Blunt traumatic transection of the right common carotid artery

Abstract

Background

Carotid injuries are infrequent following blunt traumatic injury but can have potentially devastating neurologic consequences. We present a case of a 31-year-old male with right common carotid transection after blunt trauma to the neck.

Case report

A 31-year-old male with no notable medical history presented as a trauma level one activation after riding his bicycle into an open car door causing a Zone II laceration of his right anterior neck. The patient was hemodynamically normal, had an intact airway and had no neurologic deficits on evaluation in the trauma bay. He underwent a computed tomography angiogram of his neck which revealed a focal dissection of the right common carotid artery causing a 70%–80% luminal narrowing suspicious for a grade II injury. The patient was taken to the operating room for exploration of his neck laceration. He was found to have a grade V injury with complete transection of the right common carotid artery through the intima and media with intact adventitia. The arterial injury was repaired with polytetrafluoroethylene interposition graft. Perioperatively, the patient was started on dual antiplatelet therapy. He recovered uneventfully without neurologic deficits.

Conclusion

Complete transection of the common carotid artery following blunt trauma is rarely reported. Based on a review of the literature regarding blunt carotid injuries, it is reasonable to repair such injuries with prosthetic graft followed by either systemic anticoagulation or dual antiplatelet therapy.
