[Extended Right Pneumonectomy with Partial Resection of the Left Atrium without Cardiopulmonary Bypass].

A 62-year-woman suffered a palpitation for 1 years and was admitted to our hospital with complaints of hemosputum. Chest computed tomography(CT) revealed right hilum tumor diffusely invaded to left atrium. The patient was resected without cardiopulmonary bypass, the interatrial groove (Waterston's or Sondergaard's groove) was carefully dissected and right pneumonectomy with systematic lymph nodes dissection and partial left atrium resection were performed. The posteoperative left atrial volume decreased to half of preoperative volume (from 73 ml to 36 ml) judging from 3D-CT scan. Her postoperative course was uneventful and palpitation, disappeared postoperatively. The histlogical examinarion revealed pleomorphic carcinoma with mediastinal single lymph nodes matastasis (#7), the pathological stage was pT4N2M0. She did not receive adjuvant chemotherapy, but has had no sign of recurrence for 3 years after surgery.
