    Abstract:
    INTRODUCTION: 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. MATERIAL AND METHOD: Nine VPS procedures were performed in eight hydrocephalic patients between 1988 and 2000. We used differential pressure valves in eight procedures and a flow regulator valve in one. The externally adjustable Sophy valve was used in six cases. The indication for VPS was peritoneal adhesions in four cases, persistent ascites in two, ventriculoatrial valve obstruction in one, and infection of the peritoneal shunt (peritonitis) in one. The ninth case involved replacement of a previously obstructed valve. RESULTS: After a follow-up period of 22 months all shunts were functioning well and the only patient with symptoms of hydrocephalus was the one who required valve replacement at six months. No surgical morbidity or mortality was observed, and only one patient developed transitory signs of excessive cerebrospinal fluid drainage, which was corrected by regulating the magnetic valve gradient. The death of one patient 36 months after surgery was unrelated to pleural drainage. CONCLUSIONS: Valves newly designed to prevent overdrainage of cerebrospinal fluid give satisfactory results, such that VPS should be considered as an alternative to peritoneal drainage.
