Purpose: To analyze sac evolution patterns in matched patients with hostile neck anatomy (HNA) treated with standard endovascular aneurysm repair (sEVAR) and endosutured aneurysm repair (ESAR).

Methods: Observational retrospective study using prospectively collected data between June 2010 and December 2019. ESAR group data were extracted from the primary arm of the PERU registry with an assigned identifier (NCT04100499) at 8 centers and those from the sEVAR came from 4 centers.

European Expert Opinion on Infrarenal Sealing Zone Definition and Management in Endovascular Aortic Repair Patients: A Delphi Consensus.

Purpose: The purpose of the study was to provide a consensus definition of the infrarenal sealing zone and develop an algorithm to determine when and if adjunctive procedure(s) or reintervention should be considered in managing patients undergoing endovascular aortic repair (EVAR) for infrarenal abdominal aortic aneurysm (AAA).

Methods: A European Advisory Board (AB), made up of 11 vascular surgeons with expertise in EVAR for AAA, was assembled to share their opinion regarding the definition of preoperative and postoperative infrarenal sealing zone. Information on their current clinical practice and level of agreement on proposed reintervention paths was used to develop an algorithm.

Materials And Methods: Retrospective analysis of patients undergoing endovascular treatment with the BeGraft aortic stent-graft in 8 European centers from January 2017 to October 2020. Demographics, perioperative data, and midterm outcomes were collected.

Endovascular aortic repair with EndoAnchors demonstrate good mid-term outcomes in physician-initiated multicenter analysis-The PERU registry.

Objectives: We aim to describe real-world outcomes from multicenter data about the efficacy of adjunct Heli-FX EndoAnchor usage in preventing or repairing failures during infrarenal endovascular aneurysm repair (EVAR), so-called EndoSutured-aneurysm-repair (ESAR).

Methods: The current study has been assigned an identifier (NCT04100499) at the US National Library of Medicine (https://ClinicalTrials.gov).

Innominate Artery Dissection Caused by Video-Mediastinoscopy.

Mediastinoscopy is considered a safe technique to biopsy mediastinal lesions. Among its complications, vascular ones are the most common. We present a rare case of intimal dissection of the innominate artery during the performance of a mediastinoscopy that caused an ischemic attack from which the patient recovered completely without long-term sequelae.

A multicenter "real-world" study of the valiant NAVION stent graft.

Background: The aim of the present study was to evaluate early results of thoracic endovascular aortic repair (TEVAR) using the Valiant Navion™ stent graft in a "real-world" scenario.

Methods: All patients who underwent TEVAR with the Valiant Navion™ endograft between November 2018 and November 2019 were included in this retrospective multicenter study (six European centers). The primary endpoints were technical success, incidence of major adverse events (MAEs), access failure, deployment failure, deployment accuracy, and rate of intraoperative endoleaks (ELs).

Preoperative Planning for EndoAnchor Use During Thoracic Endovascular Aortic Repair in the Distal Aortic Arch.

Purpose: To describe steps related to intraoperative C-arm orientations that can be taken during preoperative planning of thoracic stent-graft repair to facilitate the deployment of EndoAnchors in the distal aortic arch.

Technique: Previous experience from transcatheter aortic valve implantation (TAVI) may be helpful in addressing issues with C-arm orientation. In TAVI, preoperative computed tomography (CT) images are routinely obtained to generate a patient-specific curve that represents a virtually complete rotation of the C-arm perpendicular to the annulus.

Systematic Review on the Use of Physician-Modified Endografts for the Treatment of Aortic Arch Diseases.

Background: The total endovascular approach is in current evolution, and many series have described variable outcomes for branched technology, chimney techniques, or fenestrated repair; and even a combination of some of them. We aim to describe the current outcomes on physician-modified endograft for the treatment of arch diseases.

Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used for this systematic review.

Pelvic radiation therapy as a potential risk factor for ischemic colitis complicating abdominal aortic reconstruction.

A 78-year-old man with a 56-mm juxtarenal aneurysm and previous pelvic radiotherapy for prostate cancer (3 years earlier) who was disease free during follow-up received elective aortoaortic bypass suprarenal clamping through a transperitoneal approach. After the patient experienced initial abdominal pain and diarrhea, a computed tomography scan showed mild sigmoid inflammation, and the patient received conservative treatment. One month after discharge, the patient underwent urgent laparotomy and bowel and sigmoid resection for an enterocutaneous fistula.

The Potential Relation Between polytetrafluoroethylene Grafts after Open Reconstructions for Abdominal Aortic Aneurysm and Perigraft Seromas.

Background: The presence of sac enlargement after abdominal aortic aneurysm (AAA) open repair, a condition usually called perigraft seroma (PGS), nearly always has a benign behavior. Some theories implicated for PGS formation include coagulation abnormalities, fibroblast inhibition, low-grade infection, or improper graft handling.

Methods: This is a retrospective study including patients treated for AAA in 2 academic vascular surgery departments from 2007 to 2014, where 1 center preferably used polytetrafluoroethylene (PTFE) grafts whereas the preference of other center was mostly Dacron graft.

Predictors of inadequate EndoAnchors aortic wall penetration for the Endosutured therapy in hostile neck patients.

Background: The use of EndoAnchors is increasing; however, not much about appropriate use in terms of aortic wall penetration (AWP) is described. We aim to evaluate the procedural and anatomical conditions related with borderline (b) or absence (ab) of AWP when checked on first CT-scan after the Endosutured aortic repair (ESAR) for hostile neck anatomies (HNA).

Methods: This study with NCT04100499 is a single center prospective evaluation of patients receiving EndoAnchors for prevention or treatment of a proximal EVAR failure.

Adapting Vascular Surgery Practice to the Current COVID-19 Era at a Tertiary Academic Center in Madrid.

Background: The epidemic potential of coronavirus infection is now a reality. Since the first case detected in late 2019 in China, a fast worldwide expansion confirms it. The vascular patient is at a higher risk of developing a severe form of the disease because of its nature associating several comorbid states, and thus, some vascular surgery communities from many countries have tried to stratify patients into those requiring care during these uncertain times.

Improved Midterm Outcomes Using Standard Devices and EndoAnchors for Endovascular Repair of Abdominal Aortic Aneurysms with Hyperangulated Necks.

Purpose: Loss of fixation and seal represent a key problem when undertaking endovascular repair of abdominal aortic aneurysms (AAA) with hyperangulated necks (HAN). This study assesses the outcomes following the use of adjunct endostapling to supplement proximal aorto-prosthetic fixation in patients who have AAAs with HAN.

Methods: A retrospective review of a prospective database of 42 patients with HAN (> 60°) who underwent endovascular aneurysm repair (EVAR) with supplementary endostapling was undertaken.
