Abstract:
Objective To evaluate short-term clinical outcomes of skeletonized bilateral internal mammary artery (sBIMA) in coronary artery bypass grafting (CABG). Methods The clinical data of 62 patients (54 males and 8 females with an average age of 56.8±6.0 years) undergoing isolated CABG using sBIMA in our hospital from October 2016 to May 2017 were retrospectively analyzed. The coronary graft flow, perioperative clinical outcomes and CT results were reviewed. Results All the operations were carried out under extracorporeal circulation. Anastomosis of 124 internal mammary arteries was performed and 116 great saphenous veins were used simultaneously with an average anastomosis site of 4.5±0.8 for each patient. The cardiopulmonary bypass time was 116.4±22.9 min, aortic clamping time was 83.0±18.3 min, mechanical ventilation time was 20.8±21.3 h and ICU stay was 2.7±1.7 d. The graft flow of left internal mammary artery (LIMA), right internal mammary artery (RIMA) and great saphenous vein were 28.8±12.4 mL/min, 32.8±13.8 mL/min and 41.5±21.5 mL/min, respectively. There was no significant difference in the graft flow between LIMA and RIMA (P=0.112). There was no perioperative mortality, myocardial infarction or cerebrovascular accident. Only one male patient suffered sternal complication and poor wound healing and then received debridement as well as suturing. Coronary CT angiography showed that distal anastomosis of 7 vein grafts and 5 artery grafts was demonstrated shallow and 1 vein graft was undemonstrated, suggesting occlusion. Conclusion CABG with sBIMA is a safe and reliable technique with excellent early results.
