title: External carotid artery fistula due to microcompression of the gasserian ganglion for relief of trigeminal neuralgia. Case report.
abstract: 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.
