| 摘 要： | 目的分析缺血性脑血管病颅内动脉狭窄或闭塞患者经颅多普勒（TCD）、数字减影血管造影（DSA）结果不符原因。方法120例缺血性脑血管病患者分别行TCD和DSA检查。分析两者结果及不符原因。结果120例患者TCD检查1304条血管，检测狭窄动脉172支，闭塞16支；DSA检查血管1534条，发现狭窄动脉233支，闭塞26支，颅内闭塞17支。TCD与DSA符合156支，TCD诊断血管狭窄的敏感性为85．7％，特异性为98．2％，假阳性率为9．3％，假阴性率2-3％。结论TCD是诊断颅内动脉狭窄的重要而无创性检查方法。由于其技术局限性，结果与DSA存在一定差异．改进检查技术，可进一步提高精确性。

| Abstract: | Objective To analysis the disagreement between transcranial Doppler (TCD) and digital subtraction angiography (DSA) in patients with ischemic cerebrovascular diseases caused by intracranial artery stenosis or occlusion. Methods 120 patients with ischemic cerebrovascular diseases were tested by TCD and DSA, the results and the reason of the disagreement were analysed. Results 1304 arteries in 120 patients were examed by TCD, which showed 172 stenotic arteries,156 of which were confirmed with DSA. The sensiti... |
