A Case of Unicuspid Aortic Valve Stenosis Associated with Tracheomalacia

Abstract

A 64-year-old woman who underwent colectomy for colon cancer was diagnosed as having aortic stenosis and a thoracic aortic aneurysm, and underwent aortic valve replacement and ascending aortic replacement surgery. She had a unicuspid aortic valve (UAV). Reintubation after extubation was repeate because of acute respiratory failure. Obstruction of the trachea with the aortic aneurysm was noted on computed tomography. Tracheal stent placement and a tracheotomy were performed, with resolution of her respiratory failure due to tracheomalacia.
