Abstract:
Omental artery aneurysms are a unique subset of splanchnic artery aneurysms that are associated with intraperitoneal hemorrhage and high mortality rates. Detecting omental artery aneurysms prior to rupture is especially challenging; as such there are limited data surrounding unruptured aneurysms. Various methods of treating ruptured omental artery aneurysms have been previously described including omentectomy and transcatheter arterial embolization. Because of the mortality rate associated with ruptures, elective intervention in unruptured splanchnic artery aneurysms is recommended regardless of their size. This report details the successful embolization of an unruptured omental artery aneurysm utilizing a percutaneous approach.
