ABSTRACT

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 followsHypoplasia(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
