Özet
Objective: We aimed to compare the radiological and clinical characteristics of COVID-19-positive and -negative acute ischemic stroke (AIS) patients who underwent revascularization and to evaluate whether COVID-19 has an effect on revascularization and outcome in AIS patients with COVID-19 infection. Methods: Consecutive COVID-19 positive and negative AIS patients who underwent intravenous thrombolysis and/or endovascular therapy in our hospital between March 2020 and February 2022 were included in this study. Our study is retrospective and 23 COVID-19 positive patients and 108 COVID-19 negative patients were compared in terms of radiological and clinical characteristics. Results: Hypertension was lower in the COVID-19 positive ischemic stroke group (p=0.029). Admission NIHSS score was higher in COVID-19 positive patients (p=0.041). ASPECTS was found to be lower in COVID-19 positive ischemic stroke patients (p=0.019). The rate of hyperdense artery sign differed between groups (p=0.014) and was higher in the COVID-19 positive ischemic stroke group. The incidence of multi-vessel occlusion was found to be significantly higher in the COVID-19-positive ischemic stroke group (p=0.002). In terms of prognostic features, only the 3-month good outcome rate was statistically significantly lower in the COVID-19-positive ischemic stroke group (p=0.011). Conclusion: This study found that radiologically, COVID-19 may be associated with lower ASPECTS in ischemic stroke patients receiving revascularization treatment and may predispose to multivessel occlusion and hyperdense artery sign. Clinically, COVID-19 may be associated with a more severe initial presentation and worse prognosis at 3 months in ischemic stroke patients undergoing revascularization, but may not affect long-term mortality.
