We report a case of delayed bleeding after video-assisted thoracic surgery (VATS) that was successfully treated with transcatheter arterial embolization. An 81-year-old woman underwent a pleural biopsy via VATS for pleural dissemination of lung cancer. The postoperative course was good, but 8 days later she was hospitalized for swelling in the right axilla and was admitted to our hospital with a diagnosis of delayed postoperative hemorrhage. Gauze compression was performed, and the patient was discharged without exacerbation of hematoma. However, 4 days later, she was hospitalized for rapidly worsening swelling and pain. Chest computed tomography at the time of rebleeding showed an increase in the hematoma and extravasation in the peripheral right lateral thoracic artery. The patient was immediately treated with emergency angiography, and coil embolization was performed. After this treatment, the patient has done well and there has been no subsequent recurrence of bleeding.
