[Sleeve pulmonary arterial resection for bronchogenic carcinoma].

Two cases of bronchogenic carcinoma undergone left upper lobectomy (R 3) with bronchoplasty and sleeve pulmonary arterial resection via mid-sternotomy were reported. Both cases were squamous cell carcinoma originated in the orifice of the left upper lobe. Case 1 was stage IIIB (T2N3M0) bronchogenic carcinoma, its postoperative course was uneventful and died of distant lymphatic metastasis thirty-three months after operation. Case 2 was stage II (T2N1M0) bronchogenic carcinoma and its postoperative management was laborious because of hard expectoration of the sputum but is doing well fifteen months after operation. In order to preserve adequate pulmonary function and to maintain reasonable quality of life (QOL) for the patients with impaired pulmonary function, this angioplastic procedure seems to be acceptable. It is still under discussion to perform this procedure for the patients who would be able to withstand undergoing pneumonectomy, therefore we adopt this method only for every patient for whom it is difficult to maintain desirable QOL after pneumonectomy. Namely, for the patient whose predicted one second forced expiratory volume (FEV1.0) after pneumonectomy is less than 900 ml/m2, we'll be likely to try this angioplastic procedure at first.
