TORRES-RAMIREZ, Luis E et al. Persistent trigeminal artery: three case reports. Rev Neuropsiquiatr [online]. 2014, vol.77, n.2, pp.110-115. ISSN 0034-8597.

Persistent trigeminal artery is a rare vascular disorder and represents the permanence of the communication between the carotid system and vertebrobasilar system after birth. This persistence has been associated with the existence of other alterations of brain vascular morphology and different clinical conditions. We report three cases of persistent trigeminal artery, two incidental findings in patients with transient symptoms and one in a patient with subarachnoid hemorrhage, identified by three-dimensional reconstruction of images obtained by angiotomography.
