Diagnostic value of brainstem auditory evoked potential combining with Doppler ultrasound in ;elderly patients with vertigo / 中国医学装备

ABSTRACT

Objective: To explore the diagnostic value of brainstem auditory evoked potential (BAEP) combining with transcranial Doppler ultrasonography (TCD) in elderly patients with vertigo. Methods:54 cases of elder patients with confirmed in elderly patients with vertigo were selected as the observation group and 51 patients without vertigo and neurological signs were selected as the control group. Two groups of patients were underwent brainstem auditory evoked potential (BAEP) combining with Doppler ultrasonography, which were examined in carotid artery, internal carotid artery and other arteries by Doppler ultrasound. The peak latency and I, II and V wave amplitude were measured by brainstem auditory evoked potential, and the pulsation index and resistance index (RI) were compared between the two groups. Results: Patients in the observation group probability was significantly higher than the control group in the basilar artery stenosis, unilateral vertebral artery stenosis, bilateral vertebral artery stenosis and unilateral vertebral artery hypoplasia(x2=8.872, x2=8.523, x2=11.238, x2=12.351;P<0.01). There were differences between them. The comparison between V wave peak latencies and III~V wave peak latencies were significantly different (t=4.381, P<0.01). The total abnormal rate in the observation group (81.5%) was significantly higher than that of the control group(25.5%). The differences were statistically significant (x2=9.758, P<0.01). Conclusion: The diagnostic value was high for elderly patients with vertigo brainstem auditory evoked potential in combination with Doppler ultrasound.
