目的:探讨眩晕患者椎-基底动脉的血流动力学变化,为临床对眩晕的病因诊断提供依据。方法应用经颅彩色多普勒对100例正常人及130例眩晕患者的椎-基底动脉进行检测,观察频谱形态及血流速度。结果(1)检出率:椎-基底动脉均能显示不明理想的血流信号,检出率(230/230)100%。(2)频谱形态:以心脏收缩后产生的流速最高,并形成频谱的收缩峰,也称为S 1峰。继心脏收缩之后,血流由左心室进入主动脉,对血管产生一定压力,致动脉反应性收缩搏动改变,形成血管搏动波,为S 2峰。100例正常人频谱形态S 1>S 2的96例(96%),眩晕患者中频谱形态S 1>S 2的110例(85%),收缩峰圆钝(S 1>S 2)20例(15%)。(3)血流速度:100例正常人(62.32±5.98)cm/s;眩晕患者中正常范围的42例(42/130)32%,收缩期血流速度(40.61±7.13)cm/s,低于正常的74例(74/130)57%,收缩期血流速度(57.86±7.82)cm/s,高于正常的14例(14/130)11%。结论经颅彩色多普勒超声能对椎-基底动脉供血不足性眩晕的诊断提供可靠的依据。

Objective To study diversification of vertebral basilar artery(VBA)hemo dynamics in vertigo sufferers,Provide the basis for clinical diagnosis on the causes of vertigo.Methods To examine VBA in100normal persons and130vertigo sufferers and to monitor frequency chart conformation and blood flow velocity by transcranial color Doppler.Results (1 )Examination rate:a ideal blood flow signal was generally shown on VBA and examination rate was100%(230/230).(2)Frequency chart conformation:the fastest blood flow velocity cured after shrink of heart,and VBA formed shrink peak of frequency chart,which was S 1 peak.After shrink of heart,the blood flow enter into aorta from the left ventricular and caused much pressure in artery.As a result the artery reactively changed with shrinking and beating,and formed vascular pulsation,which was S2 peak.There are96cases(96%)normal frequency chart conformations S1 >S2 in100normal persons, 110(85%)frequency chart conformations S1 >S2 in vertigo sufferers,and the round and blunt peak of shrink is20(15%).(3)Blood flow velocity:blood flow velocity of100normal controls is Vp62.32 ±7.13(cm/s)with under normal scope was74(57%),and with beyond normal scope was14(1 1%).Conclusion Transcranial color doppler ultrasound to the diagnosis of vertebral basal artery insufficiency vertigo to provide reliable basis.
