摘　　要：目的探讨经颅多普勒（TCD）联合计算机X射线断层扫描技术（CT）对老年患者椎-基底动脉供血不全的诊断价值。方法对比我院50例基本符合椎基底动脉供血不足临床表现的老年患者TCD、CT血管造影（CTA）、数字减影血管造影（DsA）及TCD联合CTA诊断情况。结果50例患者中，TCD确诊42例（84％），CTA确诊45例（90％），DSA确诊48例（96％），TCD联合CTA共确诊49例（98％）。且TCD联合CTA与DSA比较，差异无统计学意义（X^2=0．34，P〉0．05）。结论CTA联合TCD具有较高的诊断准确度，值得老年患者推广应用。Objective To investigate the diagnostic value of the combined transcranial Doppler ultrasound and CT for vertebrobasilar insufficiency in elderly patients. Methods Fifty elderly patients with symptoms of vertebrobasilar insufficiency were enrolled and randomly assigned to 4 groups, including examinations of TCD, CTA, DSA, combination of TCD and CTA. The diagnostic accuracy was calculated and compared. Results Among 50 cases, the vertebrobasilar insufficiency was confirmed in 42 patients （84%） by TCD, 45 （90%） by CTA, 48 （96%） by DSA, 49（98%） by combination of TCD and CTA. There was no significant difference in diagnostic rate between TCD combined with CTA and DSA （X^2 = 0.34, P〉0.05）. Conclusions The diagnosis accuracy of the combined CTA and TCD is high, making it worth popularizing.
