Endovascular repair of intercostal and visceral aortic patch aneurysms following open thoracoabdominal aortic aneurysm repair

Academic Article

Abstract

  • Purpose: Reoperative open surgical repair (OSR) of thoracoabdominal aortic aneurysms (TAAAs) is associated with high morbidity and mortality. The aim of this study was to analyze outcomes of fenestrated–branched endovascular aneurysm repair (F-BEVAR) for the treatment of intercostal or visceral aortic patch aneurysms after OSR of TAAAs. Methods: We reviewed the clinical data and outcomes of consecutive patients treated at 8 academic centers by F-BEVAR for visceral and intercostal aortic patch aneurysms after OSR of TAAAs (2011-2019). All patients had involvement of at least one target vessel requiring incorporation by a fenestration or directional branch. End points were technical success, 30-day and/in-hospital mortality, major adverse events, patient survival, target vessel patency/instability, and freedom from reintervention. Results: There were 29 patients with a median age of 70 (interquartile range, 63-74) years. Seven patients (24%) had connective tissue disorders. Technical success was 100%. There were no 30-day/in-hospital mortalities. Major adverse events occurred in 5 patients (17%), including estimated blood loss >1 L in 3 patients (10%), acute kidney injury and respiratory failure in 2 patients (7%) each, and transient paraparesis in 1 patient (3%). Median follow-up was 14 (interquartile range, 7-37) months. At 2 years, primary and secondary patency, freedom from target artery instability, freedom from reintervention, and patient survival were 95%, 100%, 83%, 61%, and 96%, respectively. Conclusions: F-BEVAR could be considered as an alternative to reoperative OSR in patients with visceral or intercostal aortic patch aneurysms. This series showed no mortality and a low rate of major adverse events, but a significant need for reintervention.
