Abstract Previous attempts at repair of aortic dissection complicated by intestinal infarction requiring concomitant bowel resection have been fatal. Presented is a case of distal aortic dissection resulting in colonic infarction and perforation. Thoracoabdominal aortic fenestration with concomitant right hemicolectomy was successful. In patients with aortic dissection complicated by mesenteric ischemia, we recommend urgent graft replacement of the thoracoabdominal aorta when feasible. When peritoneal contamination precludes the use of prosthetic grafts, thoracoabdominal fenestration is an effective option.
