It has been reported that prognosis for acute intestinal ischemia because of acute occlusion of the superior mesenteric artery (SMA) has a pessimistic outcome. Forty-one patients with occlusion of SMA have been surgically treated in the six-year period between 1986 and 1992 at the Department of General Surgery. Chang Gung Memorial Hospital. There were 24 males and 17 females whose ages ranged from 34 to 85 years. The overall mortality rate was 56% (thrombosis vs embolism=52%; 62.5%). The clinical features showed no difference between patients with thrombosis of SMA and patients with embolism of SMA, except that the embolism group were prone to be febrile. Patients with sudden onset of abdominal pain associated with either valvular heart disease or atrial fibrillation strongly suggest SMA occlusion. However, some patients showed no specific findings suggesting SMA occlusion, which made the diagnosis difficult. Most of the patients with SMA occlusion received resection of the bowels. Vascular procedures were tried, with success in only one case. Only abnormal chest X-ray film and incorrect initial diagnosis predict a worse prognosis after analysis of various risk factors.
