Coronary subclavian steal syndrome (CSSS) is an uncommon complication of coronary artery bypass graft (CABG) surgery when the left internal mammary artery (LIMA) is used in patients with underdiagnosed significant left subclavian artery stenosis (SAS). It is characterized by a retrograde blood flow from coronary to subclavian circulation through LIMA graft, causing the "steal" phenomenon and myocardial ischemia. The common presentation is stable angina years after surgery and acute presentation with ST elevation early after surgery is extremely rare. Here we present an unusual and unique presentation of CSSS in a setting of acute ST elevation myocardial infarction treated successfully with complex percutaneous intervention.
冠状动脉锁骨下动脉窃血综合征(CSSS)是冠状动脉旁路移植术(CABG)的一种罕见并发症,当在左锁骨下动脉狭窄(SAS)未得到充分诊断的患者中使用左乳内动脉(LIMA)时就会发生。其特征是血液通过LIMA移植物从冠状动脉循环逆行至锁骨下循环,导致“窃血”现象和心肌缺血。常见表现是术后数年出现稳定型心绞痛,术后早期出现ST段抬高的急性表现极为罕见。在此,我们报告一例CSSS的不寻常且独特的表现,该患者在急性ST段抬高型心肌梗死的情况下通过复杂的经皮介入治疗成功治愈。
