小儿脑积水的英文名称是"hydrocephalus in children"。

脑积水（hydrocephalus）是一种神经系统疾病，其特征是大量的液体（称为脑脊液）在脑内积聚，导致脑膜和脑室扩张，从而增大头部尺寸。在婴儿和幼儿时期，脑积水可能会导致头部变大，头皮出现水肿，头部形状异常，眼睛突出，发育迟缓，以及视力问题。

脑积水的来源有多种，可能是由于脑损伤、感染、脑膜瘤、血管畸形或其他原因造成的。它可以在出生时就出现，也可能在以后的几个月或几年内发生。

"My son was diagnosed with hydrocephalus when he was just a few months old. He had to undergo surgery to have a shunt placed in his brain to drain the excess fluid."

"Our daughter was born with hydrocephalus and has had several surgeries to help manage the condition. She has made great progress with therapy and is now able to walk and talk."
