Abstract
The association of persistent trigeminal artery (PTA) with intracranial vertebral artery fenestration is very rare. The commonest associations of PTA are with intracranial aneurysms, arteriovenous malformations, absence of internal carotid artery and vertebral arteries. We describe a case of persistent trigeminal artery associated with intracranial vertebral artery fenestration in a patient with right-sided type 1 carotid-cavernous fistula. To our knowledge, this is the first report of such an association.
