Simple revision of the Denver peritoneovenous shunt with nonfunction from inflow occlusion.

Occlusion of the Denver peritoneovenous shunt can occur when fibrinous debris block the inflow tubing or valve chamber. In this situation, revision is simplified by replacing only the valve chamber and inflow tubing, without requiring exposure of the central vein or the peritoneum. The outflow tubings are then joined over a Teflon adapter.
