title: Obstruction of the superior mesenteric artery due to emboli from the thoracic aorta in a patient with thromboangiitis obliterans.
abstract: A 48-year-old woman presented at our hospital with acute abdominal pain 3 years after being diagnosed with thromboangiitis obliterans (TAO). Computed tomography revealed occlusion of the superior mesenteric artery (SMA) and multiple kidney infarction with thrombus floating in the thoracic aorta connected with the intercostal artery. Despite emergency embolectomy, further thromboembolism eventually required massive resection of the intestine with jejunostomy and colostomy and permanent intravenous hyper-alimentation therapy. Although TAO rarely involves the large artery, the aorta could be the source of embolization in patients with TAO.
