Thoracoabdominal aneurysm repair using a four-branched thoracoabdominal graft: a case series

Revascularization of the visceral arteries during thoracoabdominal aneurysm repair is usually performed sequentially by an anastomosis between a prosthetic graft and an aortic patch. There are immediate operative risks such as bleeding and distortion. In the longer term, aneurysm, pseudo-aneurysm and rupture may occur. These require reoperation and are associated with significant morbidity and mortality.We present our experience with Crawford IV thoracoabdominal aneurysm repair in four patients, using a prefabricated four-branched graft (Coselli graft). At two years there were no deaths, no complications and no vessel abnormalities on computed tomography. We recommend its use as the graft of choice in young patients with an aortic tissue disorder requiring total resection of the aortic wall at the level of the visceral vessels.
