Endovascular management of the carotid blowout syndrome

Abstract

Bleeding from the carotid artery or its branches (‘carotid blowout’) is a well recognized complication following treatment or recurrence of head and neck cancer. The traditional surgical treatment for carotid blowout is often technically difficult and is associated with an unacceptably high morbidity and mortality. The majority of such patients are currently treated conservatively with end of life supportive measures.We report the case of a young patient with recurrent supraglottic carcinoma complicated by carotid blowout on two separate occasions over a five month period, which was successfully treated endovascularly under local anaesthetic, without neurological sequelae. With the continuing development of interventional radiology, endovascular techniques are now emerging as a viable, low morbidity treatment option in selected patients.
