What is the survival rate of an aortic aneurysm?
Ruptured abdominal aortic aneurysms (RAAAs) continue to be a significant cause of death in the United States. Mortality rates after repair of an RAAA have not significantly changed in the literature in the past 20 years, still ranging between 30% and 70% in the most recent reports.
What is AAA Endoprosthesis?
The Gore® Excluder® Conformable AAA Endoprosthesis is a device used to repair an aneurysm (a weakened and “ballooning” part) of the infrarenal abdominal aorta, the largest artery in the abdomen below the kidneys.
What does EVAR mean in medical terms?
Endovascular abdominal aortic aneurysm repair (EVAR) is a procedure to treat AAAs with an endograft (a device) without the need for open surgery. In this procedure, a single or bilateral incision is made in the groin, and a stent graft is passed into the aneurysm from a catheter inserted via the femoral artery.
What does Endoleak mean?
An endoleak is a complication that affects about 15-25% of patients who have EVAR. It means that some amount of blood flow still remains in the aneurysm cavity.
How long does it take to recover from EVAR surgery?
Full recovery takes between 3 and 6 months after open surgery and 2 to 4 weeks after endovascular repair.
Is endoleak an emergency?
Although it is a rare complication in third-generation stent grafts, type III endoleaks need to be seen as an emergency, because they lead to repressurization of the aneurysm sac and a ninefold higher risk of secondary rupture.
Is an endoleak serious?
The most common complications are endoleaks [4, 6]. Type I endoleak is one of the most life-threatening. There are two types of this endoleak: IA, which means a leak at the proximal part of the stent graft; and type IB, when the leakage is situated in the distal part of the stent graft.
Is EVAR high risk?
Of the patients undergoing EVAR, 48% of patients were characterized as high risk and 52% as low risk.
How do you fix an endoleak?
Treating Endoleaks
- Puncturing an aneurysm, then adding coils or glues to close it.
- Delivering blood-clotting medicine through your blood vessels to stop the leak.
- Using special glue-like material to stop the leak.
- Extending the stent-graft.
- Placing special cuffs to seal the ends of the stent-graft.
