The comparison of mechanical thrombectomy and symptomatic therapy on early outcome of acute ischemic stroke in patients older than 80 years: A retrospective cohort study.

Objective: Multiple randomized trials have confirmed that endovascular thrombectomy (ET) is an effective treatment method for patients with acute ischemic stroke (AIS) caused by large vessel occlusion (LVO). However, patients older than eighty years of age show worse functional outcomes and higher mortality rates after ET. Our retrospective study aimed to confirm the efficacy of ET in older patients and identify characteristics or variables that can be associated with a better or worse outcome of ET.
