A Technique for Treatment of Overdrainage in Ventriculoperitoneal Shunt
Background and Importance: Overdrainage is a complication of ventriculoperitoneal shunt but adjustable valves and anti-siphon devices can prevent it. These very expensive valves are most often inaccessible, so that the majority of the valves available in Togo are fixed differential pressure valves. Although overdrainage is a widely-known issue, we aimed to introduce a new risk factor and the wa...
متن کاملThe Value of Programmable Shunt Valves for the Management of Subdural Collections in Patients with Hydrocephalus
BACKGROUND The aim of the present study was to assess the value of electromagnetic programmable shunt valves for the treatment of subdural collections. METHODS Adult patients with hydrocephalus of various causes that were treated with programmable shunt valves during the last ten years were retrospectively studied. In 127 patients, 139 electromagnetic programmable shunt valves were implanted....
متن کاملShunt Devices for the Treatment of Adult Hydrocephalus: Recent Progress and Characteristics
Various types of shunt valves have been developed during the past 50 years, most of which can be classified into the following categories: (1) fixed differential pressure valves; (2) fixed differential pressure (DP) valves with an antisiphon mechanism; (3) programmable DP valves; (4) programmable DP valves with an antisiphon mechanism; and (5) programmable antisiphon valves. When considering th...
متن کاملRandomized trial of cerebrospinal fluid shunt valve design in pediatric hydrocephalus.
OBJECTIVE Forty percent of standard cerebrospinal fluid shunts implanted for the treatment of pediatric hydrocephalus fail within the first year. Two new shunt valves designed to limit excess flow, particularly in upright positions, were studied to compare treatment failure rates with those for standard differential-pressure valves. METHODS Three hundred-forty-four hydrocephalic children (age...
متن کاملChronic ossified epidural hematoma after ventriculoperitoneal shunt insertion: a case report.
Chronic calcified/ossified epidural hematoma is an uncommon complication of ventricular shunt surgery. There are only 4 cases related to valve-regulated shunt operations in the literature. It may be seen especially in young patients with chronic hydrocephalus, probably due to craniocerebral disproportion. The precise mechanism of the calcification or ossification of the hematoma is not known, h...
