- Introduction: The Stockholm Stroke Triage System (SSTS) is a prehospital triage system for detection of patients eligible for endovascular thrombectomy (EVT). Assessment of hemiparesis combined with ambulance-hospital teleconsultation is used to route patients directly to the thrombectomy centre. Some patients are not identified and require secondary transport for EVT (undertriage) while others taken to the thrombectomy centre do not undergo EVT (overtriage). The aims of this study were to characterize mistriaged patients, model for and evaluate alternative triage algorithms.Patients and methods: Patients with suspected stroke transported by priority 1 ground ambulance between October 2017 and October 2018 (n = 2905) were included. Three triage algorithms were modelled using prehospital data. Decision curve analysis was performed to calculate net benefit (correctly routing patients for EVT without increasing mistriage) of alternative models vs SSTS.Results: Undertriage for EVT occurred in n = 35/2582 (1.4%) and overtriage in n = 239/323 (74.0%). Compared to correct thrombectomy triages, undertriaged patients were younger and had lower median NIHSS (10 vs 18), despite 62.9% with an M1 occlusion. In overtriaged patients, 77.0% had a stroke diagnosis (29.7% haemorrhagic). Hemiparesis and FAST items face and speech were included in all models. Decision curve analysis showed highest net benefit for SSTS for EVT, but lower for large artery occlusion (LAO) stroke.Discussion: Undertriaged patients had lower NIHSS, likely due to better compensated proximal occlusions. SSTS was superior to other models for identifying EVT candidates, but lacked information allowing comparison to other prehospital scales.Conclusion: Using prehospital data, alternative models did not outperform the SSTS in finding EVT candidates.

- Pregnancy, postpartum and menopause are regarded as periods women are more vulnerable to ischaemic events. There are conflicting results regarding stroke risk and hormone replacement therapy (HRT) during menopause. Stroke in pregnancy is generally increasing with serious consequences for mother and child; therefore, recommendations for acute treatment with intravenous thrombolysis (IVT) and/or mechanical thrombectomy (MT) are needed. The aim of this guideline is to support and guide clinicians in treatment decisions in stroke in women. Following the “Grading of Recommendations and Assessment, Development and Evaluation (GRADE)” approach, the guidelines were developed according to the European Stroke Organisation (ESO) Standard Operating Procedure. Systematic reviews and metanalyses were performed. Based on available evidence, recommendations were provided. Where there was a lack of evidence, an expert consensus statement was given. Low quality of evidence was found to suggest against the use of HRT to reduce the risk of stroke (ischaemic and haemorrhagic) in postmenopausal women. No data was available on the outcome of women with stroke when treated with HRT. No sufficient evidence was found to provide recommendations for treatment with IVT or MT during pregnancy, postpartum and menstruation. The majority of members suggested that pregnant women can be treated with IVT after assessing the benefit/risk profile on an individual basis, all members suggested treatment with IVT during postpartum and menstruation. All members suggested treatment with MT during pregnancy. The guidelines highlight the need to identify evidence for stroke prevention and acute treatment in women in more vulnerable periods of their lifetime to generate reliable data for future guidelines.

- The aim of the present European Stroke Organisation guideline is to provide clinically useful evidence-basedrecommendations on the management of patients with intracranial atherosclerotic disease (ICAD). The guidelines wereprepared following the Standard Operational Procedure of the European Stroke Organisation guidelines and accordingto GRADE methodology. ICAD represents a major cause of ischemic stroke worldwide, and patients affected by thiscondition are exposed to a high risk for future strokes and other major cardiovascular events, despite best medicaltherapy available. We identified 11 relevant clinical problems affecting ICAD patients and formulated the correspondingPopulation Intervention Comparator Outcomes (PICO) questions. The first two questions refer to the asymptomaticstage of the disease, which is being increasingly detected thanks to the routine use of noninvasive vascular imaging. Wewere not able to provide evidence-based recommendations regarding the optimal detection strategy and management ofasymptomatic ICAD, and further research in the field is encouraged as subclinical ICAD may represent a big opportunityto improve primary stroke prevention. The second block of PICOs (3–5) is dedicated to the management of acutelarge vessel occlusion (LVO) ischemic stroke caused by ICAD, a clinical presentation of this disease that is becomingincreasingly relevant and problematic, since it is associated with more refractory endovascular reperfusion procedures.An operational definition of probable ICAD-related LVO is proposed in the guideline. Despite the challenging context,no dedicated randomized clinical trials (RCTs) were identified, and therefore the guideline can only provide withsuggestions derived from observational studies and our expert consensus, such as the escalated use of glycoproteinIIb-IIIa inhibitors and angioplasty/stenting in cases of refractory thrombectomies due to underlying ICAD. The last blockof PICOs is devoted to the secondary prevention of patients with symptomatic ICAD. Moderate-level evidence wasfound to recommend against the use of oral anticoagulation as preferred antithrombotic drug, in favor of antiplatelets.Low-level evidence based our recommendation in favor of double antiplatelet as the antithrombotic treatment of choicein symptomatic ICAD patients, which we suggest to maintain during 90days as per our expert consensus. Endovasculartherapy with intracranial angioplasty and or stenting is not recommended as a treatment of first choice in high-gradesymptomatic ICAD (moderate-level evidence). Regarding neurosurgical interventions, the available evidence does notsupport their use as front line therapies in patients with high-grade ICAD. There is not enough evidence as to provideany specific recommendation regarding the use of remote ischemic conditioning in ICAD patients, and further RCTsare needed to shed light on the utility of this promising therapy. Finally, we dedicate the last PICO to the importanceof aggressive vascular risk factor management in ICAD, although the evidence derived from RCTs specifically addressingthis question is still scarce

- Outcomes after mechanical thrombectomy (MT) in young stroke patients remain elusive due to small patient cohorts. We sought to determine outcomes after MT in stroke patients between ages 18 and 64 years and compare with outcomes in older patients in a large national stroke cohort. Patients and methods We used the Swedish National Stroke Registry and the Swedish National Endovascular Thrombectomy Registry to identify all patients treated with MT for anterior circulation occlusions. We examined outcome measures in terms of functional independence at 90 days (modified Rankin Scale score of 0–2), symptomatic intracerebral hemorrhage (sICH), and mortality at 90 days with multivariable logistic regression analysis. Results Of 2143 patients, 565 were between 18 and 64 years (26.4%) and 1179 (55.0%) were males. Analysis showed that patient aged 18–64 achieved higher rate of functional independence at 90 days (46.2% vs 28.4%, p < .001), had less often sICH (5.5% vs 6.8%, p = .008), and lower 90-day mortality rate (6.9% vs 17.7%, p < .001). Increasing age was associated with a lesser probability of functional independence at 90 days (adjusted odds ratio (aOR), 0.94; [95% confidence intervals (CIs) 0.93–0.95]), higher odds of mortality at 90 days (aOR, 1.05; [95% CIs 1.03–1.06]), and of sICH (aOR 1.03; [95% CIs 1.01–1.05]). Conclusion Patients aged 18–64 years demonstrated better outcome after thrombectomy regarding functional independence, sICH, and mortality at 90 days when compared to older ages.
