Abstract：Objective:To evaluate the efficacy and safety of endovascular repair in Stanford type B aortic dissection patients across different age groups.Method:A total of 102 Stanford type B aortic dissection patients treated in Taizhou Second People's Hospital from January 2019 to December 2023 were selected as the study objects,and were divided into the young and middle-aged group(age≤60 years old)and the elderly group(age＞60 years old)according to age,with 51 cases in each group.Both groups received endovascular prosthesis.The general data,perioperative indexes,postoperative aortic remodeling and complication rate were compared between the two groups.Result:The operation time and intensive care time of the young and middle-aged groups were shorter,and the use of contrast agent was less,and the difference was statistically significant(P＜0.05).Before operation,the true cavity diameter of aortic isthmus and pulmonary artery bifurcation in the elderly group was smaller than that in the young and middle-aged group,and the false cavity diameter of aortic isthmus and pulmonary artery bifurcation in the elderly group was larger than that in the young and middle-aged group,and the difference was statistically significant(P＜0.05).6 months after operation,the true cavity diameter increased and the false cavity diameter decreased in both groups,and the change amplitude was greater in the young and middle-aged group,and the difference was statistically significant(P＜0.05).The incidence of total complications was lower in the young and middle-aged groups,and the difference was statistically significant(P＜0.05).Conclusion:Endovascular repair in middle-aged and young Stanford type B aortic dissection patients shows superior perioperative management outcomes,better postoperative aortic remodeling,and a lower complication rate.Age is a significant factor affecting treatment efficacy and safety.
