Background: Cardioembolic stroke is associated with a higher rate of functional limitation, which may be related to the larger ischemic lesion size. Endovascular therapy (EVT) for acute stroke caused by large vessel occlusion reduces severe disabilities. Objectives: We aimed to investigate the relationship between EVT and decompressive hemicraniectomy (DH) in patients with cardioembolic proximal intracranial occlusion in the anterior circulation (CPIOAC) using the data from the Recovery by Endovascular Salvage for Cerebral Ultra-acute Embolism (RESCUE)-Japan Registry 2. Methods: Among 2,420 patients in the RESCUE-Japan Registry 2, 555 patients aged 20–80 years with acute cardioembolic occlusion of the internal carotid artery and/or the first segment of the middle cerebral artery were included. The primary outcome was DH. Secondary outcomes were any type of intracranial hemorrhage, symptomatic intracranial hemorrhage indicating neurological worsening of >4 points on the National Institutes of Health Stroke Scale within 72 h after the onset of stroke, and recurrence of stroke or transient ischemic attack (TIA) within 90 days. Results: The median age was 73 years (66–77 years), and 360 patients (65%) were male. DH was performed in 1 of 374 patients in the EVT group and 5 of 181 patients in the no-EVT group (p = 0.032). The incidence of any type of intracranial hemorrhage and symptomatic intracranial hemorrhage within 72 h and recurrence of stroke or TIA within 90 days were similar between both groups. Conclusions: EVT may reduce DH in patients with CPIOAC without increasing intracranial hemorrhage.

Abstract Background and purpose: A fraction 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 as a National Institutes of Health Stroke Scale score increase of ≥ 4 points within 24 hours 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 (CI), 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 may predict sICH after endovascular therapy.

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.

Background and Purpose: Diffusion weighted imaging-fluid attenuated inversion recovery (DWI-FLAIR) mismatch was well recognized as an early sign of acute ischemic stroke lesions. In the era of mechanical thrombectomy (MT), DWI-FLAIR mismatch could be a good marker for candidates of MT. We thus investigated the association between DWI-FLAIR mismatch and functional outcomes in patients who received MT for acute large vessel occlusion (LVO). Methods: We conducted historical cohort study in consecutive patients who were evaluated by MRI for suspected stroke at single stroke center. We enrolled patients with occlusion of the ICA or M1 or M2 segment of MCA who were underwent MT within 24 hours after the last known to be well. FLAIR negative was defined when a visible acute ischemic lesion was present on DWI without traceable parenchymal hyperintensity on FLAIR. We estimated the adjusted OR of FLAIR negative for moderate outcome defined as mRS 0-3 at 90 days after onset. We also estimated the adjusted OR for symptomatic intracranial hemorrhage within 72 hours and mortality at 90 days. Results: Among 380 patients who received MT for acute LVO, 202 patients were included in this study. Patients with FLAIR negative was 146 (72%), and the rest were FLAIR positive. Patients with FLAIR negative had significantly higher baseline NIHSS (median 16 vs 13, p=0.01), more transferred-in (78% vs 63%, p=0.02), more intravenous thrombolysis (IVT) (45% vs 18%, P=0.0003), more cardioembolism (69% vs 54%, p=0.03), and shorter times from the onset to hospital door (median 175 vs 371 minutes, p<0.0001). Patients with FLAIR negative had more moderate outcome than the counterparts (61% vs 52%, p=0.24). The adjusted OR of FLAIR negative compared to positive was 2.97 (95%CI, 1.33-6.60, p=0.008). Symptomatic intracranial hemorrhage within 72 hours was less frequent in the FLAIR negative group (10% vs 20%, p=0.06), with an adjusted OR of 0.34 (95%CI, 0.13-0.87, p=0.02). Conclusions: DWI-FLAIR mismatch was associated with better functional outcome in patients received MT for acute LVO at 90 days. DWI-FLAIR mismatch should be a good marker for the candidate of MT for acute LVO. Future randomized trial to evaluate the effectiveness of MRI-based MT using DWI-FLAIR mismatch should be considered.

Background and Purpose: Endovascular therapy is the standard of care in the treatment of acute ischemic stroke due to large-vessel occlusion. A direct association between the number of device passes and the occurrence of symptomatic intracranial hemorrhage (SICH) has been suggested. This study represents an in-depth investigation of the hypothesis that >3 retrieval attempts is associated with an increased rate of SICH in a large multicenter patient cohort. Methods: Two thousand six hundred eleven patients from the prospective German Stroke Registry were analyzed. Patients who received Endovascular therapy for acute large-vessel occlusion of the anterior circulation with known admission National Institutes of Health Stroke Scale and Alberta Stroke Program Early CT Score, final Thrombolysis in Cerebral Infarction, and number of retrieval passes were included. The primary outcome was defined as SICH. The secondary outcome was any type of radiologically confirmed intracranial hemorrhage within the first 24 hours. Multivariate mixed-effects models were used to adjust for cluster effects of the participating centers, as well as for confounders. Results: Five hundred ninety-three patients fulfilled the inclusion criteria. The median number of retrieval passes was 2 [interquartile range, 1–3]. SICH occurred in 26 cases (4.4%), whereas intracranial hemorrhage was identified by neuroimaging in 85 (14.3%) cases. More than 3 retrieval passes was the strongest predictor for SICH (odds ratio, 3.61 [95% CI, 1.38–9.42], P =0.0089) following adjustment for age, admission National Institutes of Health Stroke Scale, admission Alberta Stroke Program Early CT Score, and Thrombolysis in Cerebral Infarction, as well as time from symptom onset to flow restoration. Baseline Alberta Stroke Program Early CT Score of 8 to 9 (odds ratio, 0.26 [95% CI, 0.07–0.89], P =0.032) or 10 (odds ratio, 0.21 [95% CI, 0.06–0.78], P =0.020) were significant protective factors against the occurrence of SICH. Conclusions: More than 3 retrieval attempts is associated with a significant increase in SICH risk, regardless of patient age, baseline National Institutes of Health Stroke Scale, or procedure time. This should be considered when deciding whether to continue a procedure, especially in patients with large baseline infarctions.

Introduction: Five RCTs demonstrated the superiority of endovascular therapy (EVT) over best medical management (MM) for acute ischemic strokes (AIS) with large vessel occlusion (LVO) in the anterior circulation. Patients with M2 occlusions, however, were underrepresented (95 randomized; 51 EVT treated). Evidence from RCTs of the benefit of EVT for M2 occlusions is lacking, as reflected in the recent AHA guidelines. Methods: A retrospective cohort was pooled from 10 academic centers from 1/12 to 4/15 of AIS patients with LVO isolated to M2 presenting within 8 hours from last known normal (LKN). Patients were divided into EVT and MM groups. Primary outcome was 90 day mRS (good outcome 0-2); secondary outcome was sICH. Logistic regression compared the 2 groups. Univariate and multivariate analyses evaluated predictors of good outcome in the EVT group. Results: Figure 1 shows participating centers, 522 patients (288 EVT and 234 MM) were identified. Table (1) shows baseline characteristics. MM treated patients were older and had higher IV tPA treatment rates, otherwise the 2 groups were balanced. 62.7 % EVT patients had mRS 0-2 at 90 days compared to 35.4 % MM (figure 2). EVT patients had 3 times the odds of good outcome as compared to MM patients (OR: 3.1, 95% CI:2.1-4.4, P <0.001) even after adjustment for age, NIHSS, ASPECTS, IV tPA and LKN to door time (OR: 3.2, 95%CI: 2-5.2, P<0.001). sICH rate was 5.6 %, which was not statistically different than the MM group (table 1, P=0.1). Age, NIHSS, good ASPECTS, LKN to reperfusion time and successful reperfusion mTICI ≥ 2b were independent predictors of good outcome in EVT patients. There was a linear relationship between good outcome and time LKN to reperfusion (Figure 3). Conclusion: Despite inherent limitations of its retrospective design, our study suggests that EVT may be effective and safe for distal LVO (M2) relative to best MM. A trial randomizing M2 occlusions to EVT vs. MM is warranted to confirm these findings.

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

Introduction: Hypothermia may be neuroprotective in acute ischemic stroke. Stroke patients with anterior circulation large vessel occlusion (acLVO) who receive endovascular therapy (EVT) are frequently hypothermic after the procedure. We sought to analyze whether this unintended hypothermia was associated with improved functional outcome. Methods: We extracted data of consecutive patients (01/2016-04/2019) from our prospective EVT database that includes all patients screened for EVT at our center. We included patients with acLVO who received EVT and analyzed recanalization (mTICI 2b-3) and complications (i.e., pneumonia, bradyarrhythmia, venous thromboembolism) during the hospital course. We assessed functional outcome at 3 months and analyzed risk ratios (RR) for good outcome (mRS scores 0-2) and mortality of patients who were hypothermic (<36°C) compared to patients who were normothermic ( > 36°C) after EVT. We compared the frequency of complications and calculated RRs for good outcome and mortality in the subgroup with recanalization. Results: Among 674 patients with anterior circulation ischemic stroke, 372 patients received EVT for acLVO (178 [47%] male, age 77 years [65-82], NIHSS score 16 [12 - 20]). Of these, 186 patients (50%) were hypothermic (median [IQR] temperature 35.2°C [34.7-35.6]) and 186 patients were normothermic (media temperature 36.4 [36.2-36.8]) after EVT. At 3 months, 54 of 186 (29.0%) hypothermic patients compared with 65 of 186 (35.0%) normothermic patients had a good outcome (RR, 0.83; 95%CI 0.62-1.12) and 52 of 186 (27.9%) hypothermic patients compared with 46 of 186 (24.7%) normothermic patients had died (RR, 1.13; 95%CI 0.8-1.59). This relation was consistent in 307 patients (82.5% of all EVTs) with successful recanalization (good outcome: RR, 0.85; 95%CI 0.63-1.14.; mortality: RR, 1.05; 95%CI 0.7-1.57). More hypothermic patients suffered pneumonia (37.8% vs. 24.7%; p=0.003) or bradyarrhythmia (55.6% vs. 18.3%; p<0.001). Venous thromboembolism was distributed similarly (5.4% vs. 6.5%; p=0.42). Conclusion: Unintended hypothermia following EVT for acLVO was not associated with improved functional outcome or reduced mortality but an increased complication rate in patients with acute ischemic stroke.

Background Mechanical thrombectomy has become the standard care for acute ischemic stroke caused by large vessel occlusion. However, complete reperfusion cannot be achieved in all cases, and several factors influencing the results of mechanical thrombectomy have been investigated. Among others, a tortuous anatomy is associated with lower rates of complete reperfusion. We aimed to investigate whether an early division of the middle cerebral artery has an impact on reperfusion results in mechanical thrombectomy. Methods Retrospective review of consecutive patients with M1 occlusion treated endovascularly between January 2016 and December 2019 at three tertiary care centers. The study group was dichotomized based on the length of the M1 segment. Early division of the middle cerebral artery was defined as a maximum length of 10 mm of the M1 segment. Primary endpoints were first-pass mTICI scores of 3, ≥2c, and ≥2b. Secondary endpoints contained final reperfusion, number of device-passes, time interval from groin puncture to reperfusion, rate of postinterventional symptomatic intracranial hemorrhage, and frequency of emboli of new territory. Results Among 284 included patients, 70 presented with an early division of the M1 segment (25%). Reperfusion results did not differ significantly between early and late division of M1. A higher rate of symptomatic intracranial hemorrhage was found in the group with an early M1 division treated with aspiration only (14.3% vs. 0%; p = 0.013). Patients with late M1 division had a significantly higher rate of large artery sclerosis (19.2% vs. 8.6%, p = 0.039). Conclusion The anatomic variant of an early division of the middle cerebral artery was not a predictor for incomplete reperfusion.

BackgroundTime to reperfusion is an essential factor in determination of outcomes in acute ischemic stroke (AIS).ObjectiveTo establish the effect of the procedural time on the clinical outcomes of patients with AIS.MethodsData from all consecutive patients who underwent mechanical thrombectomy between September 2010 and July 2012 were analysed retrospectively. The variable of interest was procedural time (defined as time from groin puncture to final recanalization time). Outcome measures included the rates of symptomatic intracranial hemorrhage (sICH, defined as any parenchymal hematoma—eg, PH-1/PH-2), final infarct volume, 90-day mortality, and independent functional outcomes (modified Rankin Scale 0–2) at 90 days.ResultsThe cohort included 242 patients with a mean age of 65.5±14.2 and median baseline National Institutes of Health Stroke Scale score 20. 51% of the patients were female. The mean procedure time was significantly shorter in patients with a good outcome (86.7 vs 73.1 min, respectively, p=0.0228). Patients with SICH had significantly higher mean procedure time than patients without SICH (79.67 vs 104.5 min, respectively; p=0.0319), which remained significant when controlling for the previous factors (OR=0.974, 95% CI 0.957 to 0.991). No correlation was found between the volume of infarction and the procedure time (r=0.10996, p=0.0984). No association was seen between procedure time and 90-day mortality (77.8 vs 88.2 min in survivals vs deaths, respectively; p=0.0958).ConclusionsOur data support an association between the risk of SICH and a longer procedure time, but no association between procedural times and the final infarction volume or long-term functional outcomes was found.
