One-stage repair of a thoracoabdominal aortic aneurysm associated with infrarenal aortic occlusion and visceral artery stenosis using a modification of the standard atriofemoral bypass technique - A case report

Thoracoabdominal aortic aneurysms (TAAA) are associated infrequently with v isceral artery occlusive disease and rarely with aortoiliac occlusion. The presence of occlusion of the infrarenal abdominal aorta limits the options for visceral artery perfusion and spinal cord protection by means of distal aortic perfusion and, consequently, increases the risk for postoperative c omplications and mortality. Significant stenoses of the visceral arteries f urther add to the complexity of the repair. We describe a one-stage repair of a type I TAAA associated with infrarenal aortic occlusion and significan t stenoses of all visceral arteries using a modified distal perfusion techn ique.
