偏头痛被认为与颅内血管舒缩功能异常有关。经颅多普勒超声(TCD)做为一种无创伤性检查技术对颅内主要动脉的血流速度进行检测,从而较客观的反映颅内血管机能状态的改变。 1 资料与方法 1.1 一般资料:根据国际头痛协会1988年制定的分类诊断标准,诊断的偏头痛发作期病人29例,女19例,男10例;年龄13～45岁,平均33.4岁。正常对照组20例,男8例,女12例,年龄18～48岁,平均31.5岁,均为无任何疾病的健康人。 Migraine is thought to be associated with abnormalities of intracranial vasomotor function. Transcranial Doppler ultrasound (TCD) as a noninvasive technique to detect the velocity of blood flow in the main intracranial arteries, which objectively reflects the change of intracranial vascular function. 1 Materials and Methods 1.1 General Information: According to the classification criteria established by the International Association of Headache Association in 1988, there were 29 patients diagnosed as migraine headaches, 19 females and 10 males, aged from 13 to 45 years with an average of 33.4 years. Normal control group of 20 patients, 8 males and 12 females, aged 18 to 48 years old, average 31.5 years old, are healthy people without any disease.
