Ameen D, Dewey HM, Khalil H. Strategies to reduce delays in delivering mechanical thrombectomy for acute ischaemic stroke - an umbrella review. Front Neurol 2024; 15:1390482. [PMID: 38952471 PMCID: PMC11215205 DOI: 10.3389/fneur.2024.1390482] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Accepted: 05/23/2024] [Indexed: 07/03/2024] Open
Abstract
Background Mechanical thrombectomy is a time-sensitive treatment, with rapid initiation and reduced delays being associated with better patient outcomes. Several systematic reviews reported on various interventions to address delays. Hence, we performed an umbrella review of systematic reviews to summarise the current evidence. Methods Medline, Embase, Cochrane Library and JBI were searched for published systematic reviews. Systematic Reviews that detailed outcomes related to time-to-thrombectomy or functional independence were included. Methodological quality was assessed using the JBI critical appraisal tool by two independent reviewers. Results A total of 17 systematic reviews were included in the review. These were all assessed as high-quality reviews. A total of 13 reviews reported on functional outcomes, and 12 reviews reported on time-to-thrombectomy outcomes. Various interventions were identified as beneficial. The most frequently reported beneficial interventions that improved functional and time-related outcomes included: direct-to-angio-suite and using a mothership model (compared to drip-and-ship). Only a few studies investigated other strategies including other pre-hospital and teamwork strategies. Conclusion Overall, there were various strategies that can be used to reduce delays in the delivery of mechanical thrombectomy with different effectiveness. The mothership model appears to be superior to the drip-and-ship model in reducing delays and improving functional outcomes. Additionally, the direct-to-angiosuite approach appears to be beneficial, but further research is required for broader implementation of this approach and to determine which groups of patients would benefit the most.

BMC Anesthesiol 2024; 24:126. [PMID: 38565990 PMCID: PMC10985877 DOI: 10.1186/s12871-024-02505-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 03/20/2024] [Indexed: 04/04/2024] Open
Abstract
BACKGROUND The comparison between sedation and general anesthesia (GA) in terms of all-cause mortality remains a subject of ongoing debate. The primary objective of our study was to investigate the impact of GA and sedation on all-cause mortality in order to provide clarity on this controversial topic. METHODS A systematic review and meta-analysis were conducted, incorporating cohort studies and RCTs about postoperative all-cause mortality. Comprehensive searches were performed in the PubMed, EMBASE, and Cochrane Library databases, with the search period extending until February 28, 2023. Two independent reviewers extracted the relevant information, including the number of deaths, survivals, and risk effect values at various time points following surgery, and these data were subsequently pooled and analyzed using a random effects model. RESULTS A total of 58 studies were included in the analysis, with a majority focusing on endovascular surgery. The findings of our analysis indicated that, overall, and in most subgroup analyses, sedation exhibited superiority over GA in terms of in-hospital and 30-day mortality. However, no significant difference was observed in subgroup analyses specific to cerebrovascular surgery. About 90-day mortality, the majority of studies centered around cerebrovascular surgery. Although the overall pooled results showed a difference between sedation and GA, no distinction was observed between the pooled ORs and the subgroup analyses based on RCTs and matched cohort studies. For one-year all-cause mortality, all included studies focused on cardiac and macrovascular surgery. No difference was found between the HRs and the results derived from RCTs and matched cohort studies. CONCLUSIONS The results suggested a potential superiority of sedation over GA, particularly in the context of cardiac and macrovascular surgery, mitigating the risk of in-hospital and 30-day death. However, for the longer postoperative periods, this difference remains uncertain. TRIAL REGISTRATION PROSPERO CRD42023399151; registered 24 February 2023.

Anaesthesia and haemodynamic management of acute ischaemic stroke patients before, during and after endovascular therapy. Anaesth Crit Care Pain Med 2020; 39:859-870. [PMID: 33039657 DOI: 10.1016/j.accpm.2020.05.020] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Revised: 05/16/2020] [Accepted: 05/26/2020] [Indexed: 11/29/2022]
Abstract
Endovascular therapy (EVT) is now standard of care for eligible patients with acute ischaemic stroke caused by large vessel occlusion in the anterior circulation. EVT can be performed with general anaesthesia (GA) or with monitored anaesthesia care, involving local anaesthesia with or without conscious sedation (LA/CS). Controversies remain regarding the optimal choice of anaesthetic strategy and observational studies suggested poorer functional outcome and higher mortality in patients treated under GA, essentially because of its haemodynamic consequences and the delay to put patients under GA. However, these studies are limited by selection bias, the most severe patients being more likely to receive GA and recent randomised trials and meta-analysis showed that protocol-based GA compared with LA/CS is significantly associated with less disability at 3 months. Unlike for intravenous thrombolysis, few data exist to guide management of blood pressure (BP) before and during EVT, but arterial hypotension should be avoided as long as the occlusion persists. BP targets following EVT should probably be adapted to the degree of recanalisation and the extent of ischaemia. Lower BP levels may be warranted to prevent reperfusion injuries even if prospective haemodynamic management evaluations after EVT are lacking.

Abstract
RATIONALE AND OBJECTIVES To describe the application of time maximum intensity projection CTA (t-MIP CTA) in acute ischemic stroke and compare t-MIP CTA and single-phase CTA (sCTA) in assessing collateral circulation and predicting prognosis. MATERIALS AND METHODS Twenty-nine acute ischemic stroke patients who underwent one-stop CT angiography (CTA)-CT perfusion scan were reviewed retrospectively. sCTA and t-MIP CTA were developed by CT perfusion scanning data. Image quality and collateral circulation were compared between the sCTA and t-MIP CTA groups. CT attenuation values, image noise, signal to noise , contrast to noise, and subjective image quality were obtained and compared between these two groups. The correlations of clinical prognosis and infarct volume with collateral status on t-MIP CTA and sCTA were analyzed, separately. Receiver operating characteristic curve was used to reveal the sensitivity and specificity of t-MIP CTA and sCTA in predicting outcome. RESULTS All images exhibited good quality for diagnosis. In objective evaluation, the noise level of t-MIP CTA was significantly lower than that of sCTA (p < 0.001). Vascular attenuation (signal to noise and contrast to noise) of t-MIP were higher than those of sCTA (all, p < 0.001). The collateral status on t-MIP CTA and sCTA were both negatively correlated with modified Rankin Scale scores (t-MIP CTA, r = -0.709, p < 0.001; sCTA, r = -0.551, p = 0.024) and the final infarction volume (t-MIP CTA, r = -0.716, p = 0.001; sCTA, r = -0.629, p = 0.003). t-MIP CTA was better for predicting prognosis (AUC, 0.956; sensitivity, 0.917; specificity, 0.941; p < 0.001) than sCTA (AUC, 0.824; sensitivity, 0.500; specificity, 0.941; p = 0.003). CONCLUSION In comparison with sCTA, t-MIP images showed higher image quality of intracranial vascularity and MIP could reveal vascular occlusion and evaluate collateral circulation more accurately. It was speculated that t-MIP could predict the prognosis more precisely.

Abstract
PURPOSE This study aims to analyze the efficacy of aspiration thrombectomy for large vessel occlusion of the posterior circulation, with an emphasis on comparison with stent retriever thrombectomy. METHODS A systematic review and meta-analysis were performed to analyze the outcomes of aspiration thrombectomy for acute posterior circulation stroke. For those studies that included data for both aspiration and stent-retriever thrombectomy, we additionally performed a second meta-analysis comparing their outcomes against each other. RESULTS A total of 17 articles were included. For the primary outcomes, the weighted pooled rate of mortality was 26.71% (95% confidence interval [CI] 19.35%-34.71%), modified Ranking Score (mRS) 0-2 at 3 months was 36.71 (95% CI 32.02%-41.52%), and successful recanalization 89.26% (95% CI 83.12%-94.31%). Primary stent retriever thrombectomy was inferior to primary aspiration thrombectomy for the outcomes of successful recanalization (odds ratio [OR] 0.57, 95% CI 0.36-0.91, P = 0.018), complete recanalization (OR 0.65, 95% CI 0.42-0.1.00, P = 0.048), procedure time (mean difference 28.17, 95% CI 9.47-46.87), and rate of embolization to new territory (OR 5.01, 95% CI 1.20-20.87, P = 0.027). No significant difference was seen for other outcomes. Further subgroup analysis suggests that for the outcome of recanalization, this may be dependent on the availability of second-line stent retriever thrombectomy. LIMITATIONS The included studies were observational in nature. There was unresolved heterogeneity in some of the outcomes. CONCLUSIONS There was no statistically significant difference seen for the primary outcomes of mortality and favorable outcome (mRS score 0-2) at 3 months. While superior rates of successful recanalization, complete recanalization, faster procedural time, and improved safety profile for primary aspiration thrombectomy were seen compared to primary stent retriever thrombectomy, this did not translate into superior clinical outcomes.

Abstract
In the United States, stroke ranks fifth among all causes of death and is the leading cause of serious long-term disability. The 2018 American Heart Association stroke care guidelines consider endovascular thrombectomy to be the standard of care for patients who have acute ischemic stroke in the anterior circulation when arterial puncture can be made within 6 hours of symptom onset or within 6-24 hours of symptom onset when specific eligibility criteria are satisfied. The aim of this 2-part review is to provide practical perspective on the clinical literature regarding anesthesia care of patients treated with endovascular thrombectomy. Part 1 (this article) reviews the development of endovascular thrombectomy and the determinants of endovascular thrombectomy effectiveness irrespective of method of anesthesia. The first aim of part 1 is to explain why rapid workflow and maintenance of blood pressure are necessary to help support the ischemic brain until, as a result of endovascular thrombectomy, reperfusion is accomplished. The second aim of part 1, understanding the nonanesthesia factors determining endovascular thrombectomy effectiveness, is necessary to identify numerous biases present in observational reports regarding anesthesia for endovascular thrombectomy. With this background, in part 2 (the companion to this article), the observational literature is briefly summarized, largely to identify its weaknesses, but also to develop hypotheses derived from it that have been recently tested in 3 randomized clinical trials of sedation versus general anesthesia for endovascular thrombectomy. In part 2, these 3 trials are reviewed both from a functional outcomes perspective (meta-analysis) and a methodological perspective, providing specifics regarding anesthesia and hemodynamic management. Part 2 concludes with a pragmatic approach to anesthesia decision making (sedation versus general anesthesia) and acute phase anesthesia management of patients treated with endovascular thrombectomy.

Effect of General Anesthesia vs. Conscious Sedation on the Outcomes of Acute Ischemic Stroke Patients After Endovascular Therapy: A Meta-Analysis of Randomized Clinical Trials.

Abstract
Background: Endovascular therapy is the standard treatment for acute ischemic stroke (AIS) patients caused by a large vessel occlusion in the anterior circulation, whereas the impacts of general anesthesia (GA) vs. conscious sedation (CS) for such procedures remained as a continued debate. Methods: We systematically searched PubMed, Embase, and ClinicalTrials.gov. We restricted our search to RCTs that examined the clinical outcomes of endovascular therapy with GA vs. CS. The Cochrane Risk of Bias Tool was used to assess study quality. Random-effects or fixed-effects meta-analyses were used for evaluating all outcomes. Results: A total of three randomized clinical trials met our inclusion criteria, with 368 individuals enrolled. Patients were randomized to receive GA or CS during endovascular therapy. In a meta-analysis of these trials, patients in the GA group were associated with favorable functional outcome (mRS score ≤ 2) compared with the CS group (pooled OR = 1.81, 95% CI: 1.17–2.79, P = 0.008). Besides, patients in the GA group had higher odds of successful reperfusion (pooled OR = 1.80, 95% CI: 1.05–3.08, P = 0.033), but no significant differences were seen in symptomatic intracranial hemorrhage (pooled OR = 0.54, 95% CI: 0.11–2.57, P = 0.308), vessel dissection or perforation (pooled OR = 1.38, 95% CI: 0.30–6.31, P = 0.679), migration of embolus to a new territory (pooled OR = 2.28, 95% CI: 0.89–5.87, P = 0.085), post-operative pneumonia (pooled OR = 1.74, 95% CI: 0.76–4.01, P = 0.149), and all-cause mortality at 90 days (pooled OR = 0.73, 95% CI: 0.43–1.26, P = 0.263) compared with the CS group. Conclusion: Performing endovascular therapy with GA, compared with CS, improves functional independence after 90 days significantly for patients with AIS caused by a large vessel occlusion in the anterior circulation. However, additional larger and multi-center randomized controlled trials to definitively confirm our findings are warranted for the limitation of the small sample size in this study.

Abstract
Despite several effective strategies of stroke prevention, the stroke epidemic still constitutes the leading cause of permanent disability. The recent series of well-designed, convincingly-positive randomized controlled trials of endovascular thrombectomy in stroke patients with large vessel occlusion launched a paradigm shift and a new era in acute stroke management. The present review provides an overview of the technical aspects of the procedure, discusses patient selection criteria, summarizes the current evidence from randomized trials about its efficacy and safety, and explores its implications in the organization of acute stroke care.

Abstract
Background Endovascular therapy is the standard of care for severe acute ischemic stroke caused by large‐vessel occlusion in the anterior circulation, but there is uncertainty regarding the optimal anesthetic approach during this therapy. Meta‐analyses of observational studies suggest that general anesthesia increases morbidity and mortality compared with conscious sedation. We performed a systematic review and meta‐analysis of randomized clinical trials to examine the effect of anesthetic strategy during endovascular treatment for acute ischemic stroke. Methods and Results Systematic review and meta‐analysis according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta‐Analyses) guidelines has been registered with the PROSPERO (International Prospective Register of Ongoing Systematic Reviews) (CRD42018103684). Medline, EMBASE, and CENTRAL databases were searched through August 1, 2018. Meta‐analyses were conducted using a random‐effects model to pool odds ratio with corresponding 95% CI. The primary outcome was 90‐day functional independence (modified Rankin Scale 0–2). In the results, 3 trials with a total of 368 patients were selected. Among patients with ischemic stroke undergoing endovascular therapy, general anesthesia was significantly associated with higher odds of functional independence (odds ratio 1.87, 95% CI 1.15–3.03, I2=17%) and successful recanalization (odds ratio 1.94, 95% CI 1.13–3.3) compared with conscious sedation. However, general anesthesia was associated with a higher risk of 20% mean arterial pressure decrease (odds ratio 10.76, 95% CI 5.25–22.07). There were no significant differences in death, symptomatic intracranial hemorrhage, anesthesiologic complication, intensive care unit length of stay, pneumonia, and interventional complication. Conclusions Moderate‐quality evidence suggests that general anesthesia results in significantly higher rates of functional independence than conscious sedation in patients with ischemic stroke undergoing endovascular therapy. Large randomized clinical trials are required to confirm the benefit.

Abstract
After being staggered by numerous negative trials in 2013, the interventional stroke community saw four years of vindication for mechanical thrombectomy showing efficacy and safety, even beyond a hopeful 6-8 hour window out to 24 h. A landmark set of five trials in 2015 provided a foundation upon which years of incremental follow-ups, meta-analyses and new breakthroughs would be built. With optimized devices for thrombectomy and image analysis, the neurointerventional community has turned to workflow and systemization in this new era of acute ischemic stroke treatment. The aim of this review is to chronicle the evidence in the epoch of positive trials, synthesize ancillary studies to these, and discuss the imminent challenges that remain.

Abstract
OBJECTIVE Our aim was to compare the clinical outcome of patients with ischaemic stroke with anterior large vessel occlusion treated with stent retrievers and/or contact aspiration mechanical thrombectomy (MT) under general anaesthesia (GA) or conscious sedation non-GA through a systematic review and meta-analysis. METHODS The literature was searched using PubMed, Embase and Cochrane databases to identify studies reporting on anaesthesia and MT. Using fixed or random weighted effect, we evaluated the following outcomes: 3-month mortality, modified Rankin Score (mRs) 0-2, recanalisation success (thrombolysis in cerebral infarction (TICI) ≥2b) and symptomatic intracerebral haemorrhagic (sICH) transformation. RESULTS We identified seven cohorts (including three dedicated randomised controlled trials), totalling 1929 patients (932 with GA). Over the entire sample, mortality, mRs 0-2, TICI≥2b and sICH rates were, respectively 17.5% (99% CI 9.7% to 29.6%; Q-value: 60.1; I2: 93%, 1717 patients), 42.1% (99% CI 33.3% to 51.7%; Q-value: 41.3; I2: 87.9%), 82.9% (99% CI 74.0% to 89.1%; Q-value: 20.7; I2: 80.6%, 1006 patients) and 5.5% (99% CI 2.8% to 10.8%; Q-value: 18.6; I2: 78.5%). MT performed in non-GA patients was associated with better 3-month functional outcome (pooled OR, 1.35; 99% CI 1.04 to 1.76; Q-value: 24.0; I2: 9.2%, 1845 patients) and lower 3-month mortality rate (pooled OR, 0.70; 99% CI 0.49 to 0.98; Q-value: 1.4; I2: 0%, 1717 patients; fixed weighted effect model) compared with GA. MT performed under conscious sedation non-GA had significantly shorter onset-to-recanalisation and onset-to-groin delay compared with GA, and recanalisation success and sICH were similar. CONCLUSION Non-GA during MT for anterior acute ischaemic stroke with current-generation stent retriever/aspiration devices is associated with better 3-month functional outcome and lower mortality rates. These unadjusted estimates are subject to biases and should be interpreted with caution.

Front Neurol 2018; 9:801. [PMID: 30319531 PMCID: PMC6167481 DOI: 10.3389/fneur.2018.00801] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2018] [Accepted: 09/05/2018] [Indexed: 12/02/2022] Open
Abstract
Background: Recent trials have proved the efficacy of mechanical thrombectomy over medical treatment for patients with acute ischemic stroke, with the balance of equivalent rates of adverse events. Stent retrievers were applied predominantly in most trials; however, the role of other thrombectomy devices has not been well validated. A direct aspiration first-pass technique (ADAPT) is proposed to be a faster thrombectomy technique than the stent retriever technique. This meta-analysis investigated and compared the efficacy and adverse events of first-line ADAPT with those of first-line stent retrievers in patients with acute ischemic stroke. Methods: A structured search was conducted comprehensively. A total of 1623 papers were found, and 4 articles were included in our meta-analysis. The Critical Appraisal Skills Programme tools were applied to evaluate the quality of studies. The primary outcome was defined as the proportion of patients with the Thrombolysis in Cerebral Ischemia (TICI) scale of 2b/3 at the end of all procedures. Secondary outcomes were the proportion of patients with functional independence (modified Rankin scale of 0–2) at the third month, the proportion of patients with the Thrombolysis in Cerebral Ischemia (TICI) scale of 2b/3 by primary chosen device, and the proportion of patients who received rescue therapies. Safety outcomes were the symptomatic intracranial hemorrhage (sICH) rate and the mortality rate within 3 months. Results: One randomized controlled trial, one prospective cohort study, and two retrospective cohort studies were included. No significant difference between these 2 strategies of management were observed in the primary outcome (TICI scale at the end of all procedures, odds ratio [OR] = 0.78), two secondary outcomes (functional independence at the third month, OR = 1.16; TICI scale by primary chosen device, OR = 1.25), and all safety outcomes (sICH rate, OR = 1.56; mortality rate, OR = 0.91). The proportion of patients who received rescue therapies was higher in the first-line ADAPT group (OR = 0.64). Conclusions: Among first-line thrombectomy devices for patients with ischemic stroke, ADAPT with the latest thrombosuction system was as efficient and safe as stent retrievers.

Abstract
Therapeutic effect of vascular interventional therapy and aspirin combined with defibrase in the treatment of cerebral ischemia in rat model were investigated. Ninety rats were selected to establish cerebral ischemia model. Animal models were randomly divided into observation group and control group, with 45 rats in each group. Rats in observation group were treated with vascular intervention, and control group was treated with aspirin combined with defibrase. Peak systolic velocity (Vs) and end-diastolic velocity (Vd) were compared between two groups before and after 12 months of treatment. Therapeutic effects were compared before and after 6 months, and before and after 12 months of treatment. Vs and Vd of vascular lesions in observation group at 12 months were reduced after treatment, and were significantly lower than those in control group (p<0.05). After treatment, Vs and Vd in observation group were significantly reduced (p<0.05). There was no significant difference in Vs and Vd values between the groups before treatment (p>0.05). NDS scores in observation group were significantly lower than those in control group at 6 months and 1 year after treatment (p<0.05). There were no significant changes in NDS score at 6 and 12 months after treatment in control group compared with pretreatment group (p>0.05). NDS in observation group was significantly reduced at 6 and 12 months after treatment compared with pretreatment level (p<0.05). One year after treatment, incidence of cerebral infarction and transient ischemic attack and mortality in observation group were significantly lower than those in the control group (p<0.05). Intracranial vascular interventional therapy can achieve satisfactory outcomes in the treatment of cerebral ischemia, and can effectively promote nerve function recovery, and reduce the incidence of cerebrovascular diseases and mortality.

Abstract
PURPOSE OF REVIEW Recent randomized clinical trials have demonstrated strong efficacy of endovascular therapy (EVT) for acute ischemic stroke (AIS) from large vessel occlusions; in the USA alone, tens of thousands of patients annually may benefit. The impact of the type of anesthesia used during mechanical thrombectomy on patient outcomes remains controversial. This review discusses the current literature on the effects of anesthesia type on patient outcome following endovascular stroke therapy. RECENT FINDINGS EVT is the standard of treatment for intracranial large vessel occlusions. Recent studies show that general anesthesia is associated with negative clinical outcome in AIS patients undergoing EVT. Two of the possible mechanisms of this finding are systolic hypotension and hypocapnia. However, the only published randomized controlled studies to date, sedation vs. intubation for endovascular stroke treatment and anesthesia during stroke showed no difference in short-term clinical outcome between EVT patients treated with general anesthesia and conscious sedation and improved longer-term outcome in the general anesthesia group. SUMMARY Retrospective reports, and the 2015 American Heart Association/American Stroke Association Guideline (focused update of the 2013 guidelines for the early management of patients with AIS regarding endovascular treatment) based on these reports, are in favor of sedation (conscious sedation) over general anesthesia for endovascular stroke thrombectomy. However, the two randomized controlled prospective studies published provide inconclusive evidence as to the best anesthetic practice for endovascular stroke therapy. More randomized clinical trials are needed to optimize anesthetic patient care in AIS.

Abstract
PURPOSE OF REVIEW Endovascular management of acute thrombotic strokes is a new management technique. Anaesthesia will play a key role in the management of these patients. To date there is no established method of managing these patients from an anaesthetic perspective. RECENT FINDINGS In 2015, five landmark studies popularized intra-arterial clot retrieval for ischaemic strokes. Since then there have been a number of small studies investigating the best anaesthetic technique, taking into account patient, technical, and clinical factors. This review summarizes these studies and discusses the different anaesthetic options, with their relative merits and pitfalls. SUMMARY There is a paucity of robust evidence for the best anaesthetic practice in this cohort of patients. Airway protection seems to be an issue in 2.5% of cases. Timing of the procedure is vital, and any delay may be detrimental to neurological outcome. In a survey of neurointerventionalists, the main concern they expressed was the potential delay to revascularization posed by anaesthesia. Patients complain of pain during mechanical clot retrieval if awake. The overall consensus seems to be favouring conscious sedation over general anaesthesia in the acute setting.

Abstract
BACKGROUND Endovascular mechanical thrombectomy (EMT) is the standard of care for eligible patients presenting with anterior circulation acute ischemic stroke (AIS) due to emergent large vessel occlusion (ELVO). The aim of this systematic review and meta-analysis is to compare the outcomes between patients undergoing general anesthesia (GA) versus conscious sedation (CS) for these procedures. METHODS A literature review was performed to identify studies reporting the EMT outcomes of AIS patients who underwent GA or CS for the procedure. Baseline, treatment, and outcomes data were analyzed. Good outcome was defined as a modified Rankin Scale score of 0-2 at 3 months, and successful reperfusion was defined as modified thrombolysis in cerebral infarction grade of 2b-3. RESULTS Nine studies, comprising a total of 1379 patients treated with GA (n = 761) or CS (n = 618) for EMT, were included. Based on pooled data, GA achieved good outcome in 35% and successful reperfusion in 81%, whereas CS achieved good outcome in 41% and successful reperfusion in 75%. Meta-analyses showed no significant differences in the rates of good outcome (P = 0.51) or successful reperfusion (P = 0.39) between the GA and CS groups. The rates of pneumonia were significantly higher in the GA group (21% vs. 11%; P = 0.01). CONCLUSIONS The use of either GA or CS during EMT for patients with anterior circulation acute ELVO does not yield significantly different rates of functional independence at 3 months.

Abstract
Background: Renal dysfunction (RD) may be associated with poor outcome in ischemic stroke patients treated with mechanical thrombectomy (MT), but data concerning this important and emerging comorbidity do not exist so far. Here, we investigated the influence of RD on postprocedural intracerebral hemorrhage (ICH), clinical outcome, and mortality in a large prospectively collected cohort of acute ischemic stroke patients treated with MT. Methods: Consecutive patients with anterior-circulation stroke treated with MT between October 2010 and January 2016 were included. RD was defined as glomerular filtration rate (GFR) <60 mL/min/1.73 m2. In a prospective database, clinical characteristics were recorded and brain images were analyzed for the presence of ICH after treatment in all patients. Clinical outcome was assessed by the modified Rankin Scale (mRS) after 3 months. To evaluate associations between clinical factors and outcomes uni- and multivariate regression analyses were conducted. Results: In total, 505 patients fulfilled all inclusion criteria (female: 49.7%, mean age: 71.0 years). RD at admission was present in 20.2%. RD patients were older and had cardiovascular risk factors more often. Multivariate regression analysis after adjustment for age, stroke severity, diabetes, hypertension, GFR, previous stroke, MT alone, or additional thrombolysis and recanalization results revealed that lower GFR was not independently associated with poor outcome (mRS 3-6; OR 1.13, 95% CI 0.99-1.28; p = 0.072) or ICH. However, lower GFR at admission was associated with a higher risk of mortality (OR 1.15, 95% CI 1.01-1.31; p = 0.038). Compared to admission, GFR values were higher at discharge (mean: 77.9 vs. 80.8 mL/min/1.73 m2; p = 0.046). Conclusions: We did not find evidence for an association of lower GFR with an increased risk of poor outcome and ICH, but lower GFR was a determinant of 90-day mortality after endovascular stroke treatment. Our findings encourage also performing MT in this relevant subgroup of acute ischemic stroke patients.

Abstract
BACKGROUND The optimal method of anaesthesia for endovascular therapy (EVT) in acute ischaemic stroke (AIS) has not been identified. Nordic departments of anaesthesiology may handle EVT cases for AIS differently. The aim of this survey was to describe the current practice patterns of Nordic anaesthesia departments in anaesthetic management of EVT in AIS. METHODS A survey consisting of 13 questions was sent to one qualified individual at all Nordic departments of anaesthesiology who manage anaesthesia for EVT interventions. The individual completed the questionnaire on behalf of their department. RESULTS Response rate was 100%. The majority of departments (84%) managed all EVT cases at their respective centres. Most departments have institutional guidelines on anaesthetic management (84%) including blood pressure management (63%) and were able to provide a 24-h immediate response to an EVT request (63%). Conscious sedation was favoured by 68% of the departments using a variety of sedation protocols. Propofol and remifentanil was preferred for GA (58%). Emergent conversion to GA due to uncontrolled patient movements or loss of airway was experienced by 82% and 35% of the departments, respectively. Majority of the departments (89%) responded that non-specialist anaesthetists occasionally handle EVT cases. CONCLUSIONS This survey indicates that the majority of Nordic anaesthesia departments who manage anaesthesia for EVT are able to provide immediate 24-h response to an EVT request. Most of these departments have institutional guidelines for EVT anaesthesia and haemodynamic management. Conscious sedation appears to be the preferred method of anaesthetic care.

Abstract
Background The recent success of several mechanical thrombectomy trials has resulted in a significant change in management for patients presenting with stroke. However, it is still unclear how to manage patients that present with stroke and low National Institutes of Health Stroke Scale (NIHSS) ≤5. We sought to review our experience of mechanical thrombectomy in patients with low NIHSS and confirmed M1 occlusion. Methods We retrospectively analysed our prospectively maintained database of all patients undergoing mechanical thrombectomy between January 2008 and August 2016. We identified 41 patients with confirmed M1 occlusion and low NIHSS (≤5) on admission to our hospital. We collected demographic, radiological, procedural and outcome data. Results The mean age of patients was 72±14, with 20 male patients. Associated medical conditions were common with hypertension seen in ∼80%. Just over 50% presented with NIHSS 4 or 5. The average ASPECTS score on admission was 8.8 (range 6–10), and the average clot length 10 mm. Angiographically Thrombolysis in Cerebral Infarction (TICI) ≥2b was obtained in 87.8% of patients. 7 patients had haemorrhage on follow-up, 2 of which were symptomatic. Of 40 patients with 90-day follow-up, 75% had modified Rankin Scale (mRS) score 0–2. There were 3 deaths at 90 days. Conclusions Mechanical thrombectomy in patients with low NIHSS and proximal large vessel occlusion is technically possible and carries a high degree of success with good safety profile. Patients with low NIHSS and confirmed occlusion should be considered for mechanical thrombectomy.
