Acute Type A aortic dissection with superior mesenteric arterial dissection; report of a case

We report a case of acute type A dissection with acute abdomen due to blood flow insufficiency in the superior mesenteric artery. A 73-year-old man was presented to hospital complaining sudden onset of chest pain. Contrast-enhanced computed tomography revealed a type A aortic dissection, that extended from the ascending aorta to the left common iliac atery. Superior mesenteric artery was compressed by the thrombosed false lumen. Epigastric pain was exacerbated acutely, we decided to treat the bowel ischemia 1st, and after that, if bowel ischemia was reversible, central repair operation performed. Emergent saphenous vein bypass was performed from the right external iliac artery to the superior mesenteric artery. Then total arch replacement was performed using cardiopulmonary bypass. The patient complicated with postoperative paralytic ileus, he completely recovered without bowel resection.
