title: [Experiences of cardiopulmonary bypass in the treatment of locally advanced pulmonary malignant tumors].
abstract: OBJECTIVE
  Cardiopulmonary bypass (CPB) in the treatment of locally advanced pulmonary malignant tumors invaded heart or great vessels was not well underwent. The aim of this study is to report the results of these cases with locally advanced pulmonary malignant tumor which were completely resected under CPB in our hospital.
  
  
  METHODS

  RESULTS
  There was no operative death in this series. CPB was smooth, and heart automatically rebeated in the 4 patients. All the 4 patients were discharged in 3 weeks. One patient dead of heart failure at 13 months after operation, one case dead of distant tumor metastasis at 22 months after operation.
