Hybrid techniques play a role in the treatment of patients who suffer from thoracoabdominal (TAAA) and pararenal aortic aneurysms (PAAA) but are unfit for open repair. The increasing number of TAAA patients treated by hybrid approaches has brought to light the severe procedure-related morbidity that can accompany these complex repairs. To overcome these issues, several techniques have been proposed to simplify them. This article reviews the most important technical advances of hybrid TAAA/PAAA repair, focusing on (1) the surgical approach, (2) the anastomotic technique for the renovisceral bypass, (3) antegrade versus retrograde renovisceral revascularization, and (4) simultaneous versus staged visceral hybrid repair. We discuss critical issues that may influence outcomes with these advanced procedures.

Double preloaded internal up-and-over technique for total transfemoral four vessel thoracoabdominal multibranch endoprosthesis with temporary aortic balloon occlusion for ruptured complex abdominal aortic aneurysm.

The thoracoabdominal multibranch endoprosthesis (TAMBE) is the first off-the-shelf, four-vessel branched endograft to obtain US Food and Drug Administration commercial approval for the treatment of complex abdominal and thoracoabdominal aortic aneurysms. Total transfemoral TAMBE approaches, previously described, may benefit patients with challenging aortic arch anatomy. This report presents a further refinement of the internal up-and-over total transfemoral TAMBE technique with temporary aortic balloon occlusion, applied in the setting of a ruptured pararenal abdominal aortic aneurysm.

Objective: To investigate outcomes obtained using an off the shelf pre-loaded inner branched endograft (E-nside) for the treatment of juxtarenal and pararenal aortic aneurysms (J-PRAA).
Methods: Data from a multicentre registry (INBREED), including patients treated with E-nside endograft, were prospectively collected and analysed. Patients treated for J-PRAA were included.

Introduction: The accuracy of fenestrations in stent grafts for complex aortic aneurysms and dissections can be significantly improved using three-dimensional (3D)-printed phantoms. Standardization is enhanced by using artificial intelligence (AI) for image pre-processing before 3D printing. These methods address fallacies in centerline image analysis and manual image pre-processing.

Objective: The aim of this study was to perform a comparative pre-clinical evaluation of a new fenestrated endovascular aneurysm repair dedicated stent using perfused 3D printed patient anatomies.
Methods: The test setup included a pulsatile pump set to reproduce human haemodynamics, four 3D printed pararenal aneurysms connected to a bench test, and four corresponding fenestrated grafts (Zenith Fenestrated; Cook, Bloomington, IN, USA). Bridging stents were sized based on analysis of patients computed tomography scans and included either four standard covered stents (BeGraft [BG]; Bentley, Hechingen, Germany) or four similar covered stent grafts mounted on a modified balloon to allow stent implantation and flaring in one step (BeFlared [BF]; Bentley).
Fenestrated Anaconda Endograft for the Treatment of Complex Aortic Aneurysms: Systematic Review and Meta-Analysis.

Purpose: To perform a systematic review and meta-analysis of the outcomes of Anaconda fenestrated endograft for the treatment of complex abdominal aortic aneurysms (cAAA).
Material And Methods: A systematic search of all the literature reported until May 2024 was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The pooled 30-day mortality rate, technical success rate, reintervention rate as well as bridging stent occlusion rate, and corresponding 95% confidence intervals (CIs) were estimated using fixed or random effect methods.
