Background and purpose: Asymptomatic intracranial hemorrhage (aICH) is a common occurrence after endovascular treatment (EVT) for acute ischemic stroke (AIS). The aims of this study were to address its impact on 3‐month functional outcome and to identify risk factors for aICH after EVT. Methods: Patients with AIS attributable to anterior circulation large vessel occlusion who underwent EVT were enrolled in a multicenter prospective registry. Based on imaging performed 22–36 h post‐EVT, we included patients with no intracranial hemorrhage (ICH) or aICH. Poor outcome defined as a 3‐month modified Rankin Scale (mRS) score 4–6 and overall 3‐month mRS score distribution were compared according to presence/absence of aICH, and aICH subtype using logistic regression. We assessed the risk factors of aICH using a multivariate logistic regression model. Results: Of the 1526 patients included in the study, 653 (42.7%) had aICH. Patients with aICH had a higher rate of poor outcome: odds ratio (OR) 1.88 (95% confidence interval [CI] 1.44–2.44). Shift analysis of mRS score found a fully adjusted OR of 1.79 (95% CI 1.47–2.18). Hemorrhagic infarction (OR 1.63 [95% CI 1.22–2.18]) and parenchymal hematoma (OR 2.99 [95% CI 1.77–5.02]) were associated with higher risk of poor outcome. Male sex, diabetes, coronary artery disease, baseline National Institutes of Health Stroke Scale score and Alberta Stroke Program Early Computed Tomography Score, number of passes and onset to groin puncture time were independently associated with aICH. Conclusions: Patients with aICH, irrespective of the radiological pattern, have a worse functional outcome at 3 months compared with those without ICH after EVT for AIS. The number of EVT passes and the time from onset to groin puncture are factors that could be modified to reduce deleterious ICH. [ABSTRACT FROM AUTHOR]

Background and purpose: Mechanical thrombectomy (MT) is the standard of care for patients with anterior circulation large vessel occlusion. Early neurological improvement (ENI), defined as a reduction of ≥ 8 on the National Institutes of Health Stroke Scale (NIHSS) compared with baseline score, or an NIHSS score of 0 or 1 at 24 h after MT, is a strong predictor of 3‐month favorable outcome in such patients. The impact of ENI after MT in stroke patients with basilar artery occlusion (BAO) on 3‐month outcome is not clear. We aimed to study the effects of ENI in patients with BAO. Methods: We performed a retrospective analysis of a multicenter prospective cohort of all consecutive stroke patients with BAO who underwent MT. We compared clinical outcomes between BAO patient groups according to ENI status. Multivariate analyses were performed to determine the impact of ENI on favorable 90‐day outcome (modified Rankin scale score 0–3) and to report factors contributing to ENI. Results: A total of 237 patients were included. ENI was observed in 70 patients (30%). Outcomes were significantly better in ENI‐positive patients, with 84% achieving favorable outcome (mRS score 0–3) at 3 months versus 30% for ENI‐negative patients (P < 0.0001). In multivariate analysis, ENI was an independent predictive factor associated with higher rates of favorable outcome {odds ratio (OR) 18.12 [95% confidence interval (CI) 3.95–83.10]; P = 0.0001}. Higher number of passes [OR 0.62 (95% CI 0.43–0.89); P = 0.010] and need for stenting [OR 0.27 (95% CI 0.07–0.95); P = 0.041] were negatively associated with ENI. Conclusion: Early neurological improvement on day 1 following MT for BAO is a strong independent predictor of a favorable 3‐month clinical outcome. [ABSTRACT FROM AUTHOR]

Background and purpose: Better characterization of the thrombus could be useful to determine acute ischaemic stroke (AIS) aetiology and predict response to thrombolysis and endovascular therapy (EVT). To test the hypothesis that susceptibility vessel sign (SVS) on baseline magnetic resonance imaging (MRI) is related to red blood cell (RBC) content of AIS thrombi, the total haemoglobin contents (HbCs) of AIS thrombi retrieved by EVT from patients with or without SVS or two‐layered SVS (TLSVS) were compared. Methods: Baseline MRI of 84 anterior AIS patients was reviewed by neuro‐radiologists blinded to clinical and biochemical data. Thrombi from these patients were retrieved by EVT and analysed for HbC by quantitative enzyme‐linked immunosorbent assay and measurement of haem concentration. Results: Susceptibility vessel sign and TLSVS were respectively observed in 85.7% and 50.0% of cases. The median HbC content was 253 µg/mg thrombus (interquartile range 177–333) and the median haem content was 219 µg/mg thrombus (131–264). Thrombus HbC and haem content were highly correlated with thrombus RBC content determined by flow cytometry (r = 0.94). Thrombi from patients with TLSVS weighed more [31.1 (16.5–68.3) mg vs. 17.7 (11.7–33.3) mg; P = 0.005] and had a higher HbC content [278 (221–331) µg/mg vs. 196 (139–301) µg/mg; P = 0.010] compared to thrombi from patients without TLSVS. There was no difference in thrombus weight or HbC content according to SVS status. Conclusions: Our study shows that TLSVS is significantly associated with a higher thrombus weight and RBC content, as determined by quantitative assays. [ABSTRACT FROM AUTHOR]

Background and purpose: Tandem anterior circulation lesions in the setting of acute ischemic stroke (AIS) are a complex endovascular situation that has not been specifically addressed in trials. We determined the predictors of successful reperfusion and good clinical outcome at 90 days after mechanical thrombectomy (MT) in patients with AIS with tandem lesions in a pooled collaborative study. Methods: This was a retrospective analysis of consecutive patients presenting to 18 comprehensive stroke centers with AIS due to tandem lesion of the anterior circulation who underwent MT. Results: A total of 395 patients were included. Successful reperfusion (modified thrombolysis in cerebral infarction score 2b–3) was achieved in 76.7%. At 90 days, 52.2% achieved a good outcome (modified Rankin Scale score 0–2), 13.8% suffered a parenchymal hematoma and 13.2% were dead. Lower National Institutes of Health Stroke Scale score [odds ratio (OR), 1.26; 95% confidence intervals (CI), 1.07–1.48, P = 0.004], Alberta Stroke Program Early CT Score ≥7 (OR, 2.00; 95% CI, 1.07–3.43, P = 0.011), intravenous thrombolysis (OR, 1.47; 95% CI, 1.01–2.12, P = 0.042) and stenting of the extracranial carotid lesion (OR, 1.63; 95% CI, 1.04–2;53, P = 0.030) were independently associated with successful reperfusion. Lower age (OR, 1.58; 95% CI, 1.26–1.97, P < 0.001), absence of hypercholesterolemia (OR, 1.77; 95% CI, 1.10–2.84, P = 0.018), lower National Institutes of Health Stroke Scale scores (OR, 2.04; 95% CI, 1.53–2.72, P < 0.001), Alberta Stroke Program Early CT Score ≥7 (OR, 2.75; 95% CI, 1.24–6.10, P = 0.013) and proximal middle cerebral artery occlusion (OR, 1.59; 95% CI, 1.03–2.44, P = 0.035) independently predicted a good 90‐day outcome. Conclusions: Intravenous thrombolysis and emergent stenting of the extracranial carotid lesion were predictors of a successful reperfusion after MT of patients with AIS with tandem lesion of the anterior circulation.

Background and purpose: The DAWN trial recently showed compelling evidence in treating late window and wake‐up stroke patients with thrombectomy using a clinical‐imaging mismatch. The aim was to evaluate the results of thrombectomy for unknown‐onset strokes (UOS) treated in our centres after a diffusion weighted imaging/fluid attenuated inversion recovery (DWI‐FLAIR) mismatch based selection. Methods: A multicentre, cohort study was performed of consecutive UOS treated by thrombectomy between 2012 and 2016. UOS with proximal anterior circulation occlusion discovered beyond 6 h from ‘last seen normal’ were compared with known‐onset strokes (KOS) for whom thrombectomy was started within 6 h from onset. Time intervals were recorded from first time found abnormal. Results were adjusted for age, diabetes, hypertension, National Institutes of Health Stroke Scale, site of occlusion, DWI Alberta Stroke Programme Early CT Score, intravenous thrombolysis and use of general anaesthesia. Results: Amongst 1246 strokes with anterior circulation occlusion treated by thrombectomy, 277 were UOS, with a ‘last time seen well’ beyond 6 h and DWI‐FLAIR mismatch, and 865 were KOS who underwent groin puncture within 6 h. Favourable outcome was achieved less often in UOS than KOS patients (45.2% vs. 53.9%,
P = 0.022). After pre‐specified adjustment, this difference was not significant (adjusted relative risk 0.91; 95% confidence interval 0.80–1.04;P = 0.17). No differences were found in secondary outcomes. Time intervals from first found abnormal were significantly longer in UOS. Conclusion: Thrombectomy of UOS with anterior circulation occlusion and DWI‐FLAIR mismatch appears to be as safe and efficient as thrombectomy of KOS within 6 h from onset. This pattern of imaging could be used for patient selection when time of onset is unknown. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background and Purpose: Vasospasm is a common iatrogenic event during mechanical thrombectomy (MT). In such circumstances, intra-arterial nimodipine administration is occasionally considered. However, its use in the treatment of iatrogenic vasospasm during MT has been poorly studied. We investigated the impact of iatrogenic vasospasm treated with intra-arterial nimodipine on outcomes after MT for large vessel occlusion stroke., Methods: We conducted a retrospective analysis of the multicenter observational registry Endovascular Treatment in Ischemic Stroke (ETIS). Consecutive patients treated with MT between January 2015 and December 2022 were included. Patients treated with medical treatment alone, without MT, were excluded. We also excluded patients who received another in situ vasodilator molecule during the procedure. Outcomes were compared according to the occurrence of cervical and/or intracranial arterial vasospasm requiring intraoperative use of in situ nimodipine based on operator's decision, using a propensity score approach. The primary outcome was a modified Rankin Scale (mRS) score of 0-2 at 90 days. Secondary outcomes included excellent outcome (mRS score 0-1), final recanalization, mortality, intracranial hemorrhage and procedural complications. Secondary analyses were performed according to the vasospasm location (intracranial or cervical)., Results: Among 13,678 patients in the registry during the study period, 434 received intra-arterial nimodipine for the treatment of MT-related vasospasm. In the main analysis, comparable odds of favorable outcome were observed, whereas excellent outcome was significantly less frequent in the group with vasospasm requiring nimodipine (adjusted odds ratio [aOR] 0.78, 95% confidence interval [CI] 0.63-0.97). Perfect recanalization, defined as a final modified Thrombolysis In Cerebral Infarction score of 3 (aOR 0.63, 95% CI 0.42-0.93), was also rarer in the vasospasm group. Intracranial vasospasm treated with nimodipine was significantly associated with worse clinical outcome (aOR 0.64, 95% CI 0.45-0.92), in contrast to the cervical location (aOR 1.37, 95% CI 0.54-3.08)., Conclusion: Arterial vasospasm occurring during the MT procedure and requiring intra-arterial nimodipine administration was associated with worse outcomes, especially in case of intracranial vasospasm. Although this study cannot formally differentiate whether the negative consequences were due to the vasospasm itself, or nimodipine administration or both, there might be an important signal toward a substantial clinical impact of iatrogenic vasospasm during MT., (© 2024 The Author(s).

- Abstract
Background and Purpose: Patients with acute ischaemic stroke and a large vessel occlusion who present to a non-endovascular-capable centre often require inter-hospital transfer for thrombectomy. Whether the inter-hospital transfer time is associated with 3-month functional outcome is poorly known., Methods: Acute stroke patients enrolled between January 2015 and December 2022 in the prospective French multicentre Endovascular Treatment of Ischaemic Stroke registry were retrospectively analysed. Patients with an anterior circulation large vessel occlusion transferred from a non-endovascular to a comprehensive stroke centre for thrombectomy were eligible. Inter-hospital transfer time was defined as the time between imaging in the referring hospital and groin puncture for thrombectomy. The relationship between transfer time and favourable 3-month functional outcome (modified Rankin Scale 0-2) was assessed through a mixed logistic regression model adjusting for centre and symptom-onset-to-referring-hospital imaging time, age, sex, diabetes, referring hospital National Institutes of Health Stroke Scale score, Alberta Stroke Programme Early Computed Tomography Score, occlusion site and intravenous thrombolysis use., Results: Overall, 3769 patients were included (median inter-hospital transfer time 161 min, interquartile range 128-195; 46% with favourable outcome). A longer transfer time was independently associated with lower rates of favourable outcome (p < 0.001). Compared to patients with transfer time below 120 min, there was a 15% reduction in the odds of achieving favourable outcome for transfer times between 120 and 180 min (adjusted odds ratio 0.85; 95% confidence interval 0.67-1.07), and a 36% reduction for transfer times beyond 180 min (adjusted odds ratio 0.64; 95% confidence interval 0.50-0.81)., Conclusions: A shorter inter-hospital transfer time is strongly associated with favourable 3-month functional outcome. A speedier inter-hospital transfer is of critical importance to improve outcome., (© 2024 The Authors.

- Abstract
Background and Purpose: Acute ischaemic stroke patients with cerebral small vessel disease (CSVD), including cerebral microbleeds (CMBs) and white matter hyperintensities (WMHs), have worse outcomes. The effect was investigated of two blood pressure strategies (intensive vs. standard) and blood pressure variability (BPV) after reperfusion according to CSVD burden in the BP TARGET trial., Methods: Patients with available magnetic resonance imaging at baseline were included. CMBs were described as absent or present and WMH severity was described according to the Fazekas classification (0-1, absent-mild; 2-3, moderate to severe). Outcomes consisted of any intracerebral hemorrhage (ICH) at 24 h and favorable outcome at 90 days (modified Rankin Scale score between 0 and 2)., Results: In all, 246 patients were included. The intensive systolic blood pressure target was not associated with lower rates of ICH or favorable outcome according to CSVD subgroups (all p values >0.35). Several BPV parameters were associated with increased odds of ICH in patients with CMBs but not in patients without CMBs (diastolic blood pressure coefficient of variation, odds ratio 2.06, 95% confidence interval [CI] 1.13-3.77, in patients with ≥1 CMB vs. 0.94, 95% CI 0.68-1.31, in patients without CMBs, p
het = 0.026). Several diastolic BPV parameters were associated with worse outcomes in patients with severe WMHs but not in patients without WMHs (diastolic blood pressure coefficient of variation, odds ratio 0.32, 95% CI 0.17-0.61, in patients with severe WMHs vs. 1.09, 95% CI 0.67-1.79, in patients without WMHs; phet = 0.003)., Conclusion: No effect of the intensive systolic blood pressure management strategy was found on ICH occurrence or functional outcome according to CSVD burden. BPV was associated with higher odds of ICH in patients with CMBs and worse outcome in patients with moderate-to-severe WMHs., (© 2023 European Academy of Neurology.)- Published

- Abstract
Background and Purpose: An early understanding of stroke mechanism may improve treatment and outcome in patients presenting with large vessel occlusion stroke (LVOS) treated with mechanical thrombectomy (MT). We aimed to investigate whether spontaneous external carotid artery (ECA) embolism detection during MT is associated with stroke etiology and clinical outcome., Methods: We retrospectively reviewed our prospectively maintained institutional database including consecutive patients with anterior circulation LVOS treated with MT between January 2015 and August 2020., Results: An ECA embolus was detected in 68 of 1298 patients (5.2%). The kappa coefficient for interobserver agreement was 0.89 (95% confidence interval [CI] 0.82-0.95). ECA embolism was significantly associated with intracranial internal carotid artery (ICA) occlusion (p < 0.001), cardioembolic etiology (p < 0.001) and a lower clot burden score (p < 0.001). Day-1 variation of National Institutes of Health Stroke Scale score (adjusted odds ratio [OR] -2.7, 95% CI -4.9 to 0.3; p = 0.021) and delta Alberta Stroke Program Early Computed Tomography Score (adjusted OR 0.9, 95% CI 0.2 to 1.5; p = 0.004) were worse among patients with ECA emboli. There was no significant difference in 90-day functional outcome between groups (adjusted OR 0.8, 95% CI 0.42 to 1.52; p = 0.50)., Conclusion: In patients with anterior circulation LVOS treated with MT, ECA embolism was significantly associated with cardioembolic etiology, high thrombus burden and proximal intracranial ICA occlusions. This underexplored angiographic pattern might provide a valuable etiologic clue to the underlying cause of anterior circulation LVOS and may also help determine the appropriate revascularization strategy., (© 2022 The Authors.

- Abstract
Background and Purpose: Despite continuous improvement and growing knowledge in the endovascular therapy of large vessel occlusion stroke (LVOS), mechanical thrombectomy (MT) still fails to obtain satisfying intracranial recanalization in 10% to 15% of cases. However, little is known regarding clinical and radiological outcomes among this singularly underexplored subpopulation undergoing failed MT. We aimed to investigate the outcome after failed MT and identify predictive factors of favorable outcome despite recanalization failure., Methods: We conducted a retrospective analysis of consecutive patients prospectively included in the ongoing observational multicenter Endovascular Treatment in Ischemic Stroke registry from January 2015 to September 2020. Patients presenting with anterior circulation LVOS treated with MT but experiencing failed intracranial recanalization defined as final modified Thrombolysis In Cerebral Infarction (mTICI) score of 0, 1 and 2a were included. Clinical and radiological outcomes were assessed along with the exploration of predictive factors of Day-90 favorable outcome., Results: The study population comprised 533 patients. Mean age was 68.8 ± 16 years, and median admission National Institutes of Health Stroke Scale (NIHSS) and Alberta Stroke Program Early Computed Tomography Score (ASPECTS) were 17 (IQR 12-21) and 7 (IQR 5-8), respectively. Favorable outcomes were observed in 85 patients (18.2%) and 186 died (39.0%). The rate of symptomatic intracranial hemorrhage was 14.1%. In multivariable analysis, younger age (odds ratio [OR] 0.96, 95% CI 0.94-0.98, p < 0.001), a lower admission NIHSS (OR 0.87, 95% CI 0.83-0.91, p < 0.001), a lower number of MT passes (OR 0.77, 95% CI 0.77-0.87, p < 0.001), a lower delta ASPECTS between initial and Day-1 imaging (OR 0.83, 95% CI 0.71-0.98, p = 0.026) and stroke etiology [significant difference among etiological subtypes (p = 0.024) with a tendency toward more favorable outcomes for dissection (OR 2.01, 95% CI 0.71-5.67)] were significantly associated with a 90-day favorable outcome., Conclusions: In this large retrospective analysis of a multicenter registry, we quantified the poor outcome after MT failure. We also identified factors associated with favorable outcome despite recanalization failure that might influence therapeutic management., (© 2022 The Authors.

- Abstract
Background and Purpose: The Blood Pressure Target in Acute Ischemic Stroke to Reduce Hemorrhage After Endovascular Therapy (BP TARGET) trial evaluated whether an intensive systolic blood pressure (SBP) target resulted in reduced rates of intracranial hemorrhage (ICH) after successful endovascular therapy (EVT) but did not assess the effect of blood pressure variability (BPV) on functional outcomes and ICH occurrence. We sought to evaluate this question in the BP TARGET trial., Methods: We performed a post hoc analysis of the BP TARGET trial and included patients with at least 50% of blood pressure (BP) recordings during the first 24 h after EVT. BPV parameters were SBP and diastolic BP (DBP) coefficient of variation (CV), standard deviation (SD), maximum-minimum (max-min), successive variation (SV), and time rate. The primary outcome was favorable functional outcome (3-month modified Rankin Scale between 0 and 2); the secondary outcome was the rate of ICH at 24 h., Results: We included 290 patients (mean number of BP measures = 30.4, SD = 8.0). BPV parameters (SBP
SD , SBPmax-min , SBPCV ) were higher in the intensive SBP target group. Only DBP BPV parameters were associated with worse functional outcomes in the unadjusted model (DBPSD , DBPmax-min , DBPCV , and DBPSV ), but not after adjustment. Higher SBPmax-min was associated with worse functional outcomes in Thrombolysis in Cerebral Infarction 2B patients (odds ratio [OR] = 0.62, 95% confidence interval [CI] = 0.38-1.02), but not in patients with complete reperfusion (OR = 1.27, 95% CI = 0.80-2.02, p for heterogeneity (phet =0.037). None of the BPV parameters was associated with ICH, regardless of the randomization group or the reperfusion grade., Conclusions: BPV was significantly higher in the intensive SBP target group but was not associated with functional outcome or ICH., (© 2021 European Academy of Neurology.)- Published

- Abstract
Background and Purpose: Tandem anterior circulation lesions in the setting of acute ischemic stroke (AIS) are a complex endovascular situation that has not been specifically addressed in trials. We determined the predictors of successful reperfusion and good clinical outcome at 90 days after mechanical thrombectomy (MT) in patients with AIS with tandem lesions in a pooled collaborative study., Methods: This was a retrospective analysis of consecutive patients presenting to 18 comprehensive stroke centers with AIS due to tandem lesion of the anterior circulation who underwent MT., Results: A total of 395 patients were included. Successful reperfusion (modified thrombolysis in cerebral infarction score 2b-3) was achieved in 76.7%. At 90 days, 52.2% achieved a good outcome (modified Rankin Scale score 0-2), 13.8% suffered a parenchymal hematoma and 13.2% were dead. Lower National Institutes of Health Stroke Scale score [odds ratio (OR), 1.26; 95% confidence intervals (CI), 1.07-1.48, P = 0.004], Alberta Stroke Program Early CT Score ≥7 (OR, 2.00; 95% CI, 1.07-3.43, P = 0.011), intravenous thrombolysis (OR, 1.47; 95% CI, 1.01-2.12, P = 0.042) and stenting of the extracranial carotid lesion (OR, 1.63; 95% CI, 1.04-2;53, P = 0.030) were independently associated with successful reperfusion. Lower age (OR, 1.58; 95% CI, 1.26-1.97, P < 0.001), absence of hypercholesterolemia (OR, 1.77; 95% CI, 1.10-2.84, P = 0.018), lower National Institutes of Health Stroke Scale scores (OR, 2.04; 95% CI, 1.53-2.72, P < 0.001), Alberta Stroke Program Early CT Score ≥7 (OR, 2.75; 95% CI, 1.24-6.10, P = 0.013) and proximal middle cerebral artery occlusion (OR, 1.59; 95% CI, 1.03-2.44, P = 0.035) independently predicted a good 90-day outcome., Conclusions: Intravenous thrombolysis and emergent stenting of the extracranial carotid lesion were predictors of a successful reperfusion after MT of patients with AIS with tandem lesion of the anterior circulation., (© 2018 EAN.)
