A Modified Technique of Intercostal Artery Implantation for Thoracoabdominal Aortic Aneurysm Using the Tube of the Aortic Wall

Abstract

We report a modified intercostal artery implantation using the tube of the aortic wall alternative to the Crawford inclusion and Carrel Patch techniques for thoracoabdominal aortic aneurysm repair. Intercostal and lumbar arteries were isolated within a full-thickness excised aortic cuff and tailored into a tube. An 8-mm limb was sewn to the proximal graft and the aortic cuff tube. The distal tube end was sewn to an 8-mm limb and a distal limb was connected to the distal graft. Computed tomography (CT) showed no pseudoaneurysms or aneurysmal expansion but did show patent intercostal arteries at the implantation site more than 5 years later.
