Abstract：Objective To investigate the predisposing factors and anatomical basis of patients with posterior circulation ischemia (PCI) in anomalous vertebrobarsilar artery by 128‐slice spiral CT ,angiography (CTA) of cerebral and carotid . Methods A total of 729 patients diagnosed or suspected as PCI were examined by 128‐slice CTA .There were 204 patients (27 .9% ) diagnosed as anomalous vertebrobarsilar artery .We analysed retrospectively the position and quantity of anoma‐lous vertebrobarsilar artery in origin ,path ,caliber and fenestration ,and the correlation of PCI .Results Among of 204 patients with PCI ,merely vertebral artery dysplasia was 50 cases (6 .86% );Merely vertebral artery anomalous path was 37 cases (44 vertebral arteries ,5 .08% );Vertebral artery fenestration was 33 cases (4 .53% );Alone vertebral artery formed basilar artery was 29 cases (3 .98% );Anomalous origin and path anomalies was 28 cases (3 .84% );Anomalous origin and vertebral artery dysplasia was 21 cases (2 .88% );Merely vertebral artery anomalous origin was 5 cases (0.69% );Vertebral artery duplication was 1 case (0 .14% ) .Conclusion Anomalous vertebrobarsilar artery is the one of the important predisposing factors of PCI ,128‐slice CTA examination can display the various development anomalous of vertebral basilar artery and anatomic anomalies quickly ,noninvasively and intuitively ,which provides reliable and impor‐tant radiological and anatomical basis for clinical research in anomalous vertebrobarsilar artery and correlation of PCI .
