摘要
目的了解各月龄婴儿脑室大小的正常范围。方法采用颅脑超声对２５５例正常婴儿的脑室进行了测量。其中２０例婴儿从出生一直跟踪随访至１２个月，观察脑室大小变化。结果男女婴儿脑室大小无显著差别。分娩方式对脑室大小无明显影响。３个月和６个月婴儿的头围、大脑半球宽度及脑室测定值均分别大于新生儿和３个月婴儿。１２个月婴儿的头围和大脑半球宽度均显著大于６个月婴儿，但脑室测定值与６个月婴儿相比，差异已无显著意义。结论随着婴儿年龄增加脑室也逐渐增大，但６个月后脑室增大速度明显减慢。
Objective To obtain a reference range of ventricular size values from serial measurements in different age of infants. Methods The authors carried out ultrasonographic imaging of the brain in 255 normal infants. Twenty infants were followed up from birth to 12 months of age. Results there was no significant difference in ventricular size between male and female infants, nor among vaginal delivery, cesarean sections and forceps application. The head circumference (HC), cerebral hemisphere (CH) and ventricular size at 3 and 6 months of age were significantly larger than those in newborn period and 3 months respectively. The HC and CH were greater at 12 months than at 6 months. But there was no significant difference in ventricular size between 6 months and 12 months old infants. Conclusion The study showed that the ventricular size increased as age increased, but the growth velocity of ventricle greatly decreased after 6 months of age.
