Abstract :The persistent trigeminal artery (PTA) is a persistent, primitive, embryonic anastomosis that provides the blood flow between the vertebro-basilar system and the carotid system. The presence of PTA anastomosis may create an advantage by providing collateral circulation during a stroke as in cases of leptomeningeal collaterals, external-internal carotid artery anastomoses, and the polygon of Willis. However, patients with this variation are more susceptible to the development of non-occlusive posterior arterial system infarction when they experience hypotension attacks. In the literature, there are only few case reports on non-occlusive posterior system infarction associated with PTA variation. In this case report, we present to an 81-year-old patient with posterior system infarct findings and persistent trigeminal artery variation.Keywords : Persistent trigeminal artery, posterior arterial system infarction, hypotension
