Coronary subclavian steal syndrome (CSSS) is a rare cause of angina. It occurs in patients with prior coronary artery bypass grafting and, specifically, a left internal mammary artery (LIMA) to left anterior descending artery (LAD) graft and co-existent significant subclavian artery stenosis. In this context, there is retrograde blood flow through the LIMA to LAD graft to supply the subclavian artery beyond the significant stenosis. This potentially occurs at the cost of compromising coronary artery perfusion dependent on the LIMA graft. In this review, we present a case of a middle-aged female who suffered from CSSS and review the literature for the contemporary diagnosis and management of this condition.
冠状动脉锁骨下窃血综合征（CSSS）是心绞痛的一种罕见病因。它发生于既往行冠状动脉旁路移植术的患者中，特别是左内乳动脉（LIMA）至左前降支（LAD）搭桥术，同时合并显著的锁骨下动脉狭窄。在这种情况下，通过 LIMA 至 LAD 搭桥术会有逆行血流，以供应狭窄段远端的锁骨下动脉。这可能会以牺牲依赖 LIMA 桥的冠状动脉灌注为代价。在本文中，我们报告了一例中年女性 CSSS 患者，并对该病症的现代诊断和治疗进行了文献复习。
