Abstract
Primary abdominal aortic dissection occurs infrequently. We experienced aortic dissection originating at the level of the right renal artery, for which graft replacement and reconstruction of the aorta and also the celiac, superior mesenteric and both renal arteries were performed. A 44-year-old woman with severe back pain was admitted to our hospital. CT and aortogram revealed primary abdominal aortic dissection. The abdominal aorta was replaced with a trunk prosthetic graft, to which were connected smaller grafts for the four abdominal visceral and also lumbar arteries. The intercostal artery was preserved by a diagonal trasection at the upper end of the graft site. To prevent ischemia of the visceral organs, we used a selective perfusion technique to the superior mesenteric artery and both renal arteries. The postoperative course was uneventful. The postoperative aortogram demonstrated good patency and function of the trunk graft and reconstructed visceral arteries
