Two Case of Spontaneous Isolated Dissection of the Superior Mesenteric Artery

Abstract

Spontaneous isolated dissection of the superior mesenteric artery (SMA) is rare, especially when not associated with aortic dissection. The standard therapeutic strategy is either a surgical approach, which is the most frequently adopted in cases with abdominal symptoms, or medical treatment in asymptomatic cases. In this report we present 2 cases of spontaneous isolated dissection of the SMA treated medically and which resulted in the disappearance of a pseudolumen. Asymptomatic isolated SMA dissection can be treated medically, and computed tomography was very useful in the present cases.
