Injury of the circumflex artery (Cx) during mitral valve surgery is a rare and underrecognized life-threatening complication. A retrospective analysis of patients undergoing mitral valve operations at 2 centers was conducted. Five mitral valve operations are described. After diagnosis of Cx injury, 2 patients were treated by stent implantation, 1 by coronary bypass to the Cx, and 1 by repositioning the responsible annular stitches. In another patient, the Cx injury was not treated and was diagnosed at autopsy. There were no deaths in patients whose Cx injury was promptly treated. Cx injury can be successfully managed when it is treated on time.
回旋支动脉（Cx）损伤是二尖瓣手术中一种罕见且未被充分认识到的危及生命的并发症。对 2 个中心接受二尖瓣手术的患者进行了回顾性分析。描述了 5 例二尖瓣手术。在诊断出 Cx 损伤后，2 例患者接受了支架植入治疗，1 例患者接受了 Cx 冠状动脉旁路手术，1 例患者重新定位了负责的环状缝线。另一位患者的 Cx 损伤未得到治疗，并在尸检中诊断出来。及时治疗 Cx 损伤的患者中没有死亡病例。当及时治疗时，Cx 损伤可以得到成功的处理。
