In 24 cases of spina bifida, correlations were made comparing the degree of hydrocephalus with the cross-sectional area of the supratentorial compartment, posterior fossa, hindbrain prolapse, size of myelocele, and degree of fibrovascular reaction at the base of the brain. The size and postion of the aqueduct and fourth ventricle were compared with the degree of hydrocephalus. The results demonstrate that the aqueduct stenosis is usually due to external compression of the mesencephalon. The results also suggest that the size of the posterior fossa and hindbrain prolapse are secondary to hydrocephalus. It is postulated that the hydrocephalic process may be initiated by fibrovascular occlusion of the basal subarachnoid space.
在24例脊柱裂病例中，对脑积水程度与幕上腔室、后颅窝的横截面积、后脑膨出、脊髓脊膜膨出大小以及脑底部纤维血管反应程度进行了相关性比较。将导水管和第四脑室的大小及位置与脑积水程度进行了比较。结果表明，导水管狭窄通常是由于中脑受到外部压迫所致。结果还提示，后颅窝大小和后脑膨出是脑积水的继发性表现。据推测，脑积水过程可能由基底蛛网膜下腔的纤维血管闭塞引发。
