[Pericardial and pulmonary vascular involvement].

Over five hundred lung resections were considered, out of a series of 1570 cases of lung cancer. Histology of resected patients resulted squamous (348), adenocarcinoma (107), large cells (21) and small cells carcinoma (37). According to Mountain staging, 41% of patients were related to stage Ist, 12% to the IInd, 40.9% to the IIInd A: in such a group, a special class T3N0M0 was considered, due to the better follow-up observed in such cases. Lobectomies and minor resections were performed in 321 cases, pneumonectomies in 192. An analysis was done of differences in Histology, staging, early mortality, complications and late results after pneumonectomy which was traditional in 117 patients and required an intrapericardial section of great vessels in 68 cases: 16 patients had some pericardial resection, specific ECG disturbances, early mortality and recurrence within five years proved to be higher in the patients who had some pericardial operation: also as far as no connection was recognized with histology, the responsibility of such results can be attributed to the stage, that in those patients required a more aggressive operation.
