    Abstract: Sex disparities in acute large vessel occlusion (LVO) following endovascular treatment (EVT) have been recently reported. However, there is uncertainty about the effect of sex differences on functional outcomes after EVT, particularly in an Asian population. The present study aimed to compare the clinical and safety outcomes between men and women with anterior circulation LVO treated with EVT. Methods: We analyzed data from the ANGEL-ACT (Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke: a Prospective Multicenter Registry Study) Registry, which was conducted at 111 hospitals from 26 provinces in China between November 2017 and March 2019. Men and women with anterior circulation LVO treated with EVT were matched using propensity scores. After a 1:1 propensity score matching, we compared the clinical outcomes including 90-day ordinal modified Rankin Scale distribution (primary outcome), procedure duration, successful reperfusion, symptomatic intracranial hemorrhage, and mortality. Furthermore, we explored sex modification on the primary outcome in subgroup analysis. Results: Of 1321 patients, 483 (36.6%) were women and 838 (63.4%) were men. The mean age for women and men were 68 and 62 years old, respectively. Among 578 patients identified after matching, there were no sex differences (men versus women) in 90-day ordinal modified Rankin Scale distribution (median [interquartile range], 4 [1–5] versus 3 [1–5], P =0.464), successful reperfusion (86.5% versus 91.0%, P =0.089), symptomatic intracranial hemorrhage (6.5% versus 7.9%, P =0.512), and mortality within 90 days (17.7% versus 17.0%, P =0.826). However, men had a longer median procedure duration than women (86 [52–128] versus 72 [48–110] minutes, β=14.51, [95% CI, 4.19–24.84]; P =0.006). Subgroup analysis showed that in patients with National Institutes of Health Stroke Scale score 〈 15, women tended to have a better outcome than men, whereas there was no gender effect in those with National Institutes of Health Stroke Scale score ≥15 ( P for interaction=0.032). Conclusions: Overall, this matched-control study from the ANGEL-ACT study showed similar clinical outcomes between men and women with anterior circulation LVO treated with EVT. However, in the subgroup of patients presenting with lower stroke severity (ie, National Institutes of Health Stroke Scale score 〈 15), women tended to have a better outcome than men highlighting a potential sex disparity for further investigation.

    Abstract: Early neurological deterioration (END) may occur in some patients with acute large vessel occlusion (LVO) undergoing endovascular treatment (EVT). Despite several clear causes of END, such as symptomatic intracranial hemorrhage, failure of recanalization, and intraprocedure complications, a particular END, termed unexplained END (END unexplained ), exists. We aimed to investigate the incidence, independent predictors, and clinical impact of END unexplained after EVT in patients with acute LVO. Methods Subjects were selected from the ANGEL-ACT registry. END unexplained was defined as ≥4-point increase in the National Institutes of Health Stroke Scale (NIHSS) score between baseline and 24 hours after EVT, without the causes listed above. Logistic regression analyses were performed to determine the independent predictors of END unexplained , as well as the association between END unexplained and 90-day outcomes assessed by modified Rankin Scale (mRS) score. Results Among the 1557 enrolled patients, the incidence of END unexplained was 4.3% (67/1557). Admission NIHSS ≤8 (OR=6.88, 95% CI 3.86 to 12.26, p 〈 0.001), general anesthesia (OR=3.15, 95% CI 1.81 to 5.48, p 〈 0.001), admission neutrophil to lymphocyte ratio 〉 5 (OR=2.82, 95% CI 1.61 to 4.94, p 〈 0.001), and number of EVT attempts 〉 3 (OR=2.11, 95% CI 1.14 to 3.89, p=0.018) were associated independently with a high risk of END unexplained . Furthermore, patients with END unexplained were associated with a shift toward worse 90-day outcomes (mRS 5 vs 3, common OR=5.24, 95% CI 3.22 to 8.52, p 〈 0.001). Conclusions END unexplained associated with poor 90day outcomes occurred in 4.3% of patients with acute LVO undergoing EVT. Several independent predictors of END unexplained were identified in this study, which should be considered in daily practice to improve acute LVO management.

    Abstract: Intracranial atherosclerotic disease (ICAD) is a common etiology of acute vertebrobasilar artery occlusion (VBAO) in Asia, which complicated endovascular treatment (EVT). We aimed to investigate the incidence, impacts, and predictors of ICAD in VBAO. Methods: Subjects were selected from the Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke registry and divided into two groups based on whether underlying ICAD existed. Underlying ICAD was determined when the following situations arise in the occlusion site during EVT: (1) fixed stenosis degree 〉 70% or (2) stenosis 〉 50% with distal blood flow impairment or evidence of repeated reocclusion. Multivariable regression models were used to investigate the effect of underlying ICAD on outcomes measured by modified Rankin Scale (mRS) score at 90 days and to identify baseline characteristics associated with underlying ICAD. Results: Among the 315 patients enrolled, 171 (54.3%) had underlying ICAD. Favorable functional outcomes (mRS 0–3) occurred in 79 of 163 patients (48.5%) with ICAD and 69 of 137 patients (50.4%) without ICAD ( p = 0.743). Outcomes were similar between the two groups and remained similar after adjusting for the confounders. History of hypertension and elevated admission neutrophil to lymphocyte ratio were strong predictors of underlying ICAD, whereas history of atrial fibrillation and distal basilar artery occlusion were negative predictors. Conclusions: In our study, underlying ICAD was recognized in approximately half of the VBAO patients, leading to comparable outcomes after more complex EVT strategies. Some baseline characteristics were identified to be predictors for underlying ICAD, which were helpful to guide the EVT strategies before the procedure.

    Abstract: Parenchymal hemorrhage (PH) is a troublesome complication after endovascular treatment (EVT). Objective To 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). Methods Subjects 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. Results Of 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). Conclusions In 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.

    Abstract: The superiority of balloon angioplasty plus aggressive medical management (AMM) to AMM alone for symptomatic intracranial artery stenosis (sICAS) on efficacy and safety profiles still lacks evidence from randomised controlled trials (RCTs). Aim To demonstrate the design of an RCT on balloon angioplasty plus AMM for sICAS. Design Balloon Angioplasty for Symptomatic Intracranial Artery Stenosis (BASIS) trial is a multicentre, prospective, randomised, open-label, blinded end-point trial to investigate whether balloon angioplasty plus AMM could improve clinical outcome compared with AMM alone in patients with sICAS. Patients eligible in BASIS were 35–80 years old, with a recent transient ischaemic attack within the past 90 days or ischaemic stroke between 14 days and 90 days prior to enrolment due to severe atherosclerotic stenosis (70%–99%) of a major intracranial artery. The eligible patients were randomly assigned to receive balloon angioplasty plus AMM or AMM alone at a 1:1 ratio. Both groups will receive identical AMM, including standard dual antiplatelet therapy for 90 days followed by long-term single antiplatelet therapy, intensive risk factor management and life-style modification. All participants will be followed up for 3 years. Study outcomes Stroke or death in the next 30 days after enrolment or after balloon angioplasty procedure of the qualifying lesion during follow-up, or any ischaemic stroke or revascularisation from the qualifying artery after 30 days but before 12 months of enrolment, is the primary outcome. Discussion BASIS trail is the first RCT to compare the efficacy and safety of balloon angioplasty plus AMM to AMM alone in sICAS patients, which may provide an alternative perspective for treating sICAS.

    Abstract: To investigate the safety and efficacy of endovascular treatment (EVT) for acute medium vessel occlusion (MeVO) in the anterior circulation and to explore the independent predictors of the 90-day good outcome for such patients. Methods Data from ANGEL-ACT Registry were analysed in our study. The outcomes, such as the modified Rankin Scale (mRS) at 90 days, successful recanalisation rate and symptomatic intracranial haemorrhage (SICH) rate, were compared between MeVO and acute large vessel occlusions (LVO). Then, the independent predictors of the good outcome at 90 days in MeVO patients were determined by the logistic regression analyses. Results We included 1032 subjects in the analysis, of which, 147 were MeVO and 885 were LVO. mRS at 90 days distribution (3 (0–4) vs 3 (0–5), common odds ratio (OR) =1.00, 95% confidence interval (CI) 0.73 to 1.38, p=0.994), SICH rate (4.8% vs 8.9%; OR=0.59, 95% CI 0.26 to 1.34, p=0.205) and successful recanalisation rate (89.8% vs 89.7%; OR=1.00 95% CI 0.51 to 1.93, p=0.992) were similar between the MeVO and LVO groups after adjusting for the confounders. We identified that baseline neutrophil-to-lymphocyte ratio ≤4.1 (OR=2.13, 95% CI 1.14 to 3.99, p=0.019), baseline National Institutes of Health Stroke Scale ≤14 (OR=1.96, 95% CI 1.02 to 3.80, p=0.045) and mechanical thrombectomy passes ≤1 (OR=2.16, 95% CI 1.14 to 4.11, p=0.021) were independent predictors of the 90-day good outcome in MeVO patients undergoing EVT. Conclusions Patients with MeVO achieved similar 90-day mRS, SICH rate and successful recanalisation rate after EVT compared with patients with LVO. Several independent predictors of 90-day good outcome in MeVO patients undergoing EVT were determined, which should be highly considered in MeVO stroke management.

    Abstract: To investigate the performance of the Critical Area Perfusion Score (CAPS), based on computed tomography perfusion (CTP) time to maximum (Tmax) 〉 10s maps, to predict the outcome in acute basilar artery occlusion (BAO) in patients undergoing endovascular treatment (EVT). Methods We perform a retrospective analysis of a prospectively collected database of acute BAO treated with EVT in a comprehensive stroke center. The favorable outcome was defined as the 90-day modified Rankin Scale (mRS) ≤ 3. We performed the logistic regression analysis to find the independent predictors of the favorable outcome. Then, we used receiver operating characteristic analyses to assess the predictive value of the imaging parameters, including CAPS, Posterior Circulation Alberta Stroke Program Early CT Score (PC-ASPECTS), pons midbrain index (PMI), posterior circulation computed tomography angiography (PC-CTA) score, Basilar Artery on Computed Tomography Angiography (BATMAN) score, and CTP parameters. Finally, the Delong test was used to compare the area under the curve (AUC) of CAPS against the other imaging parameters. Results Of the 65 enrolled patients, the incidence of the favorable outcome was 44.6% (29/65). Low CAPS (per 1- point increased odds ratio [OR], 0.43; 95% confidence interval [CI] , 0.22–0.86; P = 0.017) and admission National Institutes of Health Stroke Scale (NIHSS) (per 1- point increased OR, 0.80; 95% CI, 0.70–0.91; P = 0.001) were independently associated with favorable outcome. The AUC of CAPS was 0.83 (95% CI, 0.74–0.93; P 〈 0.001) with ≤ 3 cut-off value, 89.66% sensitivity, 77.22% specificity, and 80.00% accuracy, which was greater than the other imaging parameters (All P for Delong test 〈 0.05). Conclusions CAPS was the most accurate imaging-based outcome predictor in acute BAO patients. Future large prospective multicenter studies are needed to verify these results.

    Abstract: To explore the incidence, predictors, and association of first pass effect (FPE) on clinical outcomes of mechanical thrombectomy (MT) for acute vertebrobasilar artery occlusion (VBAO) in the Asian population. Methods We selected patients from the ANGEL-ACT registry. We defined FPE as complete recanalization after one MT attempt without rescue treatment, multiple pass effect (MPE) as complete recanalization after 〉 1 MT attempt or after one MT attempt with rescue treatment, and incomplete recanalization (ICR) as a modified Thrombolysis in Cerebral Ischemia score of 2b, independent of the number of MT attempts. We conducted multivariable logistic analyses to identify the independent predictors of FPE and to compare the outcomes, including favorable outcome, mortality within 90 days, and intracranial hemorrhage (ICH) among the FPE, MPE, and ICR groups. Results Two hundred and seventy-nine patients, 68 with FPE (24.4%), 114 with MPE (40.9%), and 83 with ICR (29.7%), were included. Underlying intracranial atherosclerosis disease (ICAD) (adjusted OR (aOR) 0.16, 95% CI 0.08 to 0.34, P 〈 0.001) was independently associated with a low chance of FPE. Furthermore, FPE was associated with a favorable outcome compared with MPE and ICR (MPE vs FPE, aOR 0.49, 95% CI 0.25 to 0.97, P=0.040; ICR vs FPE, aOR 0.38, 95% CI 0.18 to 0.81, P=0.012), and decreased mortality (MPE vs FPE, aOR 2.57, 95% CI 1.04 to 6.36, P=0.041) compared with MPE but similar mortality to ICR (P=0.374). No difference was found for ICH among the three groups (P 〉 0.05). Conclusions FPE occurred in 24.4% of patients with VBAO in our cohort, which was associated with improved clinical outcomes compared with MPE and ICR. VBAO with underlying ICAD was less likely to achieve FPE. Trial registration number NCT03370939 .

    Abstract: The efficacy and safety of mechanical thrombectomy (MT) in acute large vessel occlusion (LVO) patients with minor stroke (NIHSS ≤ 5) remains undetermined. We aimed to compare the efficacy and safety of intra-arterial thrombolysis (IAT) alone vs. MT for LVO patients with minor stroke. Methods Patients were selected from the Acute Ischemic Stroke Cooperation Group of Endovascular Treatment (ANGEL) registry, a prospective multicenter registry study, and divided into MT and IAT alone groups. We compared the outcome measures between the two groups, including 90-day functional outcome evaluated by the modified Rankin Scale (mRS), the final recanalization level, intracranial hemorrhage, and mortality within 90-days by logistic regression models with adjustment. Besides the conventional multivariable analysis, we performed a sensitivity analysis by adjusting the propensity score to confirm our results. The propensity score was derived using a logistic regression model. Results Of the 120 patients, 63 received IAT alone and 57 received MT as the first-line treatment strategy. As compared to MT group, patients in the IAT alone group were associated with a higher chance of 90-day mRS 0-2 [93.7% vs. 71.9%, odds ratio (OR) = 4.75, 95% confidence interval (CI): 1.20–18.80, P = 0.027], a high chance of 90-day mRS 0-3 (96.8% vs. 86.7%, OR = 11.35, 95% CI: 1.93–66.86, P = 0.007), a shorter median time from puncture to recanalization (PTR) (60 min vs. 100 min, β = −63.70, 95% CI: −81.79– −45.61, P & lt; 0.001), a lower chance of any intracranial hemorrhage (ICH) within 48 h (3.2% vs. 19.3%, OR = 0.15, 95% CI: 0.03–0.79, P = 0.025), and a lower chance of mortablity within 90 days (1.6% vs. 9.2%, OR = 0.05, 95% CI: 0.01–0.57, P = 0.016). Similarly, the sensitivity analysis showed the robustness of the primary analysis. Conclusions Compared with MT, IAT may improve 90-day clinical outcomes with decreased ICH rate and mortality in LVO patients with minor stroke.
