EXTERNAL CAROTID-ARTERY FISTULA DUE TO MICROCOMPRESSION OF THE GASSERIAN GANGLION FOR RELIEF OF TRIGEMINAL NEURALGIA - CASE-REPORT

Vascular complications after percutaneous injection procedures for relief of trigeminal neuralgia are varied, ranging from puncture of arterial or venous structures to carotid-cavernous fistulas. The authors present a patient in whom an external carotid artery fistula occurred after a microcompression procedure for the treatment of a left-sided trigeminal neuralgia. This is believed to be the first case of this complication secondary to a percutaneous injection procedure for relief of facial pain.
