Successful reimplantation of the hypertrophied inferior mesenteric artery during an open abdominal aortic aneurysm repair.

Ischemic colitis is the most common form of an iatrogenic intestinal ischemia following an aortic surgery. It can be transient and self-limiting but, when severe, is associated with mortality even as high as 80%. Careful preoperative assessment can help to anticipate the need for the inferior mesenteric artery (IMA) reimplantation. Some patients lack the sufficient collateral blood supply to the colon and can benefit from the IMA reimplantation, which not only reduces the risk of postoperative colonic necrosis but also can be lifesaving. We report a case of a successful reimplantation of the IMA based on the careful preoperative planning. If unrecognized, this undoubtedly would lead to postoperative colonic ischemia. Therefore, we feel it is important to share our experience regarding the successful management of the presented case.
