目的探讨经颅多普勒(CDT)联合颈部彩色多普勒超声(CDFI)检查对椎-基底动脉供血不足的诊断价值。方法对临床椎基底动脉供血不足患者130例和70例健康正常人进行经颅多普勒超声(TCD)与彩色多普勒超声(CDFI)检测。结果经颅多普勒超声(TCD)灵敏度度65.6%,特异性92.2%,彩色多普勒超声(CDFI)灵敏度91.4%,特异性86.5%。结论在椎-基底动脉系统缺血性疾病的超声检测中,是否能做出正确诊断的关键是将经颅脉冲多普勒超声和彩色多普勒超声进行联合检查,对颅外椎动脉、颅内椎-基底动脉相互结合进行综合分析,可减少单一检查的片面性,使诊断的准确性得到进一步提高。
Objective To investigate the diagnostic value of transcranial Doppler (CDT) combined with cervical color Doppler ultrasound (CDFI) in the diagnosis of vertebrobasilar insufficiency. Methods Transcranial Doppler ultrasonography (TCD) and color Doppler echocardiography (CDFI) were performed in 130 patients with vertebrobasilar insufficiency and 70 healthy controls. Results Transcranial Doppler ultrasonography (TCD) showed a sensitivity of 65.6% and a specificity of 92.2%. Color CDFI showed a sensitivity of 91.4% and a specificity of 86.5%. Conclusion The key to the correct diagnosis of ischemic vertebral-basilar artery disease is to combine transcranial pulse Doppler ultrasonography and color Doppler ultrasonography to detect the extracranial vertebral artery, Internal vertebral - basilar artery combined with a comprehensive analysis can reduce the one-sidedness of a single examination, so that the diagnostic accuracy has been further improved.
