Intraoperative evaluation of a pulsatile oropharyngeal mass during adenotonsillectomy

Iatrogenic injury to the internal carotid artery (ICA) is a rare complication of pharyngeal surgery that most commonly occurs in children with an anomalous course to the internal carotid artery. Most aberrant arteries are asymptomatic. They can remain undiscovered preoperatively or be found incidentally on radiographic studies completed for an unrelated reason. Evaluation of definitive internal carotid artery injuries is well documented in the trauma literature. We present a case of a suspected intraoperative injury to the internal carotid artery during routine pharyngeal surgery. Ultimately no injury was found, however, aberrant internal carotid arteries were coincidentally discovered. (c) 2005 Elsevier Ireland Ltd. All rights reserved.
