Abstract:
Objective: To preliminarily analyze the graft flow of right internal mammary artery (RIMA) in patients after coronary artery bypass grafting (CABG) using bilateral internal mammary artery (BIMA). Methods: A total of 52 patients received CABG by BIMA in our hospital from 2015-12 to 2016-07 were studied. The patients were younger than 65 years at the mean age of (56.6±6.8) years including 46 male. According to conduit grafting to left anterior descending artery (LAD), the patients were divided into 2 groups: RIMA anastomosed to LAD group, n=42 and LIMA anastomosed to LAD group, n=10. The immediate graft flow was measured by Veri Q system, surgical outcomes and graft flows were compared between 2 groups. Results: There were no operative death in all 52 patients, 1 had poor wound healing and received debridement and suturing, no one had operative complication in left 51 patients. The average LAD bridge flow in both groups were (28.7±11.5) ml/min and (31.8± 11.7) ml/min, the mean pulsation index (PI) were (2.3±0.7) and (2.0±0.4), P>0.05; the average RIMA graft flow were (28.7±11.5) ml/min and (21.1±11.0) ml/min, the mean PI were (2.3±0.7) and (2.6±1.1), P>0.05. Conclusion: Flows in RIMA-LAD graft and LIMA-LAD graft were similar; the flow of RIMA anastomosed to other target vessel was satisfactory which was an ideal graft for CABG.
