[Progredient dyspnea and poor drainage in a peritoneal dialysis patient - case 2/2012]

Abstract

History and admission findings: We report on a peritoneal dialysis patients who presented with dyspnea, poor drainage and weight gain.

Investigations: A chest x-ray showed a large pleural effusion on the right side. Thoracocentesis revealed a clear protein-devoid fluid with a glucose concentration greater than that of plasma. By intraperitoneal administration of toluidine blue, a pleuroperitoneal leakage was proven.

Diagnosis, treatment and course: The patient underwent video-assisted thoracoscopy revealing a total of four spots of pleuroperitoneal leakage on the diaphragm after intraperitoneal administration of toluidine blue. Closure was attempted with the aid of a prolene patch which was stiched onto the diaphragm inducing adhesion to the lung. After three months bridging with hemodialysis, the peritoneal dialysis was commenced again without a recurrence of the leakage.

Conclusions: Pleuroperitoneal leakage can occur during the course of peritoneal dialysis treatment leading to hydrothorax. Video-assisted thoracoscopy and patching of the diaphragm with a prolene mesh can be used to treat these patients.
