Lung Cancer Surgery in Partial Anomalous Pulmonary Venous Connection Patients.

We report pulmonary resections for lung cancers in 2 patients with partial anomalous pulmonary venous connection (PAPVC) identified preoperatively. In case 1, right upper lobectomy was performed as the definitive operation for both lung cancer and PAPVC in the same lobe. In case 2, because lung cancer and PAPVC existed in different lobes, cardiac catheterization was performed to evaluate the need for correction of the PAPVC. Then, left lower lobectomy was safely performed without correcting the PAPVC located in the left upper lobe. The treatment plan for patients with PAPVC who require pulmonary resection should be carefully considered.
