Lung cancers in the residual lungs of patients who have undergone pneumonectomies are often unresectable, primarily because of the risks of overt pulmonary function losses. Percutaneous cryoablation of lung tumors is a potentially minimally invasive technique that has recently been used in the treatment of lung cancers and metastatic lung tumors. Here, we present two patients who had previously undergone pneumonectomies, in whom lung cancers in the residual lungs were treated by cryoablation. In both patients, the procedures were performed safely without any complications, such as airway bleeding, hemothoraces, or pneumothoraces. The changes in pulmonary functions after the procedures were minimal: % vital capacity (2 1% and 2 4%), and %FEV1( - 1% and + 10%) in the first and second patients, respectively. The performance statuses were maintained at zero in both patients after cryoablation. In the first patient, local control has been maintained for 4 years. In the second patient, local control was maintained for 2 years until the patient died of distant metas tases. This is, to our knowledge, the first reported case of lung cryoablation in residual lungs of patients who have previously undergone pneumonectomiespneumonectomies. Application of percutaneous cryoablation may represent a new treatment option for lung tumors in patients who have previously undergone pneumonectomies.
