Common iliac artery injury from blunt trauma: case reports.

Common iliac artery injury from blunt trauma is uncommon. We describe two cases of common iliac artery injury from blunt abdominal trauma resulting in occlusion in one case and aneurysm in the other. The diagnosis of such injuries is based on clinical suspicion, the presence of bruits, pulse change or discrepancy, or continued unexplained blood loss. Vessel wall damage may not manifest itself initially but may result in thrombosis, subintimal hemorrhage, dissection, or aneurysmal dilatation. These can result in hemorrhage, pain, or ischemia developing remotely from the initial trauma.
