A Stent Graft Placement in a Focally Progressed Dissection in the Superior Mesenteric Artery

ABSTRACT

Focal aneurysmal change after spontaneous superior mesenteric artery (SMA) dissection has been reported rarely. A stent graft implantation can exclude false lumen and possibly make major abdominal operation avoidable. A 52-year-old male patient was admitted due to abdominal pain for 10 days. A CT scan showed severe narrowing of the true lumen of SMA, approximately a 7 cm segment from the origin, due to compression by the thrombosed false lumen. Five days after admission, abdominal pain aggravated progressively. The follow-up CT revealed focal aneurysmal dilatation of the dissected SMA segment. I report here an endovascular treatment with stent graft implantation for a focal aneurysmal change after SMA dissection.
