title: [Severe oropharyngeal angioedema caused by ACE inhibitor. A case report].
abstract: Inhibitors of angiotensin converting enzyme (ACE) are suspected of inducing angioedemas in up to 0.2% of all patients. These angioedemas are mainly localized in the upper airways and therefore can cause severe airway obstruction and even death due to suffocation. We report the case of a 64-year-old man, who underwent emergency tracheotomy because of severe angioedema of the larynx, which was refractory to pharmacological treatment. We conclude that patients with ACE inhibitor-induced angioedemas should be observed by monitoring in an intensive care unit to ensure the possibility of early intubation, because conventional antiallergic-antiedematous therapy by histamine-receptor antagonists and corticosteroids is an insufficient, unreliable form of therapy in severe cases. Especially otolaryngologists should know about this uncommon potentially life-threatening side-effect of ACE inhibitors.
