Endovascular management for isolated spontaneous dissection of the superior mesenteric artery: report of two cases and literature review.

The clinical course and treatment strategies of isolated superior mesenteric artery (SMA) dissection have not been fully investigated. Two cases of uncontrolled abdominal pain caused by isolated SMA dissection were successfully treated with percutaneous endovascular stent placement. At follow-up 6 months later, computed tomography confirmed that the lesions had stabilized. The patients remained symptom free at 14- and 13-month follow-up, respectively. The present report describes these two cases of isolated SMA dissection treated successfully with percutaneous endovascular stent placement, along with a review of the related literature.
