Abstract
Emergency situations, such as acute hydrocephalus or ventricular hemorrhage, require immediate and reliable treatment by ventriculostomy. The method used has to be standardized, applicable in a fast manner, and associated with only minimum risk of infection. We present a recently developed set for external ventriculostomy, which meets the above-standing requirements, and which consists of a screw with self-biting thread, a metal cannula, and a special screwdriver. Ventriculostomy can be performed easily within 2 minutes, and the system can be fixed rigidly to the skull of the patient for a period of up to several weeks. Exchange of the cannula is possible within 1 minute. The system has been used in 90 cases so far, with a rate of possible infection of 1.1%.
