Beneficial Effect of Siphoning in Treatment of Adult Hydrocephalus
Arch Neurol 56:1224-1229,1199, Bergsneider,M.,et al, 1999
See this aricle in Pubmed

Article Abstract
Severe clinical manifestations exhibited by the patients, including parkinsonian features, Parinaud syndrome, and extensor posturing, completely reversed once a normalization of ventricular size was achieved. External ventricular drainage pr essures as low as -30 cm H2O were required to reduce ventricular size. All patients finally received a shunt incorporating a standard medium differential pressure valve with no antisiphon device. Shunt siphoning may be an essential mechanism by which ce rebrospinal fluid shunting is effective in many patients with adult hydrocephalus. Cerebrospinal fluid shunts that contain an antisiphon device are ineffective in these patients, despite the attainment of "physiologic" intracranial pressures. Based on r eported experimental and clinical evidence, it seems that the cause of this condition may be related to abnormally high intracranial compliance.
