Abstract:
Objective To review the outcome of coronary artery bypass graft (CABG) using left internal thoracic artery grafts in the patients aged over 70 years old.Methods Two hundred and eighty-eight patients aged over 70 years old from January 2009 to January 2014 who underwent CABG were selected.All of the patients were divided into two groups on base of the graft:control group:only saphenous vein graft was used in 138 cases; observation group:the left internal thoracic artery to the left anterior descending artery was used in 150 cases,which also included total arterial grafting,facilitated by the use of the radial artery,right gastroepiploic artery was operated in 7 cases,beside these artery grafts,saphenous vein graft was used to anastomosis with other vessels.Results Operative mortality was 2.9％ (4/138) in control group and 2.0％ (3/150) in observation group,and there was no significance (P ＞ 0.05).The volume of blood drainage was larger in observation group [(796.2 ± 382.4) ml] than that in control group [(512.8 ± 387.5) ml],and there was significant difference (P ＜ 0.05).At the same time,there was no significant difference in the incidence rate of second thoractomy,malignant arrhythmia,stroke,poor wound healing,and usage of intraaortic balloon counterpulsation between two groups (P ＞ 0.05).Conclusion It does not increase the mortality and incidence of serious complications using the left internal thoracic artery to the left anterior descending artery in the patients aged over 70 years old during CABG.
