Background and Purpose: Although the efficacy of endovascular treatment (EVT) in patients with anterior circulation ischemic stroke (AIS) is well documented, early neurological deterioration after EVT remains a serious issue associated with poor outcome. Besides obvious causes, such as lack of reperfusion, procedural complications, or parenchymal hemorrhage, early neurological deterioration may remain unexplained (UnEND). Our aim was to investigate predictors of UnEND after EVT in patients with AIS. Methods: Patients who underwent EVT for AIS, with an initial National Institutes of Health Stroke Scale score >5, Alberta Stroke Program Early CT Score ≥6, and included in a multicenter prospective observational registry were analyzed. Predictors of UnEND, defined as ≥4-point increase in the National Institutes of Health Stroke Scale score between baseline and day 1 after EVT, were determined via center-adjusted analyses. Results: Among the 1925 included in the analysis, 128 UnEND (6.6%) were recorded. In multivariate analysis, predictors of UnEND were diabetes mellitus (odds ratio [OR], 2.17 [95% CI, 1.32–3.56]), prestroke modified Rankin Scale score ≥2 (OR, 2.22 [95% CI, 1.09–4.55]), general anesthesia (OR, 2.55 [95% CI, 1.51–4.30]), admission systolic blood pressure (OR, 1.10 [95% CI, 1.01–1.20]), age (OR, 1.38 [95% CI, 1.14–1.67]), number of passes (OR, 1.16 [95% CI, 1.04–1.28]), direct admission or not to a comprehensive stroke center (OR, 0.49 [95% CI, 0.30–0.81]), and initial National Institutes of Health Stroke Scale score (OR, 0.65 [95% CI, 0.52–0.81]). Conclusions: Severely impaired AIS patients with nonmodifiable factors are more likely to develop UnEND. Some modifiable predictors of UnEND such as the number of EVT passes could be the object of improvement in AIS management.

Background Patients with acute ischemic stroke (AIS) caused by large vessel occlusion (LVO) were usually transferred from a primary stroke center (PSC) to a comprehensive stroke center (CSC) for endovascular treatment (drip-and-ship [DS]), while driving the doctor from a CSC to a PSC to perform a procedure is an alternative strategy (drip-and-drive [DD]). Purpose To compare the efficacy and prognosis of the two strategies. Material and Methods From February 2017 to June 2019, 62 patients with LVO received endovascular treatment via the DS and DD models and were retrospectively analyzed from the stroke alliance based on our CSC. Primary endpoint was door-to-reperfusion (DTR) time. Secondary endpoints included puncture-to-recanalization (PTR) time, modified Thrombolysis in Cerebral Infarction (mTICI) rates at the end of the procedure, and modified Rankin Scale (mRS) at 90 days. Results Forty-one patients received the DS strategy and 21 patients received the DD strategy. The DTR time was significantly longer in the DS group compared to the DD group (315.5 ± 83.8 min vs. 248.6 ± 80.0 min; P < 0.05), and PTR time was shorter (77.2 ± 35.9 min vs. 113.7 ± 69.7 min; P = 0.033) compared with the DD group. Successful recanalization (mTICI 2b/3) was achieved in 89% (36/41) of patients in the DS group and 86% (18/21) in the DD group ( P = 1.000). Favorable functional outcomes (mRS 0–2) were observed in 49% (20/41) of patients in the DS group and 71% (15/21) in the DD group at 90 days ( P = 0.089). Conclusion Compared with the DS strategy, the DD strategy showed more effective and a trend of better clinical outcomes for AIS patients with LVO.

Combined Use

RationaleMechanical thrombectomy (MT) using a stent retriever (SR) device is currently the recommended treatment in ischemic stroke due to anterior circulation large vessel occlusion. Combining contact aspiration (CA) with SR is a promising new treatment, although it was not found to be superior to SR alone as first-line treatment for achieving successful reperfusion.AimTo determine whether endovascular treatment combining first-line use of CA and SR is more efficient than SR alone.MethodsThe ASTER 2 clinical trial is a prospective, randomized, multicenter, open-label trial with a blinded endpoint. We included patients admitted with suspected anterior circulation ischemic stroke secondary to large vessel occlusion <8 hours from symptom onset. They were randomly allocated in a 1:1 ratio to one of two treatment groups (combined CA and SR or SR alone). In the case of failure of the assigned technique after three attempts, other adjunctive techniques were applied.Study outcomeThe primary outcome is the rate of successful/complete reperfusion (modified Thrombolysis In Cerebral Infarction (mTICI) score 2c/3) after the entire endovascular procedure. Secondary outcomes include reperfusion rates after the assigned first-line intervention alone and at the end of the procedure, procedural times, change in NIH Stroke Scale score at 24 hours, intracerebral hemorrhage at 24 hours, procedure-related serious adverse events, the modified Rankin Scale score, and all-cause mortality at 90 days and 1 year. The cost effectiveness of the two procedures will also be analyzed.DiscussionThis is the first head-to-head randomized trial to directly compare the efficacy of the combined use of CA and SR versus SR alone. This prospective trial aims to demonstrate the synergistic effects of CA and SR devices in first-line endovascular treatment.

The Impact

Background and Purpose: Evidence of an association between sleep apnea (SA) and early neurological deterioration (END) in acute phase ischemic stroke is scant. We investigated the prevalence of SA and the impact of SA severity on END in acute ischemic stroke (AIS) patients. Methods: We prospectively enrolled consecutive AIS patients admitted to our stroke unit within 72 hours of symptom onset. SA severity was assessed with ApneaLink - a validated portable respiratory monitor. SA was defined as an apnea-hypopnea index (AHI) of ≥ 5/hour. END was defined as an incremental increase in the National Institutes of Health Stroke Scale (NIHSS) score by ≥ 1 point in motor power, or ≥ 2 points in the total score within the first week after admission. Results: Of the 305 patients studied, 254 (83.3%) patients had SA (AHI ≥ 5/hour), and of these, 114 (37.4%) had mild SA (AHI 5-14/hour), 59 (19.3%) had moderate SA (AHI 15-29/hour), and 81 (26.6%) had severe SA (AHI ≥ 30/hour). Thirty-six (11.8%) patients experienced END: 2 of the 51 (3.9%) patients without SA and 34 of the 254 (14.4%) patients with SA. Multivariable regression analysis showed AHI independently predicted END (odds ratio 1.024; 95% confidence interval 1.006 to 1.042; p = 0.008). Conclusions: SA is common in the acute phase of ischemic stroke, and SA severity is associated with the risk of END.

Introduction: Endovascular treatment (EVT) is a widely proven method to treat patients diagnosed with intracranial large vessel occlusion. In order to ensure patients safety prior to and during EVT, preprocedural intubation has been adopted in many centers as a means for airway protection and immobilization. However, the correlation between site of vessel occlusion, need for intubation, and outcomes, has not yet been established. Methods: Through the utilization of a prospectively collected database at a comprehensive stroke center between 2012-2020, demographics, co-morbid conditions, intracerebral hemorrhage, mortality rate, and functional independence outcomes were examined. The outcomes and sites of occlusion between patients receiving mechanical thrombectomy (MT) treated while intubated versus those treated under conscious sedation (CS) were compared. Results: Out of 625 patients treated with MT, a total of 218 (34.9%) were treated while intubated (average age 70.3 ± 13.7, 37.2% women), and 407 (65.1%) were treated while under CS (average age 70.3 ± 13.7, 47.7% women); see Table 1 for baseline characteristics and outcomes. A higher number of patients requiring intubation had an occlusion in the basilar versus those only requiring CS. No differences were noted in regard to the proportion of patients receiving intubation or CS when treated for RMCA, LMCA, or internal carotid artery occlusions. Conclusion: Intubation + MT was associated with significantly worsened outcomes in regard to recanalization rates, functional outcome, and mortality. In anterior circulation strokes, intubation in RMCA patients were found to have poorer clinical outcome. Higher rates of intubation were also found to be needed in patients with basilar occlusions. Further research is required to determine whether site of occlusion dictates the need for intubation, and whether intubation allows for favorable outcome between R and LMCA occlusions.

Background Five randomized controlled trials recently demonstrated efficacy of endovascular treatment in acute ischemic stroke. Telestroke networks can improve stroke care in rural areas but their role in patients undergoing endovascular treatment is unknown. Aim We compared clinical outcomes of endovascular treatment between anterior circulation stroke patients transferred after teleconsultation and those directly admitted to a tertiary stroke center. Methods Data derived from consecutive patients with intracranial large vessel occlusion who underwent endovascular treatment from January 2010 to December 2014 at our tertiary stroke center. We compared baseline characteristics, onset-to-treatment times, symptomatic intracranial hemorrhage, in-hospital mortality, reperfusion (modified Treatment in Cerebral Infarction 2b/3), and favorable functional outcome (modified Rankin scale ≤ 2) at discharge between patients transferred from spoke hospitals and those directly admitted. Results We studied 151 patients who underwent emergent endovascular treatment for anterior circulation stroke: median age 70 years (interquartile range, 62–75); 55% men; median National Institutes of Health Stroke Scale score 15 (12–20). Of these, 48 (31.8%) patients were transferred after teleconsultation and 103 (68.2%) were primarily admitted to our emergency department. Transferred patients were younger (p = 0.020), received more frequently intravenous tissue plasminogen activator (p = 0.008), had prolonged time from stroke onset to endovascular treatment initiation (p < 0.0001) and tended to have lower rates of symptomatic intracranial hemorrhage (4.2% vs. 11.7%; p = 0.227) and mortality (8.3% vs. 22.6%; p = 0.041) than directly admitted patients. Similar rates of reperfusion (56.2% vs. 61.2%; p = 0.567) and favorable functional outcome (18.8% vs. 13.7%; p = 0.470) were observed in telestroke patients and those who were directly admitted. Conclusions Telestroke networks may enable delivery of endovascular treatment to selected ischemic stroke patients transferred from remote hospitals that is equitable to patients admitted directly to tertiary hospitals.

Background and Purpose— Interfacility transfers for thrombectomy in stroke patients with emergent large vessel occlusion (ELVO) are associated with longer treatment times and worse outcomes. In this series, we examined the association between Primary Stroke Center (PSC) door-in to door-out (DIDO) times and outcomes for confirmed ELVO stroke transfers and factors that may modify the interaction. Methods— We retrospectively identified 160 patients transferred to a single Comprehensive Stroke Center (CSC) with anterior circulation ELVO between July 1, 2015 and May 30, 2017. We included patients with acute occlusions of the internal carotid artery or proximal middle cerebral artery (M1 or M2 segments), with a National Institutes of Health Stroke Scale score of ≥6. Workflow metrics included time from onset to recanalization, PSC DIDO, interfacility transfer time, CSC arrival to arterial puncture, and arterial puncture to recanalization. Primary outcome measure was National Institutes of Health Stroke Scale at discharge and modified Rankin Scale (mRS) score at 90 days. Results— The median (Q1–Q3) age and National Institutes of Health Stroke Scale of the 130 ELVO transfers analyzed was 75 (64–84) and 17 (11–22). Intravenous alteplase was administered to 64% of patients. Regarding specific workflow metrics, median (Q1–Q3) times (in minutes) were 241 (199–332) for onset to recanalization, 85 (68–111) for PSC DIDO, 26 (17–32) for interfacility transport, 21 (16–39) for CSC door to arterial puncture, and 24 (15–35) for puncture to recanalization. Median discharge National Institutes of Health Stroke Scale score was 5 (2–16), and 46 (35%) patients had a favorable outcome at 90 days. Complete reperfusion (modified Thrombolysis in Cerebral Ischemia 2c/3) modified the deleterious association of DIDO on outcome. Conclusions— For patients diagnosed with ELVO at a PSC who are being transferred to a CSC for thrombectomy, longer DIDO times may have a deleterious effect on outcomes and may represent the single biggest modifiable factor in onset to recanalization time. PSCs should make efforts to decrease DIDO and routine use of DIDO as a performance measure is encouraged.

Background and Purpose: Although endovascular treatment (EVT) for acute ischemic stroke is classified as I evidence, outcomes after EVT in real-world practice appear to be less superior than those in randomized clinical trials (RCTs). Additionally, the effect of EVT is unclear compared with medical treatment (MT) for patients with mild symptoms defined by National Institutes of Health Stroke Scale score <6 or with severe symptoms defined by Alberta Stroke Program Early CT Score <6. Methods: Literatures were searched in big databases and major meetings from December 6, 2009, to December 6, 2019, including RCTs and observational studies comparing EVT against MT for patients with acute ischemic stroke. Observational studies were precategorized into 3 groups based on imaging data on admission: mild stroke group with National Institutes of Health Stroke Scale score <6, severe stroke group with Alberta Stroke Program Early CT Score <6 or ischemic core ≥50 mL, and normal stroke group for all others. Outcome was measured as modified Rankin Scale score of 0 to 2, mortality at 90 days, and symptomatic intracranial hemorrhage (sICH) at 24 hours. Results: Fifteen RCTs (n=3694) and 37 observational studies (n=9090) were included. EVT was associated with higher modified Rankin Scale 0 to 2 rate and lower mortality in RCTs and normal stroke group, whereas EVT was associated with higher sICH rate in normal stroke group, and no difference of sICH rate appeared between EVT and MT in RCTs. In severe stroke group, EVT was associated with higher modified Rankin Scale 0 to 2 rate and lower mortality, whereas no difference of sICH rate was found. In mild stroke group, there was no difference in modified Rankin Scale 0 to 2 rate between EVT and MT, whereas EVT was associated with higher mortality and sICH rate. Conclusions: Evidence from RCTs and observational studies supports the use of EVT as the first-line choice for eligible patients corresponding to the latest guideline. For patients with Alberta Stroke Program Early CT Score <6, EVT showed superiority over MT, also in line with the guidelines. On the contrary to the guideline, our data do not support EVT for patients with National Institutes of Health Stroke Scale score <6.

BackgroundPatients presenting with minor ischemic stroke frequently have early neurological deterioration (END) and poor final outcome. The optimal management of patients with END has not been determined.ObjectiveTo investigate rescue IA therapy (IAT) when patients with acute minor ischemic stroke develop END.MethodsThis was a retrospective study of consecutively registered patients with acute minor stroke and END. ‘END’ was defined as an increase in National Institutes of Health Stroke Scale (NIHSS) scores by 1 or more points (or development of new neurological symptoms) and ‘ΔEND−NIHSS’ was defined as numerical difference between NIHSS scores at the time of END and before END. Rescue IAT following END was adjusted for the covariates to evaluate the association between IAT and favorable outcome at 3 months.ResultsAmong 982 patients with acute minor ischemic stroke, END occurred in 232 (23.6%). Of the 209 patients with END with full data available, 87 (41.6%) had favorable outcomes at 3 months. Rescue IAT following END was performed in 28 (13.4%). Favorable 3-month outcomes were seen in 50% of patients undergoing rescue IAT, including 8/19 (42.1%) undergoing rescue IAT beyond 8 h. By multivariate logistic regression analysis, rescue IAT following END was independently associated with favorable outcome at 3 months (OR=10.9; 95% CI 3.06 to 38.84; p<0.001).ConclusionsThe results suggest that rescue IAT may be safe and effective when END occurs in selected patients with acute minor ischemic stroke. Further prospective and randomized studies are needed to confirm our results.

Background and Objective: The safety of eptifibatide in combination with IV tPA for ischemic stroke has recently been demonstrated in the CLEAR-ER trial which used .6 mg/kg IV tPA plus eptifibatide (135 mcg/kg bolus and .75mcg/kg/min two-hour infusion) versus standard tPA (.9 mg/kg). Prior studies have also looked into the combination of intra-arterial (IA) tPA and eptifibatide at dosing and duration similar to cardiology literature. Our aim was to compare the safety and efficacy of eptifibatide after full dose IV tPA and endovascular treatment versus full dose IV tPA and endovascular treatment alone. Materials and Methods: We reviewed the records and procedure reports of patients who underwent endovascular treatment for ischemic stroke from 2010-2013 at a university affiliated comprehensive stroke center. Patients who received full dose IV tPA (.9 mg/kg) followed by endovascular treatment were compared with those who had the same treatment, but also received a bolus of 135 mcg/kg of eptifibatide followed by a .5 mcg/kg/min for 20 hours (based on IMPACT-II trial protocol). The initial and discharge NIH Stroke Scale as well as the discharge mRS (DCmRS) were evaluated. A DCmRS of 0 or 1 was considered a favorable outcome, and 2 or more was considered as a unfavorable. Initial stroke severity (NIHSS) was analyzed with logistic regression for baseline comparison and Fisher’s exact test were used for categorical data analysis. Results: We evaluated 2,016 patients with ischemic stroke, of which 230 received IV tPA and 91 (55% female) underwent endovascular treatment, 44 of them also received eptifibatide. Of the 44 patients who received eptifibatide (bolus and 20 hour infusion), 18% (n=8) had a favorable outcome, and in the group that did not receive eptifibatide , 9% (n=4) had a favorable outcome (OR=2.389, 95% CI 0.6645 to 8.589, p= 0.2217). Conclusion: Eptifibatide in combination with full dose IV tPA and endovascular treatment did not increase morbidity in our patient population, and may have improved outcome. Further, larger trials need to be conducted for more definitive results.
