摘要
目的 研究偏头痛患儿的脑动脉血流动力学改变 ,探讨其在小儿偏头痛发生中的作用。方法 应用经颅多普勒 (TCD)技术 ,检测 90例 7～ 14岁头痛间歇期的偏头痛患儿和 80例健康同龄儿童脑动脉血管血流动力学指标。结果 90例偏头痛患儿中脑动脉血流动力学异常者 77例 (86 % ) ,其中 6 0例 (6 7% )流速增快 ,9例 (10 % )减慢 ,与对照组相比 ,差异具有显著性 (P <0 0 1) ;90例中 2 3例 (2 6 % )存在双侧同名动脉血流速度不对称 ,其中伴有血流速度异常者15例 ,血流速度正常者 8例 ,差异具有显著性 (P <0 0 1)。结论 脑动脉血流动力学因素异常改变 ,在小儿偏头痛的发生中具有重要作用。尤其值得注意的是 ,双侧同名动脉流速不对称的改变 ,在小儿偏头痛的发生中同样可能起着重要的作用。
Objective To study brain artery hemodynamics in migarine children.Methods Transcranial Doppler(TCD) recording was performed in 90 children with migraine (study group) during interval period and 80 normal children(control group). Results 77 of 90 children with migraine(86%) had abnormal blood velocity in brain artery, with 60 (67%) accelerated and 9 decelerated. 23 cases (26%) had bilateral dys-symmetry between the same arteries in both sides, in which 15 cases had abnormal flow speed, and 8 cases were normal. There was a significant difference bewteen the two groups ( P <0 01).Conclusion Brain artery hemodynamics abnormality exists in some children with migraine, suggesting its important roles in children migraine.
