摘　　要：目的　研究健康儿童脑血管的发育和脑血流动力学改变。方法　对１０５ 例２ ～１４ 岁健康儿童颅底动脉及颅外段动脉行经颅多普勒（ Ｔ Ｃ Ｄ） 检查，统计出各年龄组诸参数正常参考值。结果　颅底动脉血流速度在２ ～４ 岁 时随着年龄的增加而增快，５ ～７ 岁时达最快，此后随年龄的增长又逐渐减慢（ Ｐ ＜ ０ ．０５ ～０ ．０１） ；颅外段动脉血流速度随年龄增长有下降趋势（ Ｐ＞ ０ ．０５） 。结论　儿童 Ｔ Ｃ Ｄ 是脑血管发育的客观体现。随着年龄的增长，血流速度渐接近于正常成人。Objcetives To study the children′s cerebrovascular development and the change of cerebral blood flow dynamies.Methods The blood flow velocities of craniobasial artery and extracranial artery were measured by TCD in 105 children aged from 2 to 14 years old,and the normal reference value of different ages were calculated out.Results The blood flow velocities of craniobasial artery increased with the increase of ages in 2～4 years.It was the highest in 5～7 years After this,it decreased gradually with the increase of ages ( P <0.05～0.01).The blood flow velocity of extracranial artery tend to fall with the increase of ages.Conclusions TCD is the objective index of children′s cerebralovascular development.With the increase of ages,the velocity is gradually close to normal adult′s.
