Thousands miss out on stroke treatment

About 9,000 stroke patients a year are missing out on a treatment that can prevent disability following a stroke, say UK experts.About 9,000 stroke patients a year are missing out on a treatment that can prevent disability following a stroke, say UK experts.

In the UK, nearly 90,000 people each year are admitted to hospital following a stroke. Clot retrieval can restore blood flow to the brain, preventing some lasting damage, but currently only 600 patients a year get this therapy, they estimate.

A national stroke audit reveals part of the problem is a lack of skilled staff to do the procedure.

During a stroke, the blood supplying vital parts of the brain is interrupted. The most common reason is a clot blocking a major blood vessel in the head, although some strokes are caused by a bleed.

The longer a part of the brain is starved of blood, the more likely lasting damage – such as paralysis and speech problems – will occur.

While many people with a stroke caused by a clot currently get drugs to help dissolve the blockage, this does not always work completely.

Thrombectomy – or clot retrieval – is another method, which aims to remove the clot mechanically. It is a highly skilled operation, and stroke services need to be set up to be able to deliver the treatment.

A thin metal wire housing a mesh is inserted into a major artery in the leg and, under X-ray guidance, it is directed to the site of the problem in the brain.

The mesh is then expanded, like a miniature fishing net, to trap and remove the clot.

Researchers from Newcastle University, Northumbria University, Oxford Academic Health Science Network and the National Institute for Health Research looked at thrombectomy data and stroke statistics in the UK to work out how many patients might benefit from the procedure.

In a presentation given to the UK Stroke Forum national conference, they estimated one in 10 people admitted to a hospital with a stroke could be eligible for thrombectomy.

Investigator Dr Martin James, at the Royal Devon and Exeter Hospital, said: “Delivering the procedure to the 9,000 people who need it will require major changes to the configuration and skill sets of existing acute stroke services.

“We must work quickly to establish what needs to be done so that more people in the UK can benefit from a treatment which can dramatically reduce disability after a stroke as well as cutting associated costs to the NHS and social care.”

Thrombectomy has already been deemed safe and effective by the health watchdog the National Institute of Health and Care Excellence.

NICE says the treatment should be carried out only in places that have trained specialists and the necessary support staff and equipment.
Consultant shortages

The Royal College of Physicians said: “There is a major shortage of appropriately trained staff to undertake thrombectomy, particularly outside of London, and it will take time to train up enough doctors to undertake this skilled procedure.”
