Persistent trigeminal artery (PTA) is the most common remnant of primitive circulation communicating the developing carotid and vertebrobasilar junction. Although discovered incidentally, an altered hemodynamic may lead to an increased association of aneurysms, vascular malformations and stroke. Neurosurgeons should be aware of the presence and significance of PTA while interpreting imaging and planning interventions.
