Bradykinin-mediated angioedema (AE) is characterized by periodic subcutaneous or submucosal swelling, with the absence of urticaria and itching. It affects the face and extremities. Attacks of abdominal pain and obstruction of the upper airways are the hallmarks of disease severity. The aim of this study was to determine the factors prompting patients to turn up at the hospital emergency department (ED) in the event of an attack.
