Mechanical thrombectomy in acute ischemic stroke.

Recent randomized trials have demonstrated the efficacy of stent retriever thrombectomy, in association with intravenous thrombolysis, in acute ischemic stroke related to the occlusion of the distal internal carotid artery or the proximal middle cerebral artery within six hours of symptom onset. Mechanical thrombectomy should be performed as soon as possible after symptom onset. High age alone should not be considered as a contraindication for mechanical thrombectomy. Mechanical thrombectomy is recommended in acute ischemic stroke patients with large vessel occlusions and salvageable brain tissue if intravenous thrombolysis is contraindicated. Re-organization of stroke care systems is needed to provide rapid access to endovascular therapy equitably to all eligible patients.
