A stroke is an dramatic insult to the brain and has to be treated as quickly as possible to have a chance for complete recovery of all neurological functions. The most common cause of a stroke is an occlusion of the artery in form of a clot (thrombus). If this occlusion persists, areas of the brain can be irrevisble damaged due to the lack of blood supply, resulting in chronic neurological deficits. In addition to treatment with clot-busting drugs, it can be beneficial to mechanically remove the thrombus (thrombectomy), thereby re-establishing the blood flow to the affected areas of the brain.
For a successful treatment of stroke, it is essential that the clot is localised and removed within a short period of time after symptom onset.
