Introduction: An overwhelming benefit from endovascular treatment (EVT) of acute ischemic stroke (AIS) has been shown in recent trials, making it the new evidence-based standard of care for ischemic stroke due to anterior circulation large vessel occlusion. We sought to determine usage, safety and efficacy of EVT in patients ≥80 years of age. Methods: Using GWTG stroke registry data from MGH and UAMS, we analyzed 7,505 consecutive stroke admissions from 01/2009 - 06/2016. Univariate analysis was carried out to compare AIS patients < 80 vs. those ≥ 80yr. Results: Of the total 7,505 AIS patients, 3,722 presented within 12 hr of last known well and of these 334 (334/3722, 9%) underwent EVT. The majority of AIS patients undergoing EVT were younger than 80yr of age (264/334, 79%). Of the patients who underwent EVT, younger patients were more often male, Caucasian, and had stroke risk factors of atrial fibrillation, CAD, hypertension and smokers. The two groups were similar in NIHSS, initial clinical presentation, modified pre-stroke Rankin scale of ≤ 3, and initiation of tPA as a drip and ship or stroke center front-door administration. Higher rates of pneumonia were observed in younger patients while rates of sICH were similar. Younger patients were more often discharged to home/inpatient rehabilitation facility. On univariate analysis, in-hospital mortality was significantly higher in patients ≥ 80yr [Unadj. OR 2.50 (1.24, 5.03), p=0.01], however the strength of the association attenuated substantially after adjusting for significant covariates [Adj. OR 2.34 (0.99, 5.47), p=0.05] (Table). Conclusion: Elderly stroke patients are largely excluded from clinical trials and data are limited on the effectiveness of EVT in this cohort. Our results showed that rate of sICH and adjusted in-hospital mortality was not statistically different between those < 80yr vs. ≥ 80yr. Further studies are needed to explore the functional outcome of the elderly stroke patients undergoing EVT.

AbstractEndovascular treatment (EVT) has been accepted as the standard of care for patients with acute ischemic stroke. The aim of the present study was to compare clinical outcomes of patients who received EVT within and beyond 6 h from symptom onset to groin puncture without perfusion software in Guangdong district, China. Between March 2017 and May 2018, acute ischemic stroke patients who received EVT from 6 comprehensive stroke centers, were enrolled into the registry study. In this subgroup study, we included all patients who had acute proximal large vessel occlusion in the anterior circulation. The demographic, clinical and neuroimaging data were collected from each center. A total of 192 patients were included in this subgroup study. They were divided into two groups: group A (n = 125), within 6 h; group B (n = 67), 6–24 h from symptom onset to groin puncture. There were no substantial differences between these two groups in terms of 90 days favorable outcome (modified Rankin scale [mRS] ≤ 2, P = 0.051) and mortality (P = 0.083), and the risk of symptomatic intracranial hemorrhage at 24 h (P = 0.425). The NIHSS (median 16, IQR12-20, group A; median 12, IQR8-18, group B; P = 0.009) and ASPECTS (median 10, IQR8-10, group A; median 9, IQR8-10, group B; P = 0.034) at baseline were higher in group A. The anesthesia method (general anesthesia, 21.3%, group A vs. 1.5% group B, P = 0.001) were also statistically different between the two groups. The NIHSS and ASPECTS were higher, and general anesthesia was also more widely used in group A. Clinical outcomes were not significantly different within 6 h versus 6–24 h from symptom onset to groin puncture in this real world study.

BackgroundParenchymal hemorrhage (PH) is a troublesome complication after endovascular treatment (EVT).ObjectiveTo investigate the incidence, independent predictors, and clinical impact of PH after EVT in patients with acute ischemic stroke (AIS) due to anterior circulation large vessel occlusion (LVO).MethodsSubjects were selected from the ANGEL-ACT Registry. PH was diagnosed according to the European Collaborative Acute Stroke Study classification. Logistic regression analyses were performed to determine the independent predictors of PH, as well as the association between PH and 90-day functional outcome assessed by modified Rankin Scale (mRS) score.ResultsOf the 1227 enrolled patients, 147 (12.0%) were diagnosed with PH within 12–36 hours after EVT. On multivariable analysis, low admission Alberta Stroke Program Early CT score (ASPECTS)(adjusted OR (aOR)=1.13, 95% CI 1.02 to 1.26, p=0.020), serum glucose >7 mmol/L (aOR=1.82, 95% CI 1.16 to 2.84, p=0.009), and neutrophil-to-lymphocyte ratio (NLR; aOR=1.05, 95% CI 1.02 to 1.09, p=0.005) were associated with a high risk of PH, while underlying intracranial atherosclerotic stenosis (ICAS; aOR=0.42, 95% CI 0.22 to 0.81, p=0.009) and intracranial angioplasty/stenting (aOR=0.37, 95% CI 0.15 to 0.93, p=0.035) were associated with a low risk of PH. Furthermore, patients with PH were associated with a shift towards to worse functional outcome (mRS score 4 vs 3, adjusted common OR (acOR)=2.27, 95% CI 1.53 to 3.38, p<0.001).ConclusionsIn Chinese patients with AIS caused by anterior circulation LVO, the risk of PH was positively associated with low admission ASPECTS, serum glucose >7 mmol/L, and NLR, but negatively related to underlying ICAS and intracranial angioplasty/stenting.Trial registration numberNCT03370939.

Background and Purpose— Endovascular treatment (EVT) of patients with acute ischemic stroke because of large vessel occlusion involves complicated logistics, which may cause a delay in treatment initiation during off-hours. This might lead to a worse functional outcome. We compared workflow intervals between endovascular treatment–treated patients presenting during off- and on-hours. Methods— We retrospectively analyzed data from the MR CLEAN Registry, a prospective, multicenter, observational study in the Netherlands and included patients with an anterior circulation large vessel occlusion who presented between March 2014 and June 2016. Off-hours were defined as presentation on Monday to Friday between 17:00 and 08:00 hours, weekends (Friday 17:00 to Monday 8:00) and national holidays. Primary end point was first door to groin time. Secondary end points were functional outcome at 90 days (modified Rankin Scale) and workflow time intervals. We stratified for transfer status, adjusted for prognostic factors, and used linear and ordinal regression models. Results— We included 1488 patients of which 936 (62.9%) presented during off-hours. Median first door to groin time was 140 minutes (95% CI, 110–182) during off-hours and 121 minutes (95% CI, 85–157) during on-hours. Adjusted first door to groin time was 14.6 minutes (95% CI, 9.3–20.0) longer during off-hours. Door to needle times for intravenous therapy were slightly longer (3.5 minutes, 95% CI, 0.7–6.3) during off-hours. Groin puncture to reperfusion times did not differ between groups. For transferred patients, the delay within the intervention center was 5.0 minutes (95% CI, 0.5–9.6) longer. There was no significant difference in functional outcome between patients presenting during off- and on-hours (adjusted odds ratio, 0.92; 95% CI, 0.74–1.14). Reperfusion rates and complication rates were similar. Conclusions— Presentation during off-hours is associated with a slight delay in start of endovascular treatment in patients with acute ischemic stroke. This treatment delay did not translate into worse functional outcome or increased complication rates.

ObjectiveTo determine the impact of endovascular therapy for large vessel occlusion stroke in patients with pre-morbid disability versus those without.MethodsWe performed a post-hoc analysis of the TREVO Stent-Retriever Acute Stroke (TRACK) Registry, which collected data on 634 consecutive stroke patients treated with the Trevo device as first-line EVT at 23 centers in the United States. We included patients with internal carotid or middle cerebral (M1/M2 segment) artery occlusions and the study exposure was patient- or caregiver-reported premorbid modified Rank Scale (mRS) ≥2 (premorbid disability, PD) versus premorbid mRS score 0-1 (no premorbid disability, NPD). The primary outcome was no accumulated disability, defined as no increase in 90-day mRS from the patient’s pre-morbid mRS.ResultsOf the 634 patients in TRACK, 407 patients were included in our cohort, of which 53/407 (13.0%) had PD. The primary outcome of no accumulated disability was achieved in 37.7% (20/53) of patients with PD and 16.7% (59/354) of patients with NPD (p<0.001), while death occurred in 39.6% (21/53) and 14.1% (50/354) (p<0.001), respectively. The adjusted odds ratio of no accumulated disability for PD patients was 5.2 (95% CI 2.4-11.4, p<0.001) compared to patients with NPD. However, the adjusted odds ratio for death in PD patients was 2.90 (95% CI 1.38-6.09, p=0.005).ConclusionsIn this study of anterior circulation acute ischemic stroke patients treated with EVT, we found that premorbid disability was associated with a higher probability of not accumulating further disability compared to patients with no premorbid disability, but also with higher probability of death.Classification of EvidenceThis study provides Class II evidence that in anterior circulation acute ischemic stroke treated with EVT, patients with premorbid disability compared to those without disability were more likely not to accumulate more disability but were more likely to die.

Background: A 2013 consensus statement recommended the use of the modified Treatment In Cerebral Ischemia (mTICI) scale to evaluate angiographic revascularization after endovascular treatment (EVT) of acute ischemic stroke due to its higher inter-rater agreement and capacity of clinical outcome prediction. The current definition of successful revascularization includes the achievement of grades mTICI 2b or 3. However, mTICI 2b grade encompasses a large heterogeneity of revascularization states, and prior studies suggested that the magnitude of benefit derived from mTICI 2b and mTICI 3 does not seem to be equivalent. In a way to restrain the referred heterogeneity, Goyal et al. [J Neurointerv Surg 2014; 6: 83–86] proposed a revised mTICI scale that includes a 2c grade (rTICI). Methods: Retrospective analysis of prospectively collected data from consecutive cases of EVT for anterior circulation large-vessel occlusion, performed between January 2015 and July 2017. Patients with mTICI 2b or 3 grades were reclassified according to the rTICI scale, and the outcomes between the 3 revascularization grades (rTICI 2b, 2c, 3) compared. Results: Our study population of 226 patients (64 rTICI 2b, 30 rTICI 2c, 132 rTICI 3) has a mean age of 71 years, 48.2% males, median baseline NIHSS of 16 (13–19) and ASPECTS of 8 (7–9). The 3 revascularization grades are represented by homogeneous populations. Logistic regression analysis showed statistically significant higher rates of functional independence at 3 months (65.9 vs. 50.0%; adjusted OR 0.39, 95% CI 0.18–0.86), with lower rates of mortality (8.3 vs. 15.6%; adjusted OR 3.54, 95% CI 1.14–10.97) and intracranial hemorrhage (ICH) in rTICI 3 than 2b groups. When comparing rTICI 3 with 2c groups, there were only statistically significant differences in the total ICH rate (8.3 vs. 26.7%; adjusted OR 7.08, 95% CI 1.80–27.82) but not in symptomatic ICH. Conclusions: These results corroborate the scarce prior findings suggesting that patients with rTICI 2c grade should be reported separately, since they have similar outcomes to rTICI 3, and better than rTICI 2b patients. Therefore, we suggest resetting the angiographic revascularization endpoint to perfect revascularization (rTICI 2c or 3 grades), a target that neurointerventionalists should strive to achieve.

Abstract Background Acute ischemic stroke (AIS) leads to a substantial burden of disease among the elderly. There may be a delay in or a poor outcome of endovascular treatment (EVT) among AIS patients with large-vessel occlusion (LVO) during off-hours. By using a prospective, nationwide registry, we compared the workflow intervals and radiological/clinical outcomes between patients with acute LVO treated with EVT presenting during off- and on-hours. Methods We analyzed prospectively collected Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke (ANGEL-ACT) data. Patients presenting during off-hours were defined as those presenting to the emergency department from Monday to Friday between the hours of 17:30 and 08:00, on weekends (from 17:30 on Friday to 08:00 on Monday), and on national holidays. We used logistic regression models with adjustment for potential confounders to determine independent associations between the time of presentation and outcomes. Results Among 1788 patients, 1079 (60.3%) presented during off-hours. The median onset-to-door time and onset-to-reperfusion time were significantly longer during off-hours than on-hours (165 vs 125 minutes, P=0.002 and 410 vs 392 minutes, P=0.027). However, there were no significant differences between patients presenting during off- and on-hours in any radiological/clinical outcomes (mRS score: 3 vs 3 points, P=0.204; mortality: 15.9% vs 14.3%, P=0.172; successful reperfusion: 88.5% vs 87.2%, P=0.579; sICH: 7.2% vs 8.4%, P=0.492). Conclusions Off-hours presentation in the nationwide real-world registry was associated with a delay in the visit and reperfusion time of EVT in patients with AIS. However, this delay did not lead to worse radiological/clinical outcomes.
