    Abstract Over the past 20 years, ultrasonic cerebral perfusion imaging (UPI) has been introduced and validated applying different data acquisition and processing approaches. Clinical data were collected mainly in acute stroke patients. Some efforts were undertaken in order to compare different technical settings and validate results to gold standard perfusion imaging. This review illustrates the evolution of the method, explicating different technical aspects and milestones achieved over time. Up to date, advancements of ultrasound technology as well as data processing approaches enable semi-quantitative, gold standard proven identification of critically hypo-perfused tissue in acute stroke patients. The rapid distribution of CT perfusion over the past 10 years has limited the clinical need for UPI. However, the unexcelled advantage of mobile application raises reasonable expectations for future applications. Since the identification of intracerebral hematoma and large vessel occlusion can also be revealed by ultrasound exams, UPI is a supplementary multi-modal imaging technique with the potential of pre-hospital application. Some further applications are outlined to highlight the future potential of this underrated bedside method of microcirculatory perfusion assessment.

    Abstract Aim and methods: To analyse nationwide changes in neurointerventional center size of all German hospitals performing mechanical thrombectomy (MT) in stroke patients from 2016 to 2019. Furthermore, we assessed cross-district patient migration for MT for the first time using hospitals' structured quality reports and German Diagnosis-Related Groups data in 2019.
    Findings: Number of hospitals performing more than 100 MT procedures/year doubled in Germany from 2016 (n = 36) to 2019 (n = 71), and these neurointerventional centers performed 71% of all MT procedures in 2019. The overall increase in MT procedures was largely driven by these high-volume neurointerventional centers with ability to perform MT 24/7 (121% increase as compared with 8% increase in hospitals performing less than 100 MT procedures/year). The highest cross-district patient mobility/transfer of stroke patients for MT was observed in districts adjacent to these high-volume neurointerventional centers with existing neurovascular networks.
    Conclusion: The substantial increase in MT procedures observed in Germany between 2016 and 2019 was almost exclusively delivered by high-volume stroke centers performing more than 100 MT procedures per year in established neurovascular networks. As there is still a reasonable number of districts with low MT rates, further structural improvement including implementation of new or expansion of existing neurovascular networks and regional tailored MT triage concepts is needed.

  7. Article ; Online: The level of urbanization influences acute ischemic stroke care: A nationwide ecological study from Germany.

    Abstract Background and purpose: Regional differences in acute ischemic stroke (AIS) care are still reported for Germany but not fully understood. We aimed to analyze the impact of the level of urbanization on the application of proved treatment procedures and the incidence of hospitalized AIS cases in Germany.
    Methods: The level of urbanization of the 401 districts and district-free cities in Germany was defined according to the Federal Institute for Building, Urban Affairs and Spatial Research classification. Using nationwide administrative data, the application of intravenous thrombolysis (IVT), mechanical thrombectomy (MT), and the incidence of hospitalizations for AIS, were analyzed according to the place of residence of the patients. Data included all patients hospitalized for AIS in 2019 (n = 224,274) and sociodemographic information of 83,019,213 residents in Germany.
    Results: Sparsely populated districts had a significantly higher incidence of hospitalizations for AIS than cities (age-standardized: 271.8 versus 242.3 per 100,000 inhabitants, P < 0.001), but a lower use of MT (5.7% versus 8.4%, P < 0.001). In the adjusted negative binomial regression model, rurality remained an independent predictor for MT use and the incidence of AIS hospitalizations. The proportion of IVT did not significantly differ between sparsely populated districts and cities (15.6% versus 17.2%, P = 0.021).
    Conclusions: Although there is a dense network of stroke units in Germany, the level of urbanization still influences AIS care, as we found a lower proportion of MT and a higher incidence of AIS hospitalizations in Germany's rural areas.

    Abstract Background and purpose: Many countries worldwide, including Germany, reported that the first wave of the coronavirus disease 2019 (COVID-19) pandemic in early 2020 influenced the care of acute ischemic stroke (AIS) patients, but data are lacking for further pandemic wave periods.
    Methods: We conducted a nationwide, retrospective, cross-sectional study of all hospitalized patients with the main diagnosis of AIS in 2019 and 2020. Primary outcomes were the number of hospitalizations for AIS, the application of stroke unit care, intravenous thrombolysis (IVT), and mechanical thrombectomy (MT), as well as the in-hospital mortality during the different pandemic periods in 2020 compared to the corresponding periods in 2019. Secondarily, we analyzed differences in outcomes between patients with and without concurrent COVID-19.
    Results: We included 429,841 cases with AIS, of which 1268 had concurrent COVID-19. Hospitalizations for AIS declined during both pandemic wave periods in 2020 (first wave: -10.9%, second wave: -4.6%). MT rates were consistently higher throughout 2020 compared to 2019, whereas the IVT rate dropped during the second wave period (16.0% vs. 17.0%, p < 0.001). AIS patients with concurrent COVID-19 frequently received recanalization treatments, with an overall MT rate of 8.4% and IVT rate of 15.9%. The in-hospital mortality was high (22.8% vs. 7.5% in noninfected AIS patients, p < 0.001).
    Conclusions: These findings demonstrate a smaller decline in hospitalizations for AIS in the more severe second wave of the COVID-19 pandemic. AIS patients with and without concurrent COVID-19 who did seek acute care continued to receive recanalization treatments in Germany.
