After treatment,according Grillo's response criteria,69% of the pts had good results,15% had satisfactory results and 15% had therapeutic failure.Conclusions: Interventional bronchoscopy plays definitive role in the treatment of TS,either as the primary choice or in the resolution of post-surgical complications.
