Blunt injury to the external iliac artery: a case report.

Blunt vascular trauma is rare as compared with penetrating vascular trauma. The incidence of iliac artery injury has been reported as low as 0.4 per cent of total arterial trauma. Iliac artery injury in blunt trauma is rare because of its anatomic location and protection by the pelvis. This article presents a case of external iliac artery injury secondary to blunt trauma. A deceleration-type mechanism is suggested that results in the production of an intimal flap and later vessel thrombosis. We discuss the clinical details of presentation and angiographic diagnosis as well as treatment options.
