Vertebral Artery Blood Flow Changes in the Spectrum of the Diagnostic Significance of Posterior Circulation Ischemia

Huang Zhiling;He Huaan;Department of Ultrasound,Dayong Hospital;  
Purpose: To investigate the changes in the spectrum of the vertebral artery blood flow after ischemia diagnosis cycle( PCI) significance. Materials and Methods: The clinical diagnosis of 97 cases of patients with diseases of the brain as the case group,while select healthy control group of 60 patients,the use of color Doppler ultrasound in patients with an inner diameter of each of the vertebral artery,course,flow imaging and flow spectrum feature to detect structural differences between the vertebral artery and blood flow parameters between the two groups,the results and brain CTA examination and clinical manifestations concurrent control,analysis of vertebral artery blood flow changes in the spectrum with posterior circulation ischemia relevance. Results: Ultrasound diagnosis of vertebral artery blood flow in patients with abnormal frequency spectrum 92 cases,the positive rate of 94. 8%; control group,there were 11 abnormal cases,the positive rate of 18. 3%,the positive rate was significantly higher in the case group( P 0. 05) in which case group vertebral artery diameter,PSV,EDV,Vm index,significantly lower than the control group( P 0. 05); the case group vertebral artery RI,PI,significantly higher than the case group( P 0. 05). Conclusion: The vertebral artery blood flow changes in the spectrum of the posterior circulation ischemia correlated,ultrasonic testing vertebral artery diameter,course and flow spectrum circulation ischemia after diagnosis has important clinical role.
