Percutaneous ventriculostomy--evolution of a device.

摘要: The technique applied for external ventriculostomy should allow simple, fast, stable and clean performance of this procedure. stepwise development a metallic kit help overcome shortcomings traditional methods such as catheter obstruction propensity infection. A rigid set precoronary puncture was developed, consisting screw with selfbiting conical thread cannula distal holes CSF drainage. rate infection < 2% in nonseptic patients mean duration the 11 days (maximum: 2 months). Hemorrhage occurred 1% patients. Problems were secondary wound healing after prolonged periods place rapid CSF-infection cases loosened screws which not instantly removed. Ventriculostomy can be performed bedside within 5 min clotted cannulas exchanged via indwelling screw. system resterilized titanium device is MRI-compatible. method tested compares favorably conventional techniques ventriculostomy. Use requires continuous education personnel involved order to avoid complications hemorrhage loosening
