Total arterialized coronary artery bypass grafting: short-and mid-term clinical outcomes / 中华胸心血管外科杂志

ABSTRACT

Objective:To evaluate the safety of total artery coronary artery bypass grafting(CABG) in patients with coronary heart disease and the short- and mid-term clinical outcomes.Methods:A retrospective analysis of the clinical data of 100 patients who underwent CABG treatment in the First Affiliated Hospital of Guangxi Medical University from January 2016 to July 2021. Of these, 50 patients were selected for comparison(TACR) with the left internal thoracic artery and radial artery(RA) as grafts. However, the left internal thoracic artery and the great saphenous vein were used as grafts in other 50 patients were selected as controls(NCR). The clinical data of preoperative, perioperative, and postoperative(3 months, 6 months, 1 year and 5 years) for two groups were compared.Results:In the perioperative period, TACR group was inferior to the control in both operation time and 24 h postoperative drainage. But the peak value of hypersensitive troponin T was lower than that of NCR. There was no significant difference between the two groups in terms of mechanical ventilation time and perioperative mortality. There was no significant difference between the two groups in terms of left ventricular ejection fraction(LVEF), recurrent angina, left ventricular end-diastolic diameter and recurrent myocardial infarction at 3 and 6 months after operation. LVEF in TACR was better than that in NCR at 1 year and 5 years postoperatively.Conclusion:The clinical effect of CABG with RA as bridge vessel carried out in our center is obvious. TACR is safe and feasible due to its good mid-term efficacy and is not likely to cause postoperative complications.
