Outcome Measures
Primary Outcome Measures
- Rate of no major adverse events related to device or surgery [30 days after surgery]
Major adverse events related to device or surgery include: stroke, respiratory failure, pericardial tamponade, dissection or aneurysm rupture, paraplegia, stent occlusion, stent bend, stent displacement, thrombosis or rupture of the approach vessel, switch to open surgery, death, etc.
Secondary Outcome Measures
- Technical success rate [immediately after the surgery]
Successful delivery of the stent graft conveyors to their predetermined positions, accurate positioning and successful deployment of the stent, safe removal of the delivery device outside the body.
- Immediate surgery success rate [immediately after the surgery]
Successful delivery of the stent graft, no major adverse events related to devices or surgery.
- The clinical success rate [12 months after the surgery]
Clinical success rate:12 months after the operation, there was no displacement of the stent, I and III endoleak requiring treatment, aneurysm enlargement or rupture, and branch stent occlusion.
- The incidence rate of secondary operations within 12 months after surgery [12 months after surgery]
The incidence rate of secondary operations within 12 months after surgery.
- Adverse event rate within 12 months after surgery [12 months after surgery]
Adverse event rate within 12 months after surgery.
