title: Preliminary experiences with the Orbis-Sigma-System as a ventriculo-peritoneal shunt.
abstract: In the last 3 years an Orbis-Sigma system has been implanted in 40 hydrocephalic children (as a primary shunt in 28 and following another shunt system in 12). Its usefulness was tested by regular clinical examinations, head circumference measurement, ultrasonography or CT and the causes and frequency of shunt revisions. The preliminary results of a mean follow-up time of 1.4 years are discussed.
