Triple-branched stent graft system for aortic arch lesions

Official title: Safety and Efficacy of the Triple Branched Covered Stent Graft System for the Treatment of Aortic Arch Lesions: a Prospective, Multicenter, Single-Arm Trial.

Run by Changhai Hospital · NCT07067840 · Data updated 2026-11-12

This trial tests whether the triple branched covered stent graft can safely treat aortic arch lesions and achieve a high 12‑month treatment success with a low 30‑day major adverse events in adults.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–80 with specific aortic arch lesions (true/false aneurysms or ulcers) suitable for endovascular repair and meeting detailed anatomical criteria.

Probably not a fit

Patients not meeting anatomical criteria or who have higher risk factors or complications may not benefit and could be at risk from the intervention.

What this trial studies

This is a single‑arm interventional study evaluating the Triple Branched Covered Stent Graft System for aortic arch lesions (aneurysms and ulcers). Participants undergo endovascular implantation and are followed at pre‑discharge, 30 days, 6 months, and 12 months to assess safety and efficacy against predefined targets. The study uses predefined primary endpoints to determine treatment success at 12 months and MAE rates at 30 days. Eligibility focuses on adults with specific anatomical criteria making them high risk for open surgery. Investigators screen candidates and ensure proper follow‑up as part of the protocol.

Why it matters

Potential benefit: If successful, patients may experience improved aneurysm/ulcer treatment with a less invasive option and potentially reduced risk from open surgery.

How similar studies have gone: Other endovascular graft approaches have shown safety in similar arches, but this exact triple branched system is being evaluated for its specific feasibility and outcomes.

* Inclusion Criteria:

  1. Patients aged 18-80 years.
  2. Diagnosed with aortic arch lesions that require treatment, including true aortic arch aneurysms, false aortic arch aneurysms, and aortic arch ulcers.
  3. The investigator determines that the subject is suitable for endovascular therapy.
  4. The subject understands the purpose of the trial, voluntarily agrees to participate, and is willing to undergo follow-up.
  5. Anatomical conditions:

     * Ascending aorta length ≥50 mm.
     * Ascending aorta diameter ≥26 mm and ≤46 mm.
     * Proximal landing zone length ≥20 mm.
     * Brachiocephalic artery diameter ≤19 mm and ≥9 mm, with a length ≥20 mm.

  3. Infectious aortic diseases or Takayasu arteritis.
  4. Patients who have undergone endovascular treatment of the ascending aorta or aortic arch.
  5. Patients with a known allergy to nickel-titanium alloy, contrast agents, or other relevant materials.
  6. Severe renal failure (creatinine levels more than twice the upper limit of normal; dialysis patients are excluded).
  7. Hematological abnormalities:

     * Leukopenia (WBC \< 3×10⁹/L).

  9. History of myocardial infarction or stroke within the past 3 months.
  10. Heart function class IV (NYHA classification).
  11. Active infections, such as bacteremia or sepsis.
  12. Patients with an expected survival of less than 12 months.
  13. Patients with aortic valve replacement with a mechanical valve that would interfere with the safe introduction of the trial device.
  14. Subjects participating in other drug or medical device clinical trials and have not yet completed the primary endpoints of those trials.
  15. Poor compliance, with an expectation of inability to attend follow-up visits.
  16. Other conditions deemed by the investigator as unsuitable for endovascular therapy, such as severe vascular stenosis, calcification, tortuosity, thrombosis, or inability to cooperate.
