Posterior circulation ischemic stroke. Risk factor features, genetic associations and neurovascular anatomy, including findings from the SiGN, MRI-GENIE and GISCOME studies.

We aim to investigate differences in risk factors and ischemic stroke subtype in an ischemic stroke
population diagnosed with MRI-DWI as PCiS or ACiS and to use these enriched image-based stroke phenotypes to evaluate differences in genetic contribution to the risk of PCiS vs. ACiS. Our aim is also to compare the prevalence and laterality of a fetal posterior cerebral artery (FTP) in our ischemic stroke population with a mixed hospital-based population investigated with CTA.
