Background: The posterior cerebral artery (PCA) is the terminal branch of the basilar artery. The fetal variant of PCA (fPCA) arises directly from the internal carotid artery. A fPCA can be either complete or partial with a hypoplastic segment connecting to the basilar artery. Individuals with fPCA could be more prone to ischemic strokes. Aims: This study aims to analyze the posterior cerebral artery variations on Magnetic resonance (MR) angiogram and its influence on ischemic strokes. Materials and Mmethods: The MR angiogram images of 150 patients - 75 with evidence stroke and 75 without evidence of stroke were analyzed for the presence of fPCA. The origin, diameter, and variations of PCA and posterior communicating artery were analysed for evidence of the presence of fPCA. Results: There were 20 individuals with fPCA out of 75 individuals with evidence of stroke and 9 individuals with fPCA among 75 individuals without evidence of stroke. The presence of fPCA associated with stroke is statistically significant with P-value of 0.0375. Conclusions: The presence of fPCA in an individual is one of the predisposing factors to stroke.
