A case of basilar artery occlusion is reported. The patient suddenly developed dizziness and weakness of the right side. Computed tomography scanning showed focal low attenuation in the left quadrangular lobule of the pons. Cerebral angiography demonstrated proximal occlusion of the basilar artery and significant collateral flow in the posterior fossa from the left posterior inferior cerebellar artery (PICA), which arose from the vertebral artery far below the foramen magnum. The literature concerning the origin of the PICA is reviewed.
报告了一例基底动脉闭塞病例。患者突然出现头晕及右侧肢体无力。计算机断层扫描显示脑桥左侧四边形小叶局灶性低密度影。脑血管造影显示基底动脉近端闭塞，枕后窝有来自左小脑后下动脉（PICA）的显著侧支血流，该动脉起源于枕大孔远下方的椎动脉。对有关小脑后下动脉起源的文献进行了综述。
