Systolic blood pressure reduction strategies in acute ischemic stroke patients following endovascular thrombectomy: a systematic review and meta-analysis. J Stroke Cerebrovasc Dis 2024; 33:107724. [PMID: 38636831 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107724] [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: 12/22/2023] [Revised: 04/09/2024] [Accepted: 04/15/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND AND AIMS There is no clear consensus on ideal systolic blood pressure (SBP) target post-endovascular thrombectomy (EVT) in patients with acute ischemic stroke. This study intends to investigate the relationship between reducing SBP and clinical outcomes and to determine the therapeutic efficacy of moderate and intensive SBP reduction post EVT. METHODS A comprehensive search was conducted across five electronic databases to identify studies relevant to our analysis. Data from these studies were then analyzed using pooled relative risk (RR) along with their corresponding 95 % confidence intervals (CI) for our categorical outcomes. functional independence at 90 days post-EVT was defined as a modified Rankin score (mRS) 0-2. RESULTS Our meta-analysis included eight studies with 2922 patients: 1376 patients were treated with intensive SBP reduction, 306 with moderate SBP reduction, and 1243 with standard SBP reduction. There was no difference in the risk of functional independence at 90 days post-EVT with both intensive-SBP reduction (target 120-140 mmHg, relative risk (RR) =1.05, 95 % CI 0.82, 1.34, p = 0.72) and moderate-SBP reduction (>160 mm Hg) (RR= 0.95, 95 % CI 0.69, 1.31, p = 0.76) compared with standard SBP reduction (>180 mm Hg). The risk of symptomatic intracranial hemorrhage (sICH) did not significantly differ between standard-SBP reduction and intensive-SBP reduction (RR = 0.93, 95 % CI 0.66, 1.31, p = 0.36) or moderate-SBP reduction (0.72 (95 % CI [0.28, 1.87], p = 0.50) groups, respectively. Intensive-SBP reduction significantly decreased the risk of hemicraniectomy. CONCLUSIONS We did not identify any difference in functional independence at 90 days in acute ischemic stroke patients with either intensive-SBP reduction or moderate-SBP reduction compared with standard SBP reduction post-EVT.

Intensive versus less intensive blood pressure targets after mechanical thrombectomy in acute ischemic stroke: a systematic review and network meta-analysis. Neurol Sci 2024:10.1007/s10072-024-07647-w. [PMID: 38880854 DOI: 10.1007/s10072-024-07647-w] [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: 03/01/2024] [Accepted: 06/11/2024] [Indexed: 06/18/2024]
Abstract
Hemodynamic management, specifically blood pressure, is essential to reduce mortality and preserve functional capacity. However, the literature is uncertain about the best blood pressure target to be adopted after performing mechanical thrombectomy in patients with acute ischemic stroke. Randomized clinical trials that compared blood pressure goals after mechanical thrombectomy were searched in the following databases: MEDLINE/PubMed, Embase, Scopus, Biomedcentral, and Cochrane Library. The last search was on September 19, 2023. The results obtained were used to construct network meta-analyses. A total of 1556 participants were enrolled from 4 randomized controlled trials (OPTIMAL-BP, ENCHANTED2/MT, BP-TARGET, BEST-II). The last article was not included in the network meta-analysis because it did not have common blood pressure targets. The outcomes compared were: mRS (modified Rankin scale), eTICI/mTICI scale scores, symptomatic and any intracerebral hemorrhage, post-intervention NIHSS, and post-intervention infarct volume. The outcomes using the mRS scale showed that better outcomes were reached with less intensive blood pressure targets when comparing < 120 mmHg vs. ≤ 180 mmHg, OR: 0.71 (95% CI 0.54 - 0.94), in the outcome of mRS 0-1. And for the mRS 0-2 outcome with comparisons < 120 mmHg vs. ≤ 180 mmHg, with OR: 0.59 (95% CI 0.44 - 0.77) and < 140 mmHg vs. ≤ 180 mmHg, with OR: 0.61 (95% CI 0.41 - 0.89). In patients with large vessel occlusion treated with mechanical thrombectomy and who achieved good reperfusion, intensive blood pressure lowering is not effective and might be harmful respect to non intensive blood pressure control in recanalized patients.

Abstract
BACKGROUND The relationship between post-endovascular thrombectomy (EVT) blood pressure (BP) and outcomes in patients with acute ischemic stroke (AIS) remains contentious. We aimed to explore whether this association differs with different cerebral perfusion statuses post-EVT. METHODS In a multicenter observational study of patients with AIS with large vessel occlusion who underwent EVT, we enrolled those who accepted CT perfusion (CTP) imaging within 24 hours post-EVT. We recorded post-EVT systolic (SBP) and diastolic BP. Patients were stratified into favorable perfusion and unfavorable perfusion groups based on the hypoperfusion intensity ratio (HIR) on CTP. The primary outcome was good functional outcome (90-day modified Rankin Scale score of ≤3). Secondary outcomes included early neurological deterioration, infarct size growth, and symptomatic intracranial hemorrhage. RESULTS Of the 415 patients studied (mean age 62 years, 75% male), 233 (56%) achieved good functional outcomes. Logistic regression showed that post-EVT HIR and 24-hour mean SBP were significantly associated with functional outcomes. Among the 326 (79%) patients with favorable perfusion, SBP <140 mmHg was associated with a higher percentage of good functional outcomes compared with SBP ≥140 mmHg (68% vs 52%; aOR 1.70 (95% CI 1.00 to 2.89), P=0.04). However, no significant difference was observed between SBP and functional outcomes in the unfavorable perfusion group. There was also no discernible difference between SBP and secondary outcomes across the different perfusion groups. CONCLUSIONS In patients with favorable perfusion post-EVT, SBP <140 mmHg was associated with good functional outcomes, which underscores the need for further investigations with larger sample sizes or a more individualized BP management strategy.

Abstract
OBJECTIVE There are limited data evaluating the optimum blood pressure (BP) goal post mechanical thrombectomy (MT) and its effect on outcomes of patients with large vessel occlusions (LVO). The objective of this study was to compare the efficacy and safety of intensive versus conventional BP control after reperfusion with MT via a systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS We searched PubMed and Embase to obtain articles related to BP control post MT through September 2023. The primary outcome was functional independence (modified Rankin Scale [mRS] 0-2) at 3 months, while secondary outcomes included excellent outcome (mRS 0-1), symptomatic intracranial hemorrhage (sICH), and mortality. RESULTS Four RCTs with 1,566 patients (762 randomized into intensive BP control vs. 806 randomized into conventional BP control) were included. Analysis showed that there was a lower likelihood of functional independence (mRS 0-2: odds ratio [OR]: 0.68, 95% confidence interval [CI] 0.51-0.91, p = 0.009) in the more intensive treatment group compared with the conventional treatment group. There was no statistically significant difference in achieving excellent outcome (mRS0-1: OR: 0.82, 95% CI: 0.63-1.07; p = 0.15), risk of sICH or mortality. INTERPRETATION This systematic review and meta- analysis Indicates that in patients who achieved successful MT for acute ischemic stroke with LVO, intensive BP control was associated with a lower likelihood of functional independence at 3 months without significant difference in likelihood of achieving excellent outcome, sICH risk, or mortality.

Abstract
BACKGROUND We performed a review of acute stroke trials to determine features associated with premature termination of trial enrollment, defined by the authors as not meeting preplanned sample size. METHODS AND RESULTS MEDLINE was searched for randomized clinical stroke trials published in 9 major clinical journals between 2013 and 2022. We included randomized clinical trials that were phase 2 or 3 with a preplanned sample size ≥100 and a time-to-treatment within 24 hours of onset for transient ischemic attack, ischemic stroke, or intracerebral hemorrhage. Data were abstracted on trial features including trial design, inclusion criteria, imaging, location and number of sites, masking, treatment complexity, control group (standard therapy, placebo), industry involvement, and preplanned stopping rules (futility and efficacy). Least absolute shrinkage and selection operator regression was used to select the most important factors associated with premature termination; then, a multivariable logistic regression was fit including only the least absolute shrinkage and selection operator selected variables. Of 1475 studies assessed, 98 trials met eligibility criteria. Forty-five (46%) trials were prematurely terminated, of which 27% were stopped for benefit/efficacy, 20% for lack of money/slow enrollment, 18% for futility, 16% for newly available evidence, 17% for other reasons, and 4% due to harm. Complex trials (adjusted odds ratio [aOR], 2.76 [95% CI, 1.13-7.49]), presence of a futility rule (aOR, 4.43 [95% CI, 1.62-17.91]), and exclusion of prestroke dependency (none/slight disability only; aOR, 2.19 [95% CI, 0.84-6.72] versus dependency allowed) were identified as the strongest predictors. CONCLUSIONS Nearly half of acute stroke trials were terminated prematurely. Broadening inclusion criteria and simplifying trial design may decrease the likelihood of unplanned termination, whereas planned futility analyses may appropriately terminate trials early, saving money and resources.

Abstract
Prospective clinical studies on blood pressure (BP) management targets after endovascular therapy (EVT) for acute ischemic stroke (AIS) have recently been published. Our objective was to assess the impact on clinical outcomes of BP management guided by established systolic BP (SBP) targets within the first 24 hours after successful EVT. Four randomized controlled trials (RCTs) including 1556 participants across 5 SBP target settings identified from 5 databases up to September 6, 2023 were included in this systematic review and meta-analysis. All the intensive SBP target groups in these RCTs were combined to facilitate head-to-head comparisons. Patients receiving intensive SBP management had lower risk of 90-day functional independence as assessed by the modified Rankin scale score (relative risk [RR], 0.81; 95% confidence interval [CI], 0.72 to 0.91; I2, 12%), excellent outcomes (RR,0.86; 95% CI, 0.75 to 0.99; I2, 7%), favorable outcomes (RR, 0.85; 95% CI, 0.78 to 0.92; I2, 0%), and quality of life (standardized mean difference, -0.22; 95% CI, -0.35 to -0.10; I2,0%). There were no differences in the probability of any intracerebral hemorrhage (RR, 1.04; 95% CI, 0.92 to 1.19; I2,0%), symptomatic intracerebral hemorrhage (RR, 1.10; 95% CI, 0.76 to 1.60; I2, 0%), stroke-related death (RR, 1.16; 95% CI, 0.80 to 1.68; I2, 0%), or parenchymal hematoma (RR, 1.71; 95% CI, 0.74 to 3.98; I2, 47%) between SBP targets. This meta-analysis provides evidence from RCTs suggesting that intensive SBP control (target<160 mm Hg) may be detrimental to clinical outcomes in AIS patients with successful reperfusion after EVT.

Abstract
The management of blood pressure variability (BPV) in acute stroke presents a complex challenge with profound implications for patient outcomes. This narrative review examines the role of BPV across various stages of acute stroke care, highlighting its impact on treatment strategies and prognostic considerations. In the prehospital setting, while guidelines lack specific recommendations for BP management, emerging evidence suggests a potential link between BPV and outcomes. Among ischaemic stroke patients who are ineligible for reperfusion therapies, BPV independently influences functional outcomes, emphasising the need for individualised approaches to BP control. During intravenous thrombolysis and endovascular therapy, the intricate interplay between BP levels, recanalisation status, and BPV is evident. Striking a balance between aggressive BP lowering and avoiding hypoperfusion-related complications is essential. Intracerebral haemorrhage management is further complicated by BPV, which emerges as a predictor of mortality and disability, necessitating nuanced BP management strategies. Finally, among patients with acute subarachnoid haemorrhage, increased BPV may be correlated with a rebleeding risk and worse outcomes, emphasizing the need for BPV monitoring in this population. Integration of BPV assessment into clinical practice and research protocols is crucial for refining treatment strategies that are tailored to individual patient needs. Future studies should explore novel interventions targeting BPV modulation to optimise stroke care outcomes.

Abstract
BACKGROUND This study sought to determine whether intensive blood pressure (BP) control for patients with successful reperfusion following acute ischemic stroke (AIS) is beneficial, compared to conventional BP management. METHODS PubMed, Embase, and Cochrane databases were systematically searched for randomized controlled trials (RCTs) on the subject. The studied outcomes included dependency or death at 90 days (modified Rankin Scale [mRS] 3-6); severe disability at 90 days (mRS 3-5); mortality at 90 days; and symptomatic intracranial hemorrhage. Odds ratios (OR) with 95% confidence intervals were used to compare the treatment effects for categorical outcomes. We employed a fixed-effect model for analyses with low heterogeneity (I2 < 25%) and a random-effects model for analyses with higher heterogeneity. RESULTS A total of 1519 patients were included, with 50% (n = 760) receiving intensive BP control (systolic BP < 140 mmHg). Functional disability or death at 90 days was significantly higher in the intensive group (54.9%) compared to the conventional treatment group (44.1%) (OR = 1.51; 95% Confidence Interval [CI]: 1.15-1.96; p = 0.003; I2 = 29%). Severe functional disability (mRS 3-5) was significantly higher in the intensive group (30.6% vs. 43.5%, OR = 1.75; 95%CI = 1.36-2.25; p < 0.0001; I2 = 0%). There was no difference in symptomatic intracranial hemorrhage (OR = 1.13; 95%CI = 0.76-1.67) or mortality (OR = 1.22; 95%CI = 0.9-1.64). CONCLUSIONS Intensive BP control is harmful in patients who underwent EVT for AIS and achieved successful reperfusion. It yields higher rates of functional dependence, with no differences in mortality or symptomatic intracranial hemorrhage.

Intensive Blood Pressure Control After Endovascular Thrombectomy for Acute Ischemic Stroke: a Systematic Review and Meta-Analysis. Clin Neuroradiol 2024:10.1007/s00062-024-01391-6. [PMID: 38453701 DOI: 10.1007/s00062-024-01391-6] [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: 11/25/2023] [Accepted: 01/22/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND AND PURPOSE Optimal clinical outcome with successful recanalization from endovascular thrombectomy (EVT) requires optimal blood pressure (BP) management. We aimed to evaluate the efficacy and safety of the intensive BP target (< 140 mm Hg) versus the standard BP target (< 180 mm Hg) after EVT for acute ischemic stroke. METHODS We conducted a systematic review and meta-analysis synthesizing evidence from randomized controlled trials (RCTs) obtained from PubMed, Embase Cochrane, Scopus, and WOS until September 7th, 2023. We used the fixed-effect model to report dichotomous outcomes using risk ratio (RR) and continuous outcomes using mean difference (MD), with a 95% confidence interval (CI). PROSPERO ID CRD42023463206. RESULTS We included four RCTs with 1559 patients. There was no difference between intensive BP and standard BP targets regarding the National Institutes of Health Stroke Scale (NIHSS) change after 24 h [MD: 0.44 with 95% CI (0.0, 0.87), P = 0.05]. However, the intensive BP target was significantly associated with a decreased risk of excellent neurological recovery (mRS ≤ 1) [RR: 0.87 with 95% CI (0.76, 0.99), P = 0.03], functional independence (mRS ≤ 2) [RR: 0.81 with 95% CI (0.73, 0.90), P = 0.0001] and independent ambulation (mRS ≤ 3) [RR: 0.85 with 95% CI (0.79, 0.92), P < 0.0001]. CONCLUSIONS An intensive BP target after EVT is associated with worse neurological recovery and significantly decreased rates of functional independence and independent ambulation compared to the standard BP target. Therefore, the intensive BP target should be avoided after EVT for acute ischemic stroke.

Abstract
OBJECTIVE The objective of this study is to comprehensively examine the available data on the efficacy and safety of intensive blood pressure lowering (IBPL) compared to standard blood pressure control (SBPC) in patients with acute ischemic stroke following reperfusion therapy. METHODS A comprehensive search was conducted using 4 databases, including PubMed, Cochrane, Embase, and Web of Science to collect relevant articles from inception to December 2023. The endpoints were the condition of the patient measured by the modified Rankin scale (mRS, range value from 0 [no symptoms] to 6 [death]) at 90 days, symptomatic intracranial hemorrhage, death within 90 days, recurrent ischemic stroke, and intracranial hemorrhage (ICH). RESULTS Seven eligible studies involving 4499 participants (2218 patients in IBPL group and 2281 patients in SBPC group) were included in the analysis. Both groups demonstrated similar baseline characteristics. Within the endovascular therapy (EVT) subgroup, the IBPL group exhibited worse mRS than in SBPC group. After EVT, different IBPL targets showed worse outcomes in the mRS for the SBP <140 mmHg and SBP <120 mmHg subgroups, with no difference between IBPL and SBPC groups in the SBP <130 mmHg subgroup. In the intravenous thrombolysis subgroup, although the IBPL group exhibited less ICH, the long-term functional outcomes were not improved significantly. CONCLUSIONS The IBPL group exhibited a less favorable functional outcome after EVT. Moreover, no worse functional outcomes were noticed in the SBP <130 mmHg subgroup after EVT. However, the functional outcome was similar after intravenous thrombolysis.

Abstract
BACKGROUND Endovascular thrombectomy (EVT) has been proven as the standard treatment for acute ischemic stroke (AIS) patients due to large vessel occlusion (LVO). However, the ideal anesthetic strategy during EVT still remains unclear. Therefore, this systematic review and meta-analysis aimed to determine the optimal anesthetic modality for patients with AIS undergoing EVT based on current randomized controlled trials (RCTs). METHODS The databases Medline (via PubMed), EMBASE, Web of Science, and the Cochrane Library were searched for RCTs comparing general anesthesia (GA) and conscious sedation (CS) in AIS patients undergoing EVT. The primary outcome was a favorable functional outcome at 90 days postintervention. Data analysis was conducted using the Review Manager software (RevMan V.5.3). RESULTS Eight RCTs involving 1199 patients were included. There was no significant difference between GA and CS group in the rate of functional independence (risk ratio (RR) = 1.10, 95% confidence interval (CI) = 0.96 to 1.25; p = 0.17; I2 = 30%). Compared with the CS group, the GA group attained a higher successful recanalization rate (RR = 1.14, 95% CI = 1.08 to 1.20; p < 0.00001; I2 = 17%). In addition, patients in the GA were associated with a higher rate of hypotension (RR = 1.87, 95% CI = 1.44 to 2.41; p < 0.00001; I2 = 66%) and a higher incidence of pneumonia (RR = 1.38, 95% CI = 1.05 to 1.8; p = 0.02; I2 = 37%). CONCLUSION For AIS patients receiving EVT, the choice of anesthetic modality did not influence the 3-month neurological outcome while GA is superior to CS in terms of successful reperfusion rate. Moreover, the patients in the GA group were at a higher risk of developing hypotension and pneumonia. Further studies are required to provide more sufficient evidence.

Abstract
Importance Endovascular thrombectomy (EVT) is standard treatment for acute ischemic stroke (AIS) due to large-vessel occlusion (LVO), but optimal post-EVT blood pressure (BP) control remains debated. Objective To assess the association of different systolic BP targets following EVT with functional outcomes, mortality, and complications in patients with AIS due to LVO. Data Sources Systematic review and meta-analysis of databases (PubMed, Embase, Web of Science, Scopus, and Cochrane Library) to September 8, 2023. Study Selection Inclusion criteria consisted of randomized clinical trials examining post-EVT management of systolic BP in patients with AIS and LVO comparing intensive vs conventional targets. Nonrandomized studies, observational studies, noninterventional trials, meeting abstracts, duplicate studies, studies with overlapping data, and non-English language studies were excluded. Two authors independently applied these criteria through a blinded review, with discrepancies resolved through consensus. The risk of bias in the included studies was assessed using the revised tool for assessing risk of bias in randomized trials. Data Extraction and Synthesis This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline. Three authors extracted data regarding study characteristics, baseline patient data, and outcomes of interest. The pooled data were analyzed using a random-effects meta-analysis. Main Outcomes and Measures Rates of functional independence, 90-day mortality, symptomatic intracranial hemorrhage, and hypotensive events. Results A total of 4 randomized clinical trials with 1571 initially enrolled patients were included in the analysis. Lower functional independence rates were observed in the intensive control group (relative risk [RR], 0.81 [95% CI, 0.67-0.98]). No significant differences were found in 90-day mortality (RR, 1.18 [95% CI, 0.92-1.52]), symptomatic intracranial hemorrhage (RR, 1.12 [95% CI, 0.75-1.67]), or hypotensive events (RR, 1.80 [95% CI, 0.37-8.76]). There was minimal heterogeneity among the studies included in the functional independence outcome (I2 = 13% and τ2 = 0.003), which was absent among other outcomes (I2 = 0 and τ2 = 0). Conclusions and Relevance These findings suggest that intensive post-EVT BP reduction does not yield benefits and may carry risks. While awaiting the results of additional ongoing trials, a conservative BP management strategy after endovascular recanalization is favored in daily practice.

Int J Surg 2024; 110:974-983. [PMID: 38052025 PMCID: PMC10871655 DOI: 10.1097/js9.0000000000000925] [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: 08/10/2023] [Accepted: 11/09/2023] [Indexed: 12/07/2023]
Abstract
BACKGROUND Previous literature has established an association between acute silent ischemic lesions (ASILs) and elevated susceptibility to future adverse clinical outcomes. The present study endeavors to scrutinize the prognostic significance of preprocedural ASILs, as detected through diffusion-weighted imaging and apparent diffusion coefficient metrics, in relation to subsequent adverse events-namely, stroke, myocardial infarction, and all-cause death-following carotid revascularization in a cohort of patients with symptomatic carotid stenosis. MATERIALS AND METHODS Subjects were extracted from a comprehensive retrospective dataset involving symptomatic carotid stenosis cases that underwent carotid revascularization at a tertiary healthcare institution in China, spanning January 2019 to March 2022. Of the 2663 initially screened patients (symptomatic carotid stenosis=1600; asymptomatic carotid stenosis=1063), a total of 1172 individuals with symptomatic carotid stenosis were retained for subsequent analysis. Stratification was implemented based on the presence or absence of ASILs. The primary endpoint constituted a composite measure of in-hospital stroke, myocardial infarction, or all-cause death. Both carotid endarterectomy (CEA) and carotid artery stenting (CAS) treatment modalities were individually subjected to propensity score-matched analyses. RESULTS Among the 584 subjects who underwent CEA, 91 ASIL-positive and 91 ASIL-negative (NASIL) cases were propensity score-matched. Notably, the ASIL cohort demonstrated a statistically significant augmentation in the risk of primary outcomes relative to the NASIL group [10.99 vs. 1.10%; absolute risk difference, 9.89% (95% CI: 3.12-16.66%); RR, 10.00 (95% CI: 1.31-76.52); P =0.01]. Similarly, within the 588 CAS-treated patients, 107 ASIL-positive and 107 NASIL cases were matched, revealing a correspondingly elevated risk of primary outcomes in the ASIL group [9.35 vs. 1.87%; absolute risk difference, 7.48% (95% CI: 1.39-13.56%); RR, 5.00 (95% CI: 1.12-22.28); P =0.02]. CONCLUSIONS ASILs portend an elevated risk for grave adverse events postcarotid revascularization, irrespective of the specific revascularization technique employed-be it CEA or CAS. Thus, ASILs may serve as a potent biomarker for procedural risk stratification in the context of carotid revascularization.

Abstract
BACKGROUND AND PURPOSE The optimal blood pressure (BP) control after successful endovascular thrombectomy (EVT) in acute ischemic stroke (AIS) with large vessel occlusion (LVO) remains debatable. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) that evaluate the efficacy and safety of standard BP control (with systolic BP ≤180 mm Hg) versus intensive BP control (systolic BP <140 mm Hg) during the 24 hours after successful EVT in AIS with LVO. METHODS PubMed, Scopus, the Cochrane Central Register of Controlled Trials, and Embase were searched to identify relevant trials. The crude odds ratio (OR) and 95% confidence interval (CI) were calculated and estimates using random-effects models were pooled. This meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO ID: CRD42023450673). RESULTS Four RCTs involving 1,559 participants were included. Regarding efficacy outcomes, intensive BP control was associated with a lower likelihood of functional independence (OR: 0.68; 95% CI: 0.51-0.91 for modified Rankin Scale [mRS] ≤2) and walking without assistance (OR: 0.65; 95% CI: 0.53-0.81 for mRS ≤3). For safety outcomes, consistent with the efficacy findings, intensive BP control was significantly associated with severe disability or death (mRS 5 or 6) (OR: 1.34; 95% CI: 1.07-1.69). However, there were no significant differences including all-cause mortality, any intracerebral hemorrhage (ICH), symptomatic ICH, parenchymal hematoma type 2, and stroke recurrence. CONCLUSION While all four RCTs were conducted to demonstrate the superiority of intensive BP control over standard BP control, standard BP control may be beneficial for the outcome after EVT for AIS with LVO without increasing adverse safety outcomes. Caution should be needed with the application of intensive BP control during the 24 hours following successful recanalization after EVT.

Abstract
As the majority of large vessel occlusion (LVO) patients are not treated with revascularization therapies or efficiently revascularized, complementary management strategies are needed. In this article we explore the importance of cerebral autoregulation (CA) assessment in the prediction and/or modification of infarct growth and hemorrhagic transformation. In patients with LVO, these are important factors that affect prognosis. A systematic search of the PubMed, EMBASE databases and a targeted Google search was conducted, resulting in the inclusion of 34 relevant articles. There is an agreement that CA is impaired in patients with LVO; several factors have been identified such as time course, revascularization status, laterality, disease subtype and location, some of which may be potentially modifiable and affect outcomes. The personalized CA assessment of these patients suggests potential for better understanding of the inter-individual variability. Further research is needed for the development of more accurate, noninvasive techniques for continuous monitoring and personalized thresholds for CA.

Abstract
The volume of infarcted tissue in patients with ischemic stroke is consistently associated with increased morbidity and mortality. Initial studies of endovascular thrombectomy for large-vessel occlusion excluded patients with established large-core infarcts, even when large volumes of salvageable brain tissue were present, due to the high risk of hemorrhagic transformation and reperfusion injury. However, recent retrospective and prospective studies have shown improved outcomes with endovascular thrombectomy, and several clinical trials were recently published to evaluate the efficacy of endovascular management of patients presenting with large-core infarcts. With or without thrombectomy, patients with large-core infarcts remain at high risk of in-hospital complications such as hemorrhagic transformation, malignant cerebral edema, seizures, and others. Expert neurocritical care management is necessary to optimize blood pressure control, mitigate secondary brain injury, manage cerebral edema and elevated intracranial pressure, and implement various neuroprotective measures. Herein, we present an overview of the current and emerging evidence pertaining to endovascular treatment for large-core infarcts, recent advances in neurocritical care strategies, and their impact on optimizing patient outcomes.
