[Case report. Pulmonary embolism complicated by angioneurotic edema.].

Although angioneurotic oedema (AE) is a rare entity, it sometimes leads to devastating consequences. We report the case of an oro-pharyngeal angioneurotic attack following the initiation of a fibrinolysis therapy by alteplase and relay by heparin in a patient with severe acute pulmonary embolism. In view of this original case, we propose to highlight the most recent elements concerning the physiopathology of this disease.
