Reimplantation of a Stenotic Inferior Mesenteric Artery for Chronic Visceral Artery Occlusion after Failed Bypass to the Superior Mesenteric Artery

摘要

The patient was a 71-year-old man complaining of postprandial abdominal pain and weight loss. Computed tomography angiography showed occlusion of the superior mesenteric artery and the celiac axis. The inferior mesenteric artery, supplying the mesenteric circulation, was stenotic at its origin. The patient had portal vein thrombosis and was diagnosed as having antiphospholipid antibody syndrome. The reimplantation of the inferior mesenteric artery was successfully performed after failed bypass grafting to the superior mesenteric artery from the abdominal aorta.
