title: Thoracic aortic aneurysm causing acute bronchospasm.
abstract: Acute respiratory failure presenting as intractable bronchospasm was caused by tracheal obstruction due to an aneurysm of the thoracic aorta. Atropine was used successfully as a bronchodilating agent, as conventional therapy failed. The diagnosis was established by fiberoptic bronchoscopy.
