What is this trial about?

A prospective ,Multiple Center Study About the Safety and Efficacy of WeFlow-Tribranch Embedded Aortic Triple-branch Arch Stent Graft System manufactured by EndoNom Medtech (Hangzhou) Co., Ltd. for true/pseudo aortic arch aneurysms and ulcers involving aortic arch . (GENIUS Study)

What are the participation requirements?

Yes

Inclusion Criteria

1. Patients aged 18 to 80 years old;

2. Diagnosed with aortic arch lesions requiring intervention, including true aortic arch aneurysms, pseudo-aortic arch aneurysms, and ulcers involving the aortic arch;

3. Showing a suitable vascular condition, including:

- Ascending aorta length greater than 50 mm (from the aortic sinusoid junction to the proximal cardiac margin of the innominate artery).
- Ascending aorta diameter ≥ 24 mm and ≤ 48 mm;
- Proximal anchoring zone length ≥ 30 mm;
- Branch arteries to be reconstructed were ≤ 24 mm and ≥ 6 mm in diameter and ≥ 20 mm in length;
- Suitable arterial access for endovascular interventional treatment;

4. Able to understand the purpose of the trial, participate in the trial voluntarily with informed consent form signed by the patient him/herself or his or her legal representative, and willing to complete follow-up visits as required under the protocol.

5. Subjects were assessed as high risk for surgery by at least two investigators or judged to have significant surgical contraindications.
