Stroke admission outside daytime working hours delays mechanical thrombectomy and worsens short-term outcome.

Treatment outside regular working hours caused a significant delay in the initiation of MT, which was associated with a decreased short-term clinical efficacy of thrombectomy. Strategies like compulsory attendance of the interventional neuroradiologist at the hospital 24/7 might result in shorter door-to-groin times and consecutive in better stroke outcome.
