Abstract

Introduction

The aim of the study was to describe the authors’ experiences with the adjustable gravitational proGAV shunt system in treating infants’ hydrocephalus.

Patients and methods

The proGAV was implanted in 29 infants (11 boys and18 girls, median age 9 months) with hydrocephalus of various origins between January 2010 and June 2014. The opening pressure was chosen based on the intraventricular pressure which was measured during operation, and a gravitational unit with a fixed opening pressure (15 cm H2O) was selected.

Result

Regular clinical follow up ranged from 6 to 36 months, with a mean follow-up time of 15.7 ± 7.9 months. Five of these patients (17.2 %) underwent shunt revision because of malfunction, including two infections (6.9 %), two shunt exposed (6.9 %), and one proximal catheter occlusion (3.4 %). For readjustment in 10 infants, the opening pressure was changed at least once during the follow-up period.

Conclusion

The proGAV is efficacious in the treatment of hydrocephalus in infants. This individual selection of the opening pressures makes it probable that a better match of chosen opening pressure and actual hydraulic requirements of the patient might occur.
