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.

肝素诱导的血小板减少症导致的天然主动脉瓣血栓形成
一名患有不稳定型心绞痛的 65 岁男性被转移到我科进行冠状动脉旁路移植术 (CABG)。术前计算机断层扫描显示左冠状动脉尖部(LCC)有大血栓形成。在体外循环下使用普通肝素进行 CABG 伴随的血栓切除术。虽然 LCC 充满了大血栓,但左冠状动脉口没有阻塞。在之前的医院开始使用肝素后 12 天,血小板计数下降了 68%。该患者很可能患有在手术前未被发现的 HIT。
