ABSTRACT
TPC is a catheter inserted into the pleural space for chronic drainage of pleural eusions. Available from several manufacturers, they are typically a 15.5-16 Fr, 40-60 cm silicone catheter with multiple fenestrations along its distal aspect. e external tip of the catheter contains a valve that
prevents leak of air or uid from the pleural space when the catheter is not connected to an external drainage system (Figure 45.1). e catheter is tunneled subcutaneously for several centimeters and a polyester cu is embedded under the skin during insertion. e textured cu located midway along the catheter acts as a nidus for tissue ingrowth and healing, creating a seal along the tunnel tract.
