Seatbelt injury to the common iliac artery: report of two cases and review of the literature.

Blunt trauma to the common iliac artery is rather rare. Moreover, seatbelt injuries to the common iliac artery have not yet been reported. This article presents two cases of seatbelt injury involving the common iliac artery. A deceleration-type mechanism is suggested as the primary cause of injury, resulting in the production of an intimal flap. The diagnosis of such an injury is based on clinical suspicion, a change of pulse, or lower limb ischemia. On arteriotomy the damage is greater than seen on external examination. Once diagnosed prompt treatment should follow to prevent loss of life or limb. The signs, symptoms, and modalities of treatment are reported, as well as a review of the literature.
