Abstract
We experienced a patient who had specific autoantibodies, which made blood transfusion difficult during percutaneous coronary intervention (PCI) for angina pectoris. A 69-year-old male had been undergoing maintenance hemodialysis for chronic renal failure due to chronic nephritis. As anginal attack frequently developed during hemodialysis, cardiac catheterization and PCI were scheduled for further examination. Preoperative examination showed severe anemia. Therefore, a cross match test was performed, considering the necessity of blood transfusion during PCI. However, aggregation was observed in all of the same type stored blood products. Thus, adequate blood products could not be obtained. The further examinations revealed anti-C+anti-e+autoantibodies without blood type specificity in the patient's serum. Some patients undergoing chronic hemodialysis have a history of blood transfusion for renal anemia, and the incidence of ischemic heart desease is high. Blood transfusion is sometimes required during PCI. We consider that autoantibodies are an important problem in the treatment of ischemic heart disease in patients undergoing maintenance hemodialysis.
