Low pressure valves with ventriculoperitoneal shunts have been proven to lead to good outcomes in the treatment of idiopathic normal pressure hydrocephalus. However, overdrainage complications are often seen with low opening pressures. Efforts have been made to obtain good outcomes without overdrainage complications by decreasing the hydrostatic pressure component using ...
