Congenital carotid-jugular fistula in an elderly patient.

Carotid-jugular arteriovenous fistulas (AVF) are extremely rare with only 20 cases reported in the literature up to December 1996. The case of a 74-year-old man (the oldest reported in the literature) with abnormal communications between the external carotid artery and the internal jugular vein is reported. The condition was treated by platinum coil embolization via catheterization and by repeated operations to ligate the branches of the external carotid artery, besides removal of the tissue containing the fistula and ligation of the external carotid at its origin. The result was incomplete because about 6 months after the last operation the patient showed the same symptoms, although in a milder form. Until standard treatment is established, the appropriate technique should be decided on a patient-to-patient basis.
