Spontaneous Isolated Superior Mesenteric Artery Dissection (SISMAD)
A Case Report and Review of the Literature
Keywords:

Introduction: Spontaneous isolated superior mesenteric artery dissection (SISMAD) is a rare vascular disease that lacks evidence-based guidelines regarding treatment options. In this paper, we present a case report perform a literature review of potential methods for the treatment of SISMAD.
Materials and Methods: A 60-year-old man presented with epigastric pain that had been aggravated by the consumption of food for two weeks. There was no history of smoking or alcohol consumption, and he had received previous treatment for hypertension and thyrotoxicosis which had lasted for over five years. After the detection of SISMAD, he was treated conservatively with antiplatelets for a follow up period of over 18 months. After this period of treatment, he no longer presented symptoms and there was a regression of the lesion which was demonstrated by interval CTA and duplex US.
Conclusion: Conservative treatment can sometimes be used for SISMAD in selected cases. Further investigations when bowel ischemia or mesenteric hemorrhage is suspected might be necessary as invasive treatment might be indicated.
