Arterial disease

Arterial disease is when fatty deposits build up in your arteries, restricting blood supply. We treat all aspects of arterial diseases including:

  • Carotid surgery and stroke prevention

  • Aortic aneurysm

  • Ischaemic legs (poor circulation)

  • Diabetic foot problems

  • Bypass surgery for blocked arteries

  • Amputations

  • Upper limb circulation problems, like Thoracic Outlet Syndrome.


Mr Onwudike works with an excellent vascular laboratory, alongside expert interventional radiologists, vascular nurse specialists, vascular anaesthetists, cardiologists, diabetologists and stroke physicians.

The Circulation Foundation has more information on vascular and arterial disease.

Stroke prevention treatment

A stroke can happen when blood supply to the brain has been cut off, preventing your brain from getting oxygen and essential nutrients.

If you have suffered mini-strokes or mild strokes, then we might advise interventions like a timely carotid surgery to tackle the blood clot or plaque build up in the carotid artery. This can prevent a disabling stroke
in the future.

You will stay in our hospital for up to three nights and results tend to be excellent.

Aortic aneurysm treatment

An aortic aneurysm is a bulging of the wall of your body’s main
artery, the aorta. It’s a vital artery, taking blood from your heart all
over your body.

There is a brilliant national screening programme which has reduced
the number of people who have presented with a ruptured aneurysm.

It’s best to repair the bulge before it ruptures, giving 95% of patients an excellent survival rate compared to intervention after rupturing.

We offer both the usual open operation for aneurysms, and, where we can, the minimally-invasive repair of aneurysms using stents or grafts inserted through the groin. This is also known as endovascular repair.

Depending on the treatment type, you might stay in hospital for up to
a week. Most patients can resume their normal activities within a few months of rest and rehabilitation.

Bypass Treatment

Your arteries might have a blockage, which can impact the blood flow
to your limbs.

We can do one of several types of bypass procedures to reroute blood flow around the blockage using some of your own healthier veins, or by using an artificial vein alternative, like a balloon angioplasty or stent.

Depending on treatment, you might stay in hospital for a few days. Most patients can resume their normal activities within three months of rest and rehabilitation.

Diabetic foot treament

Some people with diabetes might develop complications of diabetic
foot infections, ulcers and gangrene, requiring expert vascular surgical interventions.

We work with you through a series of assessments and investigations
to decide whether an open and minimally-invasive procedure is best
to treat your foot.

In extreme cases, some people with diabetes might only benefit from
an amputation if the condition has gone untreated for some time.

In this rare case, we will provide an excellent rehabilitation programme and artificial limb services to coach you through that difficult time.

Stents and balloons

You might have heard the word ‘stent’ used in your treatment options. This small device is inserted into your artery to widen it where you have a blockage.

There’s only a 10-15% chance your artery would narrow again after a stent has been inserted.

A balloon angioplasty is a balloon inserted by catheter into the artery and inflated to widen the narrow part.

Both are relatively painless, very common procedures.
