title: Simplified catheterization of a left common carotid artery arising from the innominate trunk.
abstract: Catheterization of the left common carotid artery arising from an innominate artery can be achieved without catheter exchange. An open loop can be created in the left subclavian artery with a preformed catheter. Withdrawal and rotation of the catheter permits catheterization of the anomalous carotid vessel.
