Since the seminal work on basilar artery (BA) occlusion by Kubik and Adams,1 posterior circulation dysfunction has gained attention in relation to the complexity of neurological manifestations and presumed poor prognosis. However, different selection criteria, sample sizes, and collection methods have often introduced contradictory data. For these reasons, prospective hospital registries collecting consecutive acute stroke cases from determined populations have been developed, such as the Lausanne Stroke Registry2 or the New England Medical Center Posterior Circulation Registry (NEMC-PCR),3 the largest one devoted to posterior circulation stroke.
