Facial palsy following embolization of a dural arteriovenous fistula.
Intracranial arteriovenous malformations are infrequent. Advances in endovascular treatment techniques have promoted the use of endovascular embolization in management of intracranial arteriovenous malformations. Transvenous or transarterial embolization procedures are effective options in the treatment of the arteriovenous fistulas. However, complications such as cranial nerve palsies may occur. Here, we present a case of right-sided lower motor neuron facial paralysis due to embolization of an intracranial dural arteriovenous fistula that have presented with clinical findings on the left eye. Facial functions of the patient improved from total weakness to House-Brackmann grade II, following facial nerve decompression surgery.
