title: Mesenteric revascularization in a contaminated abdomen: a case report.
abstract: The management of acute mesenteric ischemia in the contaminated abdomen may require the use of an autogenous graft to achieve mesenteric revascularization. The authors present a case of an ischemic small bowel perforation in a 62-year-old-woman whose preoperative angiogram demonstrated occlusion of the celiac, superior mesenteric, and inferior mesenteric arteries. Vein mapping of the right greater saphenous vein demonstrated a dual saphenous system whose individual diameters were more than 4 millimeters. Exploratory laparotomy revealed a diffusely ischemic small bowel and liver, as well as abdominal sepsis from the perforated small bowel. Revascularization was accomplished by using saphenous vein in a nonreversed orientation as a bifurcated conduit from the supraceliac aorta to the hepatic and superior mesenteric arteries. Following revascularization, the liver and small bowel immediately regained a normal perfused appearance and the perforated segment of small bowel was resected and reanastomosed. She returned for a follow-up clinic visit 5 months later and was found to have an asymptomatic 6 cm aneurysm involving the proximal mesenteric vein bypass. The aneurysmal aspect of the vein bypass was replaced with a polytetrafluoroethylene interposition graft originating from the supraceliac aorta. On follow-up 3 months later, her aortomesenteric bypass is patent without aneurysmal recurrence, and she is clinically asymptomatic from any symptoms of mesenteric ischemia.
