It has been presumed that idiopathic normal pressure hydrocephalus is due to obstruction. We visualized the ventricles in 19 patients subsequent to shunting. We found no consistent relationship between clinical improvement after shunting and reduction in ventricular size. This suggests that the positive effect of shunting in at least some instances is due to some other factor than reduced ventricular size.
一直以来人们推测特发性正常压力脑积水是由梗阻所致。我们对19例分流术后患者的脑室进行了可视化观察。我们发现分流术后临床症状改善与脑室大小缩小之间不存在一致的关联。这表明至少在某些情况下，分流的积极效果是由脑室大小缩小以外的其他因素所致。
