入选标准

  • Presence of acute complicated type B aortic dissection:
  • Dissection is acute Time from symptom onset to dissection diagnosis ≤14 days
  • Dissection is complicated
  • Subject must present with at least one of the following:
  • Rupture in the setting of an aortic dissection defined as hemorrhage outside of the aortic boundaries -which is noted by CT scan (hemorrhage must be differentiated from reactive effusions by the investigator, or if equivocal, having elevated Hounsefield units as determined by the radiologist).
  • Clinical evidence of malperfusion, in the setting of an aortic dissection, defined as:
  • Clinical or radiographic evidence of visceral hypoperfusion.
  • Clinical or radiographic evidence of renal hypoperfusion.
  • Clinical or radiographic evidence of lower extremity hypoperfusion.
  • Clinical or radiographic evidence of spinal cord hypoperfusion.
  • Dissection is type B Entire dissection is distal to the left subclavian artery
  • Primary Treatment Indication is Class 1 Aortic Dissection 46 Classical aortic dissection with intimal flap between true and false lumen with double barrel flow in thoracic aorta
  • Subjects with multiple entry tears are allowed to be enrolled in the study
  • Age 18 to 80 years
  • Primary treatment is endovascular treatment with the CTAG device. Adjunctive treatments may include left subclavian artery revascularization, percutaneous fenestration, aortic stenting, peripheral vessel stenting, surgical fenestration, and/or peripheral artery bypass
  • Proximal landing zone characteristics include:
  • Proximal extent of intended proximal landing zone cannot be dissected
  • Length ≥ 2.0 cm proximal to the primary entry tear
  • Trans-aortic diameter at proximal extent of intended landing zone between 16-42 mm (diameter assessed by flow lumen and thrombus, if present; calcium excluded)
  • Cannot be aneurysmal, heavily calcified, or have excessive intraluminal thrombus
  • Must be native aorta
  • May include left subclavian artery, if necessary
  • Subject is capable of complying with protocol requirements, including follow-up
  • Informed Consent Form is signed by subject or legal representative

排除标准

  • Primary treatment indication is Class 2-5 aortic dissection (intramural hematoma, limited dissection, penetrating atherosclerotic ulcer, iatrogenic dissection, traumatic dissection) 46
  • Concomitant aneurysm/disease of the ascending aorta, aortic arch, or abdominal aorta requiring repair (dissection extension into the abdominal aorta is acceptable)
  • Prior repair of DTA
  • Infected aorta
  • Subject has a systemic infection and may be at increased risk of endovascular graft infection
  • Persistent refractory shock (systolic blood pressure <90 mm Hg)
  • Bowel necrosis (Bowel necrosis will be characterized by direct observation with surgical exploration, or elevated serum lactate level and CT findings of portal venous gas, free intra-abdominal gas, pneumatosis intramural gas, and poor mucosal enhancement of thickened bowel wall)
  • Renal failure , defined as baseline creatinine ≥ 2.5 mg/dl
  • ASA risk classification = V (Moribund patient not expected to live 24 hours with or without operation)
  • Pregnant female
  • Major surgery within 30 days of treatment (other than left subclavian artery bypass or transposition)
  • Degenerative connective tissue disease, e.g., Marfan or Ehler-Danlos Syndrome
  • Treatment in another drug or medical device study within 1 year of study enrollment
  • History of stimulant abuse, e.g., cocaine or amphetamine, within 1 year of treatment
  • Tortuous or stenotic iliac and/or femoral arteries and the inability to use a conduit for vascular access
  • Planned coverage of left carotid or celiac arteries with the CTAG device
  • The planned endovascular procedure involves alterations to the CTAG device
  • Subject has known sensitivities or allergies to the device materials
