Objective: The aim of the present study was to clarify whether flow-regulating shunt
valves (Orbis Sigma Valve [OSV]) are advantageous in adult communicating
hydrocephalus with regarding to shunt complication and surgical revision rate in
comparison with standard differential-pressure valves (DPV).
Methods: During a three-year period, 84 DPV and 62 OSV were implanted by two
neurosurgeons for adult patients with communicating hydrocephalus. Patients
medical charts were analyzed retrospectively for demographic data, diagnosis at
shunt implantation, valve type, incidence of shunt complications and surgical revision
rate.
Results: The causes of communicating hydrocephalus of adults between two groups
showed no differences; the leading three were cerebrovascular accident (CVA),
traumatic brain injury (TBI) and idiopathic normal pressure hydrocephalus (NPH).
The incidence of subdural collections was lower in the OSV group (11.9%, DPV vs
3.2%, OSV, P<0.05). However, the postoperative complication rate and surgical shunt
revision rate did not have statistically significant difference between two groups in
our study.
Conclusions: In our retrospective study, the OSV shunt had the advantage of
reducing incidence of non-traumatic subdural collections in the treatment of
communicating hydrocephalus of adults. |
