【摘要】 目的:利用数字减影血管造影(digital subtraction angiography,DSA)技术观察中枢性眩晕患者脑血管的形态变化,为该病的诊断和治疗提供参考。方法:对临床拟诊为中枢性眩晕的92例患者,全部进行全脑血管DSA检查,并分析血管结构异常的类型、比例及分布(好发部位以及受累血管数目)。结果:中枢性眩晕患者92例,病变137侧,其中前循环(颈动脉系统)病变15侧(10.95%);后循环(椎-基底动脉系统)病变122侧(89.05%),累及两条或两条以上血管的共31例(33.70%),以椎动脉合并其他血管狭窄最为常见。椎-基底动脉系统病变中椎基底动脉狭窄或闭塞39侧(28.47%),大脑后动脉狭窄或闭塞13侧(9.49%),后循环变异59侧(43.06%)。结论:后循环狭窄和变异可能是中老年人中枢性眩晕的主要原因。更多还原

【Abstract】 Objective:To investigate the morphological changes of cerebral blood vessels by digital subtraction angiography(DSA) in patients with central vertigo,so as to provide references for diagnosis and treatment of patients with central vertigo.Methods: Ninety-two patients suffering from central vertigo were subjected to cerebral angiography through femoral artery.The types,proportion,and distribution(site predilection and number of involved vessels) of the cerebrovascular abnormalities were observed and analyzed.Results: Of the 92 patients with central vertigo,cerebrovascular lesions were found in 137 sides,including 15(10.95%)anterior circulation lesions and 122(89.05%)posterior circulation lesions.Thirty-one(33.7%)patients had 2 or more lesions.The most common lesion was vertibroarterial lesion accompanied with other cerebrovascular stenosis.The lesions included 39(28.47%) sides with vertibro-basilar stenosis or occlusion,13(9.49%) sides with posterior cerebral artery stenosis or occlusion,and 59(43.06%) sides with posterior circulation abnormalities.Conclusion: The posterior circulation stenoses or abnormalities might be the major reasons for central vertigo in middle-and old-age patients.更多还原
