First Pass

BackgroundFirst pass effect (FPE), defined as near-total/total reperfusion of the territory (modified Thrombolysis in Cerebral Infarction (mTICI) 2c/3) of the occluded artery after a single thrombectomy attempt (single pass), has been associated with superior safety and efficacy outcomes than in patients not experiencing FPE.ObjectiveTo characterize the clinical features, incidence, and predictors of FPE in the anterior and posterior circulation among patients enrolled in the Trevo Registry.MethodsData were analyzed from the Trevo Retriever Registry. Univariate and multivariable analyses were used to assess the relationship of patient (demographics, clinical, occlusion location, collateral grade, Alberta Stroke Program Early CT Score (ASPECTS)) and device/technique characteristics with FPE (mTICI 2c/3 after single pass).ResultsFPE was achieved in 27.8% (378/1358) of patients undergoing anterior large vessel occlusion (LVO) thrombectomy. Multivariable regression analysis identified American Society of Interventional and Therapeutic Neuroradiology (ASITN) levels 2–4, higher ASPECTS, and presence of atrial fibrillation as independent predictors of FPE in anterior LVO thrombectomy. Rates of modified Rankin Scale (mRS) score 0–2 at 90 days were higher (63.9% vs 53.5%, p<0.0006), and 90-day mortality (11.4% vs 12.8%, p=0.49) was comparable in the FPE group and non-FPE group. Rate of FPE was 23.8% (19/80) among basilar artery occlusion strokes, and outcomes were similar between FPE and non-FPE groups (mRS score 0–2, 47.4% vs 52.5%, p=0.70; mortality 26.3% vs 18.0%, p=0.43). Notably, there were no difference in outcomes in FPE versus non-FPE mTICI 2c/3 patients.ConclusionTwenty-eight percent of patients undergoing anterior LVO thrombectomy and 24% of patients undergoing basilar artery occlusion thrombectomy experience FPE. Independent predictors of FPE in anterior circulation LVO thrombectomy include higher ASITN levels, higher ASPECTS, and the presence of atrial fibrillation.

Background: Liver fibrosis has been identified as an outcome predictor in cardiovascular disease and has been associated with hematoma expansion and mortality in patients with primary intracerebral hemorrhage. We aimed to explore whether clinically inapparent liver fibrosis is related to neurological outcome, mortality, and intracranial hemorrhage risk in ischemic stroke patients after mechanical thrombectomy. Methods: We included consecutive patients with anterior circulation large vessel occlusion stroke treated at our center with mechanical thrombectomy between January 2011 and April 2019. Clinical data had been collected prospectively; laboratory data were extracted from our electronic hospital information system. We calculated the Fibrosis-4 index (FIB-4), an established non-invasive liver fibrosis test. The main outcomes were postinterventional intracranial hemorrhage, unfavorable functional status (modified Rankin scale scores of 3–6), and mortality three months post-stroke. Results: In the 460 patients (mean age 69 years, 49.3% female) analyzed, FIB-4 indicated advanced liver fibrosis in 22.6%. Positive FIB-4 was associated with unfavorable neurological outcomes and mortality three months post-stroke, even after correction for co-factors [Odds Ratio (OR) 2.15 for unfavorable outcome in patients with positive FIB-4, 95% confidence interval (CI) 1.21–3.83, p = 0.009, and 2.16 for mortality, 95% CI 1.16–4.03, p = 0.01]. However, FIB-4 was neither related to hemorrhagic transformation nor symptomatic intracranial hemorrhage. Moreover, atrial fibrillation was more frequent in patients with liver fibrosis ( p < 0.001). Two further commonly-used liver fibrosis indices (Forns index and the Easy Liver Fibrosis Test) yielded comparable results regarding outcome and atrial fibrillation. Conclusions: Clinically inapparent liver fibrosis (based on simple clinical and laboratory parameters) represents an independent risk factor for unfavorable outcomes, including mortality, at three months after stroke thrombectomy. Elevated liver fibrosis indices warrant further hepatological work-up and thorough screening for atrial fibrillation in stroke patients.

Background Atrial fibrillation is an important risk factor for ischemic stroke, and is associated with an increased risk of poor outcome after ischemic stroke. Endovascular thrombectomy is safe and effective in acute ischemic stroke patients with large vessel occlusion of the anterior circulation. This meta-analysis aims to investigate whether there is an interaction between atrial fibrillation and treatment effect of endovascular thrombectomy, and secondarily whether atrial fibrillation is associated with worse outcome in patients with ischemic stroke due to large vessel occlusion. Methods Individual patient data were from six of the recent randomised clinical trials (MR CLEAN, EXTEND-IA, REVASCAT, SWIFT PRIME, ESCAPE, PISTE) in which endovascular thrombectomy plus standard care was compared to standard care alone. Primary outcome measure was the shift on the modified Rankin scale (mRS) at 90 days. Secondary outcomes were functional independence (mRS 0–2) at 90 days, National Institutes of Health Stroke Scale score at 24 h, symptomatic intracranial hemorrhage and mortality at 90 days. The primary effect parameter was the adjusted common odds ratio, estimated with ordinal logistic regression (shift analysis); treatment effect modification of atrial fibrillation was assessed with a multiplicative interaction term. Results Among 1351 patients, 447 patients had atrial fibrillation, 224 of whom were treated with endovascular thrombectomy. We found no interaction of atrial fibrillation with treatment effect of endovascular thrombectomy for both primary ( p-value for interaction: 0.58) and secondary outcomes. Regardless of treatment allocation, we found no difference in primary outcome (mRS at 90 days: aOR 1.11 (95% CI 0.89–1.38) and secondary outcomes between patients with and without atrial fibrillation. Conclusion We found no interaction of atrial fibrillation on treatment effect of endovascular thrombectomy, and no difference in outcome between large vessel occlusion stroke patients with and without atrial fibrillation.

Objective: The preventability of strokes treated by mechanical thrombectomy is unknown. The purpose of this study was to analyze stroke preventability for patients treated with mechanical thrombectomy for large vessel occlusion.Methods: We conducted retrospective analyses of 300 patients (mean ± SE age 69 ± 0.9 years, range 18–97 years; 53% male) treated with mechanical thrombectomy for large vessel occlusion from January 2008 to March 2019. We collected data including demographics, NIH Stroke Scale (NIHSS) at onset, and (beginning in 2015) classified 90-day outcome by modified Rankin Scale (mRS). Patients were evaluated using a Stroke Preventability Score (SPS, 0 to 10 points) based on how well patients had been treated given their hypertension, hyperlipidemia, atrial fibrillation, and prior stroke history. We examined the relationship of SPS with NIHSS at stroke onset and with mRS outcome at 90 days.Results: SPS was calculated for 272 of the 300 patients, with mean ± SE of 2.1 ± 0.1 (range 0–8); 89 (33%) had no preventability (score 0), 120 (44%) had low preventability (score 1–3), and 63 (23%) had high preventability (score 4 or higher). SPS was significantly correlated with age (r = 0.32, p &lt; 0.0001), while NIHSS (n = 267) was significantly higher (p = 0.03) for patients with high stroke preventability vs. low/no preventability [18.8 ± 0.92 (n = 62) vs. 16.5 ± 0.51 (n = 205)]. Among 118 patients with mRS, outcome was significantly worse (p = 0.04) in patients with high stroke preventability vs. low/no preventability [4.7 ± 0.29 (n = 28) vs. 3.8 ± 0.21 (n = 90)]. The vast majority of patients with high stroke preventability had inadequately treated atrial fibrillation (85%, 53/62).Conclusions: Nearly one quarter of stroke patients undergoing mechanical thrombectomy had highly preventable strokes. While stroke preventability showed some relationship to stroke severity at onset and outcome after treatment, preventability had the strongest association with age. These findings emphasize the need for improved stroke prevention in the elderly.

Background and purpose Successful reperfusion can be achieved in more than two-thirds of patients with usual large-vessel occlusion stroke causes treated with mechanical thrombectomy. However, the safety and outcomes after mechanical thrombectomy in the setting of large-vessel occlusion related to infective endocarditis is not known. In this study, we investigated the impact of mechanical thrombectomy in infective endocarditis patients on angiographic and clinical outcomes. Methods This was a multicenter study from five comprehensive stroke centers. We compared the outcomes of mechanical thrombectomy treated stroke patients due to infective endocarditis with patients presenting atrial fibrillation. Clinical outcomes included 90-day modified Rankin Scale, symptomatic intracerebral hemorrhage, and mortality. Results Between June 2013 and March 2019, 28 patients presenting large-vessel occlusion stroke due to IE were included. These cases were matched with 84 large-vessel occlusion stroke related to atrial fibrillation. Successful reperfusion (modified Thrombolysis in Cerebral Infarction 2b/3) was obtained in 85.7%. Symptomatic intracranial hemorrhage, favorable outcome and mortality rates were respectively 8.0%, 25.9%, and 25.9%. In the case–control analysis, we demonstrated no difference in terms of successful reperfusion, procedural complication, symptomatic intracranial hemorrhage, and mortality rates. Three-month favorable outcome was less often achieved in the infective endocarditis group. Conclusions Mechanical thrombectomy of infective endocarditis patients presents similar safety and angiographic results compared to patients suffering from atrial fibrillation.

Background Patients with large vessel occlusion stroke (LVOS) need to be rapidly identified and transferred to comprehensive stroke centers. However, current prehospital evaluation and strategies still remain challenging. Methods and Results We retrospectively reviewed our prospectively collected database of patients with acute ischemic stroke (AIS). Based on the items of National Institutes of Health Stroke Scale and medical history that had a strong association with LVOS, we designed the 4‐item Stroke Scale (4I‐SS) and validated it in multi‐centers. The 4I‐SS incorporated gaze, level of consciousness, arm weakness, and atrial fibrillation. Receiver operating characteristic analysis was used to compare the 4I‐SS with previously established prehospital prediction scales. Finally, 1630 and 11 440 patients were included in the derivation and validation cohort, respectively. In the validation cohort, Youden Index, area under the curve, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the 4I‐SS≥4 to predict LVOS were 0.494, 0.800, 0.657, 0.837, 0.600, 0.868, and 0.788, respectively, and that of the 4I‐SS≥7 to predict basilar artery occlusion were 0.200, 0.669, 0.229, 0.971, 0.066, 0.974, and 0.899, respectively. Youden Index and area under the curve were higher than previously published scales for predicting LVOS. Further analysis showed that for predicting whether cardiogenic embolism was the cause, its accuracy was 0.922 when the 4I‐SS score, including atrial fibrillation, was ≥6, and its accuracy of predicting the occluded vessel was intracranial internal carotid artery or M1 segment of the middle cerebral artery when it was ≥7 was 0.590. Conclusions The 4I‐SS is an effective and simple tool that can identify LVOS and its cause. Registration URL: https://www.clinicaltrials.gov ; Unique identifier: NCT03317639.
