Background and purposeIn recent trials, acute ischemic stroke (AIS) from large artery occlusion (LAO) was resistant to intravenous thrombolysis and adjunctive stent retriever thrombectomy (SRT) was associated with better perfusion and outcomes. Despite benefit, 39–68% of patients had poor outcomes. Thrombectomy in AIS with LAO within 3 h is performed secondary to intravenous thrombolysis, which may be associated with delay. The purpose of our study is to evaluate the safety, feasibility, recanalization rate, and outcome of primary SRT within 3 h without intravenous thrombolysis in AIS from LAO.MethodsBased on an institutionally approved protocol, stroke patients with LAO within 3 h were offered primary SRT as an alternative to intravenous recombinant tissue plasminogen activator. Consecutive patients who underwent primary SRT for LAO within 3 h from 2012 to 2014 were enrolled. Outcomes were measured using the modified Rankin Scale (mRS).Results18 patients with LAO of mean age 62.83±15.32 years and median NIH Stroke Scale (NIHSS) score 16 (10–23) chose primary SRT after giving informed consent. Near complete (TICI 2b in 1 patient) or complete (TICI 3 in 17 patients) recanalization was observed in all patients. Time to recanalization from symptom onset and groin puncture was 188.5±82.7 and 64.61±40.14 min, respectively. NIHSS scores immediately after thrombectomy, at 24 h and 30 days were 4 (0–12), 1 (0–12), and 0 (0–4), respectively. Asymptomatic perfusion-related hemorrhage developed in four patients (22%). 90-day outcomes were mRS 0 in 50%, mRS 1 in 44.4%, and mRS 2 in 5.6%.ConclusionsOur study demonstrates that primary SRT in AIS from LAO is safe and feasible and is associated with complete recanalization and good outcome. Further study is required.

Abstract Background: Up to 30% of patients with mild ischemic stroke suffer neurologic deterioration. However, optimal medical approaches of such patients remain controversial given the efficacy and safety of intravenous thrombolysis (IVT). The purpose of this study was to evaluate whether patients with acute mild stroke stratified with ABCD2 score (the risk of stroke on basis of age, blood pressure, clinical features, duration of symptoms, and presence of diabetes mellitus) could benefit from IVT. Methods: Among 3321 patients with a final diagnosis of acute ischemic stroke, we retrospectively included 224 patients identified with acute mild neurologic deficits (National Institution of Health Stroke Scale, NIHSS ≤5) treated with or without IVT. Odds ratios (OR) with their confidence intervals (CI) for outcomes between groups were assessed by using multivariable binary logistic regression analyses. And the heterogeneity of treatment effect magnitude for excellent outcome at 90d (modified Rankin Scale [mRS] 0-1) was estimated in different subgroups. Results: A total of 224 cases were enrolled, 106 receiving IVT and 118 treated with secondary stroke prevention strategies alone. At 7d, 30 (28.3%) patients with IVT treatment versus 16 (13.6%) patients not receiving IVT achieved significant improvement (≥4-point NIHSS score decrease or complete resolution; OR, 2.448; 95%CI, 1.204-4.977; P=0.013). At 90d, excellent outcome was achieved in 83 (78.3%) patients treated with IVT versus 77 (65.35%) patients without IVT treatment (OR, 3.156; 95%CI, 1.526-6.528; P=0.002), especially in those with ABCD2 score ≥5 (OR, 2.768; 95%CI, 1.196-6.406; P=0.017) and with stroke subtype of large artery atherosclerosis (OR, 5.616; 95%CI, 1.080-29.210; P=0.040). Besides, 7(6.6%) IVT-treated patients versus 2 (1.7%) non-IVT-treated patients developed intracranial hemorrhage (ICH; P=0.359), among these only 1 (0.9%) was symptomatic ICH in IVT group. Conclusions: For acute mild ischemic stroke patients, we reassured the safety and especially the efficacy of IVT at 7- and 90-days. Patients with 5 or more of ABCD2 score and stroke subtype of large artery atherosclerosis might benefit more from IVT.

Intravenous thrombolysis (IVT) in patients with a low National Institutes of Health Stroke Scale (NIHSS) score of 0–5 remains controversial. IVT should be used in patients with mild but nevertheless disabling symptoms. We hypothesize that response to IVT of patients with “mild stroke” may depend on their level of functional dependence (FD) at hospital admission. The aims of our study were to investigate the effect of IVT and to explore the role of FD in influencing the response to IVT. This study was a retrospective analysis of a prospectively collected database, including 389 patients stratified into patients receiving IVT (IVT+) and not receiving IVT (IVT −) just because of mild symptoms. Barthel index (BI) at admission was used to assess FD, dividing subjects with BI score < 80 (FD+) and with BI score ≥ 80 (FD−). The efficacy endpoints were the rate of positive disability outcome (DO+) (3-month mRS score of 0 or 1), and the rate of positive functional outcome (FO+) (mRS score of zero or one, plus BI score of 95 or 100 at 3 months). At the multivariate analysis, IVT treatment was an independent predictor of DO+ (OR 3.12, 95% CI 1.34−7.27, p = 0.008) and FO+ (OR: 4.70, 95% CI 2.38−9.26, p = 0.001). However, FD+ IVT+ patients had a significantly higher prevalence of DO+ and FO+ than those FD+ IVT–. Differently, IVT treatment did not influence DO+ and FO+ in FD– patients. In FD+ patients, IVT treatment represented the strongest independent predictor of DO+ (OR 6.01, 95% CI 2.59–13.92, p = 0.001) and FO+ (OR 4.73, 95% CI 2.29–9.76, p = 0.001). In conclusion, alteplase seems to improve functional outcome in patients with “mild stroke”. However, in our experience, this beneficial effect is strongly influenced by FD at admission.

Introduction: To evaluate overall ischemic stroke rates, specific subtypes, and clinical presentation during the COVID-19 pandemic in a multicenter observational study from eight states across US. Methods: We compared all ischemic strokes admitted between January 2019 and May 2020, grouped as; March-May 2020 (COVID-19 period), March-May 2019 (seasonal pre-COVID period) and November 2019-January 2020 (immediate pre-COVID-19 period). Primary outcome was stroke severity at admission measured by NIHSS stratified as mild (0-7), moderate (8-14), and severe (>14) symptoms. Secondary outcomes were number of large vessel occlusions (LVOs), stroke etiology, IV-tPA rates, and disposition. Results: Of the 7,969 patients diagnosed with acute stroke during the study period, 933 (12%) presented in the COVID-19 period, 1319 (17%), and 1254 (16%) presented in the seasonal pre-COVID-19 and immediate pre-COVID-19 periods, respectively. Significant decline was observed in the weekly mean volume of newly diagnosed strokes (98±7.3 vs 50±20, p<0.01 and 95±10.5 vs 50±20, p<0.01), LVOs (16.5±3.8 vs 8.3±5.9, p<0.01 and 14.3± 4.5 vs 8.3±5.9, p<0.01), and IV-tPA (5.3±2.9 vs 10.9±3.4 and 12.7±4.1, p<0.01). Mean weekly proportion of LVOs remained the same, when compared with seasonal pre-COVID-19 period (18%±5 vs 16%±7, p=0.24) and immediate pre-COVID-19 period (17.4%±4 vs. 16%±7, p=0.32). Additionally, these patients presented with less severe disease (NIHSS<14; aOR: 0.63, 95%CI: 0.41-0.97, p=0.035) during the COVID-19 period as compared to immediate pre-COVID-19 period. Conclusions: We observed a decrease in newly diagnosed stroke cases and rates of IV-tPA administration, while the LVO frequency remained unchanged during the COVID-19 pandemic. Additionally, these stroke patients had more severe presentations.

PurposeTo investigate the efficacy and safety of the Trevo ProVue (TPV) stent retriever in stroke patients with large artery occlusions, with particular attention to the full structural radiopacity of the TPV.Materials and methodsCase files and images of TPV treatments were reviewed for clinical and technical outcome data, including revascularization rates, device and procedure related complications, and outcome at discharge and after 90 days.Results76 patients were treated with TPV. Mean National Institutes of Health Stroke Scale (NIHSS) score was 18 and 68% had additional intravenous thrombolysis. 63 occlusions were in the anterior circulation: 44 M1 (58%), 8 M2 (11%), 8 internal carotid artery-terminus (11%), 2 internal carotid artery- left (3%), 1 A2 (1%), and 13 vertebrobasilar (17%). 58 of 76 (76%) were solely treated with TPV; the remainder were treated with additional stent retrievers. Mean number of passes in TPV only cases was 2.2 (SD 1.2). In rescue cases, 3.2 (SD 2.2) passes were attempted with the TPV followed by 2.6 rescue device passes (SD 2). TPV related adverse events occurred in 4/76 cases (5%) and procedural events in 6/76 cases (8%). Mean procedural duration was 64 min (SD 42). Thrombolysis in Cerebral Infarction (TICI) 2b/3 recanalization was achieved in 69/76 patients (91%), including 50% TICI 3. Of 56 survivors (74%), 37 (49%) showed a favorable outcome at 90 days (Solitaire With the Intention for Thrombectomy trial criteria), statistically associated with age, baseline NIHSS, onset to revascularization time, and TICI 2b–3 reperfusion. TPV radiopacity allowed for visual feedback, changing the methodology of stent retriever use in 44/76 cases (58%).ConclusionsNeurothrombectomy with TPV is feasible, effective, and safe. The recanalization rate compares favorably with reported data in the literature. Improved structural radiopacity may facilitate neurothrombectomy or influence the course of action during retrieval.

More than 50% of all patients with ischemic stroke initially present with mild symptoms. Despite the mild clinical presentation, a high percentage of these patients develop stroke progression with consequent disability, recurrent stroke, or death at follow-up. Intravenous thrombolysis with recombinant tissue plasminogen activator within 4.5 hours has been proven to be an effective treatment for acute ischemic stroke, but the risk-benefit ratio of this therapeutic approach remains still unclear in patients with mild stroke. Many patients with mild stroke are frequently excluded from thrombolysis. Large artery occlusion is an important predictor of early neurological deterioration or poor outcomes in patients with mild ischemic stroke. However, current guidelines do not recommend endovascular thrombectomy in patients with National Institutes of Health Stroke Scale score of <6 points. Some previous retrospective cohort studies have reported that endovascular thrombectomy showed promising results in cases of acute mild ischemic stroke with large vessel occlusion. Treatment decisions in patients with mild ischemic stroke should be individualized depending on clinical and radiological features. In this review, we discuss the prognosis of mild strokes, efficacy of intravenous thrombolysis and endovascular thrombectomy, and the role of neurovascular imaging in treatment decision making in this patient population.

Objectives: Thrombolysis treatment for patients with mild stroke is controversial. The aim of this study is to investigate whether patients with mild stroke or its specific etiologic subtype could benefit from recombinant tissue plasminogen activator (rt-PA) therapy. Methods: Data were derived from two cohorts of patients with and without rt-PA treatment: (1) the Thrombolysis Implementation and Monitor of Acute Ischemic Stroke in China database and (2) the China National Stroke Registry database. Patients with mild stroke (defined as National Institutes of Health Stroke Scale≤5) receiving the rt-PA therapy and without rt-PA therapy were matched in 1:2 for age, sex, stroke severity and etiologic subtype. Good functional outcome was defined as modified Rankin Scale 0-1 at 3 months. Odds ratios (ORs) with 95 % confidence intervals (CIs) were estimated using conditional logistic regression in total patients and by etiologic subtype, respectively. Results: A total of 134 rt-PA treated patients were matched to 249 non-rt-PA treated patients in the study. Among them, 104 (76%) rt-PA-treated patients with mild stroke had good outcome after 3 months compared with 173 (69.5%) non-rt-PA-treated matching cases (odds ratio [OR], 1.48; 95% confidence interval [CI], 0.91-2.43; P=0.12). Compared with non-rt-PA treatment group, rt-PA-treated patients had good outcome after 3 months in those with stroke subtype of large-artery atherosclerosis (LAA) (80.5% vs 65.1%; OR, 2.19; 95%CI, 1.14-4.21; P=0.02). Conclusions: For patients with mild stroke, intravenous rt-PA treatment may be effective. Patients with stroke subtype of LAA could benefit more from intravenous rt-PA treatment.

Objective: The term ‘mild stroke’ is used to describe stroke patients with a NIHSS score of 0 to 6. There is still no clear decision regarding the application of iv recombinant tissue plasminogen activator (iv-tPA) to patients who is admitted with an acute ischemic stroke and is in the mild stroke category. In our study, we aimed to analyze the data of patients who applied to our stroke center with an acute mild stroke clinic and received iv-tPA treatment and their three-month follow-up. Methods: A total of 47 (age 69.1 ± 14.1, 28 female) mild stroke patients were included out of 350 patients receiving thrombolytic therapy. Intravenous thrombolysis was initiated with a maximum delay of 4.5 hours in all patients. Patients had a NIHS score less than 6. NIHSS scores immediately before starting thrombolytic therapy and scores 24 hours after treatment were recorded. Modified Rankin Scale scores (mRS) at admission, 1 and 3 months were recorded. Results: NIHSS scores of the patients who received tPA decreased significantly after the treatment (p = 0.001). The patients’ 1st and 3rd month mRS scores were statistically significantly decreased according to the mRS scores when they entered the treatment (p = 0.001). Conclusions: This study highlights the efficacy of iv-tPA in acute ischemic stroke patients with mild symptoms and demonstrates the low risk profile of this therapy.

Objective: We investigated whether intravenous thrombolysis (IVT) affected the outcomes and complications of mechanical thrombectomy (MT), specifically focusing on thrombus fragmentation. Methods: The patients who underwent MT for large artery occlusion (LAO) were classified into two groups: MT with prior IVT (MT+IVT) group and MT without prior IVT (MT-IVT) group. The clinical outcome, successful recanalization with other radiological outcomes, and complications were compared, between two groups. Subgroup analysis was also performed for patients with simultaneous application of stent retriever and aspiration. Results: There were no significant differences in clinical outcome and successful recanalization rate, between both groups. However, the ratio of pre- to peri-procedural thrombus fragmentation was significantly higher in the MT+IVT group (14.6% and 16.2%, respectively; P=0.004) compared to the MT-IVT group (5.1% and 6.8%, respectively; P=0.008). The MT+IVT group required more second stent retriever (16.2%), more stent passages (median value = 2), and more occurrence of distal emboli (3.9%) than the MT-IVT group (7.9%, median value = 1, and 8.1%, respectively) (P=0.004, 0.008 and 0.018, respectively). In subgroup analysis, the results were similar to those of the entire patients. Conclusion: Thrombus fragmentation of IVT with t-PA before MT resulted in an increased need for additional rescue therapies, and it could induce more distal emboli. The use of IVT prior to MT does not affect the clinical outcome and successful recanalization, compared with MT without prior IVT. Therefore, we need to reconsider the need for IVT before MT.
