Arterial injuries in association with blunt, non-penetrating trauma are recognized with increasing frequency. While the arteries of the extremities are most commonly involved, visceral arteries are occasionally affected. Partial disruption of the arterial wall with thrombosis is the most frequent injury. Arteriography has assumed increasing importance in defining the site and extent of peripheral arterial injuries. Failure to diagnose such injuries early can lead to irreversible ischemic changes or death. The most effective treatment for such injuries is early exploration and re-establishment of arterial continuity.
