Outcome Measures

Primary Outcomes (1)

  • Rate of all-cause mortality and major stroke within 12 months after surgery

    All-cause mortality includes cardiac mortality, non-cardiac mortality, and mortality from unknown causes. Severe stroke is defined as a modified Rankin score (mRS) ≥ 2 at 90 days following stroke onset.

    12 months after surgery

Secondary Outcomes (10)

  • Rate of immediate technical success following surgery

    immediately after the surgery

  • Rate of aortic aneurysm progression under control

    12 months after operation

  • Incidence of Type I or Type III endoleak

    immediately after the surgery, 1 month, 6 months, 12 months after the surgery

  • Incidence of aortic arch stent graft displacement

    1 month, 6 months, 12 months after operation

  • Postoperative branch vessel patency rate

    1 month, 6 months, 12 months after operation

  • +5 more secondary outcomes

Study Arms (1)

  • Diagnosed with aortic arch lesions requiring intervention, including true aortic arch aneurysms, pseudo-aortic arch aneurysms, and ulcers involving the aortic arch;
  • 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;
  • Innominate artery diameter ≤ 24 mm and ≥ 7 mm, length ≥ 20 mm;
  • Left common carotid artery or left subclavian artery diameter ≤ 24 mm and ≥ 7 mm, length ≥ 20 mm;
  • Suitable arterial access for endovascular interventional treatment;
  • 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.
  • Evaluated by at least two vascular surgeons or cardiac surgeons as high surgical risk patients or deemed to have significant surgical contraindications.

You may not qualify if:

  • Experienced systemic infection during past three months;
  • Neck surgery was performed within 3 months;
  • Previous endovascular interventional treatment involving the aortic arch was performed;

  • Severe stenosis, calcification, thrombosis, or tortuosity of the carotid or subclavian artery;
  • Heart transplant;
  • Suffered MI or stroke during past three months;
  • Class IV heart function (NYHA classification);
  • Active peptic ulcers or upper gastrointestinal bleeding occurring within the previous three months;
  • Hematological abnormality, defined as follows: Leukopenia (WBC \< 3 × 109/L), acute anemia (Hb \< 90 g/L); thrombocytopenia (PLT count \< 50 × 109/L), history of bleeding or coagulopathy;
  • Renal insufficiency, creatinine \> 265 umol/L (or 3.0mg/dL) and/or end-stage renal disease requiring renal dialysis, as determined by an investigator after a thorough analysis;
  • Pregnant or breastfeeding;
  • Allergies to contrast agents;
  • Life expectancy of less than 12 months;
  • Participating in another drug or device research;
  • +1 more criteria
