A novel hybrid approach using antegrade visceral debranching from both axillary arteries for thoracoabdominal aneurysm repair

Abstract

Hybrid aortic surgery combining visceral debranching and stent grafting is an alternative to conventional open surgery and branched stent grafting for thoracoabdominal aneurysm repair. Visceral aortic branch bypasses are usually performed from the iliac arteries or the infrarenal or ascending aorta. Herein, we describe a new debranching technique to treat a painful Crawford type III thoracoabdominal aneurysm in a high-risk patient who was deemed unsuitable for open, endovascular, or traditional hybrid repair. The superior mesenteric artery and the right renal arteries were exposed via a right retroperitoneal approach and revascularized from the right axillary artery. Splenic and left renal arteries were exposed via a left retroperitoneal approach and revascularized from the left axillary artery.
