Isolated superior mesenteric artery dissection

Discussion:

Isolated dissection of the main trunk of the superior mesenteric artery (SMA) without aortic involvement is an unusual condition and the involvement of the intestinal blood supply is a major cause of death.

Sometimes this condition may resolve spontaneously, but usually, when dissection of SMA occurs, the mortality rate is high. Therefore, it is important to make an early diagnosis.
