Abstract

Isolated spontaneous dissection of the superior mesenteric artery is extremely rare. In December 2012, a 45-year-old man, without significant comorbidities, presented at the emergency room of another hospital with abdominal pain. The patient was treated with medical therapy and discharged on resolution of the pain. Three months later he returned to the emergency room with a new onset of pain. CT-angiography (CTA) showed an isolated SMA dissection associated with aneurysmal dilatation. The patient was referred to our attention. We attempted endovascular exclusion of the dissecting aneurysm in May 2013. We deployed a self-expandable nitinol stent (BostonSC Adapt 4-9×32 mm) in order to simultaneously repair the dissection, preserve the branches and exclude the aneurysm. Postoperative course was uneventful and the patient was discharged on postoperative day 2. At 10-month follow-up CTA showed excellent positioning of the stent, patency of the visceral branches and shrinkage of the aneurysm.
