Five patients had undergone off-pump coronary artery bypass grafting (CABG) as redo CABG via the left thoracotomy for the lesions of the left circumflex coronary arteries. In all patients, the internal thoracic artery (ITA) grafts to the LAD were well patent and acting significantly important in coronary circulation, however, ischemia due to the lesion of the LCX was significant. The saphenous vein grafts or the radial artery grafts were used as the materials of the grafts. The proximal ends of these grafts were anastomosed to the descending aorta. The procedures were completed successfully in all the patients and the excellent patency was shown angiographycally even in the long-term period after the surgery. Necessity of graft surgery only for the LCX lesion would be a rare occasion for a surgeon; however, these results suggest that the procedure is simple and less risky, which would encourage the surgeon to perform it in clinical situation.
五名患者因左旋支冠状动脉病变，经左胸切口行非体外循环冠状动脉旁路移植术（CABG）作为再次冠状动脉旁路移植术。在所有患者中，左前降支的胸廓内动脉（ITA）移植物通畅良好，在冠状动脉循环中发挥着重要作用，然而，由于左旋支病变导致的缺血明显。大隐静脉移植物或桡动脉移植物用作移植物材料。这些移植物的近端与降主动脉吻合。所有患者手术均成功完成，即使在术后长期，血管造影显示移植物通畅良好。仅针对左旋支病变进行移植手术对外科医生来说是罕见情况；然而，这些结果表明该手术简单且风险较小，这将鼓励外科医生在临床情况下开展该手术。
