Analysis The Indices Of Vertebrobasilar Insufficiency By Transcranial Color Doppler Flow Imaging

To evaluate the clinical of transcranial color Doppler ultrasonography indices to diagnose of vertebrobasilar insufficiency. The indices include former indices ( Systolic speed, diastole speed, obstruction index, the complying of blood vessel) and new indices ( average speed, resistance height, tensity degree, pressure index, slowdown index, vascular load).MethodsThe group one was 30 hypertensive patients with dizzy or the transient nervous system damaged. Head CT check has been used to demonstrate that the patients have no cerebral hemorrhage, cerebral infarction and other cerebrovascu-lar diseases. The patients have no ear department and ophthalmology disease. Another 30 cases of healthy physical examination person were taken as control group. Adopt ultrasound-9 type color ultrasound diagnose appearance which was made by U. S. A. ATL company. Transcranial color Doppler flow imaging was performed through occipital window. Obtain " Y" blue color flow, about vertebral artery and basilar artery. Carry on above-mentioned index test above-mentioned artery separately, analysis statistics test value.ResultsCompared with control group, the systolic speed and diastole speed of the patients are lowered obviously, p <0. 01. Resistance height(RH) , tensity degree (TD) , average speed (AS) , slowdown index (SI) reduce obviously, pres-sure index (PI) , vascular load(VL) increase obviously, p <0.01.ConclusionAverage speed of cerebral vascular, resistance height, tensity degree, pressure index, slowdown index, vascular load are new transcranial color Doppler flow imaging indices in clinical diagnosis for vertebrobasilar insufficiency...
