Abstract
We report a case of superior mesenteric artery (SMA) dissection which was treated conservatively without anticoagulation or antiplatelet agents. We also review 33 cases of isolated SMA dissection treated conservatively, reported in Japan from August, 2008 to April, 2011 (including the present case). There were no cases which required surgical revascularization. In the anticoagulation group, there were 5 cases with a persistent false lumen and 2 cases with recurrence of a false lumen. In the antiplatelet group, there were no cases of false lumen recurrence.
