Stent implantation for mesenteric bypass graft stenosis

Purpose: To present a case of symptomatic mesenteric bypass graft stenosis treated with Palmaz stent implantation. Methods and Results: A 65-year-old man with a history of mesenteric ischemi a and superior mesenteric artery (SMA) occlusion presented with recurrent s ymptoms 3 years after Dacron graft revision surgery for occlusion of a veno us aorto-SMA bypass graft. Graft thrombectomy revealed a tortuous segment o f narrowed graft proximally, and a Palmaz stent was deployed across the def ect. Adequate flow was restored through the conduit, and the patient has re mained asymptomatic for 2 years. Conclusions: Mesenteric ischemia is a rare and potentially fatal condition requiring major vascular intervention. Revision surgery may be avoided by a ngioplasty and stent insertion across flow-limiting stenoses, even in prost hetic grafts.
