Transcatheter arterial embolization is effective for mesenteric arterial hemorrhage in trauma

A 58-year-old man was injured in a traffic accident and hemodynamically unstable on admission. An abdominal computed tomography (CT) with contrast enhancement was performed after fluid resuscitation. Fluid accumulated along the mesentery around the cecum. A pseudoaneurysm was found by angiography in the ileal branch. Transcatheter arterial embolization (TAE) was performed in the branch using microcoils. His hemodynamics stabilized after TAE. In a CT performed after 12 h, free air was suspected and an exploratory laparotomy was performed. No intestinal perforations were found and hemostasis was completed in the injured mesentery. No ischemic findings were obtained in the intestines. TAE is one of the treatments of choice for mesenteric hemorrhage.
