[Revascularization of the inferior mesenteric artery through an endoaortic approach. A prospective series of 51 cases].

From January 1, 1986 to December 31, 1987, 170 subrenal abdominal aortic aneurysms were operated on using a technique involving systematic revascularisation of the inferior mesenteric artery each time this was possible. The electively chosen revascularisation method was endo-aortic reimplantation which was carried out on 51 occasions out of 53 revascularisations. The post-operative mortality was zero. Post-operative angiographic examination via the arterial route was systematically performed. 5 post-operative occlusions occurred. In these patients undergoing inferior mesenteric revascularisation, there was only one single case of severe ischemic colitis which subsequently resolved. Endo-aortic reimplantation of the inferior mesenteric artery would thus appear to be the procedure of choice for the prevention of ischemic colitis when the ostium is not stenosed or occluded.
