Angiographic embolization of traumatic hepatic artery pseudoaneursym

The development of hepatic artery pseudoaneurysm represents a difficult therapeutic challenge as a vascular complication of hepatic trauma. Depending on the location of the pseudoaneurysm, this complication may represent a substantial technical challenge: recently hepatic artery pseudoaneurysms have been managed nonoperatively in selected patients. We report definitive control of a traumatic hepatic artery pseudoaneurysm with angiographic placement of detachable silicone balloons that allowed precise proximal and distal occlusion. Follow-up arteriogram at four weeks confirmed complete occlusion of the isolated segment without recurrence. The use and fate of detachable silicone balloons are discussed.
