Mechanical thrombectomy is indicated for patients who have an acute ischemic stroke caused by a large artery occlusion in the anterior circulation and can be treated within 24 hours of last known good health (ie, at neurologic baseline), regardless of whether they have received intravenous thrombolytic therapy for the same. Mechanical thrombectomy is a minimally invasive technique in which an interventional radiologist removes a clot from a patient's artery using specialised equipment. The doctor uses fluoroscopy, or continuous x-ray, to guide devices through the patient's arteries to the clot, which is then extracted in one piece. For patients with ischemic stroke (IS) who have a proximal major cerebral artery occlusion within 6 hours of onset of symptoms, mechanical thrombectomy (MT) is the standard-of-care treatment.
