Solitary thrombus formation in the pulmonary vein stump is a rare complication after lung resection. Some case reports have described thrombus formation in the left upper pulmonary vein stump. We report a rare case of multiple thrombi formation in the left atrium and proximal pulmonary artery. A 75-year-old man developed a giant intracardiac thrombus after undergoing left upper lobectomy for lung cancer. He had received anticoagulation therapy for 5 years because of chronic atrial fibrillation. One year ago, he had undergone video-assisted thoracoscopic left upper pulmonary lobectomy for primary lung squamous cell carcinoma. Follow-up computed tomography revealed a giant thrombus located in the left atrium along with multiple thrombi in the left upper pulmonary vein stump and pulmonary artery stump. Surgery was performed because the left atrial thrombus was too large to be treated with conventional anticoagulants. All intracardiac thrombi were removed along with closure of
