One Case of Left External Iliac Artery–superior Mesenteric Artery Bypass for Superior Mesenteric Artery Occlusion

Abstract

An 85-year-old woman was introduced to our hospital due to her complain of abdominal pain after eating and bloody stool. We took contrasting CT and found superior mesenteric artery occlusion. We diagnosed intestinal ischemia. After following it up by fast, a symptom did not develop, but after starting a meal, abdominal pain developed again. After that, because the symptom was getting worse we decided to do an emergency surgery. We underwent left external iliac and superior mesenteric artery bypass using a prosthetic graft. Ischemic enterocolitis was prolonged after surgery, but there is not the appearance of abdominal pain. And one year passed after surgery, the graft performs patency. We underwent retrograde bypass using prosthetic graft, but the technique for the superior mesenteric artery occlusion has not been established. Because the state of a usable graft and the blood vessel of the central side varies according to a case, it is important to choice the technique depending on a case.
