    Journal: Surg Today; 2004; 34(8):658-61. PubMed ID: 15290394.
    Abstract:
    PURPOSE: Several methods of revascularization after mesenteric ischemia have been proposed. Using a new route, we performed retrograde loop bypass grafting to the superior mesenteric artery (SMA) with a ringed expanded polytetrafluoroethylene (ePTFE) graft. METHODS: We anastomosed the graft to the infrarenal aorta, which ran behind the left renal hilum, turned ventral, and was anastomosed to the SMA in an antegrade fashion hemodynamically. Five patients underwent this procedure, which resulted in remarkable symptomatic relief. RESULTS: There were no postoperative deaths or serious complications, although some patients suffered paralytic ileus. All of the grafts remained patent during long-term follow-up, ranging from 17 to 72 months (mean: 37.8 months). Postoperative angiograms showed good configuration of the graft, which did not compress the renal vessels. CONCLUSION: Infrarenal aorta-SMA bypass relieved mesenteric ischemia and achieved good long-term graft patency. Thus, we consider it to be an effective and durable vascular procedure to reduce postoperative mortality and morbidity.
