Revascularization of the Superior Mesenteric Artery in an Intestinal Angina / 日本心臓血管外科学会雑誌

ABSTRACT

A 69-year-old woman suffered from postprandial abdominal pain and hematochezia. Colonoscopy suggested ischemic colitis, and intestinal angina was diagnosed by multirow-detector computed tomography (CT), which showed occlusion of the superior mesenteric artery (SMA). On enhanced CT, there was extensive calcification on the aortic wall and aortic expansion and several mural thrombi in the thoracoabdominal and abdominal aorta, as well as severe stenoses in the bilateral common iliac arteries. A bypass from the right renal artery, which was the only artery without significant stenosis of the major branches of the abdominal artery, to the SMA, was created using a saphenous vein graft. Postoperatively, the postprandial abdominal pain disappeared, and the patient was discharged after a good postoperative course.
