Abstract
We describe a technique for repairing Crawford type IV thoracoabdominal aortic aneurysms using a midline abdominal incision with left transverse extension, performed in the supine position without thoracotomy. Six patients (median age, 73 years) underwent this approach for true aneurysms, chronic dissection, or aortoduodenal fistula. Aortic reconstruction was performed with four-branched or bifurcated grafts under selective visceral perfusion. All patients were discharged home; one required reoperation for bleeding, and one developed an abdominal wall incisional hernia. This approach provided sufficient exposure for proximal and distal anastomoses and facilitated concurrent abdominal procedures while minimizing respiratory complications.
