Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Major Adverse Events (MAE) Within 30 Days Postoperative

    Major Adverse events (MAE) are defined as all-cause death, liver failure, intestinal necrosis, splenic infarction, renal infarction, renal failure, cerebral infarction, paraplegia, myocardial infarction, and respiratory failure.

    within 30-days postoperative

Study Arms (1)

G-Branch Thoracoabdominal Aortic Stent System

EXPERIMENTAL

Patients with Crawford type I-V thoracoabdominal aortic aneurysms and Pararenal abdominal aortic aneurysm, and passed the screening and signed the Informed Consent Form

Device: Thoracoabdominal aortic stent system

Interventions

Patients who meet all inclusion criteria and don't meet any exclusion criteria were implanted with thoracoabdominal aortic stent system.

  • Rapid growth of sac \>5 mm in diameter in the most recent 6 months;
  • Definite symptoms of abdominal pain and low back pain associated with thoracicabdominal aortic aneurysms.
  • Patients with four indispensable reno-visceral arteries including superior mesenteric artery, celiac trunk and bilaterial renal arteries.
  • Proximal landing zone 20-36 mm in diameter;
  • Proximal landing zone ≥25 mm in length;

  • Severe stenosis, calcification, or mural thrombus at stent-graft landing zone;
  • Diagnosis of acute coronary syndrome within 6 months;
  • Patients with any transient ischemic attack (TIA) or ischemic stroke within 3 months;
  • An allergic history for contrast agents, anticoagulants, antiplatelet drugs, stent graft or materials of delivery system;
  • Patients with connective tissue diseases;
  • Patients with takayasu arteritis;
  • Patients with serious vital organ dysfunction or other serious disease;
