Abstract Purpose It is unclear whether stroke patients undergoing endovascular thrombectomy (EVT) should receive bridging intravenous thrombolysis (IVT), if eligible. This study aims at analyzing the impact of bridging IVT on short-term clinical outcome. Methods In a prospective regional stroke registry, all stroke patients with premorbid modified Rankin Scale (mRS) score of 0–2 who were admitted within 4.5 h after onset and treated with EVT were analyzed retrospectively. Patients receiving “IVT prior to EVT” (IVEVT) were compared to those undergoing “EVT only” regarding the ratio of good outcome, discharge mRS, mRS shift, hospital mortality, and occurrence of symptomatic intracranial hemorrhage. Results In total, 2022 patients were included, 816 patients (40.4%) achieved good clinical outcome; 1293 patients (63.9%) received bridging IVT. There was no significant difference between both groups regarding the ratio of good outcome (IVEVT 41.4% vs. EVT 38.5%, P = 0.231), discharge mRS (median, IVEVT 3 vs. EVT 3, P = 0.178), mRS shift (median, IVEVT 3 vs. EVT 3, P = 0.960), and hospital mortality (IVEVT 19.3% vs. EVT 19.5%, P = 0.984). Bridging IVT was not a predictor of outcome (adjusted OR 1.00, 95% CI 0.79–1.26, P = 0.979). However, it was an independent predictor of symptomatic intracranial hemorrhage (adjusted OR 1.79, 95% CI 1.21–2.72, P = 0.005). Conclusions The results of the present study suggest that bridging IVT does not seem to improve short-term clinical outcome of patients undergoing EVT. Nonetheless, there might be a subgroup of patients that benefits from IVT. This needs to be addressed in randomized controlled trials.

Introduction : BAO (basilar artery occlusion) is well known by catastrophic outcomes whether death or disability in approximately 70 %. 1 Thrombectomy as an intervention in large vessel occlusion of anterior proximal circulation was approved after multiple RCTs and meta‐analyses. 2 In spite of two RCTs that appeared lately, there is still uncertainty about the effect of thrombectomy in BAO. 9, 10 Our study aims to report the outcome of BAO, as a further clue of MT effectiveness in BAO and variables affecting good outcome and mortality rate. Methods : We retrospectively collected the clinical and radiological data of 30 BAO patients treated in our center between 2016 and 2020. There is no limitation as regard age or presenting NIHHS. Twenty‐two patients who came to the emergency within 4.5 hours had I.V. thrombolytic therapy (73.3%). A favorable clinical outcome was considered if mRS ≤ 2. Angioplasty, stenting, or I.A thrombolysis were used as a rescue treatment. Symptomatic intracranial hemorrhage within two days after the initiation of treatment and mortality at 90 days were reported. The radiological outcome was assessed by modified Thrombolysis in Cerebral Infarction (mTICI) score where mTICI ≥ 2b or 3 at the end of the intervention was considered a favorable radiological result. Multiple variables were tested for their effect on favorable clinical outcomes and mortality (Table 1). Results : Among 30 patients, the mean age was 61.23 ± 16.81 years; 20/30 (66.7%) male. A favorable functional outcome was achieved in (40.7%). Successful revascularization was achieved in 26 patients (86.7 %). Four patients had procedural complications (13.3%). Symptomatic intracranial hemorrhage occurred in three cases (11%) and mortality at 90 days was 11 patients (36.7 %). The presenting NIHSS is the only predictor of mortality and the optimal cut‐off value for death was 15 with AUC = 0.758 (sensitivity 91 % and specificity 59%) and p‐value = 0.02. TOR (time of onset to recanalization) had no effect on the clinical outcome which is controversy with the paradigm of early reperfusion leading to a good outcome Conclusions : In spite of two RCSs approved no statistical difference between medical treatment and thrombectomy, thrombectomy is still an effective procedure in real‐world practice in selected cases. The presenting NIHSS is the only predictor of mortality in our studies. More studies are warranted to discover other predictors of BAO thrombectomy outcome to improve case selection and avoid futile recanalization.

Objectives: Telestroke is the application of telemedicine to stroke care. We estimated the effect of participation in a telestroke network on in-hospital mortality in the state of Georgia, and explored its impact on mitigating the difference in mortality for patients admitted in nighttime compared to those admitted in daytime. Methods: We selected patients with ischemic stroke from 15 non-teaching hospitals in the Georgia’s Paul Coverdell Acute Stroke Registry from 2005 to 2016. We applied a quasi-experimental study design by classifying patients from 4 hospitals that participated in a telestroke network in 2009 as the treatment group, and patients from 11 hospitals that were not covered by the telestroke network as the comparison group. All selected hospitals are located in non-Metropolitan Areas. We compared mortality between treatment and comparison groups in 2005 - 2008 (pre-participation period for treatment group) and in 2009 - 2016 (post-participation period for treatment group), and estimated difference in in-hospital mortality attributable to participation in a telestroke network by applying a difference-in-differences approach, while adjusting for patients’ age, sex, race/ethnicity, insurance coverage, arrival mode, ambulatory status prior to the current stroke, stroke severity, medical history of atrial fibrillation/flutter and hospital admission time. Results: The mortality among ischemic stroke patients decreased in all selected hospitals over the last decade. Participation in a telestroke network significantly decreased in-hospital mortality by 3.2% (p-value= 0.003). There was a positive association between nighttime admission and in-hospital mortality in the entire patient sample. After controlling for the effect of participation in a telestroke network, the nighttime effect on mortality still remained significant (odds ratio=1.25, 95% confidence interval: 1.10 - 1.42). Conclusions: Acute ischemic stroke patients admitted in hospitals participating in a telestroke program had a more pronounced reduction in in-hospital mortality. However, telestroke coverage did not alter the effect of nighttime admission on in-hospital mortality.

Abstract Purpose In mechanical thrombectomy, it has been hypothesized that multiple retrieval attempts might the improve reperfusion rate but not the clinical outcome. In order to assess a potential harmful effect of a mechanical thrombectomy on patient outcome, the number of retrieval attempts was analyzed. Only patients with a thrombolysis in cerebral infarction (TICI) score of 0 were reviewed to exclude the impact of eventual successful reperfusion on the mechanical hazardousness of repeated retrievals. Methods In this study 6635 patients who underwent endovascular thrombectomy (EVT) for acute large vessel occlusion (LVO) from the prospectively administered multicenter German Stroke Registry were screened. Insufficient reperfusion was defined as no reperfusion (TICI score of 0), whereas a primary outcome was defined as functional independence (modified Rankin scale [mRS] 0–2 at day 90). Propensity score matching and multivariable logistic regressions were then performed to adjust for confounders. Results A total of 377 patients (7.8%) had a final TICI score of 0 and were included in the study. After propensity score matching functional independence was found to be significantly more frequent in patients who underwent ≤ 2 retrieval attempts (14%), compared to patients with > 2 retrieval attempts (3.9%, OR 0.29, 95% CI 0.07–0.73, p = 0.009). After adjusting for age, sex, admission NIHSS score, and location of occlusion, more than two retrieval attempts remained significantly associated with lower odds of functional independence at 90 days (OR 0.2, 95% CI 0.07–0.52, p = 0.002). Conclusion In patients with failure of reperfusion, more than two retrieval attempts were associated with a worse clinical outcome, therefore indicating a possible harmful effect of multiple retrieval attempts.

Fluid Attenuated Inversion Recovery

Background and Purpose: We investigated whether the signal change on fluid-attenuated inversion recovery (FLAIR) can serve as a tissue clock that predicts the clinical outcome after endovascular thrombectomy (EVT), independently of the onset-to-admission time. Methods: Consecutive patients with acute stroke treated with EVT between September 2014 and December 2018 were enrolled. Based on the parenchymal signal change on FLAIR, patients were classified into FLAIR-negative and FLAIR-positive groups. The clinical characteristics, imaging findings, EVT parameters, and the intracranial hemorrhage defined as Heidelberg Bleeding Classification ≥1c hemorrhage (parenchymal hemorrhage, intraventricular hemorrhage, subarachnoid hemorrhage, and/or subdural hemorrhage) were compared between the 2 groups. A modified Rankin Scale score 0 to 1 at 3 months was considered to represent a good outcome. Results: Of the 227 patients with EVT during the study period, 140 patients (62%) were classified into the FLAIR-negative group and 87 (38%) were classified into the FLAIR-positive group. In the FLAIR-negative group, the patients were older ( P =0.011), the onset-to-image time was shorter ( P <0.001), the frequency of cardioembolic stroke was higher ( P =0.006), and the rate of intravenous thrombolysis was higher ( P <0.001) in comparison to the FLAIR-positive group. Although the rate of complete recanalization after EVT did not differ between the 2 groups ( P =0.173), the frequency of both any-intracranial hemorrhage and Heidelberg Bleeding Classification ≥1c hemorrhage were higher in the FLAIR-positive group ( P =0.004 and 0.011). At 3 months, the percentage of patients with a good outcome (FLAIR-negative, 41%; FLAIR-positive, 27%) was significantly related to the FLAIR signal change ( P =0.047), while the onset-to-image time was not significant ( P =0.271). A multivariate regression analysis showed that a FLAIR-negative status was independently associated with a good outcome (odds ratio, 2.10 [95% CI, 1.02–4.31], P =0.044). Conclusions: A FLAIR-negative status may predict the clinical outcome more accurately than the onset-to-admission time, which may support the role of FLAIR as a tissue clock.

Background Acute ischemic stroke patients with a large-vessel occlusion but mild symptoms (NIHSS ≤ 6) pose a treatment dilemma between medical management and endovascular thrombectomy. Aims To evaluate the differences in clinical outcomes of endovascular thrombectomy-eligible patients with target-mismatch perfusion profiles who undergo either medical management or endovascular thrombectomy. Methods Forty-seven patients with acute ischemic stroke due to large-vessel occlusion, NIHSS ≤ 6, and a target-mismatch perfusion imaging profile were included. Patients underwent medical management or endovascular thrombectomy following treating neurointerventionalist and neurologist consensus. The primary outcome measure was NIHSS shift. Secondary outcome measures were symptomatic intracranial hemorrhage, in-hospital mortality, and 90-day mRS scores. The primary intention-to-treat and as-treated analyses were compared to determine the impact of crossover patient allocation on study outcome measures. Results Forty-seven patients were included. Thirty underwent medical management (64%) and 17 underwent endovascular thrombectomy (36%). Three medical management patients underwent endovascular thrombectomy due to early clinical deterioration. Presentation NIHSS ( P = 0.82), NIHSS shift ( P = 0.62), and 90-day functional independence (mRS 0–2; P = 0.25) were similar between groups. Endovascular thrombectomy patients demonstrated an increased overall rate of intracranial hemorrhage (35.3% vs. 10.0%; P = 0.04), but symptomatic intracranial hemorrhage was similar between groups ( P = 0.25). In-hospital mortality was similar between groups ( P = 0.46), though all two deaths in the medical management group occurred among crossover patients. Endovascular thrombectomy patients demonstrated a longer length of stay (7.6 ± 7.2 vs. 4.3 ± 3.9 days; P = 0.04) and a higher frequency of unfavorable discharge to a skilled-nursing facility ( P = 0.03) rather than home ( P = 0.05). Conclusions Endovascular thrombectomy may pose an unfavorable risk-benefit profile over medical management for endovascular thrombectomy-eligible acute ischemic stroke patients with mild symptoms, which warrants a randomized trial in this subpopulation.

Background Guidelines recommend against the use of intravenous tPA (tissue-type plasminogen activator; IV tPA) in acute ischemic stroke patients with prior ischemic stroke within 3 months. However, there are limited data on the safety of IV tPA in this population. Methods and Results A retrospective observational study of patients ≥66 years of age linked to Medicare claims and treated with IV tPA at Get With The Guidelines–Stroke hospitals (February 2009 to December 2015). We identified 293 patients treated with IV tPA who had a prior ischemic stroke within 3 months and 30 655 with no history of stroke. Patients with prior stroke had a higher stroke severity (median National Institutes of Health Stroke Scale, 11 [6–19] versus 11 [6–18]; absolute standardized difference, 11.2%) and a higher prevalence of cardiovascular comorbidities. Patients with prior stroke had a higher unadjusted risk for symptomatic intracranial hemorrhage (7.7% versus 4.8%) and in-hospital mortality (12.6% versus 8.9%), but these differences were not statistically significant after adjustment. When stratified by prespecified time epochs, the elevated risk for symptomatic intracranial hemorrhage was seen only within the first 14 days (16.3% versus 4.8%; adjusted odds ratio [aOR], 3.7 [95% CI, 1.62–8.43]) but not in other epochs (2.1% versus 4.8%; aOR, 0.38 [95% CI, 0.05–2.79] for 15–30 days and 7.4% versus 4.8%; aOR, 1.36 [95% CI, 0.77–2.40] for 31–90 days). In addition, patients with prior stroke were significantly more likely to have a combined outcome of in-hospital mortality or discharge to hospice (25.9% versus 17.0%; aOR, 1.70 [95% CI, 1.21–2.38]), less likely to be discharged to home (28.3% versus 32.3%; aOR, 0.72 [95% CI, 0.54–0.98]), or to have good functional outcomes at discharge (modified Rankin Scale, 0–1; 11.3% versus 20.0%; aOR, 0.46 [95% CI, 0.24–0.89]). Conclusions Stroke providers need to continue to be vigilant about the safety of IV tPA in patients with prior stroke, particularly those with an event in the previous 14 days.

Objective: Mild stroke has traditionally been excluded from thrombolytic treatment trials and only few series have reported outcomes after IV rtPA in this group. The objectives of this study are to determine the proportion of mild stroke patients treated with IV rtPA and evaluate complications and short-term outcomes in this population. Methods: We analyzed patients in the Get With The Guidelines-Stroke registry that arrived within 4.5 hours from symptom onset with a mild ischemic stroke defined as a baseline NIHSS ≤5 who received IV rtPA between May 2010 and October 2012. The following outcomes and complications were analyzed: in-hospital mortality, home discharge, independent ambulation, length of stay (LOS), in-hospital death, and symptomatic intracranial hemorrhage (sICH) <36 h. Multivariable analysis was performed for predictors of outcomes and complications. Results: Of 147,917 patients who arrived <4.5 hours, 39,821 were treated with IV rtPA, of whom 8,243 (20.7%) had an NIHSS ≤5. We analyzed 5,910 treated patients with NIHSS ≤5 and complete data. The mean baseline NIHSS was 3.5 (median 4); 98.2% arrived within 3 hours and 78.6% were treated within 3 hours. Outcomes and predictors of worse outcome are described in the table. There was no difference in short-term outcomes amongst those treated at 0-3 vs. 3-4.5 hours. Conclusions: A sizeable minority of ischemic stroke patients treated with IV rtPA have a NIHSS ≤5. sICH occurred at a low rate of 1.8% and about 30% of these patients were unable to return home and could not ambulate independently. Longer-term outcomes are needed to define predictors of poor outcome in this population and which patients may benefit most from treatment.

Background and Purpose: Clinical outcome and mortality after endovascular thrombectomy (EVT) in patients with ischemic stroke are commonly assessed after 3 months. In patients with acute kidney injury (AKI), unfavorable results for 3-month mortality have been reported. However, data on the in-hospital mortality after EVT in this population are sparse. In the present study, we assessed whether AKI impacts in-hospital and 3-month mortality in patients undergoing EVT.Materials and Methods: From a prospectively recruiting database, consecutive acute ischemic stroke patients receiving EVT between 2010 and 2018 due to acute large vessel occlusion were included. Post-contrast AKI (PC-AKI) was defined as an increase of baseline creatinine of ≥0.5 mg/dL or &gt;25% within 48 h after the first measurement at admission. Adjusting for potential confounders, associations between PC-AKI and mortality after stroke were tested in univariate and multivariate logistic regression models.Results: One thousand one hundred sixty-nine patients were included; 166 of them (14.2%) died during the acute hospital stay. Criteria for PC-AKI were met by 29 patients (2.5%). Presence of PC-AKI was associated with a significantly higher risk of in-hospital mortality in multivariate analysis [odds ratio (OR) = 2.87, 95% confidence interval (CI) = 1.16–7.13, p = 0.023]. Furthermore, factors associated with in-hospital mortality encompassed higher age (OR = 1.03, 95% CI = 1.01–1.04, p = 0.002), stroke severity (OR = 1.05, 95% CI = 1.03–1.08, p &lt; 0.001), symptomatic intracerebral hemorrhage (OR = 3.20, 95% CI = 1.69–6.04, p &lt; 0.001), posterior circulation stroke (OR = 2.85, 95% CI = 1.72–4.71, p &lt; 0.001), and failed recanalization (OR = 2.00, 95% CI = 1.35–3.00, p = 0.001).Conclusion: PC-AKI is rare after EVT but represents an important risk factor for in-hospital mortality and for mortality within 3 months after hospital discharge. Preventing PC-AKI after EVT may represent an important and potentially lifesaving effort in future daily clinical practice.

Objective:To explore the association between blood pressure (BP) levels after endovascular thrombectomy (EVT) and the clinical outcomes of acute ischemic stroke (AIS) patients with large vessel occlusion (LVO).Methods:A study was eligible if it enrolled AIS patients older than 18 years, with an LVO treated with either successful or unsuccessful EVT, and provided either individual or mean 24-hour systolic BP values after the end of the EVT procedure. Individual patient data from all studies were analyzed using a generalized linear mixed-effects model.Results:A total of 5874 patients (mean age: 69±14 years, 50% women, median NIHSS on admission: 16) from 7 published studies were included. Increasing mean systolic BP levels per 10 mm Hg during the first 24 hours after the end of the EVT were associated with a lower odds of functional improvement (unadjusted common OR=0.82, 95%CI:0.80-0.85; adjusted common OR=0.88, 95%CI:0.84-0.93) and modified Ranking Scale score≤2 (unadjusted OR=0.82, 95%CI:0.79-0.85; adjusted OR=0.87, 95%CI:0.82-0.93), and a higher odds of all-cause mortality (unadjusted OR=1.18, 95%CI:1.13-1.24; adjusted OR=1.15, 95%CI:1.06-1.23) at 3 months. Higher 24-hour mean systolic BP levels were also associated with an increased likelihood of early neurological deterioration (unadjusted OR=1.14, 95%CI:1.07-1.21; adjusted OR=1.14, 95%CI:1.03-1.24) and a higher odds of symptomatic intracranial hemorrhage (unadjusted OR=1.20, 95%CI:1.09-1.29; adjusted OR=1.20, 95%CI:1.03-1.38) after EVT.Conclusion:Increased mean systolic BP levels in the first 24 hours after EVT are independently associated with a higher odds of symptomatic intracranial hemorrhage, early neurological deterioration, three-month mortality, and worse three-month functional outcomes.
