Isolated Superior Mesenteric Artery Dissection: A Case Report and Literature Review



Isolated Superior Mesenteric Artery Dissection: A Case Report and Literature Review



Gastroenterology Research 11(5): 374-378



Spontaneous isolated superior mesenteric artery dissection (ISMAD) is an uncommon cause of abdominal pain. Clinical presentation ranges from an asymptomatic incidental finding to acute bowel ischemia or fatal aneurysmal super mesenteric artery (SMA) rupture. We report the case of a 58-year-old male presenting with abdominal pain. Imaging studies revealed an ISMAD without radiological evidence of bowel ischemia. The patient was successfully treated using a conservative approach including bowel rest and anticoagulation. ISMAD incidence is expected to increase with the utilization of advanced imaging modalities. Thus, an ISMAD should be suspected when other common causes of an acute abdomen have been excluded. Given the lack of evidence-based guidelines, management options include conservative treatment and anticoagulation, endovascular stenting, or open surgical repair.
