The use of a carotid shunt is a well-accepted method for the prevention of cerebral ischemia during carotid surgery. Although carotid surgeons are familiar with the risks associated with shunt use, few reports have been published detailing the nature, incidence, or severity of shunt-related complications. We report on a patient with dilatation of the distal cervical internal carotid artery at the site of Pruitt-Inahara (LeMaitre Vascular, Inc. Burlington, Mass) shunt balloon inflation. To our knowledge, this complication of shunting during carotid endarterectomy has not been previously described.
