Pulmonary arterial balloon occlusion during video-assisted thoracoscopic surgery for reduction of the risk of massive hemorrhage

Transient occlusion procedure with a catheter for peripheral pulmonary artery damage caused by percutaneous drainage for lung abscess

The patient was a 78-year-old man who had liver and lung abscesses. Percutaneous drainage was performed for the lung abscess. While the drainage was successful for both abscesses, a drainage tube injured the peripheral pulmonary artery, causing hemorrhage and hemosputum. An occlusion technique for the pulmonary basal artery using a wedged barman catheter stopped the bleeding, resulting in a successful outcome.
