经颅多谱勒对头痛头晕的诊断与评估

Diagnosis and Assessment of Headache and Dizziness by Transcranial Doppler

经颅多谱勒超声(TCD)对160例头痛头晕患者进行颅内动脉血流检测,结果表明139例患者颈内动脉、大脑前动脉、大脑中动脉、椎-基底动脉均有不同程度的血流速度异常及频谱形态改变,21例流速无异常,但双侧血流不对称.说明TCD检测结果可作为临床诊断头痛头晕等疾病辅助诊断手段.

Transcranial Doppler (TCD) was used to test the blood stream of cranial artery of 160 cases of headache and dizziness.The results show that 139 cases had abnormal blood stream velocity and spectrum change in internal carotid artery,arteria cerebri anterior,arteria cerebri media,and vertebrate-basilar artery;21 cases had no abnormal velocity but with asymmetrical bilateral bloodstream.These results prove that TCD is a supplementary method to diagnose headache and dizziness.
