We report the case of a 53-year-old white man who began complaining of dyspnoea and angina 19 months after coronary artery bypass graft surgery. Coronary angiography revealed the presence of a long and critical stenosis in the native left anterior descending coronary artery, shortly after distal anastomosis of the left internal mammary artery. After failed predilatations with standard or cutting balloons, we successfully used the rotablator system, which allowed us to implant a bare-metal stent in the native left anterior descending coronary artery. However, stent deployment caused long linear graft dissection, which was reduced by drug-eluting stent implantation in the proximal and distal segments of the left internal mammary artery.
我们报告了一例53岁白人男性病例，该患者在冠状动脉搭桥手术后19个月开始出现呼吸困难和心绞痛。冠状动脉造影显示，在左乳内动脉远端吻合术后不久，其自身左前降支冠状动脉存在长段严重狭窄。在用标准球囊或切割球囊预扩张失败后，我们成功使用了旋磨系统，这使我们能够在自身左前降支冠状动脉中植入一枚裸金属支架。然而，支架置入导致了长线性移植物夹层形成，通过在左乳内动脉近端和远端节段植入药物洗脱支架，夹层得到了减轻。
