Cardiopulmonary Bypass Surgery?Cold Alert!

ABSTRACT

The term 揷old agglutinin (CA)� refers to a group of disorders caused by anti?erythrocyte autoantibodies that preferentially bind RBCs at cold temperatures (4癈�癈). CAs contribute to 10 to 15% of autoimmune hemolytic anemia. We report a case of CAs diagnosed intraoperatively during emergency mitral valve replacement.
