Aortic Aneurysm Repair
Aortic aneurysm repair strengthens a dangerously enlarged section of the aorta to prevent it bursting, using either keyhole (EVAR) or open surgery.
Quick answer
Aortic Aneurysm Repair: what it is, why it's done and what happens
An aortic aneurysm is a bulge in the wall of the aorta, the body’s main artery. Repair reinforces or replaces the weakened section, either by placing a stent graft from inside (EVAR) or by open surgery to replace it with a graft.
- Why it is done: It is used for aneurysms that have grown large enough to risk bursting, which can be life-threatening, or that are enlarging quickly or causing symptoms.
- What happens: In keyhole repair (EVAR), a stent graft is guided into place through the leg arteries under X-ray guidance.

An aortic aneurysm is a bulge in the wall of the aorta, the body’s main artery. Repair reinforces or replaces the weakened section, either by placing a stent graft from inside (EVAR) or by open surgery to replace it with a graft.
Why it is done
It is used for aneurysms that have grown large enough to risk bursting, which can be life-threatening, or that are enlarging quickly or causing symptoms.
What happens
In keyhole repair (EVAR), a stent graft is guided into place through the leg arteries under X-ray guidance. In open repair, the aorta is opened and replaced with a graft. Both are done under anaesthetic.
Recovery
EVAR usually allows a shorter hospital stay and quicker recovery, with ongoing scans to check the graft. Open repair is bigger surgery with recovery over several weeks to months.
Good to know
Risks and things to consider
Risks include bleeding, kidney problems, and graft complications; EVAR needs long-term monitoring for leaks. Open repair is more invasive but avoids the need for as much follow-up imaging.

Answers
Aortic Aneurysm Repair: frequently asked questions
What is the difference between EVAR and open repair?
EVAR places a stent graft from inside the artery through small cuts in the groin, with quicker recovery but lifelong scans. Open repair replaces the section directly and is bigger surgery but needs less imaging afterwards.
Why is an aneurysm repaired before it bursts?
A burst aortic aneurysm is a life-threatening emergency with a high risk of death. Planned repair when the aneurysm reaches a certain size is much safer than emergency treatment.
