One case of hereditary angioneurotic laryngeal edema / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

Hereditary angioneurotic laryngeal edema (HALE) is an autosomal dominant hereditary disease in which there is a decrease or defect in the C1 inhibitor (C1-INH). The pathophysiology of HALE is characterized by recurrent spontaneous episodes of transient edema of the laryngeal mucose and submucosal tissue with remission at irregular. Patients may die because of a life-threatening acute upper airway obstruction caused by laryngeal edema. HALE was diagnosed on the clinical symptoms, family history, and markedly decreased serum C1-INH activity and C1-INH protein.
