title: Hereditary angioedema: A rare presentation after anterior cervical discectomy and fusion.
abstract: Hereditary angioedema is an autosomal dominant disorder following a genetic defect of C1 inhibitor gene on chromosome 11. This rare condition presents itself as a recurrent attack of submucosal swelling mostly involving skin, gastrointestinal tract and upper respiratory airway and exacerbates with any physical and emotional stress. Prompt diagnosis and prevention of an acute attack with early recognition and effective treatment can protect the patient from potential laryngeal edema and fatality.
