Hybrid repair of thoracoabdominal aortic aneurysms involving the visceral vessels: comparative analysis between number of vessels reconstructed, conduit, and gender.

Background: Thoracoabdominal aortic aneurysm (TAAA) repairs are technically challenging. The advent of endovascular aneurysm repair in combination with visceral/renal artery bypasses has allowed for hybrid endovascular repair of these aneurysms. The purpose of this study was to evaluate whether outcomes were affected by the number of visceral/renal artery reconstructions, conduit, or gender.
