RÉSUMÉ
The saphenous vein has been one of the most commonly used vascular materials for coronary artery bypass grafting(CABG), but the low long-term patency of the vein grafts limits the surgical benefits of CABG. The traditional method of saphenous vein harvesting is more damaging to the venous structures, which has led to the development of no-touch saphenous vein harvesting techniques. In this paper, we review the clinical progress of no-touch saphenous vein in CABG and the potential mechanisms of this technique, to improve the patency of vein grafts by analyzing the latest literature and research progress at the domestic and international level.

@#Objective To investigate the surgical methods and efficacy of myocardial infarction combined with ventricular septal perforation. Methods The clinical data of 60 patients with myocardial infarction combined with ventricular septal perforation admitted to the Department of Cardiac Surgery, Beijing Anzhen Hospital, Capital Medical University, from 2009 to 2018 were retrospectively analyzed. There were 39 males and 21 females, aged 63.3±8.3 years. Results Among the 60 patients, 43 (71.7%) patients were perforated in the apex, 11 (18.3%) in the posterior septum and 6 (10.0%) in the anterior septum. There were 24 (40.0%) patients of single coronary artery disease. Fourteen (23.3%) patients received intra-aortic balloon counterpulsation before surgery. The waiting time from ventricular septal perforation to surgery was 48.3 (3-217) d. All patients underwent ventricular septal perforation repair, among whom 53 (88.3%) patients received ventricular aneurysm closure or resection, and 49 (81.7%) patients received coronary artery bypass graft with an average of 2 distal anastomoses during the same period. Perioperative complications in the hospital included 8 (13.3%) deaths, 8 (13.3%) heart failure, 5 (8.3%) ventricular fibrillation, 3 (5.0%) pericardial tamponade, and 11 (18.3%) secondary thoracotomy and 11 (18.3%) residual shunt. Except for 8 patients who died in the hospital, the other 52 cured and discharged patients were followed up. The median follow-up time was 4.9 years. The 2-year and 5-year survival rate of the patients was 95.8%, and the 8-year survival rate was 89.0%. Major adverse cardiovascular events incidence was 19.2%, including 3 (5.8%) deaths, 5 (9.6%) heart failure, 2 (3.8%) myocardial infarction, and 4 (7.7%) cerebrovascular events. Conclusion For patients with ventricular septal perforation after myocardial infarction, surgery is an effective treatment method. Although the perioperative mortality rate is high, satisfactory long-term results can be achieved by carefully choosing the operation timing and methods.

Objective:To explore the clinical characteristics and outcomes of patients with myocardial infarction(MI) accompanied by ventricular septal rupture(VSR) at anterior versus inferior septum.Methods:Sixty patients with MI and VSR who had been treated by surgery between January 2009 and December 2018 were selected for a retrospective study, and allocated into either anterior septal group(AS group, n=43) or inferior septal group(IS group, n=17) based on the VSR site. The primary outcomes included major adverse cardiovascular events(MACCEs), cardiac death, MI, heart failure(HF), stroke and revascularization, with a median follow-up of 4.94 years.Results:There were 8 cases died in the perioperation, including 6 patients in the AS group, 1 case for gastrointestinal bleeding after using the extracorporeal membrane lung, 2 cases for low cardiac output after the second thoracotomy exploration and 3 for postoperative pulmonary infection. While in the IS group 2 patients died, 1 for low cardiac output after the second thoracotomy exploration and 1 for postoperative heart failure. Compared with those in IS group, patients of AS group were more likely to be composed of male patients(44.2% vs 11.8%, P=0.019), with low left ventricular ejection fraction(0.47±0.09 vs 0.56±0.06, P=0.001), shorter interval from MI to operation[(52.9±35.3)days vs(79.6±65.1)days, P=0.045], shorter CPB time[(137.9±48.6)min vs(169.9±42.3)min, P=0.024], shorter cross-clamp time[(82.4±32.1)min vs(107.0±30.4)min, P=0.011], and lower postoperative LVEDD[(49.1±5.7)mm vs.(52.9±4.8)mm, P=0.029]. There was no difference in perioperative complications between the two groups(including in hospital death, HF, ventricular fibrillation, pericardial tamponade and secondary thoracotomy). Additionally, long-term follow-up showes that there was also no difference in MACCEs, death, MI, HF, stroke and revascularization between the two groups( P>0.05). Conclusion:The perioperative risk and outcomes of surgery for MI patients with AS or IS are similar.

Objective To investigate the outcomes of coronary artery bypass grafting(CABG) in insulin-treated diabetes mellitus(DM) patients with coronary artery disease(CAD) (age≤45 years old),and analyze the risk factors of major adverse cardiac and cerebrovascular events(MACCE) by logistic regression.Methods Data on 239 CAD patients combined with DM aged ≤45 who underwent CABG in our hospital were collected retrospectively from October 2007 to October 2016.There were 216 males and 23 females,the mean age was (42.15 ±2.59) years old.The mean LVEF was 0.59 ±0.09.43 patients (18.0％) had left main stenosis,and the average diseased vessel number was 3.20 ± 0.76.Results One patients (0.4％)in-hospital died of heart failure.Patients received (3.12 ±0.81) bypass grafts overall,12 patients (5.0％) were total artery revascularization.3 patients (1.3％) needed reoperation for bleeding and the perioperative atrial fibrillation rate was occured in 23 patients (9.6％).The follow-up rate was 95％ (226 cases),the median follow-up time was 5 years (1-9 years).8 patients (3.3％) died of all cause-mortality,and 183 patients (81.0％) were freedom from MACCE.The higher level of BMI、cholesterol and creatinine,LVEF ≤0.35,postoperative blood loss ≥ 1 000 ml and ventricular arrhythmia were the independent risk factors of MACCE.Conclusion CABG procedure in CAD patients under 45 years old accompanied DM is safety and reliable both in early and long-term outcomes.
