经颅超声多普勒对儿童血管性头痛发作期的诊断价值

The Clinical Value of TCD in Diagnosis of Vasculer Migraine in Children

目的 :探讨经颅超声多普勒 (TCD)对诊断儿童血管性头痛发作期的临床价值。方法 :对 3 0名血管性头痛患儿及与之匹配的正常儿童进行TCD检测分析。结果 :儿童血管性头痛患儿发作期颅内外动脉最高平均血流速度 (MFV)低于正常对照组 ;不同程度头痛患儿颅内外动脉MFV比较 ,重度头痛者最低 ,中度者次之 ,轻度者最高 ;各颅内外动脉的脉动指数略低于正常对照组。结论 :儿童血管性头痛发作期存在血流动力学改变。经颅超声多普勒可为诊断该病的重要依据 。

Objective This work was designed to investigate the clinical value of transcranial Doppler sonography(TCD) in dignosis of vascular migraine in children. Method The blood volume of intracranial vessel was measured with TCD in 30 children patients with vascular migraine attack and 30 matched controls.Results The mean flow velocity(MFV) of intracranial vessel in patients with vascular migraine attack was significantly lower than that in the control. There was a parallel relationship between the severity of disease and the MFV. The pulsatility index of internal and external carotid was also lower than that in the control, but no statistical difference was shown.Conclusion The hemodynamics changes in the intracranial vessel were observed in children patients with vascular magraine attack by TCD. TCD study may be useful in diagnosis of vascular magraine and supply a good index for judging the severity of the disease.
