Objective To evaluate the perioperative, short- and mid-term results of total artery bypass grafting and saphenous vein bypass grafting in three-vessel coronary heart disease patients complicated with diabetes.Methods Retrospective analysis was performed on 46 patients (a TAR group) including 36 males and 10 females with an average age of 65.1±11.3 years who underwent total artery bypass grafting in Renji Hospital affiliated to Shanghai Jiao Tong University Medical College from 2005 to 2014. A total of 46 patients with age and gender matched admitted during the same period were selected as a control group (NCR group), in which left internal mammary artery and great saphenous vein were used as grafting vessels. Preoperative, perioperative, and postoperative (1 year and 5 years) data of the two groups were analyzed.Results In terms of perioperative data, the TAR group was inferior to the NCR group in operation time, postoperative 24 h drainage volume and postoperative 24 h blood transfusion volume. However, there was no difference between the two groups in terms of perioperative mortality, ICU stay, etc. One year after surgery, there was no difference in angina pectoris recurrence, recurrent myocardial infarction or grafting vessel patency rate between the two groups. Five years after the operation, the TAR group was superior to the NCR group in angina recurrence, myocardial infarction, and grafting vessels patency rate.Conclusion For patients with three-vessel coronary heart disease complicated with diabetes, total arterial bypass grafting can achieve better mid-term effect, although it can prolong the operation time and increase the amount of drainage and blood transfusion 24 h after operation.
