Symptomatic Intracranial Hemorrhage

Background and Purpose— The use of oral anticoagulants (OAC) is considered a contra-indication for intravenous thrombolytics as acute treatment of ischemic stroke. However, little is known about the risks and benefits of endovascular treatment in patients on prior OAC. We aim to compare outcomes after endovascular treatment between patients with and without prior use of OAC. Methods— Data of patients with acute ischemic stroke caused by an intracranial anterior circulation occlusion, included in the nationwide, prospective, MR CLEAN Registry between March 2014 and November 2017, were analyzed. Outcomes of interest included symptomatic intracranial hemorrhage and functional outcome at 90 days (modified Rankin Scale score). Outcomes between groups were compared with (ordinal) logistic regression analyses, adjusted for prognostic factors. Results— Three thousand one hundred sixty-two patients were included in this study, of whom 502 (16%) used OAC. There was no significant difference in the occurrence of symptomatic intracranial hemorrhage between patients with and without prior OACs (5% versus 6%; adjusted odds ratio, 0.63 [95% CI, 0.38–1.06]). Patients on OACs had worse functional outcomes than patients without OACs (common odds ratio, 0.57 [95% CI, 0.47–0.66]). However, this observed difference in functional outcome disappeared after adjustment for prognostic factors (adjusted common odds ratio, 0.91 [95% CI, 0.74–1.13]). Conclusions— Prior OAC use in patients treated with endovascular treatment for ischemic stroke is not associated with an increased risk of symptomatic intracranial hemorrhage or worse functional outcome compared with no prior OAC use. Therefore, prior OAC use should not be a contra-indication for endovascular treatment.

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.

Favorable Clinical Outcome

Background Limited observational data are available on endovascular treatment in acute ischemic stroke due to cervical artery dissection. Three studies comparing endovascular treatment with standard medical therapy or intravenous thrombolysis in cervical artery dissection-related acute ischemic stroke did not demonstrate superiority of endovascular treatment. Efficacy and the choice of endovascular treatment technique in this setting remain to be established. Aims To assess the potential efficacy and safety of endovascular treatment compared to intravenous thrombolysis alone or to no revascularization treatment in our center. Methods We selected all consecutive patients with cervical artery dissection-related acute ischemic stroke and intracranial occlusion from the Acute STroke Registry and Analysis of Lausanne between 2003 and 2017. We compared clinical and neuroimaging data of patients treated by endovascular treatment versus patients receiving intravenous thrombolysis or patients without revascularization treatment. Safety analysis included symptomatic intracranial hemorrhage, major radiological hemorrhages (parenchymal hematoma 1, parenchymal hematoma 2, and subarachnoid hemorrhage) and mortality within seven days. We assessed favorable clinical outcome (modified Rankin Scale 0-2) at three months using a binary logistic regression model. Results Of the 109 patients included, 24 had endovascular treatment, 38 received intravenous thrombolysis alone, and 47 had no revascularization treatment. Endovascular treatment patients had a higher rate of recanalization at 24 h. Major radiological hemorrhages occurred more often in endovascular treatment patients (all with bridging therapy) than in patients without revascularization treatment (p = 0.026), with no differences in symptomatic intracranial hemorrhage or mortality within seven days. Favorable clinical outcome at three months did not differ between groups (endovascular treatment versus intravenous thrombolysis p = 0.407; endovascular treatment versus no revascularization treatment p = 0.580). Conclusions In this single-center cohort of cervical artery dissection-related acute ischemic stroke with intracranial occlusion, endovascular treatment with prior intravenous thrombolysis may increase the risk of major radiological but not symptomatic intracranial hemorrhage. Despite the lack of clear superiority in our cohort, endovascular treatment should currently not be withheld in these patients.

<b><i>Objective:</i></b> The purpose of this meta-analysis is to evaluate the safety and efficacy of tirofiban during endovascular treatment (EVT) for acute ischemic stroke (AIS) patients. <b><i>Methods:</i></b> We systematically searched PubMed, Embase, Web of Science, and CENTRAL (Cochrane Central Register of Controlled Trials) databases for randomized controlled trials and cohort studies (published before May 1, 2020; no language restrictions) comparing tirofiban administration to blank control during EVT in patients with AIS. Our primary end points were the 3-month functional outcome, recanalization rate, symptomatic intracerebral hemorrhage, and 3-month mortality. <b><i>Results:</i></b> The incidence of 3-month modified Rankin Scale (mRS) 0–2 score of the tirofiban group was higher than that of the control group (odds ratio [OR] = 1.27, 95% CI [1.09, 1.48], <i>p</i> = 0.002) with heterogeneity (<i>I</i><sup>2</sup> = 34%, <i>p</i> = 0.11). Data pooled from the 6 studies describing the details of retriever stent in EVT revealed that tirofiban was associated with higher incidence of 3-month mRS 0–2 score (OR = 1.48, 95% CI [1.11, 1.96], <i>p</i> = 0.007). The recanalization rate was higher in the tirofiban group compared to the control group (OR = 1.66, 95% CI [1.16, 2.39], <i>p</i> = 0.006). There were no statistically significant differences in the incidence of symptomatic intracranial hemorrhage (OR = 0.97, 95% CI [0.73, 1.31], <i>p</i> = 0.86) and intracranial hemorrhage (OR = 1.08, 95% CI [0.59, 1.97], <i>p</i> = 0.80) between tirofiban and non-tirofiban group. Besides, the tirofiban administration was associated with lower mortality (OR = 0.75, 95% CI [0.62, 0.91], <i>p</i> = 0.003). <b><i>Conclusions:</i></b> The application of tirofiban in EVT of AIS may improve functional outcomes and reduce mortality at 3 months. Besides, tirofiban does not seem to increase the risk of symptomatic intracranial hemorrhage and intracranial hemorrhage, either in the anterior or posterior circulation stroke.

Symptomatic Intracranial Hemorrhage

Background: Intracranial hemorrhage is a major complication of endovascular treatment in patients with acute ischemic stroke. Controlled clinical trials reported varied incidences of intracranial hemorrhage after endovascular treatment. This meta-analysis aimed to estimate whether endovascular treatment, compared with medical treatment, increases the risk of intracranial hemorrhage in patients with acute ischemic stroke. Methods: The current publications on endovascular treatment for acute ischemic stroke were systematically reviewed. Rates of intracranial hemorrhage after endovascular treatment for acute ischemic stroke reported in controlled clinical trials were pooled and analyzed. Random and fixed-effect models were used to pool the outcomes. For analyzing their individual risks, intracranial hemorrhages after endovascular treatment were classified as symptomatic and asymptomatic. Results: Eleven studies involving 1,499 patients with endovascular treatment and 1,320 patients with medical treatment were included. After pooling the data, the risk of any intracranial hemorrhage was significantly higher in patients with endovascular treatment than in patients with medical treatment (35.0 vs. 19.0%, OR = 2.55, 95% CI: 1.64-3.97, p < 0.00001). The risk of asymptomatic intracranial hemorrhage was also significantly higher in patients with endovascular treatment than in those with medical treatment (28 vs. 12%, OR = 3.16, 95% CI: 1.62-6.16, p < 0.001). However, the risks of symptomatic intracranial hemorrhage were similar in patients with endovascular treatment and in those with medical treatment (5.6 vs. 5.2%, OR = 1.09, 95% CI: 0.79-1.50, p = 0.61). Conclusion: Although the risk of any intracranial hemorrhage may increase after endovascular treatment, the risk of symptomatic intracranial hemorrhage may remain similar as compared with medical treatment.

Background and purposeTo report clinical and procedural outcomes of acute ischemic stroke patients after endovascular treatment with the new thromboaspiration catheter AXS Catalyst 6.MethodsPatients with anterior and posterior circulation stroke were selected. Successful reperfusion defined as a Thrombolysis in Cerebral Infarction (TICI) score ≥2 b and 3-month functional independence defined as a modified Rankin Scale (mRS) ≤2 were the main efficacy outcomes. Symptomatic intracranial hemorrhage and mortality were the main safety outcomes.Results107 patients were suitable for analysis. Mean age was 73.18±12.62 year and median baseline NIHSS was 17 (range: 3–32). The most frequent site of occlusion was the middle cerebral artery (MCA) (60.7%). 76.6% of patients were treated with AXS Catalyst 6 alone without the need for rescue devices or thromboaspiration catheters. Successful reperfusion was achieved in 84.1%, functional independence in 47.6%, symptomatic intracranial hemorrhage occurred in 3.7%, and mortality in 21.4%.ConclusionsEndovascular treatment with AXS Catalyst 6 proved to be safe, technically feasible, and effective. Comparison analyses with other devices for mechanical thrombectomy are needed.

Symptomatic Intracranial Hemorrhage

Background: Symptomatic intracranial hemorrhage (sICH) is a serious hemorrhagic complication after intravenous thrombolysis (IVT) in acute ischemic stroke (AIS) patients. Most existing predictive scoring systems were derived from Western countries Objective: To develop a nomogram to predict the possibility of sICH after IVT in an Asian population. Methods: This retrospective cohort study included AIS patients treated with recombinant tissue plasminogen activator (rt-PA) in a tertiary hospital in Shenzhen, China, from January 2014 to December 2020. The end point was sICH within 36 hours of IVT treatment. Multivariable logistic regression was used to identify risk factors of sICH, and a predictive nomogram was developed. Area under the curve of receiver operating characteristic curves (AUC), calibration curve, and decision curve analyses were performed. The nomogram was validated by bootstrap resampling Results: Data on a total of 462 patients were collected, of whom 20 patients (4.3%) developed sICH. In the multivariate logistic regression model, the National Institute of Health stroke scale scores (NIHSS) (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.06–1.23, P < 0.001), onset to treatment time (OTT) (OR, 1.02; 95% CI, 1.01–1.03, P < 0.001), neutrophil to lymphocyte ratio (NLR) (OR, 1.22; 95% CI, 1.09–1.35, P < 0.001), and cardioembolism (OR, 3.74; 95% CI, 1.23–11.39, P = 0.020) were independent predictors for sICH and were used to construct a nomogram. Our nomogram exhibited favorable discrimination ability [AUC, 0.878; specificity, 87.35%; and sensitivity, 73.81%]. Bootstrapping for 500 repetitions was performed to further validate the nomogram. The AUC of the bootstrap model was 0.877 (95% CI: 0.823–0.922). The calibration curve exhibited good fit and calibration. The decision curve revealed good positive net benefits and clinical effects Conclusion: The nomogram consisted of the predictors NIHSS, OTT, NLR, and cardioembolism could be used as an auxiliary tool to predict the individual risk of sICH in Chinese AIS patients after IVT. Further external verification among more diverse patient populations is needed to demonstrate the accuracy of the model’s predictions.

Background: Recent trials have demonstrated a reduction in death or disability with endovascular treatment in patients with acute ischemic strokes. However, readmission rates and predictors are not known. Objective: To identify rates and factors associated with 30-day readmission after endovascular treatment in ischemic stroke patients. Methods: Nationwide Readmissions Data (NRD) between 2010 and 2017 was utilized to identify endovascular treatment in acute ischemic stroke patients using ICD-9 and ICD-10 codes. We used hierarchical logistic regression model to identify factors associated with 30-day readmissions. Results: Among 17, 562 acute ischemic stroke patients who survived to discharge after endovascular treatment, 2334 (13.29%) were readmitted within 30-days. Age => 65 years (odds ratio [OR]: 1.23, 95% confidence interval [CI]: 1.09 to 1.39, p =0.0005), chronic kidney disease (OR: 1.28, 95%CI: 1.12 to 1.47, p = 0.0004), congestive heart failure (OR: 1.25, 95%CI: 1.13 to 1.39, p <.0001), post procedure intracranial hemorrhage (OR: 1.09, 95%CI: 0.99 to 1.20, p = 0.04) and diabetes mellitus (OR: 1.09, 95%CI: 0.99 to 1.20, p = .09) during the index hospitalization were associated with readmission within 30 days. Conclusion: In this large nationally representative study, nearly one in 10 patients were readmitted within 30 days after discharge in acute ischemic stroke patients undergoing endovascular treatment. Medical comorbidities and post procedure intracranial hemorrhage were associated with 30-day readmission.
