Abstract：Objective This study compared the early and mid-term efficacy of type Ⅱ hybridization technology and improved Sun's surgery in patients with acute type A aortic dissection through retrospective analysis,aiming to evaluate the effectiveness of type Ⅱ hybridization technology in the treatment of type A aortic dissection.Methods Data of patients who underwent aortic arch replacement surgery from February 2020 to December 2023 at the Fourth Hospital of Hebei Medical University were retrospectively analyzed.A total of 90 patients were selected in this study,of which 45 had modified aortic arch replacement and elephant rhinoplasty stent placement(modified group),while the other 45 patients underwent a phase Ⅱ hybrid repair surgery(hybrid group).All patients were performed surgey successfully.Results There were 13 cases in the modified group aged over 60 years and 11 cases in the hybrid group(P=0.634).There was no significant difference between preoperative hypertension,diabetes and coronary heart disease(P>0.05).The two groups had preoperative differences in preoperative hypertension,diabetes and coronary heart disease(P>0.05).There was no significant difference in renal insufficiency and pericardial tamponade(P>0.05).The transit time of the hybrid and improved groups was(191.31±30.61)min and(235.03±46.84)min,the aortic occlusion time was(130.67±26.50)min and(175.71±40.35)min,and the low flow time was(2.53±0.66)min and(5.64±3.47)min,the differences between the two groups were statistically significant(P<0.001).There was no significant difference between the patients in CICU residence time,postoperative hospitalization time,and secondary thoracic hemostasis cases(P>0.05).Multi-organ dysfunction syndrome was the only postoperative complications which was better in the hybrid group than that in the modified group(P<0.05).Conclusion Type Ⅱ hybrid treatment for acute Stanford A aortic dissection can shorten the extracorporeal circulation time,aortic occlusion time and low flow time.The postoperative complications are better than those of modified Sun's surgery,but the long-term efficacy still requires further in-depth study of large samples.
