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.

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).

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).

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.

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.

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.

Evaluation of EndoAnchor Aortic Wall Penetration After Thoracic Endovascular Aortic Repair.

To analyze aortic wall penetration of Heli-FX EndoAnchors after use in seal zones in the aortic arch or descending thoracic aorta during thoracic endovascular aortic repair (TEVAR). From May 2014 to May 2019, 25 patients (mean age 70.5±10 years; 16 women) were treated with TEVAR and adjunctive use of the Heli-FX device in 3 academic vascular surgery departments.

Symptomatic Aortic Bare-Metal Stent Fracture after PETTICOAT Technique for Complicated Type B Aortic Dissection.

Background: Aortic bare-metal stent rupture is an exceptional complication, associated with high risk of aorta rupture and death. We describe a successful endovascular approach for a symptomatic aortic bare-metal stent fracture after the provisional extension to induce complete attachment (PETTICOAT) technique.

Methods: A 53-year-old man with a complicated type B aortic dissection (visceral malperfusion) was treated with thoracic endovascular aortic repair (TEVAR) and "PETTICOAT" technique.

Descending Aorta Rupture after Transcatheter Aortic Valve Embolization.

Background: To report a case of rupture of the descending aorta after aortic migration during transcatheter aortic valve replacement (TAVR).

Methods: An 85-year-old man with a severe and symptomatic aortic stenosis underwent elective TAVR, which complicated with embolization into the ascending aorta. While repositioning into the descending aorta, the procedure complicated with aortic rupture.

Conical neck is strongly associated with proximal failure in standard endovascular aneurysm repair.

Objective: Hostile proximal aortic neck (HN) challenges the suitability for standard endovascular aneurysm repair (EVAR) of patients at high risk for "open" repair. However, there has been little if any focus placed on the individual role of the "nonlength" HN features in EVAR outcomes. The aim of this study was to evaluate their individual and potentially predictive role in outcomes of EVAR under HN conditions.

Failed Minimally Invasive Staged Treatment of a Giant Symptomatic Aortic Perigraft Hygroma after Open Aortic Repair.

Background: Perigraft hygromas or seromas are an unusual finding and/or complication after open aortic repair.

Methods And Results: We present a case of an 82-year-old man with a previous urgent aortic bifurcated graft for abdominal aortic aneurysm rupture. He received several treatments due to abdominal compartment syndrome, requiring a Bogota Bag and colostomy derivation.

Anticoagulation Alone for Aortic Segment Treatment in Symptomatic Primary Aortic Mural Thrombus Patients.

Background: Primary aortic mural thrombus (AMT) is a rare entity. Asymptomatic AMT may be found in imaging studies for other disease studies. Symptomatic AMT as embolic events may localize in the arterial branches of the aorta; limb ischemia is the most usual clinical presentation, though.

Complementary Role of Fenestrated/Branched Endografting and the Chimney Technique in the Treatment of Pararenal Aneurysms After Open Abdominal Aortic Repair.

Purpose: To evaluate the totally endovascular techniques for treating complex pararenal aortic aneurysms after open repair of abdominal aortic aneurysm.
