Favorable Clinical Outcome

Background and purposeGiven the promising performance of the new Embolus Retriever with Interlinked Cages (ERIC) in smaller case series, we sought to assess the efficacy and safety of mechanical thrombectomy (MT) with ERIC compared with other stent retrievers (SRs) in acute ischemic stroke due to large vessel occlusion (LVO).MethodsWe reviewed the databases of two comprehensive stroke centers in in Germany and Switzerland for MT due to LVO in the anterior circulation with either ERIC or another SR as a first device. Co-primary outcome was defined as successful recanalization (Thrombolysis in Cerebral Infarction 2b/3) after the first device and favorable outcome (modified Rankin Scale score 0–2) at 90 days' follow-up. Multiple logistic regression analysis was applied to adjust for potential confounders.Results183 consecutive patients with stroke were treated with either ERIC (49%) or a SR (51%) as the first device and successful recanalization was seen in 82% and 57%, respectively (P<0.001). Adding SR to futile ERIC recanalization or vice versa increased final recanalization rates (ERIC: 87%, SR: 79%). The use of ERIC as a first device resulted in favorable clinical outcome in 50% compared with 35% when a SR was used (P=0.038), an effect driven by age, stroke severity, presence of carotid-T-occlusion, and general anesthesia and not by the device deployed.ConclusionThe use of ERIC as a first device appeared to be associated with higher rates of successful recanalization and resulted in better functional outcome. However, favorable outcome was not attributable to ERIC. Most importantly, both device types complemented one another and improved final recanalization rates when used successively.

AimTo explore the predictors of infarct core expansion despite full reperfusion after intra-arterial therapy (IAT).MethodsWe retrospectively reviewed 604 consecutive patients who underwent IAT for anterior circulation large vessel occlusion acute ischemic stroke in two tertiary centers (2008–2013/2010–2013). Sixty patients selected by MRI or CT perfusion presenting within <24 h of onset with modified Thrombolysis In Cerebral Infarction (mTICI) grade 3 or 2c reperfusion were included. Significant infarct growth (SIG) was defined as infarct expansion >11.6 mL.ResultsMean age was 67.0±13.7 years, 56% were men. Mean National Institute of Health Stroke Scale (NIHSS) score was 16.2±6.1, time from onset to puncture was 6.8±3.1 h, and procedure length was 1.3±0.6 h. MRI was used for baseline core analysis in 43% of patients. Mean baseline infarct volume was 17.1±19.1 mL, absolute infarct growth was 30.6±74.5 mL, and final infarct volume was 47.7±77.7 mL. Overall, 35% of patients had SIG. Three of 21 patients (14%) treated with stent-retrievers had SIG compared with 14 of 39 (36%) with first-generation devices. Eight of 21 patients (38%) with intravenous tissue plasminogen activator (IV t-PA) had infarct growth compared with 25/39 (64%) without. 23% of patients with SIG had a modified Rankin Scale score ≤2 at 3 months compared with 48% of those without SIG. Multivariate logistic regression indicated that race affected infarct growth. Use of IV t-PA (p=0.03) and stent-retrievers (p=0.03) were independently and inversely correlated with SIG.ConclusionsDespite full reperfusion, infarct growth is relatively frequent and may explain poor clinical outcomes in this setting. Ethnicity was found to influence SIG. Use of IV t-PA and stent-retrievers were associated with less infarct core expansion.

ABSTRACT Background: Intravenous thrombolysis (IVT) has now become a standard treatment in eligible patients with acute ischemic stroke (AIS) who present within 4.5 h of symptom onset. Objective: To determine the usefulness of IVT and the subset of patients who will benefit from IVT in AIS within 4.5 h. Materials and Methods: Patients with AIS within 4.5 h of symptom onset who underwent IVT were studied prospectively. The study period was from October 2011 to October 2015. Results: A total of 97 patients were thrombolysed intravenously. The mean onset to needle time in all patients was 177.2 ± 62 min (range: 60–360). At 3 months follow-up, favorable outcome was seen in 65 patients (67.1%) and poor outcome including death in the remaining 32 patients (32.9%). Factors predicting favorable outcome was age <65 years (P = 0.02), the National Institute of Health Stroke Scale (NIHSS) <15 (P < 0.001), small vessel occlusion (P = 0.006), cardioembolism (P = 0.006), and random blood sugar (RBS) <250 mg/dl (P < 0.001). Factors predicting poor outcome was diabetes mellitus (P = 0.01), dyslipidemia (P = 0.01), NIHSS at admission >15 (P = 0.03), RBS >250 mg/dl (P = 0.01), Dense cerebral artery sign, age, glucose level on admission, onset-to-treatment time, NIHSS on admission score >5 (P = 0.03), and occlusion of large artery (P = 0.02). Conclusion: Milder baseline stroke severity, blood glucose <250 mg/dL, younger patients (<65 years), cardioembolic stroke, and small vessel occlusion benefit from recombinant tissue plasminogen activator.

IntroductionOver the past decade, endovascular techniques for the treatment of acute ischemic stroke have emerged significantly. However, revascularization rates are limited at approximately 80%, and mechanical thrombectomy procedures still last about 1 h. Therefore, we investigated the novel direct aspiration first pass technique for its efficacy and safety.MethodsOur neurointerventional database was screened for patients who received mechanical thrombectomy for acute ischemic stroke using the Penumbra 5MAX ACE aspiration catheter on an intention to treat basis between November 2013 and June 2014. Procedural data, including modified Thrombolysis in Cerebral Infarction (mTICI) score, procedural timings, and complications, as well as clinical data at admission and discharge, were analyzed.Results54 patients received mechanical thrombectomy using the 5MAX ACE. Median age was 69 (39–94) years (54% were men). Baseline National Institutes of Health Stroke Scale (NIHSS) score was 15 (2–27) and 44/54 (81%) patients received intravenous thrombolysis. Vessel occlusion sites were 91% anterior circulation and 9% posterior circulation. A successful revascularization result (mTICI ≥2b) was achieved in 93% of cases whereas direct aspiration alone was successful in 30/54 (56%) cases; among these, median time from groin puncture to revascularization was 30 min (9–113). Symptomatic intracranial hemorrhage occurred in 2/54 (4%) patients, and embolization to new territories in 3/54 (6%). Median NIHSS at discharge was 6 (0–24); 46% of patients were independent at discharge.ConclusionsThe direct aspiration first pass technique proofed to be fast, effective, and safe. Promising revascularization results can be achieved quickly in more than 50% of patients using this technique as the firstline option. Nevertheless, stent retrievers are still warranted in approximately 40% of cases to achieve a favorable revascularization result.

OBJECTIVEMechanical thrombectomy (MT) is now the standard of care for acute ischemic stroke (AIS) secondary to large-vessel occlusion, but there remains a question of whether elderly patients benefit from this procedure to the same degree as the younger populations enrolled in the seminal trials on MT. The authors compared outcomes after MT of patients 80–89 and ≥ 90 years old with AIS to those of younger patients.METHODSThe authors retrospectively analyzed records of patients undergoing MT at their institution to examine stroke severity, comorbid conditions, medical management, recanalization results, and clinical outcomes. Univariate and multivariate logistic regression analysis were used to compare patients < 80 years, 80–89 years, and ≥ 90 years old.RESULTSAll groups had similar rates of comorbid disease and tissue plasminogen activator (tPA) administration, and stroke severity did not differ significantly between groups. Elderly patients had equivalent recanalization outcomes, with similar rates of readmission, 30-day mortality, and hospital-associated complications. These patients were more likely to have poor clinical outcome on discharge, as defined by a modified Rankin Scale (mRS) score of 3–6, but this difference was not significant when controlled for stroke severity, tPA administration, and recanalization results.CONCLUSIONSOctogenarians, nonagenarians, and centenarians with AIS have similar rates of mortality, hospital readmission, and hospital-associated complications as younger patients after MT. Elderly patients also have the capacity to achieve good functional outcome after MT, but this potential is moderated by stroke severity and success of treatment.

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.

Background: Recent endovascular stroke studies utilizing primarily stent retrievers have proven clinical benefit among eligible patients. It remains unclear if this benefit is exclusive to stent retrievers. We present the results of a single-center experience for patients undergoing primary aspiration thrombectomy for acute ischemic stroke (AIS). Methods: A retrospective analysis of all AIS patients receiving primary aspiration thrombectomy from January 2014 to March 2016 was performed. We assessed stroke severity at admission and discharge as defined by the National Institutes of Health Stroke Scale score (NIHSSS), median onset to puncture and onset to recanalization times, location of target vessel treated, rate of concurrent intravenous (IV) alteplase use, and rate of TICI 2b/3 reperfusion. Outcomes adjudicated included rates of symptomatic intracerebral hemorrhage (sICH), favorable discharge disposition to home, and 90-day modified Rankin Scale (mRS) score ≤2. Results: During the study period, 121 patients (mean age 68.7±16.5 years, 53.7% women) received primary aspiration thrombectomy for 124 occlusions (26% terminal internal carotid artery, 45% M1, 15% M2, 11% basilar artery, 3% other). Median admission NIHSSS was 19 [11, 22] and improved to 6 [1, 15] upon discharge. Median onset to puncture and onset to recanalization times were 258 [148, 371] and 300 [180, 409] minutes, respectively. The rate of TICI 2b/3 reperfusion was 84.7%, and 52% received adjunctive IV alteplase. Rates of favorable discharge to home was 28.9% and 90-day mRS ≤2 was 39.8%. Only one patient developed sICH. Conclusion: Our single-center experience shows that primary aspiration thrombectomy can yield both favorable angiographic and clinical outcomes with minimal adverse effect.

Statin Adherence

Although statins are established therapy for the secondary prevention of ischemic stroke, factors associated with adherence to statin treatment following ischemic stroke are not well known. To address this, we assessed the 6-month statin adherence using 8-item Morisky Medication Adherence Scale-8 in patients with acute ischemic stroke. Of 991 patients, 65.6% were adherent to statin at 6-month after discharge. Multiple logistic regression analysis showed that patients’ awareness of hyperlipidemia (OR 1.62; 95% CI 1.07–2.43), large artery stroke subtype (versus non-large artery stroke, OR 1.79; 95% CI 1.19–2.68), and alcohol drinking habits (OR 1.64; 95% CI 1.06–2.53) were positively associated, while high statin dose (versus low dose, OR 0.6; 95% CI 0.40–0.90) and higher daily number of medication pills (OR 0.93; 95% CI 0.88–0.97) were found to have a negative association with self-reported good adherence to statin medication after acute ischemic stroke. However, stroke severity and diagnosis of hyperlipidemia were not associated with adherence. These results suggest that educational and motivational interventions may enhance statin adherence because modifiable factors were associated with statin adherence.

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: There is very limited data on the use of advanced neuroimaging to select patients with acute ischemic stroke and large vessel occlusion for intraarterial therapy beyond 6 hours from onset. Our aim is to report the outcome of patients with acute ischemic stroke and large artery occlusion who presented beyond 6 hours from onset, had favorable MRI imaging profile, and underwent mechanical embolectomy. Methods: This is a single institution retrospective study between December 1st, 2015, and July 30 th , 2016 with acute ischemic stroke and anterior circulation large vessel occlusion (LVO) with ASPECTS of 6 or more and beyond 6 hours from symptoms onset. Favorable imaging profile was defined as 1) DWI lesion volume (as defined as apparent diffusion coefficient < 620 X 10-6 mm2/s) of 70 mL or less AND 2) Penumbra volume (as defined by volume of tissue with Tmax >6 sec) of 15 mL or greater AND 3) A mismatch ratio of 1.8 or more AND 4) Volume of tissue with perfusion lesion with Tmax > 10 sec is less than 100 mL. Good outcome was defined as a 90 day mRS≤2. Results: In the study period, 41 patients met the inclusion criteria; 22 (53.6%) had favorable imaging profile and underwent mechanical embolectomy. The median age was 75 years (59-92), 68.2% were females; the median time from last known normal to groin puncture was 684.5 minutes (range 363-1628) and the median admission NIHSS score was 17.5 (range 4-28). The rate of good outcomes in this series was similar to that in a patient level pooled meta-analysis of the recent endovascular trials (68.2% vs. 46.0%, p=0.07). The rate of good outcome matches that of the EXTEND-IA trial that selected patients using perfusion imaging (68.2% vs. 71.0%, p = 1.00). None of the patients in our cohort had symptomatic intracereberal hemorrhage. Conclusion: Advanced MR imaging may help select patients with acute ischemic stroke and anterior circulation large vessel occlusion for embolectomy beyond the treatment window used in most endovascular trials.

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.
