Abstract:
Objective To evaluate the basilar artery hemodynamical changes in cervical rotation and ventral flexion by color Doppler flow imaging(CDFI). Methods Basilar artery blood flow were detected during cervical With cervical right lateral,left lateral rotation and ventral flexion, the detection ratio of basilar artery by ultrasound were 89% ,84% ,81% respectively. There were no difference in statistics between the detction ratio of three kinds during cervical flexion,peak systolic velocity(PSV) and end-diastolic velocity(EDV) decreased apparently during left lateral rotation,which did not change during right lateral rotation. No changing was found with resistant index between the three kinds of cervical position. Conclusions The hemodynamic changing of basilar artery during cervical rotation and flexion could be detected by CDFI accurately,which might be useful in clinical study.
