BackgroundThe predictors of successful reperfusion and the effect of reperfusion after endovascular treatment (EVT) for M2 occlusions have not been well studied. We aimed to identify predictors of successful reperfusion and the effect of reperfusion on outcomes of EVT for M2 occlusions in current practice.MethodsPatients with acute ischemic stroke due to isolated M2 occlusions who were enrolled in the prospective multicenter Endovascular Treatment in Ischemic Stroke (ETIS) Registry in France between January 2015 and March 2020 were included. The primary outcome was a favorable outcome, defined as modified Rankin Scale (mRS) score of 0–2 at 90 days. Successful reperfusion was defined as an improvement of ≥1 points in the modified Thrombolysis In Cerebral Infarction score between the first and the last intracranial angiogram.ResultsA total of 458 patients were included (median National Institutes of Health Stroke Scale (NIHSS) score 14; 61.4% received prior intravenous thrombolysis). Compared with the non-reperfused patients, reperfused patients had an increased rate of excellent outcome (OR 2.3, 95% CI 0.98 to 5.36; p=0.053), favorable outcome (OR 2.79, 95% CI 1.31 to 5.93; p=0.007), and reduced 90-day mortality (OR 0.39, 95% CI 0.19 to 0.79; p<0.01). Admission NIHSS score was the only predictor of successful reperfusion. First-line strategy was not a predictor of successful reperfusion or favorable outcome, but the use of a stent retriever, alone or with an aspiration catheter, was associated with higher rates of procedural complications and 90-day mortality.ConclusionsSuccessful reperfusion of M2 occlusions reduced disability and mortality. However, safety is a concern, especially if the procedure failed.

Procedural Time

Background: Recent single center studies have suggested that “procedural time” independent of “time to procedure” can affect outcomes of acute ischemic stroke patients undergoing endovascular treatment (ET). We performed a pooled analysis from three ET trials to determine the effect of procedural time on angiographic and clinical outcomes. Objective: To determine the relationship between procedural time and clinical outcomes among acute ischemic stroke patients undergoing successful recanalization with ET. Methods: We analyzed data from SWIFT, STAR and SWIFT PRIME trials. Baseline demographic and clinical characteristics, NIHSS score on admission, intracranial hemorrhage rates and mRS at 3 months post procedure were analyzed. TICI scale was used to grade post procedure angiographic recanalization. Procedural time was defined by the time interval between groin puncture and recanalization. We estimated the procedural time after which favorable clinical outcome was unlikely even after recanalization (futile) after age and NIHSS score adjustment. Results: We analyzed 301 patients who underwent ET and had near complete or complete recanalization (TICI 2b or 3). The procedural time (±SD) was significantly shorter in patients who achieved a favorable outcome (mRS 0-2) compared with those who did not achieve favorable outcome (44±25 vs 51±33 minutes, p=0.04). Table 1. In the multivariate analysis (including all baseline characteristics with a p value <0.05 as independent variables), shorter procedural time was a significant predictor of lower odds of unfavorable outcome (OR 0.49, 95% CI 0.28, 0.85, p=0.012). The rates of favorable outcomes were significantly higher when the procedural time was <60 minutes compared with ≥60 minutes (62% vs 45%, p=0.020). Conclusion: Procedural time in patients undergoing mechanical thrombectomy for acute ischemic stroke is an important determinant of favorable outcomes in those with near complete or complete recanalization.

A New Technique

BackgroundThe development of new revascularization devices has improved recanalization rates and time, but not clinical outcomes. We report a prospectively collected clinical experience with a new technique utilizing a direct aspiration first pass technique with large bore aspiration catheter as the primary method for vessel recanalization.Methods98 prospectively identified acute ischemic stroke patients with 100 occluded large cerebral vessels at six institutions were included in the study. The ADAPT technique was utilized in all patients. Procedural and clinical data were captured for analysis.ResultsThe aspiration component of the ADAPT technique alone was successful in achieving Thrombolysis in Cerebral Infarction (TICI) 2b or 3 revascularization in 78% of cases. The additional use of stent retrievers improved the TICI 2b/3 revascularization rate to 95%. The average time from groin puncture to at least TICI 2b recanalization was 37 min. A 5MAX demonstrated similar success to a 5MAX ACE in achieving TICI 2b/3 revascularization alone (75% vs 82%, p=0.43). Patients presented with an admitting median National Institutes of Health Stroke Scale (NIHSS) score of 17.0 (12.0–21.0) and improved to a median NIHSS score at discharge of 7.3 (1.0–11.0). Ninety day functional outcomes were 40% (modified Rankin Scale (mRS) 0–2) and 20% (mRS 6). There were two procedural complications and no symptomatic intracerebral hemorrhages.DiscussionThe ADAPT technique is a fast, safe, simple, and effective method that has facilitated our approach to acute ischemic stroke thrombectomy by utilizing the latest generation of large bore aspiration catheters to achieve previously unparalleled angiographic outcomes.

Background: The benefit of alteplase in minor non-disabling acute ischemic stroke (AIS) is unknown. We aimed to explore the clinical efficacy of alteplase-treatment in minor non-disabling stroke in clinical practice. Methods: We used a prospectively collected database of AIS patients who were being assessed for thrombolysis with alteplase. Minor non-disabling AIS was identified as patients with baseline National Institutes of Health Stroke Scale (NIHSS) score ≤ 5 and a score 0 or 1 on each baseline NIHSS score item (items 1a to 1c being 0). Results: A total of 461 patients with minor non-disabling AIS were included and among them 240 (52.1%) patients were treated with alteplase and 113 (24.5%) patients had severe stenosis/occlusion of large vessels. No significant association of 90-day excellent outcome was found with alteplase-treatment (77.1% vs. 80.5%, p 1 = 0.425; OR 0.911, 95% CI 0.428 to 1.940; p 2 = 0.808). However, among patients with severe stenosis/occlusion of large vessels, alteplase-treatment was independently associated with excellent outcome (74.4% vs. 45.7%, p 1 = 0.005; OR 4.709, 95% CI 1.391 to 11.962; p 2 = 0.010). Conclusion: Although alteplase-treatment did not result in an excellent outcome in general minor non-disabling stroke patients, it may work in those specific patients who had severe stenosis/occlusion of large vessels.

ObjectiveAsymptomatic intracranial hemorrhage (aSICH) is a common phenomenon after endovascular treatment of acute ischemic stroke, but its prognostic impacts remain unclear. This study evaluated functional outcomes of thrombectomy in patients with and without aSICH.MethodsPatients with acute ischemic stroke due to large artery occlusion in the anterior circulation who were treated with thrombectomy were enrolled in 21 centers. According to CT scans performed within 72 hours of endovascular procedures, patients with aSICH or without intracranial hemorrhage were included while patients with symptomatic intracranial hemorrhage (SICH) were excluded. Baseline data and functional outcomes were compared between patients with aSICH and those without intracranial hemorrhage. Logistic regression analysis was applied to evaluate the impacts of aSICH on functional outcomes.ResultsOf the 632 patients with endovascular treatment, 101 (16.0%) were classified as having SICH, 212 (33.5%) as having aSICH, and 319 (50.5%) as being without intracranial hemorrhage. Patients with aSICH after endovascular treatment had a lower ratio of excellent outcome (mRS 0–1, OR 0.53; 95% CI 0.33 to 0.84, P=0.007) than those without intracranial hemorrhage. There were no significant differences concerning favorable outcome (mRS 0–2, OR 0.76; 95% CI 0.50 to 1.14, P=0.185) or mortality (OR 0.64; 95% CI 0.38 to 1.09, P=0.101) between patients with aSICH and those without intracranial hemorrhage.ConclusionsIn an Asian population, aSICH after thrombectomy may decrease the likelihood of an excellent functional outcome but does not influence a favorable outcome and mortality in patients with ischemic stroke due to large artery occlusion in the anterior circulation.

The Relationship

Background: Intravenous thrombolysis (IVT) therapy is currently one of the best medical treatments available for patients with acute ischemic stroke. Studies have shown that blood pressure (BP) changes in patients treated with IVT are significantly correlated with prognosis.Objective: Our study aimed to determine the relationship between BP changes during recombinant tissue plasminogen activator (rt-PA) infusion and the 3-month prognosis evaluated using the modified Rankin Scale (mRS) and determine the factors influencing BP changes during rt-PA infusion.Methods: Consecutive patients who were treated with IVT and admitted to our stroke center between May 2015 and October 2017 were analyzed retrospectively. Patients were divided into two groups according to their 3-month prognosis status: patients with mRS ≤ 2 were defined as “favorable outcome group” and those with mRS ≥ 3 as “unfavorable outcome group”. First, the factors affecting prognosis after thrombolysis were analyzed. Second, we analyzed the relationship between BP and the prognosis. BP was taken before and at regular intervals of 15 min during the rt-PA infusion (1 h). The average value of BP during thrombolysis was calculated and compared to the baseline BP. BP decrease was defined as the difference between the baseline BP and the average BP, provided it was greater than 0 mmHg. Third, univariate and multivariate analyses were performed to identify factors that may contribute to BP decrease.Results: In total, 458 patients were included. Patients with a lower baseline National Institute of Health Stroke Scale (NIHSS) score (8.25 ± 5.57 vs. 13.51 ± 7.42, P &lt; 0.001), a higher Alberta Stroke Program Early CT Score (ASPECTS; 8.65 ± 1.82 vs. 8.13 ± 2.00, P = 0.005), decreased BP during thrombolysis (69.4% vs. 59.8%, P = 0.037), and steady BP (SD &lt; 10 mmHg) were more likely to have a favorable outcome (73.9% vs. 60.6%, P = 0.019). High baseline BP (OR &gt; 1), hypertension history (OR &lt; 1), and baseline ASPECTS (OR &gt; 1) were independent factors of BP change during thrombolysis.Conclusion: Patients with decreased or steady BP during thrombolysis were more likely to have a favorable outcome. Baseline ASPECTS, baseline NIHSS score, and hypertension history influenced BP changes during thrombolysis.

OBJECTIVEMechanical thrombectomy using a Solitaire stent retriever has been widely applied as a safe and effective method in adult acute ischemic stroke (AIS). However, due to the lack of data, the safety and effectiveness of mechanical thrombectomy using a Solitaire stent in pediatric AIS has not yet been verified. The purpose of this study was to explore the safety and effectiveness of mechanical thrombectomy using a Solitaire stent retriever for pediatric AIS.METHODSBetween January 2012 and December 2017, 7 cases of pediatric AIS were treated via mechanical thrombectomy using a Solitaire stent retriever. The clinical practice, imaging, and follow-up results were reviewed, and the data were summarized and analyzed.RESULTSThe ages of the 7 patients ranged from 7 to 14 years with an average age of 11.1 years. The preoperative National Institutes of Health Stroke Scale (NIHSS) scores ranged from 9 to 22 with an average of 15.4 points. A Solitaire stent retriever was used in all patients, averaging 1.7 applications of thrombectomy and combined balloon dilation in 2 cases. Grade 3 on the modified Thrombolysis In Cerebral Infarction scale of recanalization was achieved in 5 cases and grade 2b in 2 cases. Six patients improved and 1 patient died after thrombectomy. The average NIHSS score of the 6 cases was 3.67 at discharge. The average modified Rankin Scale score was 1 at the 3-month follow-up. Subarachnoid hemorrhage after thrombectomy occurred in 1 case and that patient died 3 days postoperatively.CONCLUSIONSThis study shows that mechanical thrombectomy using a Solitaire stent retriever has a high recanalization rate and excellent clinical prognosis in pediatric AIS. The safety of mechanical thrombectomy in pediatric AIS requires more clinical trials for confirmation.

Recent randomized controlled clinical trials (RCTs) have revolutionized acute ischemic stroke care by extending the use of intravenous thrombolysis and endovascular reperfusion therapies in time windows that have been originally considered futile or even unsafe. Both systemic and endovascular reperfusion therapies have been shown to improve outcome in patients with wake-up strokes or symptom onset beyond 4.5 h for intravenous thrombolysis and beyond 6 h for endovascular treatment; however, they require advanced neuroimaging to select stroke patients safely. Experts have proposed simpler imaging algorithms but high-quality data on safety and efficacy are currently missing. RCTs used diverse imaging and clinical inclusion criteria for patient selection during the dawn of this novel stroke treatment paradigm. After taking into consideration the dismal prognosis of nonrecanalized ischemic stroke patients and the substantial clinical benefit of reperfusion therapies in selected late presenters, we propose rescue reperfusion therapies for acute ischemic stroke patients not fulfilling all clinical and imaging inclusion criteria as an option in a subgroup of patients with clinical and radiological profiles suggesting low risk for complications, notably hemorrhagic transformation as well as local or remote parenchymal hemorrhage. Incorporating new data to treatment algorithms may seem perplexing to stroke physicians, since treatment and imaging capabilities of each stroke center may dictate diverse treatment pathways. This narrative review will summarize current data that will assist clinicians in the selection of those late presenters that will most likely benefit from acute reperfusion therapies. Different treatment algorithms are provided according to available neuroimaging and endovascular treatment capabilities.

BackgroundDespite successful recanalization after endovascular treatment, many patients with acute ischemic stroke due to large vessel occlusion still show functional dependence, namely futile recanalization.MethodsPubMed and Embase were searched up to April 30, 2021. Studies that reported risk factors for futile recanalization following endovascular treatment of acute ischemic stroke were included. The mean difference (MD) or odds ratio (OR) and 95% confidence interval (95% CI) of each study were pooled for a meta-analysis.ResultsTwelve studies enrolling 2138 patients were included. The pooled analysis showed that age (MD 5.81, 95% CI 4.16 to 7.46), female sex (OR 1.40, 95% CI 1.16 to 1.68), National Institutes of Health Stroke Scale (NIHSS) score (MD 4.22, 95% CI 3.38 to 5.07), Alberta Stroke Program Early CT Score (ASPECTS) (MD −0.71, 95% CI −1.23 to –0.19), hypertension (OR 1.73, 95% CI 1.43 to 2.09), diabetes (OR 1.78, 95% CI 1.41 to 2.24), atrial fibrillation (OR 1.24, 95% CI 1.01 to 1.51), admission systolic blood pressure (MD 4.98, 95% CI 1.87 to 8.09), serum glucose (MD 0.59, 95% CI 0.37 to 0.81), internal carotid artery occlusion (OR 1.85, 95% CI 1.17 to 2.95), pre-treatment intravenous thrombolysis (OR 0.67, 95% CI 0.55 to 0.83), onset-to-puncture time (MD 16.92, 95% CI 6.52 to 27.31), puncture-to-recanalization time (MD 12.37, 95% CI 7.96 to 16.79), and post-treatment symptomatic intracerebral hemorrhage (OR 6.09, 95% CI 3.18 to 11.68) were significantly associated with futile recanalization.ConclusionThis study identified female sex, comorbidities, admission systolic blood pressure, serum glucose, occlusion site, non-bridging therapy, and post-procedural complication as predictors of futile recanalization, and also confirmed previously reported factors. Further large-scale prospective studies are needed.

Background: Large vessel occlusions with a high clot burden are less likely to improve with the FDA-approved IV strategy. Endovascular therapy within the first 3 h of stroke symptom onset provides an effective alternative treatment in patients with large vessel occlusion. It is not clear if combination of IV thrombolysis and endovascular approach is superior to endovascular treatment alone. Methods: We retrospectively reviewed all cases of acute ischemic stroke with large vessel occlusion treated within the first 3 h stroke onset during the 2005-2010 period. First group received endovascular therapy within the first 3 h of stroke onset. Second group consisted of patients who received IV thrombolysis within the first 3 h followed by endovascular therapy. We compared the following outcomes: revascularization rates, NIHSS score at discharge, mRS at discharge and 3months, symptomatic hemorrhage rates and mortality. Results: Among 104 patients identified, 42 received combined therapy, and 62 received endovascular therapy only. The two groups had similar demographic (age and sex distribution) and vascular risk factors distribution, as well as NIHSS score on admission (14.8±4.7 and 16.0±5.3; p=0.23). We found no difference in TIMI recanalization rates (Thrombolysis in Myocardial Infarction scale score of 2 or 3) following combined or endovascular therapy alone (83.3% and 79.0%; p=0.59). A preferred outcome, defined as a mRS of 2 or less at 90 days also did not differ between the combined therapy group and the endovascular only group (37.5% and 34.5%; p=0.76). There was no difference in mortality rate (22.5% and 31.0%; p=0.36) and the rate of symptomatic intracranial hemorrhage (9.5% and 8.1%; p=0.73). There was a significant difference in mean time from symptom onset to endovascular treatment between the combined group (227±88 min) and endovascular only group (125±40 min; p<0.0001).Patients with good TIMI recanalization rate of 2 or 3 showed a trend of having a better mRS at 90 days in both bridging (16.67% vs. 41.18%, p-value: 0.3813) and endovascular groups (25% vs. 34.78%, p-value: 0.7326).When analyzing the correlation of mRS at 90 days with the site of occlusion, patients in the bridging group showed a trend of a better outcome when the site of occlusion was ICA (33.3% vs 30%) and MCA (66.67% vs. 27.59%) and worse outcome when the site of occlusion was in the posterior circulation (26.32% vs. 50%), however, these results were not statistically significant (p-values: 0.1735& 0.5366). Conclusion: Combining IV thrombolysis and endovascular therapy achieves similar rates of clinical outcomes, revascularization rates, complications and mortality rates, when compared with endovascular treatment alone. The combined therapy, however, significantly delays initiation of endovascular treatment. A randomized prospective trial comparing both treatment strategies in acute ischemic stroke is warranted
