BackgroundWe aimed to compare the outcome of acute ischemic stroke (AIS) patients who received endovascular thrombectomy (EVT) with confirmed COVID-19 to those without.MethodsWe performed a retrospective analysis using the Vizient Clinical Data Base and included hospital discharges from April 1 to July 31 2020 with ICD-10 codes for AIS and EVT. The primary outcome was in-hospital death and the secondary outcome was favorable discharge, defined as discharge home or to acute rehabilitation. We compared patients with laboratory-confirmed COVID-19 to those without. As a sensitivity analysis, we compared COVID-19 AIS patients who did not undergo EVT to those who did, to balance potential adverse events inherent to COVID-19 infection.ResultsWe identified 3165 AIS patients who received EVT during April to July 2020, in which COVID-19 was confirmed in 104 (3.3%). Comorbid COVID-19 infection was associated with younger age, male sex, diabetes, black race, Hispanic ethnicity, intubation, acute coronary syndrome, acute renal failure, and longer hospital and intensive care unit length of stay. The rate of in-hospital death was 12.4% without COVID-19 vs 29.8% with COVID-19 (P<0.001). In mixed-effects logistic regression that accounted for patient clustering by hospital, comorbid COVID-19 increased the odds of in-hospital death over four-fold (OR 4.48, 95% CI 3.02 to 6.165). Comorbid COVID-19 was also associated with lower odds of a favorable discharge (OR 0.43, 95% CI 0.30 to 0.61). In the sensitivity analysis, comparing AIS patients with COVID-19 who did not undergo EVT (n=2139) to the AIS EVT patients with COVID-19, there was no difference in the rate of in-hospital death (30.6% vs 29.8%, P=0.868), and AIS EVT patients had a higher rate of favorable discharge (32.4% vs 47.1%, P=0.002).ConclusionIn AIS patients treated with EVT, comorbid COVID-19 infection was associated with in-hospital death and a lower odds of favorable discharge compared with patients without COVID-19, but not compared with AIS patients with COVID-19 who did not undergo EVT. AIS EVT patients with COVID-19 were younger, more likely to be male, have systemic complications, and almost twice as likely to be black and over three times as likely to be Hispanic.

Background and Purpose: This study aimed to evaluate the treatment effect of intraarterial versus intravenous tirofiban during endovascular thrombectomy in acute ischemic stroke. Methods: This study retrospectively examined 503 patients with acute ischemic stroke with large vessel occlusion who received endovascular thrombectomy within 24 hours of stroke onset. Patients were divided into 3 groups: no tirofiban (n=354), intraarterial tirofiban (n=79), and intravenous tirofiban (n=70). The 3 groups were compared in terms of recanalization rate, symptomatic intracerebral hemorrhage, in-hospital death rate, 3-month death, and 3-month outcomes measured by modified Rankin Scale score (good clinical outcome of 0–2, poor outcome of 5–6). The comparison was statistically assessed by propensity score matching, followed by Freidman rank-sum test and pairwise Wilcoxon signed-rank test with Bonferroni correction. Results: The propensity score matching resulted in 92 matched triplets. Compared with the no-tirofiban group, the intravenous tirofiban group showed significantly increased recanalization (96.7% versus 64.1%, P <0.001), an increased rate of 3-month good outcome (69.5% versus 51.2%, P =0.034), and a lower rate of 3-month poor outcome (12.2% versus 41.4%, P <0.001). There was no significant difference between the tirofiban intravenous and no-tirofiban groups in terms of symptomatic intracerebral hemorrhage (2.2% versus 0%, P =1.000). However, symptomatic intracerebral hemorrhage was significantly increased in the intraarterial-tirofiban group compared with the no-tirofiban group (19.1% versus 0%, P <0.001), with an increased rate of in-hospital death (23.6% versus 0% P <0.001), and increased rate of 3-month death (26.8% versus 11.1%, P =0.021). The intraarterial-tirofiban and no-tirofiban group showed no significant difference in recanalization rate (66.3% versus 64.1%, P =1.000). Conclusions: As an adjunct to endovascular thrombectomy, intravenous tirofiban is associated with high recanalization rate and good outcome, whereas intraarterial tirofiban is associated with high hemorrhagic rate and death rate.

Background: The efficacy of endovascular thrombectomy (EVT) for large vessel occlusion in elderly is controversial as this age group is often excluded or under-represented in major randomized clinical trials. We evaluated the real-world trends in utilization and outcome of EVT in patients ≥80 years in a nationally representative database. Methods: Using nationwide inpatient sample (2014-2016), we identified patients admitted to hospitals in the United States with acute ischemic stroke who underwent EVT. Baseline demographics and clinical outcome were assessed among patients with age ≥80 years and those with age <80 years. The primary endpoint was favorable outcome defined as discharge to home or acute rehabilitation center. Hemorrhage and in-hospital mortality rates were assessed as secondary outcome measures. Multivariate analysis was performed to identify independent predictors of favorable clinical outcome in elderly. Results: A total of 6,230 patients were identified and 1,547 (24.83%) of them were ≥80. The number of patients ≥80 years who underwent EVT increased from 323 (22%) in 2014 to 695 (28%) in 2016. The rate of favorable outcome in elderly was 9% which was significantly lower than in younger patients (22%). In-hospital mortality was 19% in patients ≥80 years compared to 13% in their younger counterpart. There was no difference in the rate of hemorrhagic transformation between octogenarians and younger patients (3.2% vs 2.6%). Among patient ≥80, decreasing baseline comorbidity burden (Elixhauser Comorbidity Index) [OR; (95% CI): 1.24; (1.04-1.47)] was an independent predictor of favorable outcome. Conclusions: Two-fold increase in the number of EVT was seen from 2014 to 2016 among patients ≥80 years old. Although the rate of favorable outcome is lower in this age group, comparison to a historical control group suggests significant outcome benefit from EVT in these patients. Future prospectively designed studies are warranted for further characterization of the risks and benefit of EVT in elderly.

Abstract Whether and how SARS-CoV-2 outbreak affected in-hospital acute stroke care system is still matter of debate. In the setting of the STROKOVID network, a collaborative project between the 10 centers designed as hubs for the treatment of acute stroke during SARS-CoV-2 outbreak in Lombardy, Italy, we retrospectively compared clinical features and process measures of patients with confirmed infection (COVID-19) and non-infected patients (non-COVID-19) who underwent reperfusion therapies for acute ischemic stroke. Between March 8 and April 30, 2020, 296 consecutive patients (median age, 74 [interquartile range (IQR), 62–80.75] years; males, 154 [52.0%]; 34 [11.5%] COVID-19) qualified for the analysis. Time from symptoms onset to treatment was longer in the COVID-19 group (230 [IQR, 200.5–270] minutes vs 190 [IQR, 150–245] minutes; p=0.007), especially in the first half of the study period. Patients with COVID-19 who underwent endovascular thrombectomy had more frequently absent collaterals or collaterals filling ≤50% of the occluded territory (50.0% vs 16.6%; OR, 5.05; 95% CI, 1.82–13.80) and a lower rate of good/complete recanalization of the primary arterial occlusive lesion (55.6% vs 81.0%; OR, 0.29; 95% CI, 0.10–0.80). Post-procedural intracranial hemorrhages were more frequent (35.3% vs 19.5%; OR, 2.24; 95% CI, 1.04-4.83) and outcome was worse among COVID-19 patients (in-hospital death, 38.2% vs 8.8%; OR, 6.43; 95% CI, 2.85-14.50). Our findings showed longer delays in the intra-hospital management of acute ischemic stroke in COVID-19 patients, especially in the early phase of the outbreak, that likely impacted patients outcome and should be the target of future interventions.

<b><i>Introduction:</i></b> The management and prognosis of acute ischemic stroke due to multiple large-vessel occlusion (LVO) (MLVO) are not well scrutinized. We therefore aimed to elucidate the differences in patient characteristics and prognosis of MLVO and single LVO (SLVO). <b><i>Methods:</i></b> The Recovery by Endovascular Salvage for Cerebral Ultra-Acute Embolism Japan Registry 2 (RESCUE-Japan Registry 2) enrolled 2,420 consecutive patients with acute LVO who were admitted within 24 h of onset. We compared patient prognosis between MLVO and SLVO in the favorable outcome, defined as a modified Rankin Scale (mRS) score ≤2, and in mortality at 90 days by adjusting for confounders. Additionally, we stratified MLVO patients into tandem occlusion and different territories, according to the occlusion site information and also examined their characteristics. <b><i>Results:</i></b> Among the 2,399 patients registered, 124 (5.2%) had MLVO. Although there was no difference between the 2 groups in terms of hypertension as a risk factor, the mean arterial pressure on admission was significantly higher in MLVO (115 vs. 107 mm Hg, <i>p</i> = 0.004). MLVO in different territories was more likely to be cardioembolic (42.1 vs. 10.4%, <i>p</i> = 0.0002), while MLVO in tandem occlusion was more likely to be atherothrombotic (39.5 vs. 81.3%, <i>p</i> &#x3c; 0.0001). Among MLVO, tandem occlusion had a significantly longer onset-to-door time than different territories (200 vs. 95 min, <i>p</i> = 0.02); accordingly, the tissue plasminogen activator administration was significantly less in tandem occlusion (22.4 vs. 47.9%, <i>p</i> = 0.003). However, interestingly, the endovascular thrombectomy (EVT) was performed significantly more in tandem occlusion (63.2 vs. 41.7%; adjusted odds ratio [aOR], 2.3; 95% confidence interval [CI], 1.1–5.0). The type of MLVO was the only and significant factor associated with EVT performance in multivariate analysis. The favorable outcomes were obtained less in MLVO than in SLVO (28.2 vs. 37.1%; aOR, 0.48; 95% CI, 0.30–0.76). The mortality rate was not significantly different between MLVO and SLVO (8.9 vs. 11.1%, <i>p</i> = 0.42). <b><i>Discussion/Conclusion:</i></b> The prognosis of MLVO was significantly worse than that of SLVO. In different territories, we might be able to consider more aggressive EVT interventions.

Introduction: The prognosis of patients suffering acute ischemic stroke (AIS) is worsened by medical complications that occur during subsequent hospitalization. The incidence, risk factors, and outcomes of gastrointestinal bowel obstruction (GIBO) in AIS have not been previously reported. Methods: We employed the Nationwide Inpatient Sample from 2002 to 2011 to identify all patients admitted with a primary diagnosis of AIS and subsets with and without a secondary diagnosis of GIBO without hernia. Multivariate logistic regression was utilized to analyze predictors of GIBO in AIS patients and the association between GIBO, in-hospital complications, and outcomes. Results: We identified 16,987 patients with GIBO (425 per 100,000) among 3,988,667 AIS hospitalizations and 4.2% of patients of these patients underwent repair surgery for intestinal obstruction. Multivariate predictors of GIBO included: age 55-64 (OR: 1.52, 95% CI: 1.40-1.64), age 65-74 (OR: 1.69, 95% CI: 1.56-1.84), age 75+ (OR: 1.97, 95% CI: 1.81-2.13), black race (OR: 1.42, 95% CI: 1.36-1.49), coagulopathy (OR: 1.39, 95% CI: 1.29-1.50), cancer (OR: 1.59, 95% CI: 1.44-1.75), blood loss anemia (OR: 2.51, 95% CI: 2.22-2.84), fluid/electrolyte disorder (OR: 2.91, 95% CI: 2.81-3.02), weight loss (OR: 3.08, 95% CI: 2.93-3.25), and thrombolytic therapy (OR: 1.30, 95% CI: 1.20-1.42) (all p<0.0001). Patients with GIBO had a greater likelihood of suffering intubation (OR: 1.79, 95% CI: 1.70-1.90), deep vein thrombosis (OR: 1.35, 95% CI: 1.25-1.46), pulmonary embolism (OR: 1.84, 95% CI: 1.53-2.21), sepsis (OR: 2.39, 95% CI: 2.22-2.56), acute kidney injury (OR: 1.85, 95% CI: 1.76-1.95), gastrointestinal hemorrhage (OR: 2.82, 95% CI: 2.63-3.03), and blood transfusions (OR: 2.02, 95% CI: 1.90-2.15) (all p<0.0001). In adjusted analyses, AIS patients with GIBO were 284% and 39% more likely to face moderate to severe disability and in-hospital death, respectively (p<0.0001). GIBO occurrence increased length of stay and total costs by an average of 9.7 days and $22,342 (p<0.0001). Conclusion: Advanced age, black race, and several pre-existing comorbidities increase the likelihood of post-AIS GIBO, which is an independent predictor of in-hospital complications, disability, and mortality.

Selection Of

AbstractAppropriate patient selection and expedient recanalization are the mainstay of modern management of acute ischemic stroke (AIS). Only a minority of patients (7–15%) of patients are eligible for endovascular therapy. Patient selection may be time based or perfusion based. Central to both paradigms is the selection of a patient with a small core, a significant penumbra that can be differentiated from areas of oligemia. A brief review of patient selection methods is presented. Endovascular thrombectomy techniques using stentrievers or aspiration catheters have now become the treatment of choice for AIS with large vessel occlusion. A range of devices, each with its own advantages and disadvantages, are available in the market for the neurointerventionist to choose. Techniques vary between devices and between operators, but standardization and protocolization are important within each center. Complications must be anticipated to be avoided. Once reperfusion is achieved, outcomes must be safeguarded with competent postprocedure management to prevent secondary brain injury. These aspects are reviewed in this article.
