Early clinical efficacy of left internal thoracic artery plus radial artery in total arterialized coronary artery bypass grafting
Objective To investigate the early clinical efficacy of left internal thoracic artery(LITA)plus radial artery(RA)in total arterialized coronary artery bypass grafting(TA-CABG).Methods The clinical data of 105 patients who underwent total TA-CABG during Jan.2020 and Jun.2022 in the Department of Cardiovascular Surgery of Shan-dong Provincial Qianfoshan Hospital were retrospectively analyzed,including 59 who underwent off-pump coronary ar-tery bypass grafting(OPCAB)and 46 who underwent on-pump coronary artery bypass grafting(ONCAB).Preopera-tive data,intraoperative graft acquisition and anastomosis methods,postoperative complications and management meas-ures were included.Computed tomography angiography(CTA)was conducted in all patients 12 months after surgery to evaluate the graft patency rate and incidence of adverse cardiovascular events.Results The operation time of ONCAB group was longer than that of OPCAB group,while the postoperative hospital stay was shorter,with statistically signifi-cant difference(P=0.006).However,there were no statistically significant differences in the number of anastomosis,flow in grafts,postoperative mechanical ventilation time,24 h postoperative drainage,arrhythmia,perioperative myo-cardial infarction,incision infection and forearm complications(P＞0.05).No death or postoperative cerebrovascular events occurred in either groups.Conclusion LITA plus RA yields satisfactory early clinical outcomes in TA-CABG.ONCAB group needs shorter hospital stay than OPCAB group.Protection of radial nerve branch is important when RA is obtained.Intraoperative and postoperative antispasmodic therapy is essential.
