Abstract

AbstractPartial anomalous pulmonary venous return (PAPVR) is a rare congenital malformation where the pulmonary vein partially refluxes into the venous system. Here, we present the first robotic‐assisted right S3 segmentectomy in a 70‐year‐old male with early‐stage lung cancer and PAPVR in the right upper pulmonary vein. The patient, with suspected primary lung cancer (11 mm diameter, pure solid appearance in right S3 segment), exhibited clinical stage T1bN0M0 stage IA2. Preoperative computed tomography revealed severe lung emphysema, and right V1–3 returned directly to the superior vena cava. However, no signs of right‐sided heart failure were observed, and echocardiogram was normal with a pulmonary‐to‐systemic blood flow ratio of 1.4. Successful robot‐assisted right S3 segmentectomy with hilar nodal dissection was performed, and the patient was discharged on the sixth postoperative day without complications. One year postoperatively, there has been no recurrence of lung cancer or respiratory/right‐sided heart failure symptoms.
