Abstrakt: Objectives: Data concerning the results of endovascular thrombectomy (EVT) in old patients is still limited. We aimed to investigate the outcomes in thrombectomytreated ischemic stroke patients aged > 80 years, focusing on frailty as a contributing factor. Patients and methods: We performed a single-centre retrospective cohort study with 159 consecutive patients aged > 80 years and treated with EVT for acute ischemic stroke between January 1st 2016 and December 31st 2019. Pre-admission frailty was assessed with the Clinical Frailty Scale (CFS). Patients with CFS > 5 were defined as frail. The main outcome was very poor outcome defined as mRS 46 at three months after EVT. Secondary outcomes were recanalization status, symptomatic intracerebral haemorrhage (sICH), and one-year survival. Finally, we recorded if the patient returned home within 12 months. Results: Very poor outcome was observed in 57.9% of all patients (52.4% in non-frail and 79.4% in frail patients). Rates of recanalization and sICH were comparable in frail and non-frail patients. Of all patients, 46.5% were able to live at home within 1 year after stroke. One-year survival was 59.1% (65.6% in non-frail and 35.3% in frail patients). In logistic regression analysis higher admission NIHSS, not performing thrombolysis, lack of recanalization and higher frailty status were all independently associated with very poor three-month outcome. Factors associated with one-year mortality were male gender, not performing thrombolysis, sICH, and higher frailty status. Conclusion: Almost 60% of studied patients had very poor outcome. Frailty significantly increases the likelihood of very poor outcome and death after EVT-treated stroke.(c) 2022 The Authors. Published by Elsevier Inc.
