Asymptomatic carotid artery occlusion from a gunshot. The role of angiography in penetrating neck trauma.

Recognition of a carotid artery injury after a gunshot neck wound can be difficult to make in the absence of physical signs. Currently, the usefulness of preoperative angiography in detecting penetrating neck trauma is controversial. We present a case of an angiography proven asymptomatic carotid artery occlusion after a gunshot. Indications for angiography after neck trauma are discussed.
