Objective:To summarize acute type A aortic dissection(ATAAD) is relatively uncommon in dialysis patients, and repair outcomes are not fully understood.Methods:Between January 2014 and March 2020, 20 patients with ATAAD required dialysis for preoperative end-stage renal disease(ESRD) were treated by our group. There were 11 male and 9 female patients at mean age of(47.8±11.3) years. The mean duration of dialysis therapy in the total 20 patients before the onset of ATAAD was(4.5±3.9 )years, with 90%(18 cases) of these patients undergoing hemodialysis(rather than peritoneal dialysis). 17 patients were treated emergency surgically, surgical operation were performed under deep hypothermic circulatory arrest and perfused the cerebral selective cerebral perfusion, 5 cases with ascending aorta + arch fenestrated stent, 5 cases with ascending aorta+ hemi-arch replacement(2 cases with stent elephant trunk), 4 cases with ascending aorta+ arch replacement+ stent elephant trunk(1 case with coronary artery bypass grafting for left anterior descending coronary artery), 2 cases with aortic valvuloplasty + ascending aorta+ hemi-arch replacement, 1 case with Bentall+ arch fenestrated stent.Results:2 patients were died from aortic ruptured before operation, 1 patient treated medically was alive three months after admission. Cross-clamp, cardiopulmonary bypass, and circulatory arrest times of all the surgical patients were(233.8±84.4) min, (155.5±63.6)min and(28.2±10.8)min, respectively. The following complications occurred postoperative: 3 cases died in the hospital, 1 case of tracheotomy, 2 cases of cerebral infarction, 1 case of cerebral hemorrhage, 1 case of transient paraplegia, and 1 case of surgical site infection. After a mean follow-up of(11.6±14.5) months(rang, 3-61 months). the overall survival rate at 1 year and 5 years was 53% and 27% respectively.Conclusion:Dialysis patients with ATAAD should be operated on urgently and medical treatment carries high risks of aortic rupture, although in-hospital mortality is acceptable, long-term mortality is poor.
