150例中枢性眩晕的DSA改变

DSA changes in 150 patients with central vertigo

目的利用数字减影血管造影技术研究中枢性眩晕患者的脑血管形态变化。方法对150例中枢性眩晕患者行主动脉弓及全脑血管造影,分析颈内动脉及椎基底动脉系统血管结构异常的类型、分布及比例。结果中枢性眩晕患者150例中,114例(76.0%)血管有病变,其中单纯颈内动脉病变7例,单纯椎基底动脉系统病变98例,9例两个系统均存在病变,其中,椎基底动脉系统狭窄或闭塞85例,占56.7%。结论椎基底动脉系统各种类型的血管结构异常是中枢性眩晕的重要原因。

Objective To investigate the morphological changes of cerebral vessels by digital subtraction angiography （DSA） in patients with central vertigo.Method 150 patients with central vertigo were treated with digital subtraction radiography in aortic arch and aortocranial angiography.Type,distribution and proportion of vessel structural abnormity of carotid artery and vertebrobasilar system were observed and analyzed.Results Of the 150 patients with central certigo,cerebrovescular lesions were found in 114 patients （76.0%）,including 7 patients with simple carotid artery system lesion,98 patients with simple vertebrobasilar system lesions,and 9 patients with lesions of both systems.In those lesions,vertebrobasilar stenosis and occlusion were found in 85 cases.ts propoportion was 56.7%.Conclusion Various types of vessel structural abnormity in vertebrobasilar system are the main factor of central vertigo.
