Aneurysms of the thoracic aorta commonly press upon the trachea or bronchi with resultant respiratory difficulty. Acute asphyxiation as the cause of death in patients with such aneurysms is rare. The present report describes a patient who died of acute asphyxia when an aortic aneurysm suddenly obstructed the tracheal lumen. This occlusion was observed bronchoscopically, yet at necropsy the tracheal lumen, though narrowed, was not occluded, suggesting that the tracheal obstruction during life was due to dynamic dilatation of the aneurysmal sac. An incidental finding was the presence of three smaller aneurysms of the thoracic aorta of syphilitic origin.
