Case Series on Double-Barrel Stenting for the Renal Arteries Associated With Fenestrated Repair (FEVAR) of Complex Anatomy Aortic Aneurysms.

The double-barrel stenting (DBS) is a technique in which 2 parallel stents are simultaneously deployed through the same reinforced fenestration, into 2 adjacent target vessels. Prior reports describe the application of this technique for the treatment of superior mesenteric artery dissection with aneurysmal degeneration, coronary artery bifurcations, aortic arch branches, and intracranial aneurysms. The DBS technique is particularly useful in the context of fenestrated repair (FEVAR) of complex anatomy aortic aneurysms when the origin of visceral arteries branch off the aorta very close to each other or present early branches.

Rare Case of Abdominal Aortic and Multiple Visceral Aneurysms in a Pediatric Patient With PIK3CA Mutation and Vasculitis.

Abdominal aortic aneurysms (AAA) are most commonly observed in elderly male patients and are particularly rare in children. Among the pediatric population, they are usually diagnosed in the context of connective tissue disorders, genetic mutations, or vasculitis. The same is true of visceral arteries aneurysms.

Mid-term Renal and Mesenteric Artery Outcomes During Fenestrated and Branched Endovascular Aortic Repair for Complex Abdominal and Thoracoabdominal Aortic Aneurysms in the United States Aortic Research Consortium.

Objective: To report mid-term outcomes of renal-mesenteric target arteries (TAs) after fenestrated-branched endovascular aortic repair (FB-EVAR) of complex abdominal and thoracoabdominal aortic aneurysm.

Background: TA instability (TAI) is the most frequent indication for reintervention after FB-EVAR.

Methods: Data from consecutive patients enrolled in 9 prospective nonrandomized physician-sponsored investigational device exemption studies between 2005 and 2020 were reviewed.

Outcome Analysis Comparing Asymptomatic Juxtarenal Aortic Aneurysms Treated with Custom-Manufactured Fenestrated-Branched Devices and the "Off-The-Shelf" Zenith p-Branch Device.

Background: Numerous endovascular options have been used for the repair of juxtarenal aortic aneurysms (JRAAs) over the last 15 years. This study aims to compare the performance between the Zenith p-branch device and custom-manufactured fenestrated-branched devices (CMD) for the treatment of asymptomatic JRAA.

Methods: A single-center retrospective analysis of prospectively collected data was performed.

Novel Application of Branched Endograft for Preservation of Pelvic Circulation.

Background: Endovascular repair of a proximal anastomotic pseudoaneurysm (APSA) of an end-to-side aortobifemoral bypass (ABF) can lead to pelvic ischemia. We present a novel application of branched aortic endograft to repair such pseudoaneurysm while preserving flow into the ABF and native aortoiliac system.

Methods: A 71-year-old male with history of aortoiliac occlusive disease resulting in lifestyle limiting claudication was treated with an aortobifemoral bypass in 1999.
