Rare vascular complication of percutaneous balloon compression of trigeminal neuralgia treated endovascularly

Trigeminal neuralgia is commonly treated with percutaneous balloon compression due to the high success rate, technical simplicity and cost efficiency.1–3 The procedure carries certain risks, most notably dysesthesias and masseter muscle weakness.4 5 However, more severe complications are rare. In this report, the case of a rare complication of percutaneous balloon compression for trigeminal neuralgia is presented, resulting in a carotid cavernous fistula treated via an endovascular approach.
