Indications, safety, and effectiveness of transcatheter electrosurgical septotomy during endovascular repair of aortic dissections.

Objective: Endovascular repair of aortic dissections may be complicated by inadequate sealing zones, persistent false lumen perfusion, and limited space for catheter manipulation and target artery incorporation. The aim of this study was to describe the indications, technical success, and early outcomes of transcatheter electrosurgical septotomy (TES) during endovascular repair of aortic dissections.

Methods: We reviewed the clinical data of consecutive patients treated by endovascular repair of aortic dissections with adjunctive TES in two centers between 2021 and 2023.

Aneurysm sac shrinkage at 1 year after fenestrated-branched endovascular aortic repair of complex aortic aneurysms offers mid-term survival advantage.

Objectives: To investigate the impact of 1-year changes in aneurysm sac diameter on patient survival after fenestrated-branched endovascular aortic repair (FB-EVAR) of complex abdominal aortic aneurysms or thoracoabdominal aortic aneurysms.

Methods: We reviewed the clinical data of patients enrolled in a prospective nonrandomized study investigating FB-EVAR (2013-2022). Patients with sequential follow up computed tomography scans at baseline and 6 to 18 months after FB-EVAR were included in the analysis.

Transcatheter electrosurgical septotomy technique for chronic postdissection aortic aneurysms.

Aortic dissection often results in chronic aneurysmal degeneration due to progressive false lumen expansion. Thoracic endovascular aortic repair and other techniques of vessel incorporation such as fenestrated-branched or parallel grafts have been increasingly used to treat chronic postdissection aneurysms. True lumen compression or a vessel origin from the false lumen can present considerable technical challenges.

Prospective evaluation of upper extremity access and total transfemoral approach during fenestrated and branched endovascular repair.

Objective: Total transfemoral (TF) access has been increasingly used during fenestrated-branched endovascular aortic repair (FB-EVAR). However, it is unclear whether the potential decrease in the risk of cerebrovascular events is offset by increased procedural difficulties and other complications. The aim of this study was to compare outcomes of FB-EVAR using a TF vs upper extremity (UE) approach for target artery incorporation.

How We Would Treat Our Own Thoracoabdominal Aortic Aneurysm.

This manuscript is intended to provide a comprehensive review of the current state of knowledge on endovascular repair of thoracoabdominal aortic aneurysms (TAAAs). The management of these complex aneurysms requires an interdisciplinary and patient-specific approach in high-volume centers. An index case is used to discuss the diagnosis and treatment of a patient undergoing fenestrated-branched endovascular aneurysm repair for a TAAA.

Changes in renal-mesenteric duplex ultrasound velocities after fenestrated and branched endovascular aortic aneurysm repair.

Objective: Stenting of renal and mesenteric vessels may result in changes in velocity measurements due to arterial compliance, potentially giving rise to confusion about the presence of stenosis during follow-up. The aim of our study was to compare preoperative and postoperative changes in peak systolic velocity (PSV, cm/s) after placement of the celiac axis (CA), superior mesenteric artery (SMA) and renal artery (RAs) bridging stent grafts during fenestrated-branched endovascular aortic repair (FB-EVAR) for treatment of complex abdominal aortic aneurysms (AAA) and thoracoabdominal aortic aneurysms.

Methods: Patients were enrolled in a prospective, nonrandomized single-center study to evaluate FB-EVAR for treatment of complex AAA and thoracoabdominal aortic aneurysms between 2013 and 2020.
