The remarkable advances in technology and devices in the last two decades have made possible the endovascular repair of complex abdominal (cAAA) and thoracoabdominal (TAAA) aortic aneurysms with challenging anatomy. To date, despite the creation of multiple fenestrated/branched endografts intended to treat these difficult cases, in the USA, many of them remain available only under physician sponsored investigational device exemption (PSIDE) protocols in few institutions. The Gore Thoracoabdominal Branched Endoprosthesis (TAMBE; W.L. Gore & Associates, Flagstaff, AZ, USA) investigational device is a four-branched off-the-shelf (OTS) endograft that concluded an early feasibility study in 2016 and is currently finalizing a pivotal trial in pursuit of approval from the Food and Drug Administration. This article discusses the TAMBE early feasibility multicenter study results, the most relevant features of this device, its anatomical feasibility, and the impressions about this endograft as an OTS option for the treatment of CAAA and TAAA.

Background: We have developed a model aimed at identifying preoperative predictors of operative mortality in patients who undergo elective, open thoracoabdominal aortic aneurysm (TAAA) repair. We converted this model into an intuitive nomogram to aid preoperative counseling.
Methods: We retrospectively analyzed data from 2884 elective, open TAAA repairs performed between 1986 and 2023 in a single practice.

Background: Cerebrospinal fluid (CSF) drainage is used to reduce spinal cord ischemia (SCI) in patients undergoing thoracoabdominal aortic procedures. Recent literature has found high rates of complication associated with CSF drainage, which has led to changes in practice. The aim of this study was to investigate rates of CSF drain-related complications in patients undergoing a thoracoabdominal aortic procedure with perioperative placement of a CSF drain.

Degeneration of the thoracoabdominal aorta proximal to a prior fenestrated endovascular aortic repair represents a complex issue with limited options for repair. Previously, modified endografts or open conversion with endograft explant offered the only options for management. Here we describe use of the Gore Thoracoabdominal Multibranch Endoprosthesis for exclusion of an extent III thoracoabdominal aneurysm in the setting of degeneration proximal to a previously placed fenestrated device.

Article Synopsis
- * The study looked at 40 CTD patients who had TEVAR for thoracoabdominal aortic aneurysms or aortic dissections between February 2014 and April 2021, revealing most had previous aortic interventions and a significant number faced complications post-surgery.
- * Results showed a high reintervention rate (62.5%), with reinterventions typically occurring within the first year, and indicated ongoing risks for aortic-related issues, highlighting challenges in treating CTD patients
Target Artery Outcomes Following Endovascular versus Open Surgical Repair of Thoracoabdominal Aortic Aneurysms - A Single Center Comparative Study.

Objective: To compare target artery (TA) outcomes after fenestrated or branched endovascular aortic repair (FB-EVAR) versus open surgical repair (OSR) of thoracoabdominal aortic aneurysms (TAAAs).
Background: Few studies have compared TA outcomes after endovascular incorporation and open reconstruction.
Methods: Among consecutive patients who underwent elective OSR or FB-EVAR of TAAAs (2008-2020), we reviewed those who had postoperative imaging studies evaluating TA.
