Successful one-lung ventilation using a bronchial blocker tube for a large tracheal carcinoma resection

The informed consent was obtained from the patient. A 57-year old woman was diagnosed as a trachea adenoid cystic carcinoma. A large tumor was found in the upper tracheal under fiber bronchoscopy (FBO), which the lower edge of the tumor was about 3cm proximal to the carina and the tumor size was about 4cm, obstructing the tracheal lumen by 92%. The gap at the narrowest intraluminal point was about 0.5cm (Fig.1A, B). Abnormal FEV 1% FVC: 22.07 and PaO2: 6.5kPa were detected by pulmonary function test and arterial blood gas test on room air respectively.
