Abstract

Recurrent angina after coronary artery bypass grafting is rarely caused by left subclavian artery (LSCA) stenosis resulting in reduced left internal mammary artery blood flow. We present 2 cases of coronary-subclavian artery steal syndrome resulting from LSCA stenosis and their successful surgical management with left carotid to LSCA bypass. Based on the successful management described in this case report, and the limitations of other options in addressing coronary-subclavian artery steal syndrome, left carotid to LSCA bypass surgery should be considered for revascularization in patients who develop postoperative coronary-subclavian artery steal syndrome due to LSCA stenosis.

摘要

冠状动脉旁路移植术后复发性心绞痛很少由左锁骨下动脉（LSCA）狭窄导致左乳内动脉血流减少引起。我们报告2例因LSCA狭窄导致的冠状动脉-锁骨下动脉窃血综合征病例，以及通过左颈动脉至LSCA旁路移植术成功进行的手术治疗。基于本病例报告中描述的成功治疗方法，以及在处理冠状动脉-锁骨下动脉窃血综合征时其他方法的局限性，对于因LSCA狭窄而发生术后冠状动脉-锁骨下动脉窃血综合征的患者，应考虑采用左颈动脉至LSCA旁路移植手术进行血运重建。
