摘要
目的总结非体外循环下采用双侧乳内动脉Y型桥进行完全心肌血运重建的冠状动脉旁路移植手术125例的近期疗效。方法2002年10月至2005年12月,完成125例不停跳非体外循环下双侧乳内动脉Y型桥的冠状动脉旁路移植手术,术中采用带蒂半骨骼化的方法分别取材左、右侧的乳内动脉,将左、右乳内动脉端侧吻合成Y型桥;在非体外循环下,应用序贯吻合的方法进行冠状动脉搭桥手术。结果全组125例患者共搭桥413支,平均搭桥支数3.3支/例。术中流量测定桥血管均通畅。全组患者无围手术期死亡。结论非体外循环下双乳内动脉Y型桥的冠状动脉旁路移植手术是安全、有效的方法,可以实现全动脉化的完全心肌血运重建,又避免手术中对升主动脉的操作,近期效果满意。
Objective 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. Methods From October 2002 to December 2005 , 125 patients underwent off-pump coronary artery bypass grafting with the only composite grafts. The bilateral semiskeletonization 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. Results 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. Conclusion 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 revascnlarization and avoiding any procedure on the ascending aorta.
