SUMMARY Background: To compare the treatment efficacy of different types of endovascular mechanical embolectomy in acute ischemic stroke (AIS). Material and Methods: A total of 89 patients with AIS were selected in our hospital from January 2014 to January 2016 and divided into tPA group (n=27), tPA+Trevo group (n=30) and tPA+Solitaire FR group (n=32) for different treatments. Treatment effectiveness was evaluated using NIHSS and mRS system. The NIHSS score, vascular recanalization rate and postoperative complications were compared among groups. Results: The NIHSS score of the tPA group was significantly lower than that of other two groups at 1 d after the operation (p < 0.05), but it was significantly higher than that of other two groups at 3 d and 3 w after the operation (p < 0.05). After the treatment, no significant difference in NIHSS score was found between the tPA+Trevo and tPA Solitaire FR groups. The revascularization rate was significantly higher, but the mortality rate in 90 d was significantly lower in the tPA+Trevo and tPA+Solitaire FR groups than that in the tPA group (p < 0.05), and no significant difference was found between the tPA+Trevo and tPA+Solitaire FR groups. The incidence rate of symptomatic intracranial hemorrhage was significantly lower in the tPA+Solitaire FR group than that in tPA+Trevo group (p < 0.05) or tPA group (p < 0.01). Significantly more patients with mRS no higher than 2 points were found in the tPA+Trevo and tPA+Solitaire FR groups than those in tPA group (p < 0.05), and no significant difference was found between the tPA+Trevo and tPA+Solitaire FR groups. Conclusion: TPA+Solitaire FR is a type of thrombectomy that is superior to tPA and tPA+Trevo in the treatment of patients with AIS.

Objective: This study analyzed the efficacy and safety of low-dose and standard-dose alteplase intravenous thrombolytic therapy for acute ischemic stroke (AIS). Methods: Patients with AIS who underwent intravenous alteplase thrombolysis from July 2012 to December 2016 were retrospectively analyzed and correspondingly divided into low-dose (0.6–0.89 mg/kg) group and standard-dose group (0.9 mg/kg) according to alteplase dosage. The clinical outcome was evaluated by modified Rankin Scale (mRS) at 90 days after onset. The safety index was the mortality at 90 days after onset and the incidence of symptomatic intracranial hemorrhage (SICH) within 7 days. Results: A total of 1,486 patients were included (1,115 cases in low-dose group and 371 cases in standard-dose group). There were no significant differences in baseline data between the 2 groups. As mRS, good outcome rate as well as mortality rate in both groups had no significant difference (36.1 vs. 37.6%; χ2 = 10.882, p = 0.890; 5.5 vs. 7.3%; χ2 = 2.163, p = 0.076), but the incidence of SICH in low-dose group was significantly lower than that of the standard-dose group (2.2 vs. 5.9%; χ2 = 3.157, p = 0.001). Conclusion: The efficacy of low-dose alteplase intravenous thrombolytic therapy for AIS was equivalent to the standard-dose regimen but with higher safety.

Symptomatic Intracranial Hemorrhage

Background: Intravenous thrombolysis is the preferred clinical treatment for acute ischemic stroke. Alteplase is an intravenous thrombolytic drug used in clinical practice. Recently, studies have shown the efficacy of another intravenous thrombolytic drug, tenecteplase, and have reported that the risk of bleeding is low. However, at present, Chinese and international research has yielded controversial results regarding the efficacy and risks of tenecteplase. Therefore, this systematic review and meta- analysis of the efficacy and safety of tenecteplase were performed. Methods: PubMed, the Cochrane Library, MEDLINE, the Wanfang Database and CNKI were searched for all studies on the thrombolytic treatment of acute ischemic stroke. All studies published in English prior to March 2021 were retrieved. The studies were screened and selected based on the inclusion and exclusion criteria. Then, the data were extracted and recorded by trained researchers. RevMan 5.4 statistical software was used to analyze the data on the 24h recanalization rate, early neurological improvement (24h reduction in the National Institutes of Health Stroke Scale [NIHSS] score of at least 8 points or 24 h NIHSS score of 0~1 point), mRS score at 90 days, intracranial hemorrhage, symptomatic intracranial hemorrhage and mortality in the tenecteplase group and alteplase group. Results: A total of 565 related studies were identified through the initial searches in each database. The citations of meta-analyses and related reviews were screened for additional eligible articles. Eventually, 9 high-quality English-language articles that included 2149 patients with acute ischemic stroke (including 1035 in the tenecteplase group and 1046 in the alteplase group)were included in this meta-analysis. The meta-analysis results were as follows: (1) Efficacy: The 24 h recanalization rate with regard to vascular recanalization was significantly better in the tenecteplase group than in the alteplase group(OR = 1.83, 95% CI: 1.23~2.72, z = 2.97, P = 0.003). There was significantly greater improvement in early neurological function in the tenecteplase group than in the alteplase group (OR= 1.34, 95% CI: 1.11~1.63, Z=3.00, P =0.003). There were no significant differences in 90-day mRS scores between the two groups (mRS score =0-1, OR = 1.20, 95% CI: 0.99~1.46, z = 1.82, p = 0.07; mRS score =0-2, OR = 1.17, 95% CI: 0.94~1.45, z = 1.38, p = 0.17). However, the subgroup analysis showed that the 90-day mRS score of the 0.25 mg/kg tenecteplase group was significantly different from that of groups treated with other doses of tenecteplase (OR = 1.48, 95% CI: 1.01~2.03, z = 2.03, p = 0.04). (2) Safety: The incidences of any intracranial hemorrhage (OR = 0.91, 95% Ci: 0.55~1.49, z = 0.39, p = 0.70), symptomatic intracranial hemorrhage (OR = 1.21, 95% CI: 0.63~2.32, z = 0.56 P = 0.57), and mortality (OR = 0.85, 95% CI: 0.57~1.26, z = 0.82, p = 0.41) were not significantly different between the tenecteplase and alteplase groups. Conclusions: Tenecteplase can significantly increase the 24-hour vascular recanalization rate and improve the neurological prognosis of patients with acute ischemic stroke and it does not increase the risk of intracranial hemorrhage or mortality.

Symptomatic Intracranial Hemorrhage

Background: Patients with acute ischemic stroke (AIS) due to atrial fibrillation (afib) may have increased complications from intravenous thrombolysis or endovascular treatment (ET) compared to other stroke subtypes. The purpose of this study was to compare the rates of symptomatic intracranial hemorrhage (sICH) in patients with and without a history of a fib treated with IV rt-PA and/or ET. Methods: Consecutive stroke code activations were retrospectively analyzed from January 2004-June 2020 at an academic comprehensive stroke center. Patients were included if they were treated with IV rt-PA and/or ET within 24 hours of stroke onset. Patients were stratified into the six groups:1-No hx of a fib with ET only, 2-Hx of a fib with ET only, 3-No hx of a fib with IV rt-PA plus ET, 4-Hx of a fib with IV rt-PA plus ET, 5-No hx of a fib with IV rt-PA only, 6-Hx of a fib with IV rt-PA only. Primary outcome was defined as any sICH within 72 hours of treatment using the NINDS definition. Baseline demographics were compared. Chi squared was used to assess differences in sICH rates and logistic regression to compare individual groups. Analyses were both unadjusted and adjusted for baseline NIHSS, age, sex, baseline blood pressure, pre-stroke mRS, smoking status, and baseline glucose. Results: We identified 720 AIS patients who received acute treatment (IV rt-PA: n=578; ET: n=100; IV rt-PA+ET:n=18). There was a significant difference in sex (p=0.005); Hispanic ethnicity (p=0.002); current smoking (p=<0.001); current alcohol use (p=0.03), CHF (p=0.01); and age (p<0.0001) between groups. Baseline NIHSS was significantly higher in Group 4 (23, SD 8, p=<0.001).In adjusted analysis, there was no significant difference in sICH in patients with a fib after receiving IVtPA (OR 1.53, CI 0.47-4.99, p=0.48), ET (OR 0.93 , CI 0-∞, p=1.00), or both (OR 0.25,CI 0.00-9.07, p=0.45) compared to those without afib. There was no significant difference in sICH in adjusted analyses in patients with and without a fib overall (OR 0.93, CI 0-∞, p=1.00). Conclusion: In this study, atrial fibrillation did not have a significant impact on rates of sICH in AIS patients treated with IV rt-PA, ET, or both. This study supports the safety of IV rt-PA, ET, and combination therapy in the atrial fibrillation population.

Background. Acute Ischemic Stroke (AIS) is a common cause of death worldwide and the leading cause of long-term severe disability. Endovascular bridging therapies (EBT), including endovascular thrombectomy (ET) and intra-arterial thrombolytic (IAT), have been recommended to realize a favorable functional outcome for AIS patients. Methods. An overview of meta-analyses of primary randomized controlled trial (RCT) studies was performed evaluating EBT for AIS patients compared with usual care. Results. Ten meta-analyses were included in this overview. ET was associated with a higher incidence of achieving functional outcome improvement, defined as a modified Rankin scale of 0 to 1 (mRS, p=0.003), 0 to 2 (p<0.00001), and 0 to 3 (p=0.005). The risk of symptomatic intracranial hemorrhage (sICH) rate and all-cause mortality were similar between the two groups. Moreover, IAT treatment was also related to significantly improved outcomes in terms of the mRS score (p<0.05), but no significant difference in rates of sICH and mortality within 90 days. Conclusions. In conclusion, our analysis supports that EBT, regardless of format (e.g., ET or IAT), is superior to the best medical therapy alone (e.g., IVT) in terms of mRS score in patients with AIS. In addition, the safety of EBT is similar to IVT.

Background and purposePrompt recanalization of cerebral arteries in patients diagnosed with acute ischemic stroke is known to be associated with a better clinical outcome. The aim of this study was to present our initial experience regarding the efficacy and safety of the Solitaire FR as a revascularization device.Methods56 consecutive patients presenting with acute ischemic stroke underwent intra-arterial therapy using the Solitaire FR revascularization device. Immediate angiographic results and early clinical outcomes are presented.ResultsSolitaire FR was successful in achieving recanalization in 50 out of 56 patients (89%) with a final Thrombolysis in Cerebral Infarction score ≥2b. Five out of 56 patients had procedure related complications: two asymptomatic subarachnoid hemorrhages, two thromboembolic events and one symptomatic intracranial hemorrhage (PH2). Thirty patients (53.5%) demonstrated at discharge a National Institutes of Health Stroke Scale Score of ≤1 or an improvement of at least 10 points from baseline, and 26 patients (46%) had a modified Rankin Score ≤2.ConclusionsSolitaire FR is successful in achieving a high rate of arterial recanalization with a low complication rate. The Solitaire FR is a promising thrombectomy tool with a high degree of effectiveness, safety and ease of use.

Abstract Background and purpose This study assessed the predictive factors for symptomatic intracranial hemorrhage (sICH) in patients with acute ischemic stroke (AIS) after receiving intravenous thrombolysis (IVT) within 6 h in northern China. Methods We retrospectively analyzed ischemic stroke patients who were treated with IVT between November 2016 and December 2018 in 19 hospitals in Shandong Province, China. Potential predictors of sICH were investigated using univariate and multivariate analyses. Results Of the 1293 enrolled patients (845 men, aged 62 ± 11 years), 33 (2.6%) developed sICH. The patients with sICH had increased coronary heart disease (36.4% vs. 13.7%, P = 0.001), more severe stroke (mean National Institutes of Health Stroke Scale [NIHSS] score on admission of 14 vs.7, P < 0.001), longer door-to-needle time [DNT] (66 min vs. 50 min, P < 0.001), higher blood glucose on admission, higher white blood cell counts (9000/mm3 vs. 7950/mm3, P = 0.004) and higher neutrophils ratios (73.4% vs. 67.2%, P = 0.006) et al. According to the results of multivariate analysis, the frequency of sICH was independently associated with the NIHSS score (OR = 3.38; 95%CI [1.50–7.63]; P = 0.003), DNT (OR = 4.52; 95%CI [1.69–12.12]; P = 0.003), and white blood cell count (OR = 3.59; 95%CI [1.50–8.61]; P = 0.004). When these three predictive factors were aggregated, compared with participants without any factors, the multi-adjusted odds ratios (95% confidence intervals) of sICH for persons concurrently having one, two or three of these factors were 2.28 (0.25–20.74), 15.37 (1.96–120.90) and 29.05 (3.13–270.11), respectively (P for linear trend < 0.001), compared with participants without any factors. Conclusion NIHSS scores higher than 10 on admission, a DNT > 50 min, and a white blood cell count ≥9000/mm3 were independent risk factors for sICH in Chinese patients within 6 h after IVT for AIS.

IntroductionThe direct aspiration first pass technique (ADAPT) has been introduced as a simple and fast method for achieving good angiographic and clinical outcomes using large bore aspiration catheters for the treatment of acute ischemic stroke (AIS). We present a single center's long term experience with ADAPT.MethodsRetrospective analysis of a database was gathered on patients undergoing stroke thrombectomy with ADAPT at a stroke center. Specific parameters captured included age, gender, National Institutes of Health Stroke Scale (NIHSS) score at presentation, time to presentation from last normal, and modified Rankin Scale (mRS) score at the 90 day follow-up. Radiological and angiographic imaging was reviewed to document the location of the vascular occlusion, Thrombolysis in Cerebral Infarction (TICI) flow postprocedure, and procedural complications.Results191 consecutive patients who suffered an AIS treated with ADAPT were reviewed; 91 were women, and mean age was 67 years. Patients presented with a mean NIHSS score of 15.4, and 71 patients received intravenous tissue plasminogen activator. The average time from onset to puncture was 7.8 h. The average time for recanalization was 37.3 min. TICI 2B or better recanalization was achieved in 180 (94.2%) patients. 98 (54.1%) patients had an mRS of 0–2 at 90 days. Direct aspiration alone was performed in 145 cases, and 43 cases required the additional use of a stent retriever. There was no significant difference in presenting NIHSS score, average time to presentation, average mRS at 90 days, or 90 day mortality between the two groups. Time to recanalization was 29.6 min for direct aspiration compared with 61.4 min in cases that required adjunct devices (p=0.00000201). 79 (57.7%) patients who underwent direct aspiration only achieved a good outcome at 90 days (mRS 0–2) compared with 19 (43.2%) who underwent adjunct therapies (p=0.12).ConclusionsADAPT is an effective method to achieve good clinical and angiographic outcomes, and serves as a useful firstline method for revascularization.

Background and purposePrevious studies have reported conflicting results as to whether women have poorer functional outcome than men after thrombolytic therapy. This study aims to investigate the relationship between sex differences and the prognosis of intravenous thrombolysis in Chinese patients with acute ischaemic stroke.MethodsThe patients enrolled in this study were from the Chinese Acute Ischemic Stroke Thrombolysis Monitoring and Registration study. The primary outcome was poor functional outcome, defined as a 3-month modified Rankin score of 3–6. The safe outcome was symptomatic intracranial haemorrhage (SICH) and mortality within 7 days and 90 days. Multiple Cox regression model was used to correct the potential covariates to evaluate the association between sex disparities and prognosis. Furthermore, the interaction of preonset Rankin scores, baseline National Institute of Health Stroke Scale (NIHSS) scores and Trial of Org 10172 in Acute Stroke Treatment (TOAST) types was statistically analysed.ResultsA total of 1440 patients were recruited, including 541 women and 899 men. The baseline information indicated that women were older at the time of onset (66.2±11.2 years vs 61.0±11.3 years, p<0.001), and more likely to have a history of atrial fibrillation (25.3% vs 11.2%, p<0.001), and had a higher NIHSS score on admission (12.3±6.8 vs 11.6±6.7, p=0.04). According to the prognosis analysis of unsatisfactory functional recovery, there was no significant difference between women and men (45.9% vs 37.1%; adjusted OR 1.01, 95% CI 0.75 to 1.37). As for the safe outcome, the proportion of SICH and mortality in women is relatively high but did not reach statistical significance. There was no significant interaction with sex, age, preonset Rankin score, NIHSS score, TOAST classification and the prognosis of intravenous thrombolysis.ConclusionsFor Chinese patients with ischaemic stroke, although women are older and more severe at the time of onset, the prognosis after intravenous thrombolysis is not significantly different from men.

ObjectiveTreatment of patients with stroke presenting with minor deficits remains controversial, and the recent Potential of rtPA for Ischemic Strokes with Mild Symptoms (PRISMS) trial, which randomized patients to thrombolysis vs aspirin, did not show benefit. We studied the safety and efficacy of thrombolysis in a population of patients with acute stroke presenting with low NIH Stroke Scale (NIHSS) scores screened using MRI.MethodsThe NIH Natural History of Stroke database was reviewed from January 2006 to December 2016 to identify all patients with an initial NIHSS score ≤5 who received thrombolysis within 4.5 hours of symptom onset after being screened with MRI. The 24-hour postthrombolysis MRIs were reviewed for hemorrhagic transformation. Primary outcomes were symptomatic intracranial hemorrhage (sICH) and favorable 90-day outcome modified Rankin Scale score 0–1. Subgroup analysis was performed on patients who would have been eligible for the PRISMS trial, which enrolled patients with a nondisabling neurologic deficit.ResultsA total of 121 patients were included in the study with a median age of 65 and an NIHSS score of 3; 63% were women. The rate of any hemorrhagic transformation was 13%, with 11% of them being limited to petechial hemorrhage. The rate of sICH was <1%. Sixty-six patients had 90-day outcome data; of those, 74% had a favorable outcome. For the subgroup of 81 PRISMS-eligible patients, none experienced sICH. Fifty of these patients had 90-day outcome data; of these, 84% had a favorable outcome.ConclusionsThrombolytic therapy was safe in our patients with stroke with minor deficits who were initially evaluated by MRI. Future studies of this population may benefit from MRI selection.Classification of evidenceThis study provides Class IV evidence that for patients with acute ischemic stroke and NIHSS ≤5 screened with MRI, IV tissue plasminogen activator is safe.

Abstract BACKGROUND: The promising results of the Solitaire Flow Restoration (FR) With the Intention for Thrombectomy (SWIFT) trial recently led to Food and Drug Administration (FDA) approval of the Solitaire FR stent retriever device for recanalization of cerebral vessels in patients with acute ischemic stroke. OBJECTIVE: To report the early postmarket experience with this device since its FDA approval in the United States, which has not been previously described. METHODS: We conducted a retrospective analysis of consecutive acute ischemic strokes cases treated between March 2012 and July 2012 at 10 United States centers where the Solitaire FR was used as a single device or in conjunction with other intraarterial endovascular approaches. RESULTS: A total of 101 patients were identified (mean age, 64.7 years; mean admission National Institutes of Health Stroke Scale [NIHSS] score, 17.6). Intravenous thrombolysis was administered in 39% of cases; other endovascular techniques were utilized in conjunction with the Solitaire FR in 52%. Successful recanalization (Thrombolysis in Myocardial Infarction 2/3) was achieved in 88%. The rate of symptomatic intracranial hemorrhage within the first 24 hours was 15%. In-hospital mortality was 26%. At 30 days, 38% of patients had favorable functional outcome (modified Rankin scale score ⩽2). Severity of NIHSS score on admission was a strong predictor of poor outcome. CONCLUSION: Our study shows that a variety of other endovascular approaches are used in conjunction with Solitaire FR in actual practice in the United States. Early postmarket results suggest that Solitaire FR is an effective tool for endovascular treatment of acute ischemic stroke.
