针刺对椎-基底动脉供血不足血流速度的影响

目的 观察针刺对椎-基底动脉供血不足（VBI）血流速度的影响。方法 本研究将VBI患者依照经颅多普勒检测表现的不同分为两种类型：低流速型和高流速型。系统观察了针刺风池、天柱及C4．6夹脊对两种不同类型VBI患者的椎-基底动脉血流速度的影响。结果与结论 针刺风池、天柱、C4.6夹脊穴既可使椎-基底动脉异常减慢（低流速型）的血流速度升高，又可使异常加快（高流速型）的血流速度减慢，即可针对椎-基底动脉的不同病理状态调节椎-基底动脉的血流速度，使之趋于正常。

The Influence of Acupuncture on Vertebrobasilar Flow Velocity in Vertebrobasilar Ischemia(VBI)

Objective To investigate the influence of acupuncture on vertebrobasilar flow velocity in vertebrobasilar ischemia. Methods According to the different results of transcranial Doppler(TCD), vertebrobasilar ischemia(VBI) was classified under two types: low flow velocity and high flow velocity. The influences of acupuncture at Fengchi (GB 20), Tianzhu (BL 10) and C_ 4-6 jiaji on vertebrobasilar flow velocity were systematically investigated in the two different types of VBI patients. Results and Conclusion Acupuncture at Fengchi (GB 20), Tianzhu (BL 10) and C_ 4-6 jiaji points can not only increase abnormally low vertebrobasilar flow velocity (low flow velocity type) but also reduce abnormally high vertebrobasilar flow velocity (high flow velocity type), that is, it can regulate vertebrobasilar flow velocity and make it tend to be normal according to different vertebrobasilar pathology.
