| 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。[ |

| 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 eireulatlon stenoses or abnormalities might be the major reasons for central vertigo in middle- and old-age patients.[ |
