[Acute Aortic Dissection Complicated by IgA Deficiency]

Immunoglobulin A (IgA) deficiency is the most common type of primary immunodeficiency. When a patient receives a blood product transfusion, anti-IgA antibodies are formed. Second transfusion may sometimes cause an anaphylactic reaction, thus caution is necessary. Reported here is a case of Stanford type A acute aortic dissection performed in the patient with IgA deficiency with a history of blood transfusion. Red blood cells and platelet were washed and prepared, and flesh frozen plasma from IgA deficient donors was obtained. Thereafter, the surgery was safely performed.
