Abstract

BackgroundTo evaluate the diagnostic value of transcranial Doppler (TCD) and electroencephalography (EEG) in patients with vertebrobasilar insufficiency (VBI) during clinical diagnosis and treatmentMethodsEighty patients diagnosed with VBI in our hospital from June 2018 to December 2019 were randomly selected as the observation group, and 80 healthy people who received physical examination in the same period were selected as the control group. The abnormal rate, main performance and results, and the peak velocity of blood flow and vertebrobasilar artery blood flow of the two groups were compared.ResultsThe abnormal rate of EEG and TCD in VBI patients was 38.75% (31/80) and the 93.75% (75/80), respectively. In TCD examination, ACA, PCA, MCA, and VA of both sides of the observation group were higher than those of the control group, while BA was lower than that of the control group (P < 0.05). The Vs, Vd, and Vm on both sides of BA and VA in the observation group were lower than those in the control group, while PI and RI were higher than those in the control group (P < 0.05).ConclusionsTCD examination is highly sensitive to the degree and pattern of cerebral ischemia in VBI patients. EEG examination will define the changes of brain cell function after cerebral ischemia. Therefore, EEG and TCD have their own advantages. The application of TCD and EEG can be considered in the early diagnosis, curative effect, and prognosis evaluation of VBI patients, so as to improve the accuracy of diagnosis and prognosis.

Highlights

As a common disease, vertebrobasilar insufficiency mainly refers to the temporary insufficiency of blood supply or ischemic attack of vertebrobasilar artery, which is usually manifested as recurrent or intermittent attack of nerve dysfunction, making patients have nausea and vomiting, tinnitus, vertigo, and other clinical symptoms [1]
The aim of our study was to evaluate the diagnostic value of transcranial Doppler (TCD) and EEG in patients vertebrobasilar insufficiency (VBI) during clinical diagnosis and treatment
The main characteristics were that the blood spectrum was similar to a right triangle, the peak time was delayed and waveform was blunt, the flow velocity on both sides was unbalanced, PI showed a decreasing or increasing trend, the abnormal frequency spectrum S1 ≤ S2, and the image comparison between observation group and control group is shown in Figs. 1 and 2

Summary

Introduction

Vertebrobasilar insufficiency (vertebro-basal artery insufficiency, VBI) mainly refers to the temporary insufficiency of blood supply or ischemic attack of vertebrobasilar artery, which is usually manifested as recurrent or intermittent attack of nerve dysfunction, making patients have nausea and vomiting, tinnitus, vertigo, and other clinical symptoms [1]. Many studies have confirmed that TCD has significant effect [2], but there are few reports on application of EEG in VBI. TCD and EEG will be used to analyze VBI patients in order to evaluate the clinical application value. The aim of our study was to evaluate the diagnostic value of TCD and EEG in patients VBI during clinical diagnosis and treatment. To evaluate the diagnostic value of transcranial Doppler (TCD) and electroencephalography (EEG) in patients with vertebrobasilar insufficiency (VBI) during clinical diagnosis and treatment
