Stroke occurs when the blood supply to part of the brain is interrupted, causing brain injury. Ischaemic stroke may result from a blood clot blocking an artery, while haemorrhagic stroke involves bleeding in or around the brain. Mechanical thrombectomy is a procedure used in selected patients with acute ischaemic stroke to remove a clot from a blocked artery.
