Novel complications of the tunnelled indwelling pleural catheter.

Tunnelled indwelling pleural catheters (TIPC) are a modality of treatment for malignant pleural effusions. Though relatively easy, safe and efficacious, they are associated with a small risk of complications. We describe newer complications of the TIPC including the retention of the polyester plug and the blockage of the catheter with thick organised material consisting of malignant cells taking the shape of the catheter.
