La ventricolocisternostomia (VCS) può essere risolutiva in alcuni casi di idrocefalo con pervietà dell'acquedotto di Silvio, probabilmente grazie alla rapida trasmissione dell'onda pulsatile negli spazi subaracnoidei. Vengono descritti 17 casi di idrocefalo normoteso con prevalente dilatazione triventricolare dell'anziano, trattati con VCS. Sette pazienti sono migliorati, sette sono rimasti invariati e tre sono peggiorati, per cui è stato applicato uno shunt ventricoloperitoneale. Il miglioramento clinico nel 45% dei casi è un dato incoraggiante, che permette di proporre l'intervento endoscopico in casi selezionati.
