Abstract：Objective To discuss the correlation between the transcranial Doppler ultrasound and vestibular function spin test in the diagnosis of central vertigo.Methods From August 2013 to December 2016,86 central vertigo patients in Liaoning Electric Power Center Hospital diagnosis and treatment were selected as the observation group,and the other 86 cases of healthy volunteers were selected as the control group at the same period,two groups were give the vestibular function spin test and transcranial Doppler ultrasound diagnosis,and were to determine the correlation of two methods.Results The amplitude of the observation group was significantly higher than that of the control group (P＜0.05),and the latency of N1 was significantly lower than that of the control group (P＜0.05).There were no significant difference compared between the two groups in the threshold value and the latency of P1 (P＞0.05).The blood flow velocity of vertebral artery and basilar artery in observation group were (20.44±5.33)cm/s and (22.48±4.92)cm/s,respectively,which were significantly lower than that of control group of (34.28±4.98)cm/s and (35.20±4.82)cm/s (P＜0.05).In the observation group,linear correlation analysis showed that the blood flow velocity of vertebral artery and basilar artery were negative correlation to the amplitude (P＜0.05),and were significant positive correlation with the latency of N1 (P＜0.05),but had no obvious correlation with the threshold and latency of P1 (P＞0.05).Conclusion There is a good correlation between the transcranial Doppler ultrasound and vestibular function spin test in the diagnosis of central vertigo,vestibular function spin test helps lesion localization,transcranial Doppler reflects abnormal central nervous system local blood.
