经颅超声多普勒在头痛头迷儿童中的应用

The Application or Transcranial Doppler Ultrasonography in the Children with Migraine and Dizzy

采用经颅多普勤检查２９４例４～１４岁头痛头迷患儿颅内动脉血流速度。异常７３例（２４．８２％）。其中流速升高６５例，流速降低１５例，双侧不对称２０例，脉动指数升高９例，降低８例。本文确诊典型偏头痛７例普通型偏头痛４４例，基底动脉型偏头痛２２例。作者认为经颅多普勒检测可了解颅内的循环状态协助临床偏头痛诊断及药物选择。

e examined intracranial arterial blood velocities in 294 patients(age 4 to 14 years) with headacheand dizzy, using transcranial doppler ultrasonography(TCD).There were 73 abnormal(24. 82%).Among them the increase in velocity occurred in 65 cases,decrease in 15 cases; the asymmetry in rela-tion to the contralateral side was in 20 cases;the increase in pulsatility index(PI) was in 9 cases,andthe reduction in PI 18.7 cases were diagnosed as typical migraine,44 cases common migraine,22 caseshasilar artery migraine.Our results suggest that TCD will enable us to expand our understanding of in-tracranial circulation and to better select medicines.It may be an objective index for clinical diagnosis ofmigraine.
