[Off-pump coronary artery bypass grafting with only bilateral internal mammary artery composite Lima-Rima Y graft].
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 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.


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.


CONCLUSIONS
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.
