Minimally invasive coronary artery bypass grafting single-center experience in 50 patients with multi-vessel lesion / 中华胸心血管外科杂志

ABSTRACT

Objective To compare the perioperative outcomes between patients who underwent multivessel off-pump coronary artery bypass graft(OPCABG) via single left intercoastal space and sternotomy,and to explore the perioperative outcomes and technigues about minimally coronary artery bypass grafting with multi-vessel lesion.Methods From January 2017 to July 2018,100 patients were recruited using both left internal mammary artery and vein graft.They were divided into minimal invasive coronary artery bypass grafting(MICS) group and control group.Perioperative outcomes were analyzed and surgical techniques were summarized.Results There was no statistical difference in preoperative profiles,mean grafts and postoperative complications(P ＞0.05).Compared with control group,MICS group had statistical benefits in length of operation incision [(8.2 ± 1.2) cm vs.(25.3 ± 3.5) cm,P =0.000],i ntraoperative washed blood loss [(301 ± 188) ml vs.(444 ± 331) ml,P =0.01],postoperative ventilation duration [(16.18 ± 5.90) h vs.(19.60 ± 3.92) h,P =0.001] and length of ICU stay [(19.19±6.85)hvs.(23.44±4.64)h,P=0.001].Conclusion There is a learning process for surgeons to perform minimal invasive OPCABG via single left intercoastal space.Surgery is feasible for patients with multiple coronary lesions.Mid and long term following up need to be studied.
