Abstract：Objective To evaluate the effect and experience of epicardial ultrasound combined with tran sit time flow measurement(TTFM) in off-pump coronary artery bypass(OPCABG).Methods Retrospectively analyzed 85 cases of patients received OPCAB and used epicardial ultrasound combined with TTFM from January to December in 2016.The patients included 46 cases of men and 39 cases of women,the age from 44 to 82 and the average age was 65.6.Nine cases adopted complete arterial revascularization (LIMA+BRA),two cases adopted complete venous revascularization ("Y" bypass-conduits),the rest cases were LIMA+SVG.The vein-bypass-con duits were anatomized proximal aorta preferentially.They were all sequential bypass conduits.The follow-up were carried out in postoperation of 1,3,6 months.Results One case showed the low flow and high PI after LIMA were anatomized to LAD.So the anastomosis were redone,then the flow and PI were satisfied.The results in rest cases were all satisfied and met the clinical standards.The hemodynamics was stable in the operation and there were not perioperative myocardial infarction and death in all cases.Also there were no MACE and aortic injury cases.There were no recurrence of angina in postoperative short-term.Conclusion Using of the epicardial ultrasound in CABG can avoid anastomosing to the atheromatous plaque and insure the short-time and long-term patency of the bypass-conduits.The epicardial ultrasound combined with TTFM can measure the flow and PI of the conduits after finished the operation,and then ensure the security of operation,it is worthy to be widely used in clinical practice.
