Short and Long Term Outcome of the Symptomatic Isolated Superior Mesenteric Artery Dissection after Conservative Treatment

Abstract

The criteria of the second intervention for the superior mesenteric artery dissection (SMAD) after conservative treatment generally include persistent symptoms, bowel ischemia, diameter enlargement, progression of the dissection and so on. However, the criteria have not been elucidated. Among them, our criteria include only bowel ischemia and diameter enlargement. We reviewed the short- and long-term outcomes of the 26 patients of SMAD after conservative treatment. There were no patients who had a secondary intervention, and the prognosis was favorable.
