[Transfusion-associated acute pulmonary insufficiency: a rare, but life-threatening transfusion reaction].

Two patients developed within several hours after blood transfusion severe shortness of breath which required temporary artificial ventilation. X-ray pictures of the chest showed pulmonary edema in both patients. No cardiac causes for edema were found. Detection of granulocyte antibodies in the sera of one patient and one blood donor confirmed the suspected diagnosis of transfusion-related acute lung injury.
