彩色多普勒超声检查椎基底动脉供血不足40例分析

Color Doppler Ultrasonic Analysis of 50 Patients with Vertebrobasilar Transient Ischemic Attack

本文对临床诊断为椎基底动脉供血不足的40例彩色多普勒超声检查进行分析,通过测定椎动脉及基底动脉的收缩期最大流速(VS):平均流速(Vm):舒张期最小流速(Vd);脉动指数(PI);阻力指数(RI),结果椎基底动脉的异常率为80％。为临床诊断椎基底动脉供血不足的诊断提供了客观依据指标。

Vertebrobasilar VS, vm, vd, PI and RI were detected by color Doppler ultrasonic examinations in 40 patients having been clinically diagnosed as vertebrobasilar transient ischemic attack (TTA). The analytic results showed that the incidence of vertebrobasilar abnormities was 80%, providing an objective basis for clinical diagnosis of vertebrobasilar TIA.
