    Abstract: Hypotension during endovascular therapy for acute ischemic stroke is associated with worse functional outcomes (FO). Given its important role in intracranial hemodynamics, we investigated whether hypotension during endovascular therapy had the same effect on FO according to the posterior communicating artery (PComA) patency. Methods: We performed a post hoc analysis of the ASTER trial (Contact Aspiration Versus Stent Retriever for Successful Revascularization). Patients were included if they had middle cerebral artery occlusions. Primary outcome was favorable FO, defined by a modified Rankin Scale scores between 0 and 2 at 3 months. Results: One hundred forty-eight patients with middle cerebral artery occlusion were included. In patients with no PComA, an increase in minimum mean arterial pressure was positively associated with favorable FO (odds ratio per 10 mm Hg increase, 1.59 [95%CI, 1.11–2.25]; P =0.010), whereas no association was found in patients with a PComA (odds ratio, 0.77 [95% CI, 0.54–1.08]; P =0.12). Patients with no PComA and longer cumulative time with mean arterial pressure 〈 90 mm Hg or systolic blood pressure 〈 140 mm Hg had significantly lower rates of favorable FO, with an odds ratio per 10-minute increase of 0.75 (95% CI, 0.59–0.94; P =0.010) and 0.74 (95% CI, 0.60–0.91; P =0.003), but not in patients with a PComA. Conclusions: Hypotension during endovascular therapy for middle cerebral artery occlusion is consistently associated with worse FO in patients with no PComA but not in those with a PComA.

    Impact of Reperfusion for Nonagenarians Treated by Mechanical Thrombectomy : Insights From the ETIS Registry
    Ovid Technologies (Wolters Kluwer Health) ; 2019
    In:  Stroke Vol. 50, No. 11 ( 2019-11), p. 3164-3169

    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 50, No. 11 ( 2019-11), p. 3164-3169
    Abstract: Nonagenarians represent a growing stroke population characterized by a higher frailty. Although endovascular therapy (ET) is a cornerstone of the management of acute ischemic stroke related to large vessel occlusion, the benefit of reperfusion among nonagenarians is poorly documented. We aimed to assess the impact of ET-related reperfusion on the functional outcome of reperfusion in this elderly population. Methods— A retrospective analysis of clinical and imaging data from all patients aged over 90 included in the ETIS (Endovascular Treatment in Ischemic Stroke) registry between October 2013 and April 2018 was performed. Association between post-ET reperfusion and favorable (modified Rankin Scale [0–2] or equal to prestroke value) and good (modified Rankin Scale [0–3] or equal to prestroke value) outcome were evaluated. Demographic and procedural predictors of functional outcome, including the first-pass effect, were evaluated. Results were adjusted for center, admission National Institutes of Health Stroke Scale, and use of intravenous thrombolysis. Results— Among the 124 nonagenarians treated with ET, those with successful reperfusion had the lowest 90-day modified Rankin Scale (odds ratio, 3.26; 95% CI, 1.04–10.25). Only patients with successful reperfusion after the first pass (n=53, 56.7%) had a reduced 90-day mortality (odds ratio, 0.15; 95% CI, 0.05–0.45) and an increased rate of good outcome (odds ratio, 4.55; 95% CI, 1.38–15.03). No increase in the rate of intracranial hemorrhage was observed among patients successfully reperfused. Conclusions— Successful reperfusion improves the functional outcome of nonagenarians who should not be excluded from ET. The first-pass effect should be considered in the procedural management of this frail population.

    First-Pass Effect in Basilar Artery Occlusions: Insights From the Endovascular Treatment of Ischemic Stroke Registry
    Ovid Technologies (Wolters Kluwer Health) ; 2021

    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 52, No. 12 ( 2021-12), p. 3777-3785
    Abstract: In the settings of thrombectomy, the first-pass effect (FPE), defined by a complete recanalization after one pass with no rescue therapy, has been shown to be associated with an improved outcome. As this phenomenon has been predominantly described in anterior circulation strokes, we aimed to study the prevalence, outcomes, and predictors of FPE in patients with a basilar artery occlusion. Methods: From a prospective multicentric registry, we collected the data of all consecutive basilar artery occlusion patients who underwent thrombectomy and compared the outcomes of patients who achieved FPE and those who did not. We also compared FPE patients with those who achieved a complete recanalization with 〉 1 pass. Finally, a multivariate analysis was performed to determine the predictors of FPE. Results: Data from 280 patients were analyzed in our study, including 84 of 280 patients (30%) with an atheromatous etiology. An FPE was achieved in 93 patients (33.2%), with a significantly higher proportion of good outcomes (modified Rankin Scale score 0-2 at 3 months) and lower mortality than non-FPE patients. An FPE was also associated with improved outcomes compared with patients who went on to have full recanalization with 〉 1 pass. Contact aspiration as first-line strategy was a strong predictor of FPE, whereas baseline antiplatelets and atheromatous etiology were negative predictors. Conclusions: In our study, an FPE was achieved in approximately one-third of patients with a basilar artery occlusion and was associated with improved outcomes. More research is needed to improve devices and techniques to increase the incidence of FPE. Registration: URL: https://www.clinicaltrials.gov ; Unique identifier: NCT03776877.

    Predictors of the Aspiration Component Success of a Direct Aspiration First Pass Technique (ADAPT) for the Endovascular Treatment of Stroke Reperfusion Strategy in Anterior Circulation Acute Stroke
    Ovid Technologies (Wolters Kluwer Health) ; 2017

    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 48, No. 6 ( 2017-06), p. 1588-1593
    Abstract: A direct aspiration first pass technique (ADAPT) has been reported to be fast, safe, and effective for the treatment of acute ischemic stroke. The aim of this study is to determine the preoperative factors that affect success of the aspiration component of the technique in ischemic stroke patients with large vessel occlusion in the anterior circulation. Methods— We enrolled all 347 consecutive patients with anterior circulation acute ischemic stroke admitted for mechanical thrombectomy at our institution from August 2013 to October 2015 and treated by ADAPT for the endovascular treatment of stroke. Baseline and procedural characteristics, modified thrombolysis in cerebral infarction scores, and 3-month modified Rankin Scale were captured and analyzed. Results— Among the 347 patients (occlusion sites: middle cerebral artery=200, 58%; internal carotid artery Siphon=89, 25%; Tandem=58, 17%), aspiration component led to successful reperfusion (modified thrombolysis in cerebral infarction 2b/3 scores) in 55.6% (193/347 patients), stent retrievers were required in 40%, and a total successful final reperfusion rate of 83% (288/347) was achieved. Overall, procedural complications occurred in 13.3% of patients (48/347). Modified Rankin Scale score of 0 to 2 at 90 days was reported in 45% (144/323). Only 2 factors positively influenced the success of the aspiration component: an isolated middle cerebral artery occlusion ( P 〈 0.001) and a shorter time from stroke onset to clot contact ( P =0.018). Conclusions— In this large retrospective study, ADAPT was shown to be safe and effective for anterior circulation acute ischemic stroke with a final successful reperfusion achieved in 83%. The site of arterial occlusion and delay of the procedure were predictors for reperfusion. Clinical Trial Registration— URL: http://www.clinicaltrials.gov .

    Impact of Prior Antiplatelet Therapy on Outcomes After Endovascular Therapy for Acute Stroke: Endovascular Treatment in Ischemic Stroke Registry Results
    Ovid Technologies (Wolters Kluwer Health) ; 2021

    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 52, No. 12 ( 2021-12), p. 3864-3872
    Abstract: The influence of prior antiplatelet therapy (APT) uses on the outcomes of patients with acute ischemic stroke treated with endovascular therapy is unclear. We compared procedural and clinical outcomes of endovascular therapy in patients on APT or not before stroke onset. Methods: We analyzed 2 groups from the ongoing prospective multicenter Endovascular Treatment in Ischemic Stroke registry in France: patients on prior APT (APT+) and patients without prior APT (APT−) treated by endovascular therapy, with and without intravenous thrombolysis. Multilevel mixed-effects logistic models including center as random effect were used to compare angiographic (rates of reperfusion at the end of procedure, procedural complications) and clinical (favorable and excellent outcome, 90-day all-cause mortality, and hemorrhagic complications) outcomes according to APT subgroups. Comparisons were adjusted for prespecified confounders (age, admission National Institutes of Health Stroke Scale score, Alberta Stroke Program Early CT Score, intravenous thrombolysis, and time from onset to puncture), as well as for meaningful baseline between-group differences. Results: A total of 2939 patients were analyzed, of whom 877 (29.8%) were on prior APT. Patients with prior APT were older, had more frequent vascular risk factors, cardioembolic stroke mechanism, and prestroke disability. Rates of complete reperfusion (37.9% in the APT− group versus 42.7 % in the APT+ group; aOR, 1.09 [95% CI, 0.88–1.34]; P =0.41) and periprocedural complication (16.9% versus 13.3%; aOR, 0.90 [95% CI, 0.7–1.2]; P =0.66) did not differ between the two groups. Symptomatic intracerebral hemorrhage (aOR, 0.93 [95% CI, 0.63–1.37]; P =0.73), 3 months favorable clinical outcome (modified Rankin Scale score of 0–2; aOR, 0.98 [95% CI, 0.77–1.25]; P =0.89), and mortality (aOR, 0.95 [95% CI, 0.72–1.26]; P =0.76) at 90 days did not differ between the groups. Conclusions: Prior APT does not influence angiographic and functional outcomes following endovascular therapy and should not be taken into account for acute revascularization strategies.

    Abstract: Acute stroke patients with a large ischemic core may still benefit from mechanical thrombectomy (MT), but the predictors of clinical outcome are not well known after MT. We investigated the clinical and imaging factors associated with good outcome and mortality at 90 days in acute stroke patients with a large baseline ischemic core treated with MT. Methods— Data from the multicentric prospective ETIS (Endovascular Treatment in Ischemic Stroke) registry of consecutive acute ischemic stroke patients treated with MT from January 1, 2012, to August 31, 2016, were retrospectively analyzed. Baseline large ischemic core was defined as diffusion-weighted imaging (DWI)–Alberta Stroke Program Early CT Score of ≤5. The degree of disability was assessed by the modified Rankin Scale at 90 days. Outcomes included good outcome (modified Rankin Scale score of ≤2), and mortality (modified Rankin Scale score of 6). Results— Among 216 patients with DWI-Alberta Stroke Program Early CT Score of ≤5 (median DWI volume 77 mL, interquartile range 52–120 mL) treated with MT, good outcome was achieved in 55 (25.4%) patients and 75 (34.7%) died at 90 days. Hemorrhagic transformation was detected in 40 (18.5%) patients within 24 hours post-MT. Older age (adjusted odds ratio [OR] for every 10 years, 0.62; 95% CI, 0.48–0.80; P 〈 0.001) and increased DWI lesional volume (adjusted OR, 0.98; 95% CI, 0.97–0.99; P 〈 0.001) were associated with a lower chance of achieving a good outcome, while successful recanalization (modified Thrombolysis in Cerebral Infarction [mTICI] grades of ≤2b) predicted good outcome (adjusted OR, 4.56; 95% CI, 1.79–11.62; P =0.001). Successful recanalization (OR, 0.46; 95% CI, 0.22–0.97; P =0.042), increased DWI lesional volume (OR, 1.02; 95% CI, 1.01–1.03; P 〈 0.001), age (OR for every 10 years, 1.72; 95% CI, 1.31–2.26; P 〈 0.001), and diabetes mellitus (OR, 3.23; 95% CI, 1.34–7.8; P =0.009) were independent predictors of 90-day mortality. Conclusions— Successful recanalization and baseline DWI lesional volume are the strongest predictors of outcome in stroke patients with a large ischemic core.

    Local Anesthesia Without Sedation During Thrombectomy for Anterior Circulation Stroke Is Associated With Worse Outcome
    Ovid Technologies (Wolters Kluwer Health) ; 2020

    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 51, No. 10 ( 2020-10), p. 2951-2959
    Abstract: The best anesthetic management for mechanical thrombectomy of large vessel occlusion strokes is still uncertain and could impact the quality of reperfusion and clinical outcome. We aimed to compare the efficacy and safety outcomes between local anesthesia (LA) and conscious sedation in a large cohort of acute ischemic stroke patients with anterior circulation large vessel occlusion strokes treated with mechanical thrombectomy in current, everyday clinical practice. Methods: Patients undergoing mechanical thrombectomy for anterior large vessel occlusion strokes at 4 comprehensive stroke centers in France between January 1, 2018, and December 31, 2018, were pooled from the ongoing prospective multicenter observational Endovascular Treatment in Ischemic Stroke Registry in France. Intention-to-treat and per-protocol analyses were used. Results: Among the included 1034 patients, 762 were included in the conscious sedation group and 272 were included in the LA group. In the propensity score matched cohort, the rate of favorable outcome (90-day modified Rankin Scale score 0–2) was significantly lower in the LA group than in the conscious sedation group (40.0% versus 52.0%, matched relative risk=0.76 [95% CI, 0.60–0.97]), as well as the rate of successful reperfusion (modified Thrombolysis in Cerebral Infarction grade 2b–3; 76.6% versus 87.1%; matched relative risk=0.88 [95% CI, 0.79–0.98] ). There was no difference in procedure time between the 2 groups. In the inverse probability of treatment weighting-propensity score-adjusted cohort, similar significant differences were found for favorable outcomes and successful reperfusion. In inverse probability of treatment weighting-propensity score-adjusted cohort, a higher rate of 90-day mortality and a lower parenchymal hematoma were observed after LA. The sensitivity analysis restricted to our per-protocol sample provided similar results in the matched- and inverse probability of treatment weighting-propensity cohorts. Conclusions: In the Endovascular Treatment in Ischemic Stroke registry mainly included patients in early time window ( 〈 6 hours), LA was associated with lower odds of favorable outcome, successful reperfusion, and higher odds of mortality compared with conscious sedation for mechanical thrombectomy of large vessel occlusion.

    Mechanical Thrombectomy for Minor and Mild Stroke Patients Harboring Large Vessel Occlusion in the Anterior Circulation : A Multicenter Cohort Study
    Ovid Technologies (Wolters Kluwer Health) ; 2017
    In:  Stroke Vol. 48, No. 12 ( 2017-12), p. 3274-3281

    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 48, No. 12 ( 2017-12), p. 3274-3281
    Abstract: Proximal large vessel occlusion (LVO) is present in up to 30% of minor strokes. The effectiveness of mechanical thrombectomy (MT) in the subgroup of minor stroke with LVO in the anterior circulation is still open to debate. Data about MT in this subgroup of patients are sparse, and their optimal management has not yet been defined. The purpose of this multicenter cohort study was to evaluate the effectiveness of MT in patients experiencing acute ischemic stroke (AIS) because of LVO in the anterior circulation, presenting with minor-to-mild stroke symptoms (National Institutes of Health Stroke Scale score of 〈 8). Methods— Multicenter cohort study involving 4 comprehensive stroke centers having 2 therapeutic approaches (urgent thrombectomy associated with best medical treatment [BMT] versus BMT first and MT if worsening occurs) about management of patients with minor and mild acute ischemic stroke harboring LVO in the anterior circulation. An intention-to-treat analysis was conducted. The primary end point was the rate of excellent outcome defined as the achievement of a modified Rankin Scale score of 0 to 1 at 3 months. Results— Three hundred one patients were included, 170 with urgent MT associated with BMT, and 131 with BMT alone as first-line treatment. Patients treated with MT were younger, more often received intravenous thrombolysis, and had shorter time to imaging. Twenty-four patients (18.0%) in the medical group had rescue MT because of neurological worsening. Overall, excellent outcome was achieved in 64.5% of patients, with no difference between the 2 groups. Stratified analysis according to key subgroups did not find heterogeneity in the treatment effect size. Conclusions— Minor-to-mild stroke patients with LVO achieved excellent and favorable functional outcomes at 3 months in similar proportions between urgent MT versus delayed MT associated with BMT. There is thus an urgent need for randomized trials to define the effectiveness of MT in this patient subgroup.

    Abstract: In acute ischemic stroke patients, diffusion-weighted imaging (DWI)–Alberta Stroke Program Early Computed Tomography Score (ASPECTS) is correlated with infarct volume and is an independent factor of functional outcome. Patients with pretreatment DWI-ASPECTS ≤6 were excluded or under-represented in the recent randomized mechanical thrombectomy trials. Our aim was to assess the impact of reperfusion in pretreatment DWI-ASPECTS ≤6 patients treated with mechanical thrombectomy. Methods— We analyzed data collected between January 2012 and August 2015 in a bicentric prospective clinical registry of consecutive acute ischemic stroke patients treated with mechanical thrombectomy. Every patient with a documented internal carotid artery or middle cerebral artery occlusion with pretreatment DWI-ASPECTS ≤6 was eligible for this study. The primary end point was a favorable outcome defined by a modified Rankin Scale score ≤2 at 90 days. Results— Two hundred and eighteen patients with a DWI-ASPECTS ≤6 were included. Among them, 145 (66%) patients had successful reperfusion at the end of mechanical thrombectomy. Reperfused patients had an increased rate of favorable outcome (38.7% versus 17.4%; P =0.002) and a decreased rate of mortality at 3 months (22.5% versus 39.1%; P =0.013) compared with nonreperfused patients. The symptomatic intracranial hemorrhage rate was not different between the 2 groups (13.0% versus 14.1%; P =0.83). However, in patients with DWI-ASPECTS 〈 5, favorable outcome was low (13.0% versus 9.5%; P =0.68) with a high mortality rate (45.7% versus 57.1%; P =0.38) with or without successful reperfusion. Conclusions— Successful reperfusion is associated with reduced mortality and disability in patients with a pretreatment DWI-ASPECTS ≤6. Further data from randomized studies are needed, particularly in patients with DWI-ASPECTS 〈 5.

    Abstract: Parenchymal hematoma (PH) is a rare but dreadful complication of acute ischemic stroke with unclear underlying mechanisms. We aimed to study the incidence and predictors of PH after mechanical thrombectomy. Methods— Data from a prospective observational multicenter registry was screened to identify acute ischemic stroke patients with an anterior circulation large vessel occlusion who underwent mechanical thrombectomy. Clinical, imaging, and procedural characteristics were used for the analysis, including brain imaging systematically performed at 24 hours. PH occurrence was assessed according to ECASS (European Collaborative Acute Stroke Study) criteria. Univariate and multivariable analyses were performed to identify predictors of PH. Results— A total of 1316 patients were included in the study. PH occurred in 153 out of 1316 patients (11.6%) and was associated with a lower rate of favorable outcome and increased mortality. On multivariable analysis, age (per 1 year increase, odds ratio [OR], 1.01; 95% CI, 1.00–1.03; P =0.05), current smoking (OR, 2.02; 95% CI, 1.32–3.09; P 〈 0.01), admission Alberta Stroke Program Early CT Score (per a decrease of 1 point, OR, 1.70; 95% CI, 1.18–2.44; P 〈 0.01), general anesthesia (OR, 1.98; 95% CI, 1.36–2.90; P 〈 0.001), angiographic poor collaterals (OR, 2.13; 95% CI, 1.36–3.33; P 〈 0.001) and embolization in new territory (OR, 2.94; 95% CI, 1.70–5.10; P 〈 0.001) were identified as independent predictors of PH. Conclusions— PH occurred at a rate of 11.6% after mechanical thrombectomy, with high morbidity and mortality. Our study identified clinical, radiological, and procedural predictors of PH occurrence that can serve as the focus of future periprocedural management studies with the aim of reducing its occurrence.
