Effectiveness and Safety of a Type A Dissection Total Endovascular Reconstruction System in Promoting Favorable Distal Aortic Remodeling

This is a prospective, multicenter, randomized controlled clinical study. A total of 198 eligible subjects will be enrolled and randomly assigned in a 1:1 ratio to either the Study Group or the Control Group. Subjects in the Study Group will receive surgical treatment using the study device (Type A Dissection Total Endovascular Reconstruction System) in addition to standard medical therapy following the Total Arch Replacement with Frozen Elephant Trunk. Subjects in the Control Group will continue standard medical therapy without surgical treatment using the study device following Total Arch Replacement with Frozen Elephant Trunk. Clinical follow-ups will be conducted at 30 days (±7 days), 6 months (±30 days), and 12 months (±30 days) post-enrollment to evaluate the effectiveness and safety of the study device. After all subjects complete the 12-month (±30 days) follow-up, a statistical analysis will be performed and the results will be submitted for the study device registration application. Long-term follow-up will continue for 2-5 years post-enrollment.
