Introduction: Foetal origin of posterior cerebral artery is one among the common variants in the circle of willis. In case of cerebral injury due to thromboembolic stroke, the presence of foetal type of PCA may modify its severity and the territory involved. The purpose of this study is to review and to evaluate the potential clinical significance of foetal type PCA in ischaemic stroke. Aim: To analyse whether foetal PCA and its types are associated with ischaemic stroke. Materials and Methods: This is an analytical cross-sectional study conducted from January 2019 to January 2020 to assess the PCA in the 174 patients referred to Magnetic Resonance Imaging (MRI) Brain and diagnosed as ischaemic stroke. Data was entered using Excel sheet and analysed using R v.3. 5.1. Descriptive analysis was performed followed by bivariate analysis. Results: There is no statistically significant relationship between the presence of foetal PCA and ischaemic stroke and the p-value is 0.936. Conclusion: There is no significant association of presence or absence of partial or complete type of foetal PCA with ischaemic stroke. No significant association was also found between the presence of foetal PCA and vascular territory of infarct and laterality of ischaemic stroke.
