Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients aged 18 to 80 years old; 2. The patient was diagnosed with subacute or chronic aortic arch dissection; 3. Patients showing a suitable vascular condition, including: Ascending aorta length > 50 mm (from the aortic sinusoid junction to the proximal cardiac margin of the innominate artery); Ascending aorta diameter >= 24 mm and = 30 mm; Innominate artery diameter = 7 mm, length >= 20 mm; Left common carotid artery or left subclavian artery diameter = 7 mm, length >= 20 mm; Suitable arterial access for endovascular interventional treatment ; 4. Patients able to understand the purpose of the trial, participate in the trial voluntarily with informed consent form signed by the subject him/herself or his or her legal representative, and willing to complete follow-up visits as required under the protocol; 5. Patients evaluated by at least two vascular surgeons or cardiac surgeons as high surgical risk patients or deemed to have significant surgical contraindications. (The recommended reference criteria are: EuroSCORE score >= 6, or ASA grade 3-4, or CFS score > 4, or there are other high-risk surgical factors that affect the prognosis of the subject, such as patients with a history of open surgery, other high-risk factors judged by a physician team, or patients who refuse open surgery.
