While any blood clot can cause major issues, a 2017 study has shown that thrombectomy treatment within 24 hours after an acute stroke can result in a 73% lower risk of disability.
Recovery will vary widely and will depend on individual health and conditions, and a thrombectomy will not prevent the chance of another blood clot forming again. Consult your doctor about any lifestyle changes and medication that may be prescribed following a thrombectomy to help encourage long-term health improvements.
