title: Spontaneous dissection of the superior mesenteric artery as a rare cause of acute abdomen: report of two cases.
abstract: Spontaneous dissection of the superior mesenteric artery (SMA) is a rare condition. Here we report 2 cases of spontaneous SMA dissection causing acute abdomen. Bowel infarction did not occur in either case despite total occlusion or severe stenosis of the SMA;we successfully managed isolated SMA dissection without surgical intervention. Our nonoperative management regimen for spontaneous SMA dissection consisted of intestinal rest with fasting, administration of a vasodilator, and blood pressure control. Surgical intervention should be unnecessary unless complications, such as intestinal infarction and abdominal angina, occur.
