超声多普勒观察体外反搏治疗前后的脑血流

A clinical observaton on the therapeutic effect of external counterpulsation on veterbrobasial artery insufficient with doppler ultrasound

目的 探讨体外反搏治疗椎基底动脉供血不足（ＶＢＩ）的疗效。方法 体外反搏治疗椎基底动脉供血不足的前后应用ＴＣＤ各检测椎动脉（ＶＡ）、基底动脉（ＢＡ）、小脑后下动脉（ＰＩＮＣＡ）、大脑后动脉（ＰＣＡ）的平均流速（Ｖｍ）及脉动指数（ＰＩ）１次；ＣＤＦＩ各检测颅外椎动脉血流速度时间积分（ＶＴＩ），平均血流速度（Ｖｍ），收缩期峰速（Ｖｓ）及血管直径 １次进行评价。结果 体外反搏治疗 ＶＢＩ前后，不论是颅内血流 ＶＡ、ＢＡ、ＰＩＮＣＡ、ＰＣＡ的 Ｖｍ、ＰＩ检测结果，还是颅外椎动脉的管径、ＶＴＩ、ＶｓＮ 的ＣＤＦＩ检测结果差别均有极显著性意义（Ｐ＜０．０１）。结论 体外反搏治疗椎基底动脉供血不足，无毒副作用，是一种安全疗效确切的较为理想的治疗方法。

Objective To investigate the therapeutic effects of external counterpulsation therapy on vertbrobasial artery insufficient (VBL). Methods External counterpulsation therapy was taken to treat VBI, and doppler ultrasound to measure the changes of brain blood flow before and after treatment to evaluate its significance for VBI, by the mean velocity (Yin) and pulsine index of VA, BA, PICA and PCA with TCD, and by the VTI, Vm, Vs and the caliber of ex- tracranial veterbral artery with CDFI, respectively. Results All the parameters measured were significantly improved after therapy (P<0. 01) ,compared with that before treatment. Conclu- sion External counterpulsation is an effective therapy to treat VBI in clinical practice, with no significant side effects.
