Type B dissection complicated with subacute visceral ischemia.

A 63-year old man presented with back pain and abdominal pain that worsened after eating. Contrast-enhanced computed tomography revealed type B aortic dissection. Arteriography 20 days after dissection revealed celiac trunk stenosis and the superior mesenteric artery did not arise from the true lumen. Saphenous vein bypass grafting from the right common iliac artery to the superior mesenteric and gastroduodenal arteries was performed. The postoperative course was uneventful and the abdominal symptoms completely disappeared.
