We report a case of a 52-year-old man with severe coronary artery and graft spasm after triple-vessel off-pump coronary artery bypass grafting. Emergent coronary angiography was performed to identify the location and severity of the spasm. Intracoronary injections of several vasodilators failed to relieve the spasm. Observational treatments including intra-aortic balloon pump and inotropic drugs to increase coronary flow were performed until the spasm resolved. The patient recovered and was discharged. A follow-up coronary angiography revealed patent native coronary artery and bypass grafts without evidence of residual spasm.
我们报告一例52岁男性患者，在非体外循环下进行三支血管冠状动脉旁路移植术后出现严重冠状动脉和移植血管痉挛。进行了急诊冠状动脉造影以确定痉挛的部位和严重程度。冠状动脉内注射多种血管扩张剂未能缓解痉挛。采取了包括主动脉内球囊反搏和使用正性肌力药物以增加冠状动脉血流的观察性治疗措施，直至痉挛缓解。患者康复并出院。随访冠状动脉造影显示，自身冠状动脉和旁路移植血管通畅，无残余痉挛迹象。
