| Description | Overdrainage is one of the complications of normal pressure hydrocephalus as well as of hydrocephalus in general. The authors of this paper compared the impact of fixed pressure valves and programmable valves with gravitational units or anti-siphon devices on the development of overdrainage. We analyzed a group of 82 patients recruited between 2003 and 2011 with the mean age of 66.8 years (median 67.2 years), 42 of which were implanted with fixed pressure valves and 40 were implanted with programmable valves. Overdrainage was identified in 8 (19.0%) of the 42 patients with fixed pressure valves. There was no need for surgical revision in the group of patients with the programmable valves, except for one patient who failed to attend a planned follow up visit and arrived 11 months later. Programmable valves with gravitational units or anti-siphon devices reduce significantly the incidence of complications from overdrainage. They contribute to improved results of surgical therapy in patients with normal pressure hydrocephalus and reduce the need for shunt revisions. |
