描述

Inclusion Criteria:

  • An aneurysm with a maximum diameter of >5.5cm in males and >5.0cm in females in diameter just proximal to the aneurysm using orthogonal (i.e., perpendicular to the centerline) measurements
  • Aneurysm with a history of growth > 0.5 cm in 6 months
  • Saccular aneurysm deemed at significant risk for rupture
  • Symptomatic aneurysm
  • Extent of aorta to be treated: type II, III and IV thoracoabdominal.
  • Subject is at high-risk of morbidity and mortality with open surgical repair as defined by FEV1 of <1 liter or uncorrectable coronary disease, frailty, hostile abdomen.
  • Iliac or femoral access vessel morphology that is compatible with vascular access techniques, devices or accessories, with or without use of a surgical conduit.
  • Non-aneurysmal aortic segment proximal to the aneurysm (neck) with a:
  • Minimum neck length of 15mm
  • Diameter in the range of 17-32
  • Minimum branch vessel diameter greater than 5 mm
  • Iliac artery distal fixation site
  • An inside diameter of 8mm - 13mm and a length of ≥ 10mm or
  • an inside diameter of > 13mm - 20mm and a length of ≥ 15mm
  • Age: ≥50 years old

Exclusion Criteria:

  • Can be treated in accordance with the instructions for use with a legally marketed endovascular prosthesis
  • Is eligible for enrollment in a manufacturer-sponsored IDE at the investigational site
  • Unwilling to comply with the follow-up schedule
  • Inability or refusal to give informed consent by subject or legal representative
  • Subject is pregnant or breastfeeding
  • Ruptured aneurysms
  • Prior aortic repair
  • Patient is eligible for treatment with an FDA-approved marketed device and patient can enroll in a manufacturer-sponsored clinical study at our institution or is willing and eligible to participate in a study with a manufacturer-made device at another institution.
  • Known sensitivities or allergies to the materials of construction of the devices, including nitinol, polyester, PTFE, stainless steel, platinum/iridium, tantalum markers.
  • Known hypersensitivity or contraindication to anticoagulation or contrast media that cannot be adequately medically managed
  • Uncorrectable coagulopathy
  • Body habitus that would inhibit x-ray visualization of the aorta or exceed the safe capacity of the equipment
  • Subject has had a major surgical or interventional procedure unrelated to the treatment of the aneurysm planned < 30 days of endovascular repair
  • Unstable angina (defined as angina with a progressive increase in symptoms, new onset at rest or nocturnal angina)
  • Systemic or local infection that may increase the risk of endovascular graft infection
  • Baseline creatinine greater than 2.0 mg/dL
  • Thrombus or excessive calcification within the neck of the aneurysm
  • Branch stenosis >50% not amenable to endovascular preparation

大体时间
Proportion of study subjects with treatment success at 1 year
大体时间:1 year

Treatment success is defined as freedom from the following:

  • Aneurysm enlargement: >5mm as compared to any previous CT measure using orthogonal (i.e., perpendicular to the centerline) measurements.
  • Aneurysm rupture
  • Aneurysm-related mortality
  • Conversion to open repair
  • Secondary intervention for migration, Type I and III endoleaks, device integrity failure (e.g., fracture), and patency-related events (i.e., device component stenosis or occlusion and embolic events)
  • Graft infection
  • Disabling Stroke
  • Permanent dialysis

大体时间:1 year

Technical success is defined as:

  • Successful access to the arterial system using remote arterial exposure, percutaneous technique, or open surgical conduits
  • Successful delivery and Deployment at the intended implantation site
  • Successful side branch catheterization and placement of bridging stents with restoration and maintenance of flow in all intended target vessels.
  • Successful withdrawal of the delivery system
  • Patency of all endovascular graft and stent components
  • Absence of device deformations requiring unplanned placement of an additional device
  • Absence of Type I and III endoleaks at completion angiography that extends beyond 30 days by confirmatory imaging (CTA, MRA or duplex ultrasound)
