What is an endovascular aneurysm?

An aneurysm occurs when the wall of a blood vessel weakens causing it to bulge (swell). This can be dangerous if it gets bigger and ruptures (bursts).

If you’ve been diagnosed with an aneurysm, your consultant may suggest you have EVAR treatment if they find a vascular abnormality, known as an aneurysm, in your abdomen or chest.

Aneurysms don't usually have any symptoms until they burst, by which point you'd require emergency treatment. So preventative treatment is often the best course of action. An endovascular aneurysm repair (EVAR) is a type of keyhole surgery, that your consultant may recommend.

Need to know

It involves a graft (stent) being inserted into your blood vessel and placed inside the aneurysm. This is done through small cuts made in your skin via your groin, using x-ray images. Your blood will start to flow through the graft rather than the aneurysm, this will take pressure off the aneurysm and significantly reduce the chance of it rupturing.

It is less invasive than other surgical treatment options which means that you should have a quicker recovery time.

As with all procedures, there may be some risks and side effects involved. Your surgeon will explain these to you and answer any questions you have. The EVAR is usually done while you’re asleep under general anaesthetic. We will let you know in advance how long to avoid eating and drinking before your surgery.

When the procedure is completed, you should be able to eat and drink normally once you are fully awake.

Prior to your procedure, your consultant will explain the EVAR to you and answer any questions you might have.

You'll be cared for in hospital for one or two nights so we can monitor your progress. We'll give you pain relief if you need it. When you're ready to go home, please arrange for someone to collect you as you won't be able to drive. You should have someone stay with you for the first 24 hours.

Before you go home, your consultant will let you know when you can get back to your usual routine (including work), and your medical team will talk to you about staying well.
