    Abstract:
    Spontaneous isolated superior mesenteric artery dissection (SISMAD) is a rare cause of acute abdominal pain, but could potentially be fatal to patients, and should be recognized soon in the emergency department after excluding other common causes. Computed tomography (CT) is the modality of choice for initial diagnosis and follow-up. Currently there is no evidence-based guidelines for managing SISMAD. A 58-year-old man being suspected of a mesenteric artery dissection was referred to our emergergy department. The patient was monitored, treated conservatively with anticoagulant and discharged after 3 days. Follow-up CT scans at 6 month, 1 year and 1 year and a half post discharge showed a partially occluded false lumen, the diameter of true lumen had increased in size and no signs of bowel ischemia. SISMAD should be considered as part of differential diagnoses when patients in their fifth to seventh decades of life present with acute abdominal pain. Treatment includes conservative management, percutaneous endovascular interventions, or surgery, but most patients can be managed conservatively.
