摘　　要：目的　探讨椎动脉颅内段变异的类型及MRA表现特点 ,提高对桥脑、延髓疾病的影像学认识及诊断水平。方法　经MRA检查后确定椎动脉颅内段变异 2 1例 ,对其变异类型、MRA表现与临床症状的关系进行了回顾性的分析。结果　 7例病人表现为单侧椎动脉颅内段发育不良 ;2例单侧血管节段性闭塞 ;9例单侧椎动脉颅内段硬化迂曲 ,其中有 3例硬化的血管挤入脑干内 ;3例血管瘤 ;各例病人均有不同程度及不同形式的脑干部颅神经功能紊乱或障碍。结论　对于了解椎动脉颅内段变异状态MRA是一种理想的、无创性的有效方法。Objective To investigate variant types and the image features of MRA of intracranial branch of vertebral artery so that to improve the ability in understanding and diagnosing pons and medulla oblongata diseases.Methods Twenty one cases with the intracranial branch of anomaly vertebral artery were comfirmed by MRA.The anomaly types and MRA features,as well as the clincal symptoms were retrospeetively analyzed.Results MRA features of the intracranial branch of vertebral artery in one sides were as follows:Hypoplasia(n=7),Obliteration of some paragraphes(n=2),Sclerosis or increased tortuous and dilatation(n=9);brain stem compressed by the sclerotic vessel (n=3),angioma(n=3).All paticnts had dysfunction of cranionerves of brain stem in different degree and form.Conclusion MRA was a ideal and no tranmatic method to show the anomaly of the intracranial branch of vertebral artery
