To improve the early and late benefits (the patency and total myocardium revascularization) of coronary artery bypass grafting, stimulate us using only bilateral internal mammary artery (BIMA) composite Lima (left internal mammary artery)-Rima (right internal mammary artery) Y graft with off-pump, here is the early evaluation.
From October 2002 to December 2005, 125 patients underwent off-pump coronary artery bypass grafting with the only composite grafts. The bilateral semi-skeletonization internal mammary artery pedicles composed the Y graft, the free Rima was anastomosed to the in situ Lima. The operation was performed off-pump and sequential anastomosis.
Four hundred and thirteen grafts for 125 patients, average number of grafts per patient was 3.3. Graft flow was measured with Transit time flowmeter during operation time. All grafts were patent during operation. There was no death perioperative period.
Off-pump coronary artery bypass grafting with only bilateral internal mammary artery composite Lima-Rima Y graft is secure and feasible. The technique could achieve total arterial myocardium revascularization and avoiding any procedure on the ascending aorta.
为提高冠状动脉搭桥术的早期和远期效益（通畅率和心肌完全血运重建），激励我们采用仅使用双侧乳内动脉（BIMA）的复合利马（左乳内动脉）-里马（右乳内动脉）Y形移植物在非体外循环下进行手术，以下是早期评估。
2002年10月至2005年12月，125例患者接受了仅使用复合移植物的非体外循环冠状动脉搭桥术。双侧半骨骼化乳内动脉蒂构成Y形移植物，游离的里马与原位利马进行吻合。手术在非体外循环下进行并采用序贯吻合。
125例患者共植入413支移植物，平均每位患者植入3.3支。术中使用 Transit time 血流仪测量移植物血流。所有移植物在术中均通畅。围手术期无死亡病例。
仅使用双侧乳内动脉复合利马-里马Y形移植物进行非体外循环冠状动脉搭桥术安全可行。该技术可实现心肌完全动脉化血运重建，且避免了升主动脉上的任何操作。
