| ABSTRACT |
Objectives:
This study was designed to research whether transcranial doppler ultrasound(TCD) can yield a suitable diagnosis or prognosis for dizziness.
Methods :
To evaluate the blood flow, we measured the mean velocity(Vm), peak systolic velocity(Vs) and pulsatility index(PI) of the middle cerebral artery(MCA), vertebral artery(VA) and basilar artery(BA) in 54 dizziness patients and 44 normal subjects. To investigate the difference between dizziness patients and normal subjects, we selected 54 dizziness patients diagnosed normal by Brain MRI, and 44 normal subjects who did not have any symptoms of hyperlipemia, hypertension, diabetes melitus, heart disease, or smoking, diagnosed normal by Brain MRI. 30-69 year olds were divided into 30-49 year olds, 50-59 year olds and 60-69 year olds.
Results:
In normal subjects, there was a significantly higher Vm, Vs in the MCA and BA, and Vs in the VA of female subjects, and there was a significant difference in PI in the MCA and BA increasing with age. In comparison with normal subjects, dizziness patients had a significantly lower Vm in the BA. Male dizziness patients had significantly lower PI in the MCA. 30-49 year olds had significantly lower Vm in the BA.
Conclusions:
The significant difference in blood flow velocities in the BA between dizziness patients and normal subjects suggests that dizziness is related to blocking of blood flow in the BA and that diagnosis and prognosis can be made through TCD. More detailed study of dizziness patients will be needed. |
