Ventriculoatrial and ventriculopleural shunts (VPS) are alternatives to ventriculoperitoneal shunts for draining cerebrospinal fluid from patients with hydrocephalus. VPS has seldom been used because of the risk of respiratory insufficiency due to pneumothorax or pleural effusion. However, valves are currently available with anti-siphon devices for use with standard shunting systems to prevent the development of pleural effusion. The aim of this study was to analyze outcome after VPS in eight patients in whom we used the new valves for avoiding overdrainage of cerebrospinal fluid. ⋯ Valves newly designed to prevent overdrainage of cerebrospinal fluid give satisfactory results, such that VPS should be considered as an alternative to peritoneal drainage.
