A 65-year-old man with unstable angina was transferred to our department for coronary artery bypass grafting (CABG). Preoperative computed tomography indicated a large thrombosis in the left coronary cusp (LCC). CABG concomitant thrombectomy was performed under cardiopulmonary bypass using unfractionated heparin. Although the LCC was filled with a large thrombus, the left coronary artery ostium was not obstructed. The platelet count decreased by 68%, 12 days after starting heparin in the previous hospital. There is a high probability that this patient had HIT which was not recognized before surgery.
