Objective To summarize experience of concomitant endovascular aneurysm aortic repair(EVAR) and coronary artery bypass grafting(CABG) for patients of severe coronary artery disease(CAD) complicated with infra-renal abdominal aortic aneurysm(AAA) or infra-renal abdominal penetrating aortic ulcer(PAU).Methods Between January 2013 and December 2016,13 patients with severe CAD and infra-renal AAA/PAU who underwent CABG and EVAR were enrolled in this study.12 patients (92.3 ％) were male and 1 patient was female (7.7 ％),the mean age of(63.7 ± 7.3) years.11 patients with CAD related symptoms,2 patients with AAA/PAU related symptoms,abdominal aortic lesions include:AAA in 3cases,PAU in 10 cases,2 patients combined with PAU of the thoracic aorta.CABG and EVAR manipulations were performed according to the routine protocol,patients who were combined with thoracic aorta PAU were treated with thoracic endovascular aortic repair (TEVAR) simultaneously.Results 7 patients received EVAR followed by CABG;6 patients received CABG followed by EVAR,TEVAR were performed in 2 patients.For all the patients,there were 11 cases of CABG were performed under the cardiopulmonary bypass(CPB) (ON-PUMP) and 2 others cases were performed without CPB(OFF-PUMP).On the average(2.5 ± 0.7)grafts were performed.The time of aortic clamp and CPB averaged were(50.7 ± 16.5)min and (58.0 ± 11.2)min respectively for the ON-PUMP CABG patients.Totally 30 thoracic aorta and abdominal aorta stent grafts were implanted in 13 patients.The duration of postoperative mechanical ventilation time was (17.8 ± 7.0) hours,Median intensive care stay was (2.7 ± 1.9) days,while hospital stay was(8.1 ± 2.4)days.All the patients was discharged.1 patient suffered wound unhealing 2 days after discharging,followed by sternal infection,he was re-admitted and received pectoralis major myocutaneous flap transfer operation,29 days after this operation,he suffered sudden cardiac arrest and eventually dead.The other 12 surviving patients was followed up for 1 ～ 36 months,The results showed that the patency of the grafts in all patients was good,no EVAR related secondary interventions were required.Conclusion For the patients with surgical indications,the procedure of one stage CABG and EVAR completed by one surgical team was safe and feasible.Comparing with the traditional one stage or staged surgical repair,this strategy showed less surgical trauma,shorter operation time,lower perioperative risks,more efficacy and more conducive to the overall management of patients.
