Abstract:
Objective To summarize the clinical experience of off-pump coronary artery bypass grafting (OPCABG) for treating high risk coronary artery disease (CAD,SinoSCORE ≥ 6 points),and to evaluate its safety and efficacy.Methods The clinical data of 73 patients with high risk coronary artery disease treated through OPCABG (high risk group)in our center from April 2012 to December 2015 were retrospectively analyzed and compared with those of other low or moderate risk 78 patients treated through OPCABG (SinoSCORE＜ 6 points,low or moderate risk group) at the same period.Results All operations in the high risk group were successfully performed.Compared with the low or moderate risk group,the rate of using left internal mammary artery grafts in the high risk group was reduced significantly (P＜0.05),the operation time,postoperative ventilator support time,postoperative intensive care unit stay time and postoperative hospitalization time were prolonged significantly (P＜0.05),the rate of using intraaortic balloon pump support was increased significantly (P＜0.05),and the occurrence rate of postoperative severe complications was also increased significantly (P＜0.05).Sixty-nine cases were postoperatively followed up for (18.3±8.6) months.During the following-up period,2 cases died.11 branches of internal mammary artery grafts patency (11/11) and 38 branches of great saphenous vein grafts patency (38/43) were confirmed in 18 cases by coronary artery computer tomography angiography or coronary angiography.One cases was performed the PCI therapy due to angina relapse,and other cases had no angina symptoms with good life quality.Conclusion OPCABG is a relatively minimally invasive and safe operative mode.Strengthening perioperative management can reduce the operation risk and achieves good short or middle term efficacy in the patients with high risk CAD.
