J Stroke Cerebrovasc Dis 2024; 33:107721. [PMID: 38616013 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 04/10/2024] [Accepted: 04/11/2024] [Indexed: 04/16/2024] Open
Abstract
OBJECTIVE Endovascular therapy (EVT) is recommended for patients with acute large-vessel occlusion (LVO) However, its efficacy and safety compared to medical management (MM) in patients with a National Institutes of Health Stroke Scale (NIHSS) score of ≤6 remains unclear. This meta-analysis compared EVT with medical MM in patients with large vessel occlusion mild stroke treated between 2015 and 2023, following the publication of the first randomized controlled trial. MATERIALS AND METHODS Biomedical database searches (inception to March 21, 2023) retrieved articles reporting favorable functional outcome(modified Rankin Scale [mRS] 0-1) and functional independence (mRS 0-2), 90-day mortality and symptomatic intracranial hemorrhage (sICH). We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA) to maintain methodological rigor and transparency in our meta-analysis. RESULTS We conducted a meta-analysis of 22 studies (4,985 patients) to reveal no significant differences in favorable functional outcomes and independence across all groups. However, in patients treated between 2015 and 2023, EVT exhibited a higher risk of 90-day mortality (Odds Ratio [OR] = 1.84, 95% Confidence Interval [CI] [1.10, 3.07], p = 0.02) and sICH (OR = 3.36, 95% CI [1.96, 6.66], p < 0.01). EVT correlated with elevated sICH in the anterior circulation (OR=2.94, 95%CI [1.82, 4.74], p<0.01) regardless of the proximal (OR=2.20, 95%CI [1.04, 4.69], p=0.04) or distal (OR=3.44, 95%CI [1.43, 8.32], p<0.01) location of the occlusion. EVT correlated with elevated sICH rates in patients treated within 6 hours of symptom onset or those with NHISS≤5. CONCLUSION In patients treated between 2015 and 2023, EVT and MM did not differ in efficacy in acute LVO mild stroke; MM associated with better safety outcomes. Rigorous randomized controlled trials are warranted.

Abstract
BACKGROUND The effectiveness of endovascular treatment (EVT) in patients with mild stroke (National Institutes of Health Stroke Scale score ≤5) and acute anterior circulation large vessel occlusion (AACLVO) remains unknown. OBJECTIVE To conduct a meta-analysis to compare the efficacy and safety of EVT in patients with mild stroke and AACLVO. METHODS EMBASE, Cochrane Library, PubMed, and Clinicaltrials.gov databases were searched until October 2022. Both retrospective and prospective studies which compared the clinical outcomes between EVT and medical treatment were included. ORs and 95% confidence intervals (CIs) for excellent and favorable functional outcomes, symptomatic intracranial hemorrhage (ICH), and mortality were pooled using a random-effects model. A propensity score (PS)-based methods adjusted analysis was also performed. RESULTS 4335 patients from 14 studies were included. In patients with mild stroke and AACLVO, EVT presented no marked differences in excellent and favorable functional outcomes and mortality compared with medical treatment. A higher risk of symptomatic ICH (OR=2.79; 95% CI 1.49 to 5.24; P=0.001) was observed with EVT. Subgroup analysis revealed that EVT had potential benefit for proximal occlusions with excellent functional outcomes (OR=1.68; 95% CI 1.01 to 2.82; P=0.05). Similar results were observed when PS-based methods adjusted analysis was used. CONCLUSION EVT did not significantly benefit clinical functional outcomes in comparison with medical treatment in patients with mild stroke and AACLVO. However, it may improve functional outcomes when treating patients with proximal occlusion, despite being associated with an increased risk of symptomatic ICH. Stronger evidence from ongoing randomized controlled trials is required.

The efficacy and safety of general anesthesia vs. conscious sedation for endovascular treatment in patients with acute ischemic stroke: a systematic review and meta-analysis. Front Neurol 2023; 14:1291730.

Abstract
Background Endovascular thrombectomy (EVT) is an important treatment for patients with acute ischemic stroke (AIS). A number of studies have suggested that anesthesia type (conscious sedation vs. general anesthesia) during intra-arterial treatment for acute ischemic stroke has implications for patient outcomes. Methods PubMed, EMBASE, Cochrane Library and clinicaltrials.gov were searched for randomized controlled trials (RCTs) that were performed to evaluate general anesthesia (GA) and conscious sedation (CS) up to May 30, 2023. Review Manager 5.3 software was used to assess the data. The risk ratio (RR) and mean difference (MD) were analyzed and calculated with a fixed effect model. Results We pooled 930 patients from seven RCTs. We conducted a meta-analysis comparing the outcomes of GA and CS in the included trials. The rate of functional independence in the GA group was higher than that in the CS group (RR: 1.17, 95% CI: 1.00-1.35; P = 0.04; I2 = 16%). The GA group had a higher successful recanalization rate than the CS group (RR: 1.15, 95% CI: 1.08-1.22; P < 0.0001; I2 = 26%). The GA group had a higher pneumonia rate than the CS group (RR: 1.69, 95% CI: 1.22-2.34; P = 0.002; I2 = 26%). In addition, there was no significant difference between GA and CS with respect to the National Institutes of Health Stroke Scale (NIHSS) score at 24 h (P = 0.62), Modified Rankin Scale (mRS) score at 90 days (P = 0.25), intracerebral hemorrhage (P = 0.54), and mortality at 3 months (P = 0.61). Conclusion GA demonstrated superiority over CS in achieving successful recanalization and functional independence at 3 months when performing EVT in AIS patients. However, it was also associated with a higher risk of pneumonia. Further studies, particularly those with long-term follow-ups, are necessary to identify precise strategies for selecting the appropriate anesthetic modality in EVT patients.

Abstract
BACKGROUND Endovascular treatment (EVT) for acute ischemic stroke (AIS) patients presenting with National Institutes of Health Stroke Scale score of 0 to 5 is common in clinical practice but has not yet been proven safe and effective. Our objective is to assess whether EVT on top of best medical treatment (BMT) in AIS patients with large-vessel occlusion of the anterior circulation presenting with mild symptoms is beneficial compared with BMT. METHODS We searched MEDLINE, SCOPUS, and reference lists of retrieved articles published until December 28, 2022. A systematic literature search was conducted to identify clinical trials or observational cohort studies evaluating patients with AIS due to anterior circulation large-vessel occlusion and admission National Institutes of Health Stroke Scale score ≤5 treated with EVT versus BMT alone. The primary outcome was excellent functional outcome (modified Rankin Scale score 0-1) at 3 months. The protocol had been registered before data collection (PROSPERO). RESULTS Eleven observational eligible studies were included in the meta-analysis, comprising a total of 2019 AIS patients with National Institutes of Health Stroke Scale score ≤5 treated with EVT versus 3171 patients treated with BMT. EVT was not associated with excellent functional outcome (risk ratio, 1.10 [95% CI, 0.93-1.31]). When stratified for different study design (per-protocol versus intention-to-treat), there were no significant subgroup differences. EVT was not associated with good functional outcome (modified Rankin Scale score 0-2; risk ratio, 1.01 [95% CI, 0.89-1.16]) or reduced disability at 3 months (common odds ratio, 0.92 [95% CI, 0.60-1.41]). Symptomatic intracranial hemorrhage was more common in the patients receiving EVT (risk ratio, 3.53 [95% CI, 2.35-5.31]). No correlation was found between EVT and mortality at 3 months (risk ratio, 1.34 [95% CI, 0.83-2.18]). The same overall associations were confirmed in the sensitivity analysis of studies that performed propensity score matching. CONCLUSIONS EVT appears equivalent to BMT for patients with anterior circulation large-vessel occlusion AIS with low baseline National Institutes of Health Stroke Scale, despite the increased risk for symptomatic intracranial hemorrhage.

Abstract
Mechanical thrombectomy is a ground breaking treatment for acute ischaemic stroke caused by occlusion of a large vessel. Its efficacy over intravenous thrombolysis has been proven in multiple trials with a lower number needed to treat than percutaneous coronary intervention for acute myocardial infarction. However, access to this key treatment modality remains limited with a considerable postcode lottery across the UK and many parts of the world. The evidence base for mechanical thrombectomy dates back to 2015. Since then, there have been important advances in establishing and widening the criteria for treatment. This narrative review aims to summarise the current evidence base and latest advances for physicians and academics with an interest in recanalisation treatments for acute ischaemic stroke.

Abstract
Patients with acute ischemic stroke (AIS) presenting mild symptoms with a low National Institutes of Health Stroke Scale (NIHSS) score ≤8 and also found to have an intracranial large vessel occlusion (LVO) undergo endovascular thrombolysis (ET) or medical management alone. The current study aimed to evaluate the safety and effectiveness of medical management vs. ET therapy among patients with mild AIS symptoms (NIHSS score ≤8) accompanied by LVO. The present meta-analysis included articles involving mild AIS, LVO, thrombectomy/ET and medical management alone published in full-text form (from 1980 to 2022). Collected variables included: First author name, covered study period, publication year, the total number of patients and age, number of males, presence of diabetes mellitus, hypertension, atrial fibrillation, prior ischemic stroke, location, NIHSS of admission, modified Rankin scale, bleeding, morbidity and mortality. After the initial search and applying all exclusion and inclusion criteria, eight articles were left in the final article pool. The total number of patients who underwent ET was 569, compared with 1097 with medical management for LVO strokes with minimal symptoms. The findings of the present meta-analysis study point out that ET management may be associated with a high risk of bleeding and mortality in patients with LVO presenting with mild symptoms (NIHSS score ≤8).

Abstract
PURPOSE There is little data on the safety and efficacy of endovascular treatment (EVT) in comparison with intravenous thrombolysis (IVT) in acute ischemic stroke due to isolated posterior cerebral artery occlusion (IPCAO). We aimed to investigate the functional and safety outcomes of stroke patients with acute IPCAO treated with EVT (with or without prior bridging IVT) compared to IVT alone. METHODS We did a multicenter retrospective analysis of data from the Swiss Stroke Registry. The primary endpoint was overall functional outcome at 3 months in patients undergoing EVT alone or as part of bridging, compared with IVT alone (shift analysis). Safety endpoints were mortality and symptomatic intracranial hemorrhage. EVT and IVT patients were matched 1:1 using propensity scores. Differences in outcomes were examined using ordinal and logistic regression models. FINDINGS Out of 17,968 patients, 268 met the inclusion criteria and 136 were matched by propensity scores. The overall functional outcome at 3 months was comparable between the two groups (EVT vs IVT as reference category: OR = 1.42 for higher mRS, 95% CI = 0.78-2.57, p = 0.254). The proportion of patients independent at 3 months was 63.2% in EVT and 72.1% in IVT (OR = 0.67, 95% CI = 0.32-1.37, p = 0.272). Symptomatic intracranial hemorrhages were overall rare and present only in the IVT group (IVT = 5.9% vs EVT = 0%). Mortality at 3 months was also similar between the two groups (IVT = 0% vs EVT = 1.5%). CONCLUSION In this multicenter nested analysis, EVT and IVT in patients with acute ischemic stroke due to IPCAO were associated with similar overall good functional outcome and safety. Randomized studies are warranted.

Neurology 2023; 100:e627-e638. [PMID: 36307224 PMCID: PMC9946183 DOI: 10.1212/wnl.0000000000201498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Accepted: 09/15/2022] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND AND OBJECTIVES The best management of patients with mild stroke and large vessel occlusion (LVO) remains unclear. This study aimed to identify perfusion imaging predictors of poor functional outcome in such patients. METHODS This cohort study retrospectively selected patients enrolled in the International Stroke Perfusion Imaging Registry between August 2011 and April 2022. The registry enrolled patients with acute ischemic stroke and with baseline CT perfusion scanned within 24 hours of stroke onset. This study identified patients with mild symptoms, defined by an NIH Stroke Scale score of ≤5. Patients with LVO of anterior circulation were selected. This study further selected patients who received medical management and excluded patients who received endovascular treatment. The primary outcome was poor functional outcome defined as a modified Rankin Scale of 3-6 at 3 months. Perfusion lesion was defined by delay time > 3 seconds on CTP. Regression analyses were used to identify clinical and imaging variables that predicted poor functional outcome. RESULTS A total of 139 patients with mild stroke were included, of whom 27 (19%) had poor functional outcome. Patients with poor outcome, compared with those with good outcome, had much larger perfusion lesion volume (median 80 mL vs 41 mL, p < 0.001). Perfusion lesion was a significant predictor of poor outcome in either univariable regression (crude OR = 1.02, 95% CI = [1.01-1.03]) or multivariable regression model (adjusted OR = 1.01, 95% CI = [1.01-1.02]), adjusting for occlusion site, good collaterals, baseline stroke severity, age, IV thrombolysis (IVT), and onset to scan time. A perfusion lesion of 65 mL was the optimal cutpoint to identify poor functional outcome (sensitivity = 59%, specificity = 77%). Patients with perfusion lesion ≥65 mL, compared with patients with perfusion lesion <65 mL, showed a much higher rate of poor functional outcome (38% vs 11%, p < 0.001). Of the 139 patients in this study, 95 received IVT. Patients treated with or without IVT did not influence their outcomes (crude OR = 0.74, 95% CI = [0.31-1.78]). DISCUSSION A perfusion lesion of ≥65 mL predicted poor functional outcome in mild stroke patients with LVO.

Brain Sci 2023; 13:brainsci13020214. [PMID: 36831757 PMCID: PMC9953866 DOI: 10.3390/brainsci13020214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 01/23/2023] [Accepted: 01/25/2023] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND AND PURPOSE Minor acute ischemic stroke (AIS) patients-defined by an NIHSS score < 6-presenting with proximal middle cerebral artery large vessel occlusions (MCA-LVO) is a subgroup for which treatment is still debated. Although these patients present with minor symptoms initially, studies have shown that several patients afflicted with MCA-LVO in this subgroup experience cognitive and functional decline. Although mechanical thrombectomy (MT) is the standard of care for patients with an NIHSS score of 6 or higher, treatment in the minor stroke subgroup is still being explored. The purpose of this preliminary study is to report our center's experience in evaluating the potential benefit of mechanical thrombectomy (MT) in minor stroke patients when compared to medical management (MM). METHODS We performed a retrospective study with two comprehensive stroke centers within our hospital enterprise of consecutive patients presenting with minor AIS secondary to MCA-LVO (defined as M1 or proximal M2 segments of MCA). We subsequently evaluated patients who received MT versus those who received MM. RESULTS Between January 2017 and July 2021, we identified 46 AIS patients (11 treated with MT and 35 treated with MM) who presented with an NIHSS score < 6 secondary to MCA-LVO (47.8% 22/46 female, mean age 62.3 years, range 49-75 years). MT was associated with a significantly lower mRS at 90 days (median: 1.0 [IQR 0.0-2.0] versus 3.0 [IQR 1.0-4.0], p = <0.001), a favorable NIHSS shift (-4.0 [IQR -10.0--2.0] versus 0.0 [IQR -2.0-1.0], p = 0.002), favorable NIHSS shift dichotomization (5/11, 45.5% versus 3/35, 8.6%, p = 0.003) and favorable mRS dichotomization (7/11, 63.6% versus 14/35, 40.0%, p = 0.024). CONCLUSIONS In our center's preliminary experience, for AIS patients presenting with an NIHSS score < 6 secondary to MCA-LVO, MT may be associated with improved clinical outcomes when compared to MM only.

Abstract
BACKGROUND To evaluate the cost-effectiveness of endovascular thrombectomy (EVT) to treat large vessel occlusion (LVO) in patients with acute, minor stroke (National Institute of Health Stroke Scale (NIHSS) <6) and impact of occlusion site. METHODS A Markov decision-analytic model was constructed accounting for both costs and outcomes from a societal perspective. Two different management strategies were evaluated: EVT and medical management. Base case analysis was done for three different sites of occlusion: proximal M1, distal M1 and M2 occlusions. One-way, two-way and probabilistic sensitivity analyses were performed. RESULTS Base-case calculation showed EVT to be the dominant strategy in 65-year-old patients with proximal M1 occlusion and NIHSS <6, with lower cost (US$37 229 per patient) and higher effectiveness (1.47 quality-adjusted life years (QALYs)), equivalent to 537 days in perfect health or 603 days in modified Rankin score (mRS) 0-2 health state. EVT is the cost-effective strategy in 92.7% of iterations for patients with proximal M1 occlusion using a willingness-to-pay threshold of US$100 000/QALY. EVT was cost-effective if it had better outcomes in 2%-3% more patients than intravenous thrombolysis (IVT) in absolute numbers (base case difference -16%). EVT was cost-effective when the proportion of M2 occlusions was less than 37.1%. CONCLUSIONS EVT is cost-effective in patients with minor stroke and LVO in the long term (lifetime horizon), considering the poor outcomes and significant disability associated with non-reperfusion. Our study emphasizes the need for caution in interpreting previous observational studies which concluded similar results in EVT versus medical management in patients with minor stroke due to a high proportion of patients with M2 occlusions in the two strategies.

Abstract
Background It remains uncertain whether patients with minor acute ischemic stroke with large vessel occlusion benefit from endovascular treatment (EVT). We aim to evaluate the outcomes of EVT in minor acute ischemic stroke with anterior circulation large vessel occlusion. Methods and Results Based on a nationwide prospective stroke registry, patients with minor acute ischemic stroke with anterior circulation large vessel occlusion within 24 hours of onset were divided into groups receiving standard medical treatment plus EVT or standard medical treatment alone. Primary outcome was excellent functional outcome defined as modified Rankin Scale score 0 to 1 at 90 days. In addition, a multivariable logistic regression model was used to analyze the effect of EVT guided by perfusion imaging. A total of 572 patients with median age 68 years (interquartile range=60-77) and median National Institutes of Health Stroke score 3 (interquartile range =2-4) were identified and 123 patients were treated with standard medical treatment plus EVT. EVT was not associated with excellent functional outcome (unadjusted odds ratio [OR], 0.771 [95% CI, 0.516-1.151]; adjusted OR, 0.793 [95% CI, 0.515-1.219]; P=0.290). However, therapy selection guided by perfusion imaging was a modifier of EVT effect on outcomes, as EVT was significantly associated with excellent functional outcome (60.0% versus 50.8%, unadjusted OR, 1.451 [95% CI, 0.643-3.272]; adjusted OR, 2.849 [95% CI, 1.006-8.067]; P=0.049) but not with symptomatic intracerebral hemorrhage in the imaging-guided group. Conclusions Although functional outcomes in minor acute ischemic stroke caused by anterior circulation large vessel occlusion were not improved from the routine use of EVT, our results suggested that EVT guided by perfusion imaging could be beneficial for those patients.

Abstract
OBJECTIVE Authors of this study aimed to investigate the efficacy and safety of endovascular treatment (EVT) versus standard medical treatment (SMT) alone in patients with acute basilar artery occlusion (BAO) and moderate deficit (National Institutes of Health Stroke Scale [NIHSS] score 10-19). METHODS Patients with moderate deficit caused by acute BAO in the period from January 2014 to May 2019 were included in the study. The patients were divided into groups based on treatment: EVT plus SMT group or SMT-alone group. The primary outcome was favorable functional outcome (modified Rankin Scale score 0-3) at 90 days, and safety outcomes were symptomatic intracerebral hemorrhage (sICH) and mortality at 90 days. RESULTS A total of 173 patients had moderate deficits, 128 of whom had been treated with EVT and 45 with SMT alone. EVT was associated with a significant higher proportion of 90-day favorable outcomes compared with SMT (adjusted odds ratio [aOR] 4.09, 95% CI 1.39-12.04, p = 0.011). Younger age (aOR 0.96, 95% CI 0.92-0.99, p = 0.017), absence of diabetes mellitus (aOR 0.35, 95% CI 0.12-0.99, p = 0.048), higher baseline posterior circulation Acute Stroke Prognosis Early Computed Tomography Score (pc-ASPECTS; aOR 1.48, 95% CI 1.07-2.05, p = 0.018), and modified Thrombolysis in Cerebral Infarction (mTICI) score of 2b-3 (aOR 15.15, 95% CI 3.07-74.72, p = 0.001) were independent factors for a favorable outcome in the EVT group. Rates of mortality and sICH were comparable in the EVT and SMT groups. CONCLUSIONS EVT leads to improved outcomes compared to those with SMT alone. Younger age, absence of diabetes mellitus, higher baseline pc-ASPECTSs, and mTICI score of 2b-3 were associated with better functional outcome in the EVT group.

[PMID: 36183595 DOI: 10.1016/j.thromres.2022.09.020] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 09/19/2022] [Accepted: 09/22/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Whether direct endovascular thrombectomy (EVT) is non-inferior to bridging therapy (intravenous thrombolysis [IVT] followed by EVT) in minor acute ischemic stroke due to large vessel occlusions (AIS-LVO) is not clear. Therefore, this study aimed to assess whether direct EVT is non-inferior to bridging therapy in minor AIS-LVO. METHODS 903 patients with acute ischemic stroke due to large vessel occlusion and National Institutes of Health Stroke Scale (NIHSS) score <6 receiving EVT treatment were enrolled at Bigdata Observatory Platform for Stroke of China in China from January 1, 2019, to December 31, 2020, with final follow-up on March 31, 2021. The primary efficacy endpoint was a favorable outcome defined as a modified Rankin Scale score of 0 to 2 at three months. In addition, there were three prespecified secondary efficacy endpoints, including symptomatic intracerebral hemorrhage (ICH), in-hospital mortality, and mortality by month 3. RESULTS A total of 662 patients treated with direct EVT (age 65.9 ± 10.5 years, 71.5 % male, NIHSS score 2.4 [standard deviation {SD}. 1.8]) were compared to 241 bridging-treated patients (age 65.7 ± 10.8, 75.9 % female, NIHSS score 2.5 [1.8]). The rate of symptomatic ICH in the EVT group was lower than in the bridging group (4.2 % vs. 8.3 %; P = 0.02). The in-hospital mortality was not different between the two groups (EVT vs. bridging group: adjusted hazard ratio {HR}, 0.9 [95 % confidence interval {CI}, 0.5 to 1.9]; P = 0.93). There was no significant difference in 3-month poor functional outcome rate (EVT vs. bridging group: 17.1 % vs. 16.2 % [absolute difference, 0.9 % {95 % CI, -0.8 % to 2.4 %}, P = 0.75; adjusted hazard ratio {HR}, 1.0 {95 % CI, 0.6 to 1.7}, P = 0.83]) and mortality rate (13.0 % vs. 11.2 % [absolute difference, 1.5 % {95 % CI, -3.9 % to 6.8 %}, P = 0.47; adjusted HR, 1.1 {95 % CI, 0.8 to 1.9}, P = 0.55]) between those two groups. CONCLUSION Among patients with minor AIS-LVO, direct EVT, compared with bridging therapy, met the prespecified statistical threshold for noninferiority for the 3-month prognosis.

[PMID: 36007262 DOI: 10.1016/j.jstrokecerebrovasdis.2022.106684] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 06/13/2022] [Accepted: 07/24/2022] [Indexed: 11/30/2022] Open
Abstract
PURPOSE The purpose of this study was to evaluate the impact of reperfusion in patients with large vessel occlusion (LVO) of the anterior circulation and National Institutes of Health Stroke Scale (NIHSS)< 6. METHODS It was a retrospective cohort study. The reperfusion grade was determined using the modified thrombolysis in cerebral infarction (TICI) score. The modified Rankin Score (mRS) ≤1 were defined as excellent and (mRS) ≤2 as favorable outcome at 3-month. Meanwhile, the all-cause mortality, intracerebral hemorrhage, and complications were recorded. Multivariate logistic regression analyses were performed to evaluate outcomes. RESULTS Seventy-six patients (86.4%) achieved reperfusion (TICI2B/3). Excellent outcome was achieved in 62 (70.5%) and favorable outcome in 69 (78.4%). All-cause death occurred in 2 (2.3%). The rate of excellent outcome in patients with TICI0,1,2A was 41.7%, with TICI2B 69.2%, and with TICI3 78.0% (p < 0.05). In a multivariate logistic regression analysis related to excellent outcome, the OR(95% CI) was 5.68(1.35,23.95) for TICI3; the test for linear trend by entering categorical variables as continuous variables in the adjusted model (p for trend=0.02<0.05), defining TICI0,1,2A as reference. Subgroup analyses showed without intravenous thrombolysis (IVT) (OR, 14.29; 95% CI, 1.76-116.37) and with middle cerebral artery (MCA) occlusion (OR, 7.97; 95% CI,1.26-50.32), the excellent outcome further improved with TICI3. Findings were similar in favorable outcome. CONCLUSIONS Our results indicated that successful reperfusion was intensely connected with better functional outcomes for patients with LVO presenting with NIHSS<6 in the anterior circulation, especially MCA occlusion and pretreatment without IVT.

Abstract
Background and Purpose Knowledge about different etiologies of non-traumatic intracerebral hemorrhage (ICH) and their outcomes is scarce.Methods We assessed prevalence of pre-specified ICH etiologies and their association with outcomes in consecutive ICH patients enrolled in the prospective Swiss Stroke Registry (2014 to 2019). Results We included 2,650 patients (mean±standard deviation age 72±14 years, 46.5% female, median National Institutes of Health Stroke Scale 8 [interquartile range, 3 to 15]). Etiology was as follows: hypertension, 1,238 (46.7%); unknown, 566 (21.4%); antithrombotic therapy, 227 (8.6%); cerebral amyloid angiopathy (CAA), 217 (8.2%); macrovascular cause, 128 (4.8%); other determined etiology, 274 patients (10.3%). At 3 months, 880 patients (33.2%) were functionally independent and 664 had died (25.1%). ICH due to hypertension had a higher odds of functional independence (adjusted odds ratio [aOR], 1.33; 95% confidence interval [CI], 1.00 to 1.77; <i>P</i>=0.05) and lower mortality (aOR, 0.64; 95% CI, 0.47 to 0.86; <i>P</i>=0.003). ICH due to antithrombotic therapy had higher mortality (aOR, 1.62; 95% CI, 1.01 to 2.61; <i>P</i>=0.045). Within 3 months, 4.2% of patients had cerebrovascular events. The rate of ischemic stroke was higher than that of recurrent ICH in all etiologies but CAA and unknown etiology. CAA had high odds of recurrent ICH (aOR, 3.38; 95% CI, 1.48 to 7.69; <i>P</i>=0.004) while the odds was lower in ICH due to hypertension (aOR, 0.42; 95% CI, 0.19 to 0.93; <i>P</i>=0.031).Conclusions Although hypertension is the leading etiology of ICH, other etiologies are frequent. One-third of ICH patients are functionally independent at 3 months. Except for patients with presumed CAA, the risk of ischemic stroke within 3 months of ICH was higher than the risk of recurrent hemorrhage.

Abstract
Objective To examine rates of intravenous thrombolysis (IVT), mechanical thrombectomy (MT), door‐to‐needle (DTN) time, door‐to‐puncture (DTP) time, and functional outcome between patients with admission magnetic resonance imaging (MRI) versus computed tomography (CT). Methods An observational cohort study of consecutive patients using a target trial design within the nationwide Swiss‐Stroke‐Registry from January 2014 to August 2020 was carried out. Exclusion criteria included MRI contraindications, transferred patients, and unstable or frail patients. Multilevel mixed‐effects logistic regression with multiple imputation was used to calculate adjusted odds ratios with 95% confidence intervals for IVT, MT, DTN, DTP, and good functional outcome (mRS 0–2) at 90 days. Results Of the 11,049 patients included (mean [SD] age, 71 [15] years; 4,811 [44%] women; 69% ischemic stroke, 16% transient ischemic attack, 8% stroke mimics, 6% intracranial hemorrhage), 3,741 (34%) received MRI and 7,308 (66%) CT. Patients undergoing MRI had lower National Institutes of Health Stroke Scale (median [interquartile range] 2 [0–6] vs 4 [1–11]), and presented later after symptom onset (150 vs 123 min, p < 0.001). Admission MRI was associated with: lower adjusted odds of IVT (aOR 0.83, 0.73–0.96), but not with MT (aOR 1.11, 0.93–1.34); longer adjusted DTN (+22 min [13–30]), but not with longer DTP times; and higher adjusted odds of favorable outcome (aOR 1.54, 1.30–1.81). Interpretation We found an association of MRI with lower rates of IVT and a significant delay in DTN, but not in DTP and rates of MT. Given the delays in workflow metrics, prospective trials are required to show that tissue‐based benefits of baseline MRI compensate for the temporal benefits of CT. ANN NEUROL 2022;92:184–194

Effect of admission time on provision of acute stroke treatment at stroke units and stroke centers—An analysis of the Swiss Stroke Registry. Eur Stroke J 2022; 7:117-125.

Abstract
Introduction: Rapid treatment of acute ischemic stroke (AIS) depends on sufficient staffing which differs between Stroke Centers and Stroke Units in Switzerland. We studied the effect of admission time on performance measures of AIS treatment and related temporal trends over time. Patients and methods: We compared treatment rates, door-to-image-time, door-to-needle-time, and door-to-groin-puncture-time in stroke patients admitted during office hours (Monday–Friday 8:00–17:59) and non-office hours at all certified Stroke Centers and Stroke Units in Switzerland, as well as secular trends thereof between 2014 and 2019, using data from the Swiss Stroke Registry. Secondary outcomes were modified Rankin Scale and mortality at 3 months. Results: Data were eligible for analysis in 31,788 (90.2%) of 35,261 patients. Treatment rates for IVT/EVT were higher during non-office hours compared with office hours in Stroke Centers (40.8 vs 36.5%) and Stroke Units (21.8 vs 18.5%). Door-to-image-time and door-to-needle-time increased significantly during non-office hours. Median (IQR) door-to-groin-puncture-time at Stroke Centers was longer during non-office hours compared to office hours (84 (59–116) vs 95 (66–130) minutes). Admission during non-office hours was independently associated with worse functional outcome (1.11 [95%CI: 1.04–1.18]) and increased mortality (1.13 [95%CI: 1.01–1.27]). From 2014 to 2019, median door-to-groin-puncture-time improved and the treatment rate for wake-up strokes increased. Discussion and Conclusion: Despite differences in staffing, patient admission during non-office hours delayed IVT to a similar, modest degree at Stroke Centers and Stroke Units. A larger delay of EVT was observed during non-office hours, but Stroke Centers sped up delivery of EVT over time. Patients admitted during non-office hours had worse functional outcomes, which was not explained by treatment delays.

Abstract
BACKGROUND The functional prognosis of mechanical thrombectomy (MT) for mild acute ischemic stroke (AIS) with large-vessel occlusion (LVO) is controversial. To explore a more precise estimation, a meta-analysis was conducted. METHODS The relevant studies were identified by searching PubMed, Embase, Web of Science, and Cochrane Collaboration Database until October 2021. The pooled analysis, subgroup analysis, sensitivity analysis, and publication bias examination were all conducted. The meta-analysis was performed by using Stata 12.0. RESULTS Eleven studies were included with a total of 1,929 subjects, including 794 patients receiving MT and 1,135 patients receiving medical management. The pooled analysis showed that MT might be not associated with functional prognosis among mild AIS with LVO (excellent functional prognosis: risk ratio (RR) = 1.07, 95% confidence interval (CI) = 0.94-1.21, p = 0.294; favorable functional prognosis: RR = 1.01, 95% CI = 0.96-1.06, p = 0.823). The statistical stability and reliability were demonstrated by the sensitivity analysis and publication bias outcomes. CONCLUSION Our meta-analysis suggests that MT may be not associated with functional prognosis of mild AIS with LVO.

Abstract
BACKGROUND Endovascular treatment in large artery occlusion stroke reduces disability. However, the impact of anesthesia type on clinical outcomes remains uncertain. METHODS We compared consecutive patients in the Swiss Stroke Registry with anterior circulation stroke receiving endovascular treatment with or without general anesthesia (GA). The primary outcome was disability on the modified Rankin Scale after 3 months, analyzed with ordered logistic regression. Secondary outcomes included dependency or death (modified Rankin Scale score ≥3), National Institutes of Health Stroke Scale after 24 hours, symptomatic intracranial hemorrhage with ≥4 points worsening on National Institutes of Health Stroke Scale within 7 days, and mortality. Coarsened exact matching and propensity score matching were performed to adjust for indication bias. RESULTS One thousand two hundred eighty-four patients (GA: n=851, non-GA: n=433) from 8 Stroke Centers were included. Patients treated with GA had higher modified Rankin Scale scores after 3 months than patients treated without GA, in the unmatched (odds ratio [OR], 1.75 [1.42-2.16]; P<0.001), the coarsened exact matching (n=332-524, using multiple imputations of missing values; OR, 1.60 [1.08-2.36]; P=0.020), and the propensity score matching analysis (n=568; OR, 1.61 [1.20-2.15]; P=0.001). In the coarsened exact matching analysis, there were no significant differences in National Institutes of Health Stroke Scale after 1 day (estimated coefficient 2.61 [0.59-4.64]), symptomatic intracranial hemorrhage (OR, 1.06 [0.30-3.75]), dependency or death (OR, 1.42 [0.91-2.23]), or mortality (OR, 1.65 [0.94-2.89]). In the propensity score matching analysis, National Institutes of Health Stroke Scale after 24 hours (estimated coefficient, 3.40 [1.76-5.04]), dependency or death (OR, 1.49 [1.07-2.07]), and mortality (OR, 1.65 [1.11-2.45]) were higher in the GA group, whereas symptomatic intracranial hemorrhage did not differ significantly (OR, 1.77 [0.73-4.29]). CONCLUSIONS This large study showed worse functional outcome after endovascular treatment of anterior circulation stroke with GA than without GA in a real-world setting. This finding appears to be independent of known differences in patient characteristics between groups.

Abstract
CONTEXT Correction of hyponatremia might represent an additional treatment for improving stroke patients' clinical outcomes. OBJECTIVE Admission hyponatremia is associated with worse clinical outcome in stroke patients, but whether normalization of hyponatremia improves outcome is unknown. We investigated whether normalization of hyponatremia affects patients' disability, mortality, and stroke recurrence within 3 months; length of hospitalization; and discharge destination. DESIGN This was a registry-based analysis of data collected between January 2016 and December 2018. We linked data from Swiss Stroke Registry (SSR) with electronic patients' records for extracting sodium values. SETTING We analyzed data of hospitalized patients treated at University Hospital of Basel. PATIENTS Stroke patients whose data and informed consent were available. MAIN OUTCOME MEASURE Modified Rankin Scale (mRS) score at 3 months. The tested hypothesis was formulated after SSR data collection but before linkage with electronic patients' records. RESULTS Of 1995 patients, 144 (7.2%) had hyponatremia on admission; 102 (70.8%) reached normonatremia, and 42 (29.2%) remained hyponatremic at discharge. An increase of initial sodium was associated with better functional outcome at 3 months (odds ratio [OR] 0.94; 95% CI, 0.90-0.99, for a shift to higher mRS per 1 mmol/L sodium increase). Compared with normonatremic patients, patients who remained hyponatremic at discharge had a worse functional outcome at 3 months (odds ratio 2.46; 95% CI, 1.20-5.03, for a shift to higher mRS). No effect was found on mortality, recurrence, or length of hospitalization. CONCLUSIONS In hospitalized acute stroke patients, persistent hyponatremia is associated with worse functional outcome. Whether active correction of hyponatremia improves outcome remains to be determined in prospective studies.

Mechanical Thrombectomy in Patients Presenting with NIHSS Score <6: A Safety and Efficacy Analysis. J Stroke Cerebrovasc Dis 2022; 31:106282. [PMID: 34998043 DOI: 10.1016/j.jstrokecerebrovasdis.2021.106282] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 10/24/2021] [Accepted: 12/19/2021] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Groundbreaking trials have shown the tremendous efficacy of mechanical thrombectomy for large vessel occlusions. Currently, mechanical thrombectomy is limited to patients with NIHSS scores ≥6. We investigated the feasibility and safety of MT in patients presenting with NIHSS scores <6. MATERIALS AND METHODS A retrospective review of patient who presented with acute ischemic stroke due to large vessel occlusion with an NIHSS score <6 between 2015 - 2021. The patients were then divided into two groups: those who received mechanical thrombectomy and those who did not. RESULTS Among 83 patients, 41 received a mechanical thrombectomy while 42 received medical treatment only. The mean age in the mechanical thrombectomy group was 66 years versus 60 years in the medical group (p = 0.06). Risk factors for stroke did not differ significantly between both groups. 14 patients (34.1%) in the mechanical thrombectomy group and 20 (47.6%) in the medical group received tissue plasminogen activator. No significant difference in clinical improvement (NIHSS) at discharge (p=0.85) or the mRS score at 90 days (p = 0.15) was noted. Mechanical thrombectomy was associated with smaller infarct size (p=0.04) and decreased mortality (p=0.03). CONCLUSIONS Mechanical thrombectomy is safe and effective for patients who present with large vessel occlusions and low initial NIHSS scores. Therefore, the decision to offer the patient mechanical thrombectomy or not should not be decided by NIHSS score alone. Rather, the decision should be multifactorial with the aim of maximizing the patients' outcomes.

Abstract
Background and purpose In Switzerland, the COVID‐19 incidence during the first pandemic wave was high. Our aim was to assess the association of the outbreak with acute stroke care in Switzerland in spring 2020. Methods This was a retrospective analysis based on the Swiss Stroke Registry, which includes consecutive patients with acute cerebrovascular events admitted to Swiss Stroke Units and Stroke Centers. A linear model was fitted to the weekly admission from 2018 and 2019 and was used to quantify deviations from the expected weekly admissions from 13 March to 26 April 2020 (the “lockdown period”). Characteristics and 3‐month outcome of patients admitted during the lockdown period were compared with patients admitted during the same calendar period of 2018 and 2019. Results In all, 28,310 patients admitted between 1 January 2018 and 26 April 2020 were included. Of these, 4491 (15.9%) were admitted in the periods March 13–April 26 of the years 2018–2020. During the lockdown in 2020, the weekly admissions dropped by up to 22% compared to rates expected from 2018 and 2019. During three consecutive weeks, weekly admissions fell below the 5% quantile (likelihood 0.38%). The proportion of intracerebral hemorrhage amongst all registered admissions increased from 7.1% to 9.3% (p = 0.006), and numerically less severe strokes were observed (median National Institutes of Health Stroke Scale from 3 to 2, p = 0.07). Conclusions Admissions and clinical severity of acute cerebrovascular events decreased substantially during the lockdown in Switzerland. Delivery and quality of acute stroke care were maintained.

Abstract
Patients with acute ischemic stroke may present with minor neurologic deficits. Acute treatment decisions depend on the disability imposed by the symptoms along with radiographic features. The presence of disabling neurologic deficits warrants intravenous thrombolysis, but the indications for endovascular therapy are less defined. The degree of disability, presence of a large vessel occlusion with perfusion mismatch, and collateral circulation status may all be factors in selecting patients for endovascular treatment. Identification of patients who are at risk for neurologic deterioration is critical to preventing poor outcomes in this patient population.

Abstract
Mechanical thrombectomy (MT) has become the standard procedure in the treatment of patients with acute ischemic stroke (AIS) due to occlusion of a large proximal cerebral artery of the anterior circulation. Nevertheless, according to the current guidelines large patient collectives are still excluded from this highly effective treatment method. Therefore, this article gives an overview of possible extensions of the indications for treatment with MT. For example, patients in the extended time window with distal occlusions, with large infarct cores and also for very old (90+ years) or young (0-17 years) patients. Furthermore, we discuss recent developments in the interventional treatment of stroke, such as new triage concepts or the question whether an additional intravenous thrombolysis is necessary in patients with MT. We conclude with our own estimations for the discussed indications for treatment based on our clinical experience and the current literature.

Abstract
Background Mild stroke accounts for more than a half of all stroke patients, and short-term outcomes after treatment with intravenous (IV) recombinant tissue plasminogen activator (rtPA) have not been fully investigated in this group. Methods Our study investigated short-term outcomes and predictors for a favorable functional outcome at discharge in mild stroke patients with IV rtPA. 6,752 mild stroke patients in the China Stroke Center Alliance with a clinical diagnosis of acute ischemic stroke, within 4.5 hours from symptom onset, with a baseline National Institutes of Health Stroke Scale score ≤5 and received rt-PA treatment were included in this retrospective analysis. Univariable and multivariable analyses were performed to identify factors independently associated with a favorable functional outcome. Results Only 18.5% had an unfavorable functional outcome at discharge, 91.1% were discharged home, 89.9% could ambulate independently, 95.9% had a length of stay of 3 days or longer and 1.9% had sICH. A multivariable Logistic regression model identified that age >80 years [adjusted odds ratio (aOR): 1.57 (1.1–2.25)], diabetes mellitus [aOR: 1.35 (1.16–1.58)], 3–4.5 h time window [aOR: 1.43 (1.26–1.63)] and NIHSS score [3 vs. 0, aOR: 1.49 (1.05–2.11); 4 vs. 0, aOR: 2.36 (1.68–3.33); 5 vs. 0, aOR: 2.51 (1.77–3.56)] were independent risk factors for mRS >2 with hospital region, hospital level and hypertension as covariates. Conclusions Our findings suggest that tPA is safe and effective in mild stroke patients with age ≤80 within the 3 hour time window and in those without diabetes mellitus, further studies are needed to confirm the findings.

Hypersensitive C-reactive protein-albumin ratio predicts symptomatic intracranial hemorrhage after endovascular therapy in acute ischemic stroke patients. BMC Neurol 2021; 21:47. [PMID: 33522912 PMCID: PMC7849085 DOI: 10.1186/s12883-021-02066-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Accepted: 01/20/2021] [Indexed: 11/15/2022] Open
Abstract
Background Approximately 10% of patients would develop symptomatic intracranial hemorrhage (sICH) after endovascular therapy. The aim of our study was to explore the ability of hypersensitive C-reactive protein-albumin ratio (HAR) in predicting sICH after endovascular therapy. Methods From April 2016 to December 2018, 334 consecutive patients with anterior circulation infarction undergoing endovascular therapy were enrolled in our study. sICH was defined using Heidelberg bleeding classification after endovascular therapy. Multiple regression analysis was used to investigate the potential risk factors of sICH after endovascular therapy. We used receiver operating characteristic curve analysis and nomogram analysis to assess the overall discriminative ability of the HAR in predicting sICH after endovascular therapy. Results Among these 334 patients enrolled, 37 (11.1%) patients with anterior circulation infarction were identified with sICH after endovascular therapy. Univariate logistic regression analysis demonstrated that patients with higher levels of HAR may be inclined to develop sICH (odds ratio, 10.994; 95% confidence interval, 4.567–26.463; P = 0.001). This association remained significant even after adjustment for potential confounders. Also, a cutoff value of 0.526× 10− 3 for HAR was detected in predicting sICH (area under curve, 0.763). Furthermore, nomogram analysis also suggested that HAR was an indicator of sICH (c-index was 0.890, P< 0.001). Conclusions This study showed that high levels of HAR could predict sICH after endovascular therapy.

Impact of recanalisation by mechanical thrombectomy in mild acute ischemic stroke with large anterior vessel occlusion. Rev Neurol (Paris) 2021; 177:955-963. [PMID: 33487410 DOI: 10.1016/j.neurol.2020.09.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Revised: 08/06/2020] [Accepted: 09/11/2020] [Indexed: 11/23/2022]
Abstract
BACKGROUND The net clinical benefit of mechanical thrombectomy (MT) in patients presenting acute anterior circulation ischemic stroke with large-vessel occlusion (AIS-LVO) and mild neurological deficit is uncertain. AIMS To investigate efficacy and safety of MT in patients with acute AIS-LVO and mild neurological deficit by evaluating i) the influence of recanalisation on three-month outcome and ii) mortality, symptomatic intracerebral hemorrhage (sICH) and procedural complications. METHODS We included consecutive patients with acute AIS-LVO and National Institute of Stroke Scale (NIHSS) score<8, treated by MT at Lille University Hospital. Recanalisation was graded according to modified thrombolysis in cerebral infarction (mTICI) score, mTICI 2b/2c/3 being considered successful. We recorded procedural complications and classified intra-cerebral hemorrhages (ICH) and sICH according with European Cooperative Acute Stroke Study (ECASS) and ECASS2 criteria. Three-month outcome was evaluated by modified Rankin scale (mRS). Excellent and favourable outcomes were respectively defined as mRS 0-1 and 0-2 (or similar to pre-stroke). RESULTS We included 95 patients. At three months, 56 patients (59. 0%) achieved an excellent outcome and 69 (72, 6%) a favourable outcome, both being more frequent in patients with successful recanalisation than in patients without (excellent outcome 71, 1% versus 10, 5%, P<0.001 and favourable outcome 82.9% versus 31.6%, P<0.001). The difference remained unchanged after adjustment for age and pre-MT infarct volume. Similar results were observed in patients with pre-MT NIHSS ≤5. Death occurred in five patients (5.3%), procedural complications in 12 (12.6%), any ICH in 38 (40.0%), including 3 (3.2%) sICH. CONCLUSIONS Achieving successful recanalisation appears beneficial and safe in acute AIS-LVO patients with NIHSS<8 before MT.

Abstract
OBJECTIVE The aim was to evaluate, in patients with atrial fibrillation (AF) and acute ischemic stroke, the association of prior anticoagulation with vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs) with stroke severity, utilization of intravenous thrombolysis (IVT), safety of IVT, and 3-month outcomes. METHODS This was a cohort study of consecutive patients (2014-2019) on anticoagulation versus those without (controls) with regard to stroke severity, rates of IVT/mechanical thrombectomy, symptomatic intracranial hemorrhage (sICH), and favorable outcome (modified Rankin Scale score 0-2) at 3 months. RESULTS Of 8,179 patients (mean [SD] age, 79.8 [9.6] years; 49% women), 1,486 (18%) were on VKA treatment, 1,634 (20%) on DOAC treatment at stroke onset, and 5,059 controls. Stroke severity was lower in patients on DOACs (median National Institutes of Health Stroke Scale 4, [interquartile range 2-11]) compared with VKA (6, [2-14]) and controls (7, [3-15], p < 0.001; quantile regression: β -2.1, 95% confidence interval [CI] -2.6 to -1.7). The IVT rate in potentially eligible patients was significantly lower in patients on VKA (156 of 247 [63%]; adjusted odds ratio [aOR] 0.67; 95% CI 0.50-0.90) and particularly in patients on DOACs (69 of 464 [15%]; aOR 0.06; 95% CI 0.05-0.08) compared with controls (1,544 of 2,504 [74%]). sICH after IVT occurred in 3.6% (2.6-4.7%) of controls, 9 of 195 (4.6%; 1.9-9.2%; aOR 0.93; 95% CI 0.46-1.90) patients on VKA and 2 of 65 (3.1%; 0.4-10.8%, aOR 0.56; 95% CI 0.28-1.12) of those on DOACs. After adjustments for prognostic confounders, DOAC pretreatment was associated with a favorable 3-month outcome (aOR 1.24; 1.01-1.51). INTERPRETATION Prior DOAC therapy in patients with AF was associated with decreased admission stroke severity at onset and a remarkably low rate of IVT. Overall, patients on DOAC might have better functional outcome at 3 months. Further research is needed to overcome potential restrictions for IVT in patients taking DOACs. ANN NEUROL 2021;89:42-53.

[PMID: 33028674 DOI: 10.1136/neurintsurg-2020-016583] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 09/08/2020] [Accepted: 09/13/2020] [Indexed: 11/03/2022]
Abstract
While the landmark 2015 stroke trials demonstrated that endovascular therapy (EVT) was superior to medical management for the treatment of acute ischemic stroke due to large vessel occlusion, the efficacy of EVT for patients presenting with a low NIHSS score remains undetermined. We conducted a review of the EVT low National Institutes of Health Stroke Scale (NIHSS) stroke literature, identifying 24 quantitative and six qualitative publications. Details of study designs and outcome were extracted and critically discussed.All identified qualitative studies were retrospective. There was significant study design heterogeneity, with 18 unique study designs between the 24 identified quantitative manuscripts. Study investigations included low NIHSS EVT feasibility (n=6), EVT versus best medical management (BMM; n=10), EVT versus intravenous therapy (IVT, n=3), and low NIHSS score versus high NIHSS score (n=3). From single-arm EVT feasibility studies, the reported ranges of modified Thrombolysis in Cerebral Infarction and symptomatic intracranial hemorrhage were 78-97% and 0-10%, respectively. The EVT versus BMM literature had heterogeneous results with 40% reporting benefit with EVT and 60% reporting neutral findings. None of the studies comparing EVT with IVT reported a difference between the two revascularization therapies. The four identified meta-analyses had incongruent inclusion criteria and conflicting results. Two randomized trials are currently investigating EVT in patients with a low NIHSS score. Selected meta-analyses do suggest a potential benefit of EVT over BMM; however, current and future randomized clinical trials will better elucidate the efficacy of EVT in this patient population.

Is Endovascular Treatment Still Good for Ischemic Stroke in Real World?: A Meta-Analysis of Randomized Control Trial and Observational Study in the Last Decade. Stroke 2020; 51:3250-3263. [PMID: 32921259 DOI: 10.1161/strokeaha.120.029742] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/18/2022]
Abstract
BACKGROUND AND PURPOSE Although endovascular treatment (EVT) for acute ischemic stroke is classified as I evidence, outcomes after EVT in real-world practice appear to be less superior than those in randomized clinical trials (RCTs). Additionally, the effect of EVT is unclear compared with medical treatment (MT) for patients with mild symptoms defined by National Institutes of Health Stroke Scale score <6 or with severe symptoms defined by Alberta Stroke Program Early CT Score <6. METHODS Literatures were searched in big databases and major meetings from December 6, 2009, to December 6, 2019, including RCTs and observational studies comparing EVT against MT for patients with acute ischemic stroke. Observational studies were precategorized into 3 groups based on imaging data on admission: mild stroke group with National Institutes of Health Stroke Scale score <6, severe stroke group with Alberta Stroke Program Early CT Score <6 or ischemic core ≥50 mL, and normal stroke group for all others. Outcome was measured as modified Rankin Scale score of 0 to 2, mortality at 90 days, and symptomatic intracranial hemorrhage (sICH) at 24 hours. RESULTS Fifteen RCTs (n=3694) and 37 observational studies (n=9090) were included. EVT was associated with higher modified Rankin Scale 0 to 2 rate and lower mortality in RCTs and normal stroke group, whereas EVT was associated with higher sICH rate in normal stroke group, and no difference of sICH rate appeared between EVT and MT in RCTs. In severe stroke group, EVT was associated with higher modified Rankin Scale 0 to 2 rate and lower mortality, whereas no difference of sICH rate was found. In mild stroke group, there was no difference in modified Rankin Scale 0 to 2 rate between EVT and MT, whereas EVT was associated with higher mortality and sICH rate. CONCLUSIONS Evidence from RCTs and observational studies supports the use of EVT as the first-line choice for eligible patients corresponding to the latest guideline. For patients with Alberta Stroke Program Early CT Score <6, EVT showed superiority over MT, also in line with the guidelines. On the contrary to the guideline, our data do not support EVT for patients with National Institutes of Health Stroke Scale score <6.

Outcome of patients with large vessel occlusion in the anterior circulation and low NIHSS score. J Neurol 2020; 267:1651-1662. [PMID: 32062782 DOI: 10.1007/s00415-020-09744-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Revised: 01/31/2020] [Accepted: 02/03/2020] [Indexed: 01/01/2023]
Abstract
BACKGROUND Optimal management of patients with large vessel occlusion (LVO) and low NIHSS score is unknown, which was the aim to investigate in this study. METHODS This is a retrospective analysis of a prospective single tertiary care centre 14-year cohort of patients with LVO in the anterior circulation and NIHSS score ≤ 5 on admission. Outcome was analysed according to primary intended therapy. RESULTS Among 185 patients (median age 67.4 years), 52.4% received primary conservative therapy (including 26.8% secondary reperfusion in case of secondary neurological deterioration), 12.4% IV thrombolysis (IVT) only and 35.1% primary endovascular therapy (EVT). 95 (51.4%) patients experienced neurological deterioration until 3 months. Primary-IVT-only and primary-EVT compared to conservative-therapy patients had better 3 months' outcome (54.5% vs. 30.8%: adjustedOR 6.02; adjustedp = 0.004 for mRS 0-1 and 54.7% vs. 30.8%: adjustedOR 5.09; adjustedp = 0.002, respectively). Also mRS shift analysis favored primary-IVT-only and primary-EVT patients (adjustedOR 6.25; adjustedp = 0.001 and adjustedOR 3.14; adjustedp = 0.003). Outcome in primary-IVT-only vs. primary-EVT patients did not differ significantly. Patients who received secondary EVT because of neurological deterioration after primary-conservative-therapy had worse 3 months' outcome than primary-EVT patients (20.8% vs. 30.8%: adjustedOR 0.24; adjustedp = 0.047 for mRS 0-1 and adjustedOR 0.31; adjustedp = 0.019 in mRS shift analysis). Survival and symptomatic intracranial haemorrhage did not differ amongst groups. CONCLUSIONS Our data indicate that primary IVT and/or EVT may be better than primary conservative therapy in patients with LVO in the anterior circulation and low NIHSS score. Furthermore, primary EVT was better than secondary EVT in case of neurological deterioration. There is an unmet need for RCTs to find the optimal therapy for this patient group.
