Cold agglutinin disease(CAD) is an autoimmune disease that occurs against erythrocyte antigens. It is usually idiopathic, but some infections can also be a trigger. CAD becomes active in the peripheral circulation at lower temperatures more easily when exposed to cold, causing hemolysis or agglutination. In this article, the management of a coronary bypass case with CA formation in intraoperative period is presented. A 46-year-old diabetic and hypertensive male patient had COVID-19 2 months ago. Cardiopulmonary bypass(CPB) was initiated with adequate heparinization, and the patient was cooled to 32°C. It was noticed that there were clots in the cardioplegia delivery line(+1°C). Agglutinations were observed in the autologous blood of the patient whose ACT values were normal. After CPB, the operation was completed without any problems and the patient was discharged on the 5th day with recovery. A diagnosis of CAD was made with the results of peripheral smear and immunologic tests. Determination of antibody concentration and thermal amplitude in the preoperative period in patients with CAD is very important. While preparing such patients for surgery, heating of room, patient, fluids, planning of normothermic CPB, and using warm cardioplegia are required. The relationship between CAD and COVID has started to take place in the literature. The patient we presented had a COVID 2 months ago, cold agglutinin may have been induced by COVID or may have arisen idiopathic. Considering that many people may have had a COVID nowadays, care should be taken especially in the perioperative period of cardiac surgery. [ABSTRACT FROM AUTHOR]
