Autoblood plus OK432 pleurodesis with open drainage for persistent air leak after lobectomy.

Prolonged air leak with dead space after lobectomy was successfully treated with autoblood plus OK432 pleurodesis in 10 patients. We tried this method for the purpose of (1) reduction of dead space and (2) effective chemical sclerosis. This easy method was associated with acceptable side effects and should be considered as an option for the treatment of prolonged air leak after lobectomy, especially with dead space.
