A 28-year-old female suffered from airway obstruction due to the rupture and bleeding of a tracheal vascular tumor. (A. Massive abnormal vascular hyperplasia in the right upper mediastinum. The normal mediastinum pleura was not visualized. B. The hemangioma was composed of a large number of criss-cross arteriovenous masses. C. Intraoperatively, the right intermediate bronchus was opened. Several blood clots can be seen blocking the bronchus. The blood clots in the main airway were completely removed. D. Chest X-ray after hemoptysis worsened. E. Chest X-ray at discharge.)
