For long-term patency, a left internal mammary artery (LIMA) graft is considered the gold standard for left anterior descending artery (LAD) revascularization. Subsequent occlusion of a LIMA graft may be related to atherosclerosis, narrowing at anastomotic locations, fixed torsions within the graft, straight tubular stenosis, dissection, or vasospasm. Late thrombotic occlusion of a LIMA, however, is rare, and the cause is not known, though case reports can be found in the literature. The present case is a description of the successful revascularization via percutaneous intervention of an ostial LIMA thrombotic occlusion occurring 5 years after bypass surgery in a 71-year old patient diagnosed with acute coronary syndrome.
为实现长期通畅，左乳内动脉（LIMA）移植被认为是左前降支动脉（LAD）血运重建的金标准。LIMA移植血管随后的闭塞可能与动脉粥样硬化、吻合部位狭窄、移植血管内固定扭转、直管狭窄、夹层或血管痉挛有关。然而，LIMA晚期血栓形成性闭塞很少见，其原因尚不清楚，尽管文献中有病例报告。本病例描述了一名71岁诊断为急性冠状动脉综合征的患者在搭桥手术后5年经皮介入成功治疗开口处LIMA血栓形成性闭塞实现血运重建的情况。
