Facial palsy after neck arteriovenous fistula embolization.

Facial palsy after embolization of neck arteriovenous fistula is an extremely rare complication. In our case, complete facial palsy occurred after embolization and was successfully treated with superficial parotidectomy, vessel ligation, and plug removal. We report the first case of unusual facial palsy that developed 13 days after neck arteriovenous fistula embolization. As a result of our findings, we recommend, when a patient suffers from acute ipsilateral facial palsy after arteriovenous fistula embolization, the clinician should consider the possibility of complications of embolization, and immediate and appropriate management should be performed.
