Background and Purpose: Biological sex is known to have an impact on quality metrics of acute stroke. We aimed to determine whether COVID positivity accentuates this effect and constitutes worse outcome., Methods: The present analysis was based on the Global COVID-19 Stroke Registry, a retrospective, international, cohort study of consecutive ischemic stroke patients receiving intravenous thrombolysis and/or endovascular thrombectomy between 1 March 2020 and 30 June 2021. We investigated differences between the sexes in patient characteristics, acute stroke metrics as well as post-stroke outcome in COVID-positive and COVID-negative stroke patients undergoing acute revascularization procedures., Results: A total of 15,128 patients from 106 centers were recorded in the Global COVID-19 Stroke Registry, 853 (5.6%) of whom were COVID-positive. Overall, COVID-positive individuals were treated significantly slower according to every acute stroke metric compared to COVID-negative patients. We were able to show that key quality indicators in acute stroke treatment were unfavorable for COVID-negative women compared to men (last-seen-well-to-door time + 11 min in women). Furthermore, COVID-negative women had worse 3-month outcomes (3-month modified Rankin Scale score [interquartile range] 3.0 [4.0] vs. 2.0 [3.0]; p < 0.01), even after adjusting for confounders. In COVID-positive individuals no such difference between the sexes, either in acute management metrics or in 3-month outcome, was seen., Conclusion: Known sex-related differences in acute stroke management exist and extend to times of crisis. Nevertheless, if patients were COVID-19-positive at stroke onset, women and men were treated the same, which could be attributed to structured treatment pathways., (© 2024 The Authors.

Even though cervical artery dissection is one of the main reasons for ischemic stroke in young patients, acute management and post-acute primary or secondary prevention of cerebral ischemia differ significantly in different centers and countries. These discrepancies are reflected by the differences in guideline recommendations of major stroke societies. Our narrative review aims to shed light on the different recommendations in guideline-statements of stroke societies and to give an overview of the current literature concerning acute management and post-acute treatment of cervical artery dissection patients. In general, intravenous thrombolysis and mechanical thrombectomy are recommended, irrespective of stroke etiology, if administered within the label. Secondary prevention of cerebral ischemia can be achieved by antiplatelet intake or anticoagulation, with, to date, neither treatment establishing superiority over the other. Duration of antithrombotic treatment, statin use as well as optimal endovascular approach are still up for debate and need further evaluation. Additionally, it is still unknown, whether the recommendations given in any of the guideline statements are similarly relevant in spontaneous and traumatic cervical artery dissection, as none of the stroke societies differentiates between the two., Competing Interests: The authors declare no conflict of interest., (© 2022 The Author(s).
