[Anesthetic considerations for a patient with hereditary angioedema - A clinical case].

Hereditary angioedema (HAE), with an estimated prevalence of 1:50 000, is a rare but potentially fatal disease. It may present with recurrent systemic edema of the subcutaneous tissue and mucous membranes. Patients with HAE are at increased risk for clinical worsening with surgical stress, and may develop respiratory distress syndrome due to impaired airway and hemodynamic instability. The perioperative management of these patients requires specific interventions. We present a clinical case of a woman, 50 years old, with HAE type II scheduled for ureteral stent placement via endoscopic approach.
