[Revascularization technics of the inferior mesenteric artery]

Recanalization of the inferior mesenteric artery is the only way to prevent with certainty the risk of post-operative ischaemia of the colon. Two different techniques can be used: either reimplantation by the intra-aortic route if the inferior mesenteric artery is healthy, or PTEF bypass rather than direct reimplantation in case of ostial or near-ostial stenosis. The feasibility of these procedures has been confirmed by angiographic controls. No case of gangrene requiring excision of the colon has been observed post-operatively, and only one case of regressive ischaemic colitis has been recorded after recanalization.
