The brains of 30 children with hydrocephalus (but not myelomeningocele) were examined. It was found that secondary pressures on the tectum and aqueduct resulting from the hydrocephalus were responsible for further obstruction at this level in 15 of the 30 children and that they contributed to axial distortion in another 11 children. Occlusion of the aqueduct occurred as a result either of these external pressures or of internal gliosis. These events form a self-sustaining cycle which, if broken early, may lead to a more satisfactory control of the hydrocephalus.
对30名患有脑积水（但无脊髓脊膜膨出）的儿童的大脑进行了检查。结果发现，脑积水对中脑顶盖和导水管产生的继发性压力导致30名儿童中有15名在该水平进一步梗阻，另有11名儿童出现轴向扭曲。导水管闭塞是由这些外部压力或内部胶质增生引起的。这些情况形成了一个自我维持的循环，如果早期打破这个循环，可能会使脑积水得到更满意的控制。
