Objective: This study aimed to clarify the selection and determination of appropriate treatment for acute symptomatic spontaneous isolated dissection of the superior mesenteric artery (SIDSMA). Methods: Data from 10 consecutive patients, who were diagnosed with symptomatic SIDSMA using computed tomography angiography and were managed in our hospital from January 2010 to October 2015, were retrospectively collected and analyzed. Results: There were nine males and one female; mean patient age was 50.3 (range, 35-64) years. All patients experienced acute abdominal pain, and three patients experienced concomitant vomiting. Only one patient exhibited symptoms of suspected peritonitis and intestinal ischemia. Three patients showed improved abdominal pain before admission to our hospital. One patient experienced severe abdominal pain that could not be managed using morphine; he underwent right external iliac to superior mesenteric artery bypass with a great saphenous vein graft. No patient presented with intestinal necrosis. All patients survived, and no patient developed complications during the follow-up period of up to 42 (24.5±16.5) months. Conclusion: Conservative management appears to be the most feasible treatment for SIDSMA. However, open surgery can be performed in patients presenting with any symptoms of intestinal ischemia.
