8 out of 10 stroke patients who leave the hospital do so with a disability. As a result, stroke costs UK society £26 billion per year. The most severe and disabling strokes are due to a large vessel occlusion (LVO).

The standard of care for LVO stroke in the UK has been the administration of thrombolysis (a clot-busting drug called alteplase). This is only modestly effective for LVO stroke patients, and the majority are dead or disabled at 1 year after their stroke. In 2015 a series of research trials demonstrated the efficacy of mechanical thrombectomy to open the occluded vessel for LVO stroke patients. This has transformed the potential care of patients with LVO stroke: patients who would have ended up in nursing homes are walking out of the hospital the next day. Each thrombectomy is thought to save the economy £80,000.

In the UK fewer than 1% of stroke patients undergo thrombectomy, but it is estimated that over 10% would benefit. The key barrier to delivering this treatment is patient identification due to a lack of real-time neuroradiology imaging expertise at all sites to which stroke patients present, compounded by communication barriers across stroke networks.
