入选标准

  • Aged 18 to 80 years
  • Diagnosed with aortic arch pathology requiring intervention, including:
  • True aortic arch aneurysm
  • Pseudoaneurysm of the aortic arch
  • Penetrating aortic ulcer involving the arch
  • Deemed suitable for endovascular repair by the investigating physician
  • Capable of understanding study objectives, providing written informed consent, and complying with follow-up requirements
  • Anatomic suitability confirmed by CTA:
  • Ascending aortic length ≥50 mm
  • Ascending aortic diameter ≥26 mm and ≤46 mm
  • Proximal landing zone length ≥20 mm
  • Brachiocephalic trunk diameter ≥9 mm and ≤19 mm with length ≥20 mm
  • Left common carotid artery (LCCA) and left subclavian artery (LSA) diameters ≥5 mm and ≤13 mm
  • LCCA length ≥20 mm
  • Distance from LSA ostium to left vertebral artery origin ≥20 mm
  • High surgical risk per investigator assessment OR contraindicated for open surgery

排除标准

  • Pregnant or lactating women
  • Connective tissue disorders affecting the aorta (e.g., Marfan syndrome, Ehlers-Danlos syndrome)
  • Infected aortic pathologies or aortitis (e.g., mycotic aneurysm, Takayasu arteritis)
  • Prior endovascular repair of ascending aorta/aortic arch
  • Documented allergy to nitinol, contrast media, or device materials
  • Severe renal impairment:(Serum creatinine >2×ULN,Excluding dialysis-dependent patients)
  • Hematologic abnormalities:(WBC <3×10⁹/L、Hb <70 g/L、PLT <50×10⁹/L)
  • Heart transplant recipients
  • Myocardial infarction or stroke within 3 months
  • NYHA Class IV heart failure
  • Active systemic infection (e.g., bacteremia, sepsis)
  • Life expectancy <12 months
  • Mechanical aortic valve prosthesis impeding device delivery
  • Current participation in other interventional trials with primary endpoint pending
  • Anticipated poor compliance with follow-up
  • Other contraindications for endovascular repair per investigator assessment:Severe vascular stenosis/calcification/tortuosity/Thrombus at landing zones/Inability to cooperate with procedure

结局指标

主要结局

12-month treatment success rate

时间窗: 12-month

Technical success at the index procedure, without device- or aortic pathology-related mortality or unplanned secondary interventions, and with no evidence of persistent enlargement of the treated aortic segment due to Type I/III endoleaks on 12-month CTA follow-up.

30-day rate of Major Adverse Events (MAE)

时间窗: 30-day

Including all-cause mortality, disabling stroke, persistent paraplegia, renal failure, myocardial infarction, and respiratory failure
