[Treatment of acute type B aortic dissection with organ ischemia].

Nine patients, who suffered from acute type B aortic dissection with organ ischemia, were treated at our hospital from 2004 to 2006. Their mean age was 60.3 (range 37-73) years. Eight of them required surgical intervention. Two patients with mesenteric-ischemia underwent superior mesenteric artery (SMA) bypass surgery and their conditions were relieved. However, 1 of them died of aortic rupture 6 months later. One patient with celiac artery occlusion was at first treated nonsurgically, but was subjected to resection of the small intestine 3 weeks later because of ulcer perforation induced by ischemia. The other 5 patients with lower extremity ischemia underwent bypass surgery and were discharged. Bypass surgery is a reliable procedure for the treatment of acute type B aortic dissection with organ ischemia, allowing prompt resolution of ischemia.
