Introduction: Clinical trials have proven the safety and efficacy of mechanical thrombectomy (MT) with intravenous alteplase (tPA) compared to tPA alone in patients presenting with large vessel occlusion (LVO). The impact of tPA prior to MT on procedural metrics, successful revascularization, symptomatic hemorrhage and long-term functional outcome has not been established from large scale real-world studies. In this study we evaluate the impact of tPA prior to MT on procedural times, immediate and long-term outcomes. Methods: The STAR registry combined prospectively maintained databases of 11 thrombectomy-capable stroke centers in the US, Europe and Asia. Patients who received mechanical thrombectomy with or without intravenous tPA prior to MT were included in these analyses. Baseline characteristics, procedural time, successful revascularization (TICI ≥ 2B), symptomatic intracranial hemorrhage (PH2), and long-term functional outcomes were compared between the two groups. Results: Total of 1869 patients were included in this analysis. Of those, 907 received tPA prior to MT. Baseline features and outcomes are summarized in table 1. There were more white patients in the non-tPA group, and more patients in this group had atrial fibrillation and hyperlipidemia; otherwise there were no differences in baseline features between the two groups. Median NIHSS on admission was 16 in both groups, median ASPECTS was 9 in the tPA group versus 8 in the non-tPA group, p=0.208. Patients in the tPA group had higher rate of successful revascularization, lower number of revascularizations attempts and were more likely to achieve excellent long-term functional outcome. There was no difference in procedural time, rate of symptomatic hemorrhage or length of hospital stay. Conclusion: Bridging therapy with intravenous tPA prior to mechanical thrombectomy may facilitate MT and yield to better long-term functional outcome.

Background and Purpose: Endovascular therapy (EVT) for acute large vessel occlusion (LVO) is currently standard therapy, but it was associated with a higher incidence of intracranial hemorrhage (ICH) compared to conservative therapy. We investigated the impact of ICH within 72 hours on functional outcome at 90 days in patients with EVT for acute LVO. Methods: RESCUE-Japan Registry-2 was a multicenter registry enrolled 2420 consecutive patients with acute LVO within 24 hours of onset. We analyzed patients who received EVT and compared the functional outcomes between those with ICH (ICH group) and without ICH (No-ICH group) within 72 hours after onset. We estimated the adjusted odds ratio (OR) for good functional outcome as mRS 0-2 and mortality. We also explored the prognostic impact of symptomatic ICH (SICH) among those with ICH. Results: Among 2420 patients in the registry, 1281 received EVT and mean age was 75 years, and 759 (59.2%) were men. ICH occurred in 332 patients (25.9%). Good outcome was observed 80 patients (24.0%) and 454 patients (47.9%) in the ICH and No-ICH group, respectively, and the adjusted OR for good outcome of ICH group compared to No-ICH group was 0.30 (95% CI 0.22-0.42, p<0.0001). However, the mortalities within 90 days were not significantly different between groups (adjusted OR 1.13; 95% CI 0.72-1.76, p=0.59). SICH was observed in 35 patients (10.5%) among 332 patients with ICH, and the good outcomes were 8.6% and 25.9 % in patients with SICH and asymptomatic ICH (AICH), respectively (p=0.02). Mortality at 90 days were 31.4% and 7.0% in patients with SICH and AICH, respectively (p<0.0001). Conclusion: The functional outcomes at 90 days after onset was significantly worse in patients suffered ICH than the counterparts after EVT for acute LVO. However, the mortality rates were generally similar between those with and without ICH. Among patients with ICH, mortality was higher in patients with SICH, but mortality of the patients with AICH was similar to those without ICH.

AbstractData on the impact of kidney dysfunction on outcome in patients with stroke due to large vessel occlusion are scarce. The few available studies are limited by only considering single kidney parameters measured at one time point. We thus investigated the influence of both chronic kidney disease (CKD) and acute kidney injury (AKI) on outcome after mechanical thrombectomy. We included consecutive patients with anterior circulation large vessel occlusion stroke receiving mechanical thrombectomy at our center over an 8-year period. We extracted clinical data from a prospective registry and investigated kidney serum parameters at admission, the following day and throughout hospital stay. CKD and AKI were defined according to established nephrological criteria. Unfavorable outcome was defined as scores of 3–6 on the modified Rankin Scale 3 months post-stroke. Among 465 patients, 31.8% had an impaired estimated glomerular filtration rate (eGFR) at admission (< 60 ml/min/1.73 m2). Impaired admission eGFR was related to unfavorable outcome in univariable analysis (p = 0.003), but not after multivariable adjustment (p = 0.96). Patients frequently met AKI criteria at admission (24.5%), which was associated with unfavorable outcome in a multivariable model (OR 3.03, 95% CI 1.73–5.30, p < 0.001). Moreover, patients who developed AKI during hospital stay also had a worse outcome (p = 0.002 in multivariable analysis). While CKD was not associated with 3-month outcome, we identified AKI either at admission or throughout the hospital stay as an independent predictor of unfavorable prognosis in this study cohort. This finding warrants further investigation of kidney–brain crosstalk in the setting of acute stroke.

Introduction: CTP and MRI are increasingly used to assess endovascular thrombectomy (EVT) candidacy in large vessel occlusion stroke. Unfortunately, availability of these advanced neuroimaging techniques is not widespread and this can lead to over-triage to EVT-capable centers. Hypothesis: ASPECTS scoring applied to computed tomography angiography source images (CTA-SI) will be predictive of final infarct volume (FIV) and functional outcome. Methods: We reviewed data from consecutive patients undergoing EVT at our institution for anterior circulation occlusion between 01/14 - 01/19. We recorded demographics, comorbidities, NIHSS, treatment time parameters, and outcomes as defined by mRS (0-2 = good outcome). Cerebrovascular images were assessed by outcome-blinded raters and collateral score, TICI score, FIV, and both CT and CTA-SI ASPECTS scores were noted. Patients were grouped by ASPECTS score into low (0-4), intermediate (5-7), and high (8-10) for some analyses. FIV was predicted using a linear regression with NIHSS, good reperfusion (TICI 2b/3), collateral score, CT to groin puncture, CT and CTA-SI ASPECTS as independent variables. After excluding those with baseline mRS≥2, a binary logistic regression was performed including covariates of age, NIHSS, good reperfusion, and diabetes (factors significant at p<0.05 on univariate analysis) to assess the impact of CTA-SI ASPECTS group on outcome. Results: Analysis included 137 patients for FIV and 102 for outcome analysis (35 excluded for baseline mRS≥ 2). Linear regression found CTA-SI ASPECTS (Beta -10.8, p=0.002), collateral score (Beta -42.9, p=0.001) and good reperfusion (Beta 72.605, p=0.000) were independent predictors of FIV. Relative to the low CTA-SI ASPECTS group, the high CTA-SI ASPECTS group was more likely to have good outcome (OR 3.75 [95% CI 1.05-13.3]; p=0.41). CT ASPECTS was not predictive of FIV or good outcome. Outcomes: In those undergoing EVT for anterior circulation occlusion, CTA-SI ASPECTS is predictive of both FIV and functional outcome, while CT ASPECTS predicts neither. CTA-SI ASPECTS holds promise as a lower-cost, more widely available option for triage of patients with large vessel occlusion. Further study is needed comparing CTA-SI ASPECTS to CTP parameters.

<b><i>Introduction:</i></b> Endovascular treatment (EVT) is effective against acute cerebral large vessel occlusion (LVO). However, it has been associated with a high incidence of intracranial hemorrhage (ICH). Because the incidence of ICH and prognostic impact of ICH were not scrutinized in general patients, we investigated the impact of ICH after EVT on functional outcome at 90 days in patients with acute LVO. <b><i>Methods:</i></b> RESCUE-Japan Registry 2 was a multicenter registry that enrolled 2,420 consecutive patients with acute LVO within 24 h of onset. We analyzed 1,281 patients who received EVT and compared the functional outcomes between those with and without ICH (ICH and no-ICH groups, respectively) within 24 h after EVT. We explored the factors associated with ICH and prognostic impact of symptomatic ICH (SICH) among patients with ICH. We estimated the adjusted odds ratios (ORs) for good functional outcome as modified Rankin Scale scores 0–2 and mortality. We also explored the prognostic impact of symptomatic ICH (SICH) among patients with ICH. <b><i>Results:</i></b> ICH occurred in 333 patients (26.0%). Several factors such as perioperative edaravone, stent retriever, and baseline glucose were associated with development of ICH within 24 h. A good outcome was observed in 80 (24.0%) and 454 (47.9%) patients in the ICH and no-ICH groups, respectively, and the adjusted OR was 0.3 (95% confidence interval [CI] = 0.2–0.5, <i>p</i> &#x3c; 0.0001). Incidence of mortality within 90 days was not significantly different between the groups (adjusted OR 1.2; 95% CI: 0.7–1.9, <i>p</i> = 0.5). SICH was observed in 36 (10.8%) of 333 patients with ICH, and the good outcomes were 8.3 and 25.9% in patients with SICH and asymptomatic ICH (AICH), respectively (<i>p</i> = 0.02). Mortality at 90 days was 30.6 and 7.1% in patients with SICH and AICH, respectively (<i>p</i> &#x3c; 0.0001). <b><i>Conclusions:</i></b> The functional outcomes at 90 days were significantly worse in patients who developed ICH after receiving EVT for acute LVO, but the mortality was generally similar.

The Impact

The impact of heart failure on outcome in stroke patients is not fully understood. There is evidence for an increased mortality and morbidity, but it remains uncertain whether thrombectomy in patients with large vessel occlusion (LVO) in the anterior circulation is less effective in patients with heart failure compared to patients without. Retrospectively, we analyzed echocardiographic data of all patients in our stroke database, who underwent mechanical thrombectomy (n=668) for the presence of heart failure. Furthermore, we collected baseline characteristics and neurological and neuroradiological parameters. In the analysis, 373 of the 668 patients of our stroke database underwent echocardiography. Of these 373 patients, 90 patients (24%) suffered from heart failure with reduced left ventricular ejection fraction measured by echocardiography according to the current guidelines. After adjustment for age, the Alberta stroke program early CT score (ASPECTS), and time from symptom onset to recanalization, the analysis revealed that thrombectomy in patients with heart failure and LVO is not associated with less favorable outcome measured by the modified Rankin Scale after 90 days (3 (0-6) vs. 3 (1-5); p=0.380). Moreover, we could not find a significant difference in mortality compared to patients without heart failure (11.0% vs. 7.4%; p=0.313).

Introduction: Mechanical Thrombectomy (MT) is currently the standard of care for patients presenting with emergent large vessel occlusion (ELVO) with salvageable tissue. A subgroup of patients with ELVO are found to have refractory occlusion due to underlying intracranial atherosclerosis (ICAS), often requiring angioplasty with or without stenting. Whether this treatment is safe or effective in this group of patients remains to be established. The purpose of this study is to investigate the safety, efficacy and long-term outcome of MT with rescue therapy in patients with ICAS. Methods: STAR registry combined prospectively maintained databases of 11 thrombectomy-capable centers in the US, Europe and Asia. In this analysis, we included patients who underwent rescue balloon angioplasty and/or stenting in the setting of ELVO. A matched sample was produced by matching on the variables of age, admission NIHSS, and location of occlusion. Results: Out of 2827 thrombectomy patients included in STAR registry, 190 patients received MT and required rescue angioplasty and/or stenting. Balloon angioplasty was performed on 116 patients, and 84 patients had intracranial stenting. Compared to the 161 ICAS patients matched to similar number of controls. There was no difference in age, race, sex, rate of IV tPA administration, ASPECTS score, or onset to groin time. Successful first attempt was higher in patients with embolic LVO (22 vs 52, p=0.001), procedural time was longer in patients with ICAS (47 min Vs 31 min, p=<0.001). There was no difference in symptomatic intracranial hemorrhage, or long term functional outcome. Conclusion: In patients with ELVO with underlying ICAS requiring rescue angioplasty and/or stenting; despite longer procedural time and lower rate of first pass revascularization, rescue therapy appears to be safe with similar complication rates and long-term functional outcomes compared to patients with large vessel occlusion from embolic source.

The Impact

Introduction Endovascular treatment for acute ischemic stroke with acute large-vessel occlusion (ALVO) has established benefits, and rapid treatment is vital for mechanical thrombectomy in ALVO. Time from onset of stroke to groin puncture (OTP) is a practical and useful clinical marker, and OTP should be shortened to obtain the maximum benefit of thrombectomy. Objective The aim of the present study was to assess the impact of early treatment of anterior circulation stroke within three hours after symptom onset and to evaluate the role of OTP in determining outcomes after endovascular therapy. Methods Consecutive patients with acute stroke due to major artery (internal carotid or middle cerebral arteries) occlusion who underwent endovascular recanalization between March 2014 and January 2017 were retrospectively evaluated. Patients were stratified by OTP into three categories: 0–≤3 h, >3–≤6 h, and >6 h. The primary outcome measure was a 90-day modified Rankin scale score of 0–2 (good outcome). Results Data were analyzed from 100 patients (mean age, 76.6 years; mean National Institutes of Health Stroke Scale score, 17). Groin puncture occurred within 0–≤3 h in 51 patients, >3–≤6 h in 28, and >6 h in 21. Median OTP in each group was 126 min (range, 57–168 min), 238 min (range, 186–360 min) and 728 min (range, 365–1492 min), respectively. On multivariable logistic regression analysis, category of OTP represented an independent predictor of patient outcome (adjusted odds ratio, 0.48; 95% confidence interval, 0.25–0.93; p = 0.029). Conclusions OTP is a prehospital and in-hospital workflow-based indicator. In this single-center study, OTP was found to independently affect functional outcomes after endovascular stroke treatment.

Acute ischemic stroke is one of the leading causes of morbidity and mortality in America and the leading cause of adult long-term disability. Strokes due to emergent large vessel occlusion (ELVO) often lead to significant disability; however, they also can be amenable to treatment with the potential for good functional outcome. Over a short period, the standard of treatment has evolved considerably, from supportive care to systemic therapy and now to targeted therapy. The role for mechanical thrombectomy had been debated for years, but in light of five back-to-back publications demonstrating its superiority, it is now considered standard of care in those patients who meet criteria. This article aims to introduce the reader to the progression of events leading to the current practice of endovascular embolectomy in ELVO.

ObjectivePermissive hypertension may benefit patients with non-recanalized large vessel occlusion (nrLVO) post mechanical thrombectomy (MT) by maintaining brain perfusion. Data evaluating the impact of post-MT blood pressure (BP) levels on outcomes in nrLVO patients are scarce. We investigated the association of the post-MT BP course with safety and efficacy outcomes in nrLVO.MethodsHourly systolic BP (SBP) and diastolic BP (DBP) values were prospectively recorded for 24 hours following MT in consecutive nrLVO patients. Maximum, minimum, and mean BP levels were documented. Three-month functional independence (FI) was defined as modified Rankin Scale (mRS) scores of 0–2.ResultsA total of 88 nrLVO patients were evaluated post MT. Patients with FI had lower maximum SBP (160±19 mmHg vs 179±23 mmHg; P=0.001) and higher minimum SBP levels (119±12 mmHg vs 108±25 mmHg; P=0.008). Maximum SBP (183±20 mmHg vs 169±23 mmHg; P=0.008) and DBP levels (105±20 mmHg vs 89±18 mmHg; P=0.001) were higher in patients who died at 3 months while minimum SBP values were lower (102±28 mmHg vs 115±16 mmHg; P=0.007). On multivariable analyses, both maximum SBP (OR per 10 mmHg increase: 0.55, 95% CI 0.39 to 0.79; P=0.001) and minimum SBP (OR per 10 mmHg increase: 1.64, 95% CI 1.04 to 2.60; P=0.033) levels were independently associated with the odds of FI. Maximum DBP (OR per 10 mmHg increase: 1.61; 95% CI 1.10 to 2.36; P=0.014) and minimum SBP (OR per 10 mmHg increase: 0.65, 95% CI 0.47 to 0.90; P=0.009) values were independent predictors of 3-month mortality.ConclusionsOur study demonstrates that wide BP excursions from the mean during the first 24 hours post MT are associated with worse outcomes in patients with nrLVO.
