Endovascular Stent Graft Repair of a Ruptured Superior Mesenteric Artery Aneurysm

A ruptured aneurysm of the superior mesenteric artery (SMA) is very rare. In recent years, there have been some reports of successful endovascular therapy of SMA aneurysms. However, endovascular stent graft repair of a ruptured SMA aneurysm has not been reported previously. We report on a 50-year-old man with a ruptured aneurysm of the proximal SMA. Using an endovascular approach, the aneurysm was initially excluded with 2 stent grafts. Two weeks following the first procedure, computed tomography angiography revealed a proximal endoleak, which was treated with another stent graft. The endovascular stent graft repair finally resulted in total exclusion of the ruptured aneurysm. Patency of the SMA was maintained and no ischemic complications occurred.
