title: Successful angiographic stent-graft treatment for spontaneously dissecting broad-base pseudoaneurysm of the superior mesenteric artery.
abstract: Visceral arterial aneurysm is an uncommon form of vascular disease that has a significant potential for rupture or erosion into an adjacent viscera, resulting in life-threatening hemorrhage. Superior mesenteric artery (SMA) aneurysms are especially rare, comprising only 5-8% of all visceral arterial aneurysms. Traditionally, the most common treatment for SMA aneurysms has been simple surgical ligation of the proximal and distal vessel. Herein, we report the case of a 53-year-old man with a dissecting pseudoaneurysm of the SMA, demonstrated by multi-slice computed tomography and angiography. The patient was successfully treated with percutaneous transluminal angioplasty and stenting.
