Clinical Study for Evaluating the Safety and Efficacy of Total Endovascular Aortic Arch Repair

Inclusion Criteria: * Patients have aortic arch lesions caused by atherosclerosis and hypertension, and are also suitable for both chimney/ fenestration / branch stent-grafts technique and total arch replacement surgery simultaneously. * Lesions involve the aortic arch, at least one branch of the aortic arch to be revascularized. * The type of lesion is dissection, aneurysm, pseudoaneurysm, or ulcer. * Life expectancy is more than 1 year. * Patients are able to understand the purpose of this trial, voluntarily attend and sign the informed consent form, and are willing to accept the specified follow-up at specific time point. Exclusion Criteria: * Patients had a stroke or ST-segment elevation myocardial infarction within 30 days prior to surgery. * Patients underwent major surgery (grade 3 or above) or interventional therapy within 30 days prior to surgery. * Patients will undergo any major elective surgery (grade 3 or above) or interventional therapy within 30 days after surgery. * Patients had a previous thoracic aortic surgery in the past. * Patients had previous thoracic aortic endovascular treatment, and the last implants had an effect on this procedure or had intersections with implants would be used in this procedure. * Patients need intervention in other vascular lesions (such as coronary arteries, lower extremity arteries, carotid arteries) in the same procedure, or have heart disease and postoperative medication regimens are affected. * Patients have hepatic and r…
