Successful Endovascular Covered-stent Treatment of Ulcer-like Projection (ULP) after the Superior Mesenteric Artery Dissection

Abstract

A 52-year-old man had a sudden onset of stomach ache and back pain. Computed tomography (CT) scan showed a dissociation of the celiac artery and the superior mesenteric artery (SMA). The dissection of the SMA was Type III of the Sakamoto classification. We started conservative treatment, but the stomach ache persisted. There were mild expansion of ulcer-like projection (ULP) and the stenosis of the SMA distal side in CT scan of the tenth day. We conducted covered-stent placement without being able to deny the intestinal ischemia. The stent performed probe patency, and ULP was thrombosed, and stenosis of the SMA was improved by the CT scan of the third month after treatment.
