The left internal mammary artery (LIMA) is a widely used conduit during coronary artery bypass graft (CABG) surgery because of its excellent long-term patency. Although large LIMA side branches are typically ligated during the surgery, the occurrence of a coronary steal phenomenon related to these side branches following surgery remains controversial. Advocates for occlusion of LIMA side branches in the setting of left anterior descending artery (LAD) ischemia indicate that anginal symptoms often improve and that objective measures of LAD ischemia frequently resolve. We present a patient with ischemia in the LAD distribution secondary to coronary steal from a large LIMA side branch that was successfully treated using the Embolization Coil-IMWCE-3-PDA5 (Cook Medical, Bjaeverskov, Denmark).
左乳内动脉（LIMA）因其出色的长期通畅性，是冠状动脉旁路移植术（CABG）中广泛使用的血管桥。尽管手术中通常会结扎LIMA的大分支，但术后与这些分支相关的冠状动脉窃血现象的发生仍存在争议。主张在左前降支（LAD）缺血情况下闭塞LIMA分支的人指出，心绞痛症状通常会改善，LAD缺血的客观指标常常会消失。我们报告一例患者，其LAD分布区缺血继发于来自LIMA一个大分支的冠状动脉窃血，该患者使用Embolization Coil-IMWCE-3-PDA5（库克医疗公司，丹麦比耶弗斯科夫）成功治疗。
