Impact of Previous Thoracotomy on Outcomes of Open Thoracoabdominal Aortic Aneurysm Repair: A Retrospective Propensity Score-Matched Analysis.

ABSTRACT: Objectives: Open repair remains widely used for TAAA (Thoracoabdominal Aortic Aneurysm), but disease progression may require reoperation via repeat thoracotomy, which is technically challenging. These procedures involve increased risks due to adhesions and altered anatomy. This study aims to evaluate the impact of repeat thoracotomy on early surgical outcomes in TAAA patients. Methods: We conducted a retrospective cohort study of 214 patients who underwent open TAAA repair between June 1996 and March 2023. Among them, 30 underwent repeat thoracotomy (RT), and 184 underwent their first thoracotomy (FT). To reduce baseline discrepancies, propensity score matching (3:1) was performed, resulting in 22 RT patients matched with 45 FT patients. The primary outcome was 30-day mortali
