A hybrid repair of a superior mesenteric artery pseudoaneurysm using open mesenteric bypass and endovascular exclusion.

Superior mesenteric artery (SMA) aneurysms and pseudoaneurysms are uncommonly encountered in vascular surgery practice, but they typically require repair. Historically, they have been repaired with open aneurysmorrhaphy, bypass and exclusion, or simple ligation. More recently, endovascular repair with coil embolization and stent graft exclusion have been advocated. We present a repair of an SMA pseudoaneurysm via a hybrid approach with common hepatic artery to SMA bypass, exclusion of the pseudoaneurysm with ligation of the SMA proximal to the bypass, plug occlusion of the proximal SMA, and coil embolization of the pseudoaneurysm.
