<b><i>Introduction:</i></b> Admission hyperglycemia is an indicator of poor functional prognosis in acute stroke, but investigations of its prevalence and effects on the outcomes of acute large vessel occlusion in real-world, large-scale studies are limited, especially in Asian population. <b><i>Objective:</i></b> We aimed to elucidate the relationship between admission hyperglycemia and outcomes in a prospective multicenter registry in Japan. <b><i>Methods:</i></b> We analyzed data from the Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism (RESCUE) Japan Registry 2, which was a prospective, multicenter registry that enrolled patients from 46 centers in Japan. Admission hyperglycemia was defined as blood glucose level &#x3e;140 mg/dL. The relationships between clinical outcomes and admission hyperglycemia were analyzed in all 1,932 assessable patients. A favorable functional outcome, defined as a modified Rankin Scale score of 0–2 at day 90, as well as mortality within 90 days and symptomatic intracranial hemorrhage (SICH) within 72 h, was analyzed. We performed subgroup analyses of the adjusted variables to investigate the association between hyperglycemia and favorable outcome in relation to each variable. <b><i>Results:</i></b> Admission hyperglycemia was present in 687 (35.6%) of the assessable patients and in 420 (26.9%) of the 1,561 patients without diabetes. A favorable outcome was significantly less frequent in the hyperglycemia group than in the no-hyperglycemia group (33.2% vs. 47.6%, adjusted odds ratio [OR]: 0.60, 95% confidence interval [CI]: 0.47–0.76). The mortality rates were 12.8% and 6.8% in the hyperglycemia and no-hyperglycemia groups, respectively. The incidence of SICH within 72 h was higher in the hyperglycemia group than in the no-hyperglycemia group (4.4% vs. 1.9%, adjusted OR: 2.54, 95% CI: 1.36–4.82). Hyperglycemia was associated with unfavorable outcomes in almost all subgroups. <b><i>Conclusions:</i></b> Admission hyperglycemia in Japanese patients with large vessel occlusion stroke is associated with an unfavorable functional outcome at 90 days, mortality within 90 days, and the occurrence of SICH within 72 h.

Background: Previous studies have demonstrated the efficacy of the “drip-and-ship” model in acute ischemic stroke (AIS) patients treated with intravenous (IV) thrombolysis. We investigated and report the outcomes of the safety and efficacy of the “drip-and-ship” model in AIS patients with acute large-vessel occlusion (LVO) in the anterior circulation who underwent endovascular treatment. Methods: A total of 92 AIS patients with LVO who underwent endovascular treatment enrolled from April 2017 to July 2018 at a single academic comprehensive stroke center (CSC) were included. Patients were divided into 2 groups: a front-door group (directly admitted to the CSC) and a drip-and-ship group (transferred to the CSC from other hospital). Logistic regression model was used to evaluate the functional outcome, mortality, and symptomatic intracranial hemorrhage (sICH) at 90 days. Results: After adjusting for age, gender, occlusion site, National Institutes of Health Stroke Scale (NIHSS) score, and other potential covariates, we did not see difference in modified Rankin Scale (mRS) score between the 2 groups at 90 days. The rate of excellent functional outcome (defined as mRS 0–1) in the drip-and-ship group is lower than the front-door group (p = 0.017); however, functional outcomes (defined as mRS 0–2) have no difference (p = 0.117). There was no significant difference in sICH (p = 0.909) and mortality (p = 0.319) between the 2 groups. Conclusions: The “drip-and-ship” model has the potential to be a feasible model for patients with LVO in the anterior circulation to undergo endovascular treatment. Further large-scale prospective studies are warranted to confirm these findings.

<b><i>Background and Purpose:</i></b> Randomized controlled trials have demonstrated the importance of time to endovascular therapy (EVT) in clinical outcomes in large vessel occlusion (LVO) acute ischemic stroke. Delays to treatment are particularly prevalent when patients require a transfer from hospitals without EVT capability onsite. A computer-aided triage system, Viz LVO, has the potential to streamline workflows. This platform includes an image viewer, a communication system, and an artificial intelligence (AI) algorithm that automatically identifies suspected LVO strokes on CTA imaging and rapidly triggers alerts. We hypothesize that the Viz application will decrease time-to-treatment, leading to improved clinical outcomes. <b><i>Methods:</i></b> A retrospective analysis of a prospectively maintained database was assessed for patients who presented to a stroke center currently utilizing Viz LVO and underwent EVT following transfer for LVO stroke between July 2018 and March 2020. Time intervals and clinical outcomes were compared for 55 patients divided into pre- and post-Viz cohorts. <b><i>Results:</i></b> The median initial door-to-neuroendovascular team (NT) notification time interval was significantly faster (25.0 min [IQR = 12.0] vs. 40.0 min [IQR = 61.0]; <i>p</i> = 0.01) with less variation (<i>p</i> &#x3c; 0.05) following Viz LVO implementation. The median initial door-to-skin puncture time interval was 25 min shorter in the post-Viz cohort, although this was not statistically significant (<i>p</i> = 0.15). <b><i>Conclusions:</i></b> Preliminary results have shown that Viz LVO implementation is associated with earlier, more consistent NT notification times. This application can serve as an early warning system and a failsafe to ensure that no LVO is left behind.

Background There is an ongoing debate on the off-hour effect on endovascular treatment (EVT) for acute large vessel occlusion (LVO). Aims This meta-analysis aimed to compare time metrics and clinical outcomes of acute LVO patients who presented/were treated during off-hour with those during working hours. Summary of review Structured searches on the PubMed, Embase, Web of Science, and Cochrane Library databases were conducted through February 23rd, 2021. The primary outcomes were onset to door, door to imaging, door to puncture, puncture to recanalization, procedural time, successful recanalization, symptomatic intracerebral hemorrhage (SICH), mortality in hospital, good prognosis (90-day modified Rankin Scale [mRS] score 0-2), and 90-day mortality. The secondary outcomes were imaging to puncture, onset to puncture, onset to recanalization, door to recanalization time, mRS 0-2 at discharge, and consecutive 90-day mRS score. The odds ratio (OR) and weighted mean difference (WMD) with 95% confidence interval (CI) of the outcomes were calculated using random-effect models. Heterogenicity and publication bias were analyzed. Subgroup and sensitivity analyses were conducted as appropriate. Nineteen studies published between 2014 and 2021 with a total of 14185 patients were eligible for quantitative synthesis. Patients in the off-hour group were significantly younger than those in the on-hour group and with comparable stroke severity and intravenous thrombolysis rate. The off-hour group had longer onset to door (WMD [95%CI], 12.83 [1.84-23.82] min), door to puncture (WMD [95%CI], 11.45 [5.93-16.97] min), imaging to puncture (WMD [95%CI], 10.39 [4.61-16.17] min), onset to puncture (WMD [95%CI], 25.30 [13.11-37.50] min), onset to recanalization (WMD [95%CI], 25.16 [10.28-40.04] min), and door to recanalization (WMD [95%CI], 18.02 [10.01-26.03] min) time. Significantly lower successful recanalization rate (OR [95%CI], 0.85 [0.76-0.95]; P=0.004; I2=0%) was detected in the off-hour group. No significant difference was noted regarding SICH and prognosis. But a trend towards lower OR of good prognosis was witnessed in the off-hour group (OR [95%CI], 0.92 [0.84-1.01]; P=0.084; I2=0%). Conclusions Patients who presented/were treated during off-hour were associated with excessive delays before the initiation of EVT, lower successful reperfusion rate, and a trend towards worse prognosis when compared with working hours. Optimizing the workflows of EVT during off-hour is needed.

Introduction : Acute large vessel occlusion (LVO) can be secondary to thromboembolism or underlying intracranial atherosclerotic disease (ICAD). Data on the management of LVO due to underlying ICAD are scarce. We hypothesized that patients with ICAD would have worse clinical outcomes following mechanical thrombectomy (MT) than those without ICAD. Methods : We performed a retrospective analysis of consecutive patients who underwent MT for LVO in a large academic comprehensive stroke center between 01/2018 and 05/2021. Presence of underlying ICAD at the site of LVO was determined by the treating interventionalist. We compared outcomes including in‐hospital mortality and 90‐day modified Rankin Scale (mRS) between those with and without underlying ICAD, adjusting for relevant covariates using logistic regression. Results : Among 195 patients (mean age 67.4+15.1 years, 56.9% female, 81% black, median NIHSS score 15), underlying ICAD was present in 39 (20.0%). Stent‐retrievers were used 196 patients with only 3 having rescue stent placement. There were no significant differences in baseline factors amongst the two groups except diabetes was more common (69.2% vs. 49.7%, p = 0.028) and intravenous thrombolysis provided less often (17.9% vs. 36.5%, p = 0.027) in those with ICAD. TICI 2B or higher was achieved in 82.1% of ICAD compared with 94.3% of non‐ICAD patients (p = 0.012). Mortality was more common (50.0% vs. 30.8%, p = 0.025) and good functional outcome (mRS 0–2) at 90 days was less common (10.8% vs. 30.0%, p = 0.002) in the ICAD group. Adjusting for age, diabetes, intravenous thrombolysis, baseline NIHSS score, and final TICI score, underlying ICAD was an independent predictor of mRS 0–2 at 90 days (OR 4.5, 95% CI 1.4‐14.2, p = 0.010). Conclusions : Underlying ICAD is associated with 4.5‐fold increase in poor functional outcome in patients with LVO undergoing traditional MT. Further research is needed to understand factors associated with poor outcomes investigate alternative interventional approaches and medical management in this high‐risk population.

BACKGROUND The authors presented their experience with a case of repeat thrombectomy in a 93-year-old patient who showed a favorable outcome after recurrent large vessel occlusion treated with emergency mechanical thrombectomy. OBSERVATIONS Mechanical thrombectomy has been proven to be effective in treating large vessel occlusion types of ischemic stroke. Most of the patient populations involved in the thrombectomy-related studies were younger than 80 years. In addition, recurrent mechanical thrombectomy is not a common procedure in clinical practice. This unusual case demonstrated the potential to achieve a favorable outcome with thrombectomy even in a patient older than 85 years with recurrent large vessel occlusion. LESSONS There can be a favorable neurological outcome after one or repeat thrombectomies for geriatric patients older than 90 years, and age should not be a deterrent to treatment.

Background and Purpose: Acute ischemic stroke due to large vessel occlusion is associated with a poor prognosis. With no consensus about the best treatment option, various treatment modalities including conservative management, intravenous tissue plasminogen activator, and endovascular approach are currently being used. Methods: Retrospective data including demographic information, baseline NIHSS score, site of occlusion (based on CTA, MRA or angiogram), type of treatment and clinical outcomes were collected from 4 centers in the United States during the period of 2010-2011. Results: A total of 423 were included in final analysis: 175 patients received conservative medical management, 54 patients received intravenous (IV) thrombolysis alone, and 194 patients had endovascular treatment (with or without prior IV tPA). Younger patients were more likely to receive endovascular treatment (p<0.001). There was no statistically significant difference among the sex and co-morbid conditions among the three groups. Proximal middle cerebral artery was the most commonly involved vessel. Strokes due to basilar artery occlusion or internal carotid artery occlusion were associated with worst outcomes in all three groups. Conservative medical management had the lowest rates of symptomatic intracerebral hemorrhage but also the highest mortality rates at 3 months. Patients who received endovascular treatment within the first 3 hrs had better outcome and lower mortality rates as compared to patients with intervention during 3-8 hours or beyond 8 hrs. Conclusions: Our study represents real world experience on the management and outcomes of acute ischemic strokes due to large vessel occlusion. Our results help understand natural history of strokes with large vessel occlusion, as well as modern trends in managing these patients with intravenous and intraarterial treatment approaches.

The Impact

Introduction: CTP and MRI are increasingly used to assess endovascular thrombectomy (EVT) candidacy in large vessel occlusion stroke. Unfortunately, availability of these advanced neuroimaging techniques is not widespread and this can lead to over-triage to EVT-capable centers. Hypothesis: ASPECTS scoring applied to computed tomography angiography source images (CTA-SI) will be predictive of final infarct volume (FIV) and functional outcome. Methods: We reviewed data from consecutive patients undergoing EVT at our institution for anterior circulation occlusion between 01/14 - 01/19. We recorded demographics, comorbidities, NIHSS, treatment time parameters, and outcomes as defined by mRS (0-2 = good outcome). Cerebrovascular images were assessed by outcome-blinded raters and collateral score, TICI score, FIV, and both CT and CTA-SI ASPECTS scores were noted. Patients were grouped by ASPECTS score into low (0-4), intermediate (5-7), and high (8-10) for some analyses. FIV was predicted using a linear regression with NIHSS, good reperfusion (TICI 2b/3), collateral score, CT to groin puncture, CT and CTA-SI ASPECTS as independent variables. After excluding those with baseline mRS≥2, a binary logistic regression was performed including covariates of age, NIHSS, good reperfusion, and diabetes (factors significant at p<0.05 on univariate analysis) to assess the impact of CTA-SI ASPECTS group on outcome. Results: Analysis included 137 patients for FIV and 102 for outcome analysis (35 excluded for baseline mRS≥ 2). Linear regression found CTA-SI ASPECTS (Beta -10.8, p=0.002), collateral score (Beta -42.9, p=0.001) and good reperfusion (Beta 72.605, p=0.000) were independent predictors of FIV. Relative to the low CTA-SI ASPECTS group, the high CTA-SI ASPECTS group was more likely to have good outcome (OR 3.75 [95% CI 1.05-13.3]; p=0.41). CT ASPECTS was not predictive of FIV or good outcome. Outcomes: In those undergoing EVT for anterior circulation occlusion, CTA-SI ASPECTS is predictive of both FIV and functional outcome, while CT ASPECTS predicts neither. CTA-SI ASPECTS holds promise as a lower-cost, more widely available option for triage of patients with large vessel occlusion. Further study is needed comparing CTA-SI ASPECTS to CTP parameters.

Background: COVID-19 has been shown to induce a hypercoagulable state thereby increasing the risk of arterial thrombosis resulting in Large Vessel Occlusion Stroke (LVOs) Objective: We performed a systematic review of published reports to study the clinical characteristics, and outcomes of COVID-19 acute ischemic stroke (AIS) patients with LVO treated with mechanical thrombectomy (MT) and compared them with historical controls. Methods: We conducted a systematic literature search from December 2019 to July 2020 using multiple combinations of keywords from PubMed and Ovid databases according to the PRISMA meta-analyses and systemic reviews guidelines and then pooled data from individual case series. We included studies where COVID -19 associated LVO cases were treated with MT and their clinical outcomes were reported. We then compared these findings with the historic patient data from the five landmark randomized MT trials, the Hermes collaborators (HC). Results: An initial search generated 12 studies but after excluding case reports and multiple reports comprising of the same series of patients, a total of five reports consisting of 51 patients were analyzed. The mean age of patients was 59 years (IQR 36-75), and 40 (78 %) were men. Median NIHSS on presentation was 20 (IQR 10-29). AIS with LVO was the presenting manifestation of COVID-19 in 16 (20%) of patients. Intracranial ICA was the most common site of occlusion found in 27 (53%) of patients with multi-territory occlusion in 10 (20 %). Final recanalization TICI ≥ 2b was achieved in 33 (64%) of patients but reocclusion was noted in 7 (14 %). Modified Rankin score (mRS) 0-2 was reported in 12 (23 %) of patients with 40 % in-hospital mortality. When compared to historic data from HC, COVID -19 patients were younger (59 vs 69 years), presented with a higher median NIHSS score (20 vs 17), and had a higher prevalence of ICA terminus occlusion (53% vs 21% ). Similarly, patient outcomes were poor in the COVID -19 group with mRs 0-2 in (23 % versus 46 %) and mortality (40 % vs 15 %) compared to Hermes group. Conclusion: COVID -19 AIS patients with LVO who underwent MT were younger, had multiple territory occlusions with a propensity for ICA terminus location, and had poor angiographic and clinical outcomes as compared to historic data.

Introduction: Various scales have been developed to predict long-term clinical outcome after endovascular therapy (EVT) in stroke patients. The objective of this study was to validate and compare five well-validated scales in terms of predictive accuracy for functional independence in a recent endovascular stroke trial (REVASCAT). Hypothesis: We hypothesize that predictive scales (PRE, THRIVE, HIAT2, SPAN-100, FAR) have good-excellent (AUC>0.7) predictive accuracy for good functional outcome and can predict the beneficial effect of EVT demonstrated in randomized clinical trials. Methods: REVASCAT (Randomized Trial of Revascularization with Solitaire-FR Device versus Best Medical Therapy in the Treatment of Acute Stroke Due to Anterior Circulation Large Vessel Occlusion Presenting within Eight Hours of Symptom Onset) enrolled 206 patients who were randomized to receive EVT or best medical treatment. Five scores (PRE-score, THRIVE, HIAT2, SPAN-100 and FAR-score) were retrospectively calculated on patients who received EVT. Receiver-operator characteristics (ROC) for good outcome (mRS 0-2 at 90 days) for each scale were compared. Using the highest predictive scales, the proportion of patients with good outcome by the score categorized in quartiles was analyzed. Results: 103 patients received EVT in the REVASCAT trial (mean age 65.7, median NIHSS 17). Baseline NIHSS, baseline CT-ASPECTS, age and atrial fibrillation, but not previous iv tPA or DM, were associated with good outcome in multivariable analysis. AUC for good outcome was ≥0.70 for FAR (0.74) and PRE (0.70) scores while SPAN-100 (0.67), HIAT2 (0.65) and THRIVE (0.64) had lower AUCs although differences were not statistically significant. The higher the score on the PRE and FAR scores, the lower the proportion of patients with good outcome (PRE-score: 1QT 44.4%, 2QT 24.4%, 3QT 22.2%, 4 QT 8.9%; FAR-score: 1QT 57.8%, 2QT 22.2%, 3QT 6.7%, 4QT 3.3%). Benefit of EVT accordingly to the score on the different scales will be also presented. Conclusions: Of the 5 stroke scales, FAR and PRE had better predictive accuracy for functional independence after EVT. These tools may facilitate decision making for EVT in anterior circulation large vessel occlusion stroke.
