椎-基底动脉供血不足患者椎动脉颅外段及颅内段超声对比观察

Comparative study between CDFI and TCCD in vertebrobasilar insufficiency

目的 探讨椎 基底动脉供血不足 (VBI)患者椎动脉颅外段和颅内段检测结果的相关性。方法 对 2 10例VBI患者 ,采用CDFI和TCCD检查 ,并对两种检查结果作对比分析。结果 CDFI诊断VBI的敏感性为 80 .95 % ,TCCD为 89.0 5 % ,二者结合的敏感性为 92 .86%。两种检查结果一致者为 77.14 % (162例 ) ;结果不一致者 48例 ,占 2 2 .86%。结论 多数VBI患者椎动脉颅外段和颅内段的检测结果明显相关 ,但也存在部分患者两种结果不一致 。

Objective To evaluate the relations between color Doppler flow imaging (CDFI) and transcranial color Duplex sonography (TCCD) in diagnosing vertebrobasilar insufficiency (VBI). Methods The CDFI and TCCD were practised in 210 patients of VBI, and the results were comparatively analyzed. Results The diagnostic sensitivity of CDFI and TCCD in patients of VBI was 80.95% and 89.05%, respectively, and 92.86% of CDFI combined with TCCD. The results of both techniques accorded with each other in 162 cases (77.14%). Conclusion Combination of CDFI and TCCD can increase the diagnostic accuracy of VBI.
