Objective To introduce the strategies of coronary artery bypass grafting (CABG) surgery for elderly patients over 65 years old. Methods Three hundred and ninety four elderly patients were retrospectively studied, 92.4% of whom were complicated with other diseases. Off-pump CABG (OPCAB) was used in 248 cases (62.4%). For the remaining patients with severely compromised cardiac function or small target vessel with diffuse lesion, conventional CABG (CCABG) was selected. Left internal mammary artery (LIMA) was harvested with extrapleural harvesting technique and grafted to left anterior descending artery (LAD) in 96.2% of patients. Saphenous vein or radial artery was utilized for the other coronary arteries. Transit-time flowmeter (TTFM) was utilized to make sure that grafts were patent with satisfactory blood flow. Perioperative blood sugar level was controlled at 6-10mmol/L by insulin. Results Grafts of per patient were 3.14?0.55 for on-pump CABG and 2.40?0.81 for OPCAB. Three patients died resulting in a mortality of 0.76%. The incidence of complication was 2.28%. The rest recovered uneventfully. Intubation time of OPCAB was significantly shorter than that of CCABG. Patients were discharged within 11.84?4.95 days after operation. Conclusion Good short-term result, namely low incidence of mortality and complication, could be obtained in elderly patients over than 65 years old undertaking CABG.
