The objective of this study is to evaluate the feasibility of multibranched stent graft system for Endovascular Treatment of Thoracoabdominal Aortic Aneurysm(TAAA)
Age ≥18 and ≤80 years;
Maximum diameter of TAAA >50 mm,
Rapid growth of sac >5 mm in diameter in the most recent 6 months, or rapid growth >10 mm in diameter within 1 year
Symptoms related to thoracoabdominal aortic aneurysm, such as clear abdominal pain and back pain.
Ruptured aortic aneurysm in unstable haemodynamic condition;
Aneurysmal aortic dissection;
Infected or mycotic aortic aneurysm;
Patients whose systemic or local infection may increase the risk of intravascular graft infection;
