Traumatic rupture of external carotid artery: Report of emergency treatment with Guglielmi detachable coil

Carotid dissection is a major complication of blunt head and neck trauma. The authors describe a case report of sudden bleeding of a distal branch of the external left carotid artery caused by a fracture of the mandible. This event occurred a week after the trauma. After a first phase consisting in cardiopulmonary resuscitation and blood loss replacement, the placement of a Guglielmi detachable coil (GDC) was considered the best and safest way to stop the bleeding. Guglielmi detachable coil represents a good technique for emergency treatment of bleeding from distal carotid vessels. Given its high cost, the diagnostic study of vessels near mandible fractures should not be considered as routine in cases of head and neck trauma, but should be considered in the presence of local hemorrhage or suspicious neurologic signs.
