A case of postoperative airway obstruction by Quincke edema

: A 42-year-old female was scheduled for removal of brain tumor under general anesthesia with nitrous oxide, oxygen and isoflurane. Two days after operation, airway obstruction by increased swelling around the neck was observed. The first neck X-ray films and CT-scans after operation were not indicative of the hematoma or cyst but suggestive of the neurovascular edema (Quincke). It is necessary not to overlook postoperative airway obstruction by Quincke's edema.
