About this study
Official title: A Single-arm, Open-label, Multicenter Clinical Study Evaluating the Safety and Efficacy of Endovascular Treatment for Retrograde Dissections Involving the Ascending Aorta That Are Not Suitable for Open Surgery. (RADIAL)
This study is a single-arm, open-label, multi-center clinical trial evaluating the safety and efficacy of endovascular treatment for retrograde dissection involving the ascending aorta that is not suitable for open surgery. The aim is to assess the short-term (30 days) and medium- to long-term (6 months and 12 months) safety and efficacy of endovascular treatment in patients with retrograde dissection involving the ascending aorta who are not suitable for open surgery. The study plans to include patients with dissection confirmed by imaging, with the tear located in the aortic arch or descending aorta and extending retrogradely to the ascending aorta, and the most distal segment of the dissection is at least 2 cm away from the coronary artery ostia. These patients have been evaluated by cardiac surgery and found to be unsuitable for open surgery, with significant risks or risks outweighing benefits associated with open surgery. This is a single-arm, open-label, multi-center study, and no blinding or randomization will be used, nor will stratification factors be set. After successful screening, the subjects will undergo endovascular treatment for aortic dissection (stent implantation) during the operation. The subjects will be followed up for one year after the operation, and the safety and efficacy of endovascular treatment for retrograde dissection involving the ascending aorta will be evaluated based on the subjects' survival status, the occurrence of surgery and disease-related complications, and the recovery of the disease.
