In a retrospective review of 418 tunneled pleural catheters placed over 2 years, 91% of patients did not require any other drainage procedure. Spontaneous pleurodesis occurred in one-quarter, in whom the catheter was taken out at a median 44 days. More patients with catheters placed in the operating room achieved pleurodesis (36%). Complication rate overall was ~5%. J Thorac Onc 2011;6:762-767.
