Introduction Recent exploratory analysis suggested comparable outcomes among stroke patients undergoing endovascular therapy (EVT) for anterior circulation large vessel occlusion, whether selected via the telestroke network or admitted directly to an EVT-capable centre. We further studied the role of telemedicine in selection of ischaemic stroke patients potentially eligible for EVT. Methods We prospectively included consecutive ischaemic stroke patients with anterior circulation large vessel occlusion who underwent EVT at our neurovascular centre (January 2016 to March 2018). We compared safety and efficacy including symptomatic intracerebral haemorrhage (sICH), successful reperfusion (mTICI 2b/3), 90-day favourable outcome (mRS ≤ 2) and 90-day survival between patients transferred from telestroke hospitals and patients directly admitted. Results Of 280 potentially EVT-eligible patients, 72/129 (56%) telestroke and 91/151 (60%) direct admissions eventually underwent EVT (age 76 (66–82) years, median (interquartile range), 46% men, NIHSS score 17 (13–20)). Telestroke patients had larger pre-EVT infarct cores (ASPECTS: 7 (6–8) vs. 8 (7–9); p < 0.0001) and shorter door-to-groin puncture times (71 (56–84) vs. 101 (79–133) min; p < 0.0001) than directly admitted patients. sICH (2.8% vs. 1.1%; p = 0.58), successful reperfusion (81% vs. 77%; p = 0.56), 90-day favourable outcome (25% vs. 29%; p = 0.65) and 90-day survival (73% vs. 67%; p = 0.39) rates were comparable among telestroke and direct admissions. Discussion Our data underpins the important role of telemedicine in identifying acute ischaemic stroke patients lacking immediate access to EVT-capable stroke centres. Stroke patients selected via telemedicine and those directly admitted had comparable chances of favourable outcomes after EVT for large vessel occlusion.

<b><i>Introduction:</i></b> Treatment of patients with acute large vessel occlusion (LVO) stroke is highly time dependent. MRI and CT are both used as primary neuroimaging modalities in these patients, which may be associated with differences in workflow times of endovascular therapy (ET), thus potentially affecting clinical outcome. We here aimed to compare workflow times and clinical outcome in a large cohort of patients initially examined by MRI or CT. <b><i>Methods:</i></b> We analyzed patients who underwent ET between 2015 and 2019 and were enrolled into the prospective multicenter German Stroke Registry-Endovascular Therapy (GSR-ET). Patients who had an MRI prior to ET were compared to patients with a pretreatment CT regarding baseline data, in-hospital workflow times, and clinical outcome. <b><i>Results:</i></b> Three hundred seventy out of 4,638 patients were examined with an initial MRI (8.0%). Compared to patients with an initial CT, MRI patients had a longer median time from hospital admission to imaging acquisition (23 vs. 14 min). All consecutive workflow times did not significantly differ between both groups after adjustment for confounders. Moreover, the clinical outcome did not differ between MRI and CT patients after adjustment for confounders. <b><i>Conclusion:</i></b> In LVO stroke patients undergoing ET, pretreatment imaging with MRI instead of CT leads to a delay of imaging acquisition after hospital admission without having a measurable impact on consecutive workflow steps and clinical outcome.

Background and aims: To investigate whether stroke aetiology affects outcome in patients with acute ischaemic stroke who undergo endovascular therapy. Methods: We retrospectively analysed patients from the Bernese Stroke Centre Registry (January 2010–September 2018), with acute large vessel occlusion in the anterior circulation due to cardioembolism or large-artery atherosclerosis, treated with endovascular therapy (±intravenous thrombolysis). Results: The study included 850 patients (median age 77.4 years, 49.3% female, 80.1% with cardioembolism). Compared with those with large-artery atherosclerosis, patients with cardioembolism were older, more often female, and more likely to have a history of hypercholesterolaemia, atrial fibrillation, current smoking (each p < 0.0001) and higher median National Institutes of Health Stroke Scale (NIHSS) scores on admission ( p = 0.030). They were more frequently treated with stent retrievers ( p = 0.007), but the median number of stent retriever attempts was lower ( p = 0.016) and fewer had permanent stent placements ( p ⩽ 0.004). Univariable analysis showed that patients with cardioembolism had worse 3-month survival [72.7% versus 84%, odds ratio (OR) = 0.51; p = 0.004] and modified Rankin scale (mRS) score shift ( p = 0.043) and higher rates of post-interventional heart failure (33.5% versus 18.5%, OR = 2.22; p < 0.0001), but better modified thrombolysis in cerebral infarction (mTICI) score shift ( p = 0.025). Excellent (mRS = 0–1) 3-month outcome, successful reperfusion (mTICI = 2b–3), symptomatic intracranial haemorrhage and Updated Charlson Comorbidity Index were similar between groups. Propensity-matched analysis found no statistically significant difference in outcome between stroke aetiology groups. Stroke aetiology was not an independent predictor of favourable mRS score shift, but lower admission NIHSS score, younger age and independence pre-stroke were (each p < 0.0001). Stroke aetiology was not an independent predictor of heart failure, but older age, admission antithrombotics and dependence pre-stroke were (each ⩽0.027). Stroke aetiology was not an independent predictor of favourable mTICI score shift, but application of stent retriever and no permanent intracranial stent placement were (each ⩽0.044). Conclusion: We suggest prospective studies to further elucidate differences in reperfusion and outcome between patients with cardioembolism and large-artery atherosclerosis.

AbstractThe prominent vessel sign (PVS) on susceptibility-weighted imaging (SWI) is not displayed in all cases of acute ischemia. We aimed to investigate the factors associated with the presence of PVS in stroke patients. Consecutive ischemic stroke patients admitted within 24 h from symptom onset underwent emergency multimodal MRI at admission. Associated factors for the presence of PVS were analyzed using univariate analyses and multivariable logistic regression analyses. A total of 218 patients were enrolled. The occurrence rate of PVS was 55.5%. Univariate analyses showed significant differences between PVS-positive group and PVS-negative group in age, history of coronary heart disease, baseline NIHSS scores, total cholesterol, hemoglobin, anterior circulation infarct, large vessel occlusion, and cardioembolism. Multivariable logistic regression analyses revealed that the independent factors associated with PVS were anterior circulation infarct (odds ratio [OR] 13.7; 95% confidence interval [CI] 3.5–53.3), large vessel occlusion (OR 123.3; 95% CI 33.7–451.5), and cardioembolism (OR 5.6; 95% CI 2.1–15.3). Anterior circulation infarct, large vessel occlusion, and cardioembolism are independently associated with the presence of PVS on SWI.

Introduction: Five RCTs demonstrated the superiority of endovascular therapy (EVT) over best medical management (MM) for acute ischemic strokes (AIS) with large vessel occlusion (LVO) in the anterior circulation. Patients with M2 occlusions, however, were underrepresented (95 randomized; 51 EVT treated). Evidence from RCTs of the benefit of EVT for M2 occlusions is lacking, as reflected in the recent AHA guidelines. Methods: A retrospective cohort was pooled from 10 academic centers from 1/12 to 4/15 of AIS patients with LVO isolated to M2 presenting within 8 hours from last known normal (LKN). Patients were divided into EVT and MM groups. Primary outcome was 90 day mRS (good outcome 0-2); secondary outcome was sICH. Logistic regression compared the 2 groups. Univariate and multivariate analyses evaluated predictors of good outcome in the EVT group. Results: Figure 1 shows participating centers, 522 patients (288 EVT and 234 MM) were identified. Table (1) shows baseline characteristics. MM treated patients were older and had higher IV tPA treatment rates, otherwise the 2 groups were balanced. 62.7 % EVT patients had mRS 0-2 at 90 days compared to 35.4 % MM (figure 2). EVT patients had 3 times the odds of good outcome as compared to MM patients (OR: 3.1, 95% CI:2.1-4.4, P <0.001) even after adjustment for age, NIHSS, ASPECTS, IV tPA and LKN to door time (OR: 3.2, 95%CI: 2-5.2, P<0.001). sICH rate was 5.6 %, which was not statistically different than the MM group (table 1, P=0.1). Age, NIHSS, good ASPECTS, LKN to reperfusion time and successful reperfusion mTICI ≥ 2b were independent predictors of good outcome in EVT patients. There was a linear relationship between good outcome and time LKN to reperfusion (Figure 3). Conclusion: Despite inherent limitations of its retrospective design, our study suggests that EVT may be effective and safe for distal LVO (M2) relative to best MM. A trial randomizing M2 occlusions to EVT vs. MM is warranted to confirm these findings.
