.

Methods: Retrospective analysis of all consecutive hemodynamically stable and unstable patients with a diagnosed rAAA treated at this hospital with an endovascular procedure between December 1999 and January 2015 was conducted.

New Conception of Relining in the Endovascular Aneurysm Sealing Era: A Monocentric Case Series Study.

Over 20 years from the first endovascular aortic repair, endoleaks still represent a common problem, even with newer endograft generation. Numerous procedures can be adopted to manage these complications; relining of the endoprosthesis is a rational technique to treat type III and IV endoleaks. The absence of dedicated materials for these procedures forces the vascular surgeon to perform complex hybrid or endovascular interventions.

Endovascular aneurysm sealing with the Nellix endograft in hemodynamically-unstable ruptured abdominal aortic aneurysm with challenging anatomy.

Background: To assess immediate and midterm outcomes of hemodynamically-unstable patients with ruptured abdominal aortic aneurysm (rAAA) treated with the Nellix endovascular sealing system (EVAS).

Methods: From June 2014 to June 2017, 21 hemodynamically-unstable rAAA patients with challenging anatomies were treated with EVAS. The mean AAA diameter and neck length measured 73±15 mm and 14±10 mm, respectively.

Midterm Outcomes of the Nellix Endovascular Aneurysm Sealing System: A Dual-Center Experience.

Purpose: To report midterm outcomes of the Nellix Endovascular Aneurysm Sealing (EVAS) System in the treatment of abdominal aortic aneurysm (AAA).

Methods: Between September 2013 and July 2014, 64 AAA patients (mean age 76.6±6.

Use of Aortic Occluders and Endovascular Plugs in a 2-step Hybrid Treatment of Secondary Aortoenteric Fistulas.

Aortoenteric fistula (AEF) is a dreadful complication of abdominal aortic surgery. Surgical treatment is associated to high mortality and requires urgent graft removal with extra-anatomic or in situ reconstruction. Other authors suggest the use of stent grafts, both as a stand-alone procedure or as a bridge solution before open repair.

Durability and efficacy of tibial arterial stent placement for critical limb ischemia.

Purpose: To analyze the efficacy and durability of long-term tibioperoneal arterial stent placement for selected cases of symptomatic chronic limb ischemia (CLI).

Materials And Methods: From January 2005 to June 2012, 168 limbs (155 patients) were treated with percutaneous transluminal angioplasty (PTA)/stent placement for de novo tibial stenosis or occlusion in at least one tibial artery. Most patients (92.

Midterm results of endovascular treatment of superficial femoral artery disease with biodegradable stents: single-center experience.

Purpose: To assess the midterm efficacy of a biodegradable poly-l-lactic acid (PLLA) stent in the treatment of superficial femoral artery (SFA) occlusive disease.

Materials And Methods: Between June 2009 and April 2011, 35 de novo SFA lesions were treated with 43 biodegradable stents. This nonrandomized, retrospective, single-center study included patients with moderate or severe claudication, lower-limb rest pain, or ischemic ulceration restricted to the toes; symptoms were classified as Rutherford category 2 (48.

Mechanical thrombectomy in proximal subclavian artery in-stent occlusion.

Purpose: Mechanical thrombectomy is an established tool for endovascular therapy of acute/chronic in-stent occlusions of the lower extremities, especially for the superficial femoral artery. The authors report the use of the Rotarex catheter system for an in-stent proximal subclavian occlusion.

Case Presentation: A 51-year-old female patient with previous multiple attempts at left subclavian revascularization; primary endovascular stenting at the origin of the subclavian artery occluded at 3 months, and a carotid-subclavian bypass was placed distally to the stent.
