Complete resection of primary pulmonary malignancy extending into the left atrium via the left pulmonary vein using cardiopulmonary bypass and single incision: A case series.

If the best treatment for a patient with a primary pulmonary tumor extending into the left atrium via the left pulmonary vein is surgical resection, it is necessary to determine the appropriate approach, that is, whether cardiopulmonary bypass (CPB) or complete resection, would be more suitable. Lung resections under CPB are rarely performed because of the unpredictable prognosis. We report two successful cases of safe and rapid complete resection of primary pulmonary malignancy extending into the left atrium with the support of CPB via median sternotomy. Our experiences support the application of CPB in extended left pulmonary resections to achieve complete resection.
