Introduction: Limited data exist about the safety and efficacy of repeat mechanical thrombectomy (MT) in patients with recurrent large vessel occlusion (rLVO). Here, we present a case series examining the outcome of early and delayed rLVO and the safety of repeat MT. Methods: We reviewed our prospectively-collected endovascular database for acute ischemic stroke (AIS) patients with LVO who underwent MT between July 2012 and February 2020. We included patients with recurrent stroke requiring repeat MT after successful first MT, either in the same vessel or in a different vascular territory, within 24 hours up to 924 days and compared it with patients who underwent single MT. Baseline demographics, angiographic, procedural, and outcomes data were compared in AIS patients who underwent recurrent MT (RT) versus single MT (ST). We completed a meta-analysis that evaluated papers from 2015 to 2020 which examined reocclusion after MT. Result: A total of 738 MT patients were included, of which 726 (98.4%) were in the ST group and 12 (1.6%) in the RT group (Table 1). Baseline characteristics were well balanced between the cohorts. The most common site of occlusion was in the MCA territory. Last known well (559 ± 982 vs. 267 ± 301 minutes, p = 0.358) was similar between the groups. There was no difference in the median number of passes (2 IQR 1-3, p=0.61) in the ST and RT groups, respectively. In the RT group, the mean time between repeat occlusion was 132.5 ± 275 days. Revascularization success, sICH rates (25% vs. 7.1%, p= 0.306), and mean 90-day mRS (1.3 ± 2.3 vs. 1.8 ± 2.7, p = 0.63) did not differ between the first MT (FT) and RT cohorts. No association between reocclusion and MT device (aspiration or stent-retriever), tPA given, statin, antiplatelet or anticoagulation therapy was found in the meta-analysis. Conclusion: Repeat MT in patients with early or delayed reocclusion appears to be safe. Larger, prospective studies are needed to evaluate these findings.

Few Data

BackgroundFew data are available regarding the safety and efficacy of antiplatelet (APT) pretreatment in acute ischemic stroke (AIS) patients with emergent large vessel occlusions (ELVO) treated with mechanical thrombectomy (MT). We sought to evaluate the association of APT pretreatment with safety and efficacy outcomes following MT for ELVO.MethodsConsecutive ELVO patients treated with MT during a 4-year period in a tertiary stroke center were evaluated. The following outcomes were documented using standard definitions: symptomatic intracranial hemorrhage (sICH), successful recanalization (SR; modified TICI score 2b/3), mortality, and functional independence (modified Rankin Scale scores of 0–2).ResultsThe study population included 217 patients with ELVO (mean age 62±14 years, 50% men, median NIH Stroke Scale score 16). APT pretreatment was documented in 71 cases (33%). Patients with APT pretreatment had higher SR rates (77% vs 61%; P=0.013). The two groups did not differ in terms of sICH (6% vs 7%), 3-month mortality (25% vs 26%), and 3-month functional independence (50% vs 48%). Pretreatment with APT was independently associated with increased likelihood of SR (OR 2.18, 95% CI1.01 to 4.73; P=0.048) on multivariable logistic regression models adjusting for potential confounders. A significant interaction (P=0.014) of intravenous thrombolysis (IVT) pretreatment on the association of pre-hospital antiplatelet use with SR was detected. APT pretreatment was associated with SR (OR 2.74, 95% CI 1.15 to 6.54; P=0.024) in patients treated with combination therapy (IVT and MT) but not in those treated with direct MT (OR 1.78, 95% CI 0.63 to 5.03; P=0.276).ConclusionAPT pretreatment does not increase the risk of sICH and may independently improve the odds of SR in patients with ELVO treated with MT. The former association appears to be modified by IVT.

Introduction : Mechanical thrombectomy (MT) has become the current standard of care for large vessel occlusion stroke but is associated with an increased risk of intracranial hemorrhage (ICH). Although several studies have investigated the risk factors, there is still limited, not well‐established data. This study aims to evaluate the risk factors of HT after MT. Methods : We retrospectively reviewed all MT patients who were treated at a single comprehensive stroke center from 12/2016 to 7/2019. Variables included initial NIHSS, blood glucose, initial systolic blood pressure, age, gender, IV tPA, time from door to recanalization, and TICI score. Outcome measures were HT on post‐procedure or 24‐hour post‐tPA head CT/MRI as well as modified Rankin scale (mRS) upon discharge. Results : Among 74 patients (68.8 ± 14 years, men 47.3%), 9 (12.2%) experienced hemorrhagic transformation after thrombectomy. Average admitting NIHSS was significantly higher in the HT group (22 vs 16.8, p = 0.041). TICI 3 after MT was protective for HT (OR 0.078, 95% CI 0.009‐0.663). IV tPA (OR 3.86, 95% CI 1.448‐10.326) was associated with good neurological outcome at discharge (mRS < = 2), but HT was not (OR 0.114, 95% CI 0.013‐0.964). Patients with mRS < = 2 upon discharge were younger (65.2±12 vs 71.9±15, p = 0.04) and had lower initial BG (124±45.8 vs 157±69.6, P = 0.02). Conclusions : TICI 3 score, decreased NIHSS, and lower BG were associated with less HT and better outcomes in our MT cohort. Admitting NIHSS > = 20 may be a reasonable threshold to predict HT after MT. Our findings are consistent with the TICI‐ASPECTS‐glucose (TAG) score to predict sICH; however, we used initial NIHSS as a surrogate for ASPECTS. Further studies may utilize additional quantitative measures such as CTP data to predict HT.

The Impact

Background and objective: Elderly patients were underrepresented in RCTs that proved the efficacy and safety of mechanical thrombectomy (MT) in acute ischemic strokes (AIS) due to large vessel occlusion (LVO). Additionally, the impact of race and socio-economics in AIS outcomes is well-reported. We sought to assess MT clinical outcomes in Hispanic Octogenarians and Nonagenarians that reside in underserved border communities. Methods: A retrospective cohort study from a prospectively collected comprehensive stroke center database was conducted. The primary outcome was discharge (mRS 0-2). Secondary outcomes were NIHSS improvement ≥4 points at discharge, sICH, mortality and length of stay (LOS). A two-tailed t-test assessed statistical significance between the two groups. Results: Of 202 included patients, 172 (85%) were octogenarians and 30 nonagenarians (17%). Nonagenarians had higher rates of females (80% vs 59%; p<0.05), similar rates of Hispanics (57% vs. 63%, p-xx) and a trend towards higher NIHS (20 vs. 17, P=0.09). Other baseline characteristics were similar (Table 1). Time last known well to arrival to MT center and to recanalization were longer in octogenarians, all other time metrics did not differ. Nonagenarians had numerically lower favorable outcomes at discharge (7% vs. 16%, p=0.11) as compared to octogenarians. Rates of clinical improvement on NIHSS were similar (27% vs. 23%, p=0.74). Mortality (23% vs. 28%, p=0.63) and sICH (7% vs 4%, p=0.46), octogenarians and nonagenarians, respectively. Octogenarians trended towards longer LOS (10 vs 6 days, p=0.05). Conclusions: Both groups had lower favorable good outcome rates than MT outcomes reported in RCTs. Nonagenarians had numerically lower favorable outcomes but mortality and sICH were similar. Further studies are warranted to further assess the impact of age and socioeconomics on MT outcomes.

The Impact

IntroductionWe sought to evaluate the impact of pretreatment with intravenous thrombolysis (IVT) on the rate and speed of successful reperfusion (SR) in patients with emergent large vessel occlusion (ELVO) treated with mechanical thrombectomy (MT) in a high-volume tertiary care stroke center.MethodsConsecutive patients with ELVO treated with MT were evaluated. Outcomes were compared between patients who underwent combined IVT and MT (IVT+MT) and those treated with direct MT (dMT). The elapsed time between groin puncture to beginning of reperfusion (GPTBRT) and the numbers of device passes required to achieve SR were also documented.ResultsA total of 287 and 132 patients were treated with IVT+MT and dMT, respectively. The IVT+MT group had higher SR (73.8% vs 62.9%; p=0.023) and 3-month functional independence (modified Rankin Scale score 0–2;51.6% vs 38.2%; p=0.008) rates. The median GPTBRT was shorter in the IVT+MT group (48 (IQR 33–70) vs 70 (IQR 44–98) min; p<0.001). Among patients who achieved SR (n=292), the median number of required device passes was lower in the IVT+MT subgroup (1 (IQR 1–1) vs 2 (IQR 1–2); p<0.001), while the rate of patients requiring ≤2 device passes was higher (98% vs 77%; p<0.001). IVT+MT was independently related to higher odds of SR (OR 1.64; 95% CI 1.03 to 2.61; p=0.036) and shorter GPTBRT (unstandardized linear regression coefficient −20.39; 95% CI −27.56 to –13.22; p<0.001) on multivariable analyses adjusting for potential confounders. Among patients with SR, IVT+MT was independently associated with a higher likelihood of ≤2 device passes (OR 14.63; 95% CI 4.46 to 48.00; p<0.001).ConclusionsIVT pretreatment appears to increase the rates of SR and shortens the duration of the endovascular procedure by requiring fewer device passes in patients with ELVO treated with MT.

Introduction and hypothesis: In patients with acute ischemic stroke with large vessel occlusion (AIS-LVO), the role of intra-arterial adjunctive medications (IAM) like urokinase, tPA or glycoprotein IIb/IIIa inhibitors, during mechanical thrombectomy (MT) has not been clearly established. We hypothesize that AIS-LVO patients treated with both MT + IAM (rescue or concurrent) achieve better safety and efficacy outcomes than patients treated with MT alone and aim to determine the efficacy and safety of concomitant or rescue IAM for AIS-LVO patients undergoing MT. Methods: We searched Medline, Embase and Cochrane Stroke Group Trials Register databases from inception until 13th March 2020. We analysed all studies with patients diagnosed with AIS-LVO in the anterior or posterior circulation, that provided data for the two treatment arms: 1)MT+IAM and 2)MT-only, and also reported on at least one of the following outcomes: reperfusion, 90-days modified Rankin Scale (mRS), symptomatic intracranial hemorrhage (sICH) and 90-days mortality. Data were collated in accordance with the PRISMA guidelines. Results: Sixteen non-randomized observational studies with a total of 4581 patients were analysed. MT-only was performed in 3233 (70.6%) patients, while 1348 (29.4%) patients were treated with both MT+IAM. As compared to patients treated with MT alone, patients treated with combination therapy (MT +IAM) had a higher likelihood of achieving good functional outcome (risk ratio=1.13, 95% CI 1.03-1.24) and a lower risk of 90-day mortality (risk ratio=0.82, 95% CI 0.72-0.94). There was no significant difference in successful reperfusion (risk ratio=1.02, 95% CI 0.99-1.06) and sICH between the two groups (risk ratio = 1.13, 95% CI 0.87-1.46) (Figure 1). Conclusions: In AIS-LVO, use of IAM together with MT may achieve better functional outcomes and lower mortality rates. Randomized controlled trials are warranted to confirm the safety and efficacy of IAM as adjunctive treatment of MT.

Repeat Imaging

Introduction : Background: A common convention among stroke patients being transferred for mechanical thrombectomy, particularly if intravenous thrombolysis has been given, is to undergo a repeat plain brain CT at the treating stroke center. The most concerning among several concerns is the discovery of intracerebral hemorrhage (ICH) which would obviate the value of thrombectomy. This practice has been shown in a previous series to result in a median treatment delay of 20 minutes[1]. By determining the actual incidence of any ICH seen on neuroimaging in patients who undergo repeat imaging on arrival to comprehensive stroke center prior to intervention, we can better determine the true value of this convention of repeat imaging. Methods : Retrospective review of all patients transferred to a single academic comprehensive stroke center for mechanical thrombectomy. We evaluated for the frequency of repeat imaging, the rate of ICH and the rate of undergoing mechanical thrombectomy. Results : There were 682 patients transferred directly for mechanical thrombectomy evaluation over the study period. Intravenous Alteplase was administered to 391 patients prior to arrival and 2 had it on arrival to destination hospital. Plain head CT was repeated at the hub hospital in 590/682 patients (86.5%) (348 with thrombolytics and 242 without. A new intracerebral hemorrhage (ICH) was detected in 9 patients. In only 3 of the 9 patients was mechanical thrombectomy deferred solely due to the ICH (other 6 had no evidence of LVO (4), low ASPECTS (1) or exam improvement (1)). Conclusions : In patients being transferred for mechanical thrombectomy, the rate of ICH on arrival to site hospital was 1.5%. In only one third of those patients (0.5%) was the decision to not proceed with mechanical thrombectomy related to the new ICH. Given the delays in door to puncture times associated with repeat imaging indicated in literature and the low yield in detecting ICH in transfer patients, repeating neuroimaging at comprehensive stroke center obtained for the purpose of ruling out ICH on patients transferred for MT should be reconsidered. Limitations: Our study reflects a single center experience. Other indications for repeat imaging at comprehensive stroke center such as assessment of infarcted core, and presence of large vessel occlusion might still warrant repeat imaging at comprehensive stroke center.

Background: Mechanical thrombectomy (MT) became standard care in 2015 after positive trials in patients presenting with acute ischemic stroke and large vessel occlusion (LVO) 0-6h and in 2018 for selected patients up to 24h from symptom onset. Objective: To evaluate whether patients receiving MT at our center would have comparable outcomes in patients presenting to our comprehensive stroke center (direct) vs transfer patients (drip-and-ship) Methods: This is a retrospective observational study utilising prospectively collected stroke database for patients receiving MT for LVO in anterior and posterior circulation in South Brisbane network of 7 hospitals (6 drip-and-ship centers and 1 MT-capable center), Australia which serves 1.6 million. Day 90 modified Rankin scale (mRS) was used to assess functional outcomes via outpatient follow up at direct or referral center. The association of drip and ship versus mothership treatment with day 90 mRS was tested in ordinal logistic regression adjusted for age, baseline NIHSS and IV thrombolysis. Results: Of 191 patients who underwent Mechanical Thrombectomy from 2015 to June 2018 at our center, 22 patients were excluded from analysis as either their baseline mRS was >1 (13) or follow up data was missing (9). The mean age was 64.4 years. Median (inter-quartile range, IQR) NIHSS was 16 (9-21) on admission and 7 (2-18) on day 1. Thrombolysis in Cerebral Infarction (TICI) ≥2b was achieved in 88.9%. At 90 days, 50.9% achieved excellent functional outcome (mRS 0-1), 61.4% achieved good functional outcome (mRS 0-2) and 69% achieved favorable outcome (mRS 0-3). Median mRS was 1 (IQR 0-5) in 96 patients presenting directly to the endovascular center and 1 (IQR 1-4) in 73 drip-and-ship patients (common odds ratio 1.07 (95%CI 0.62-1.83), p=0.82) Conclusion: Our 7-center network experience confirms real world reproducibility of trial results, interestingly with no difference in functional outcomes for direct vs drip-and-ship patients.

Number Of Passes

BackgroundThe incidence of intracranial atherosclerotic disease (ICAD) in acute ischemic stroke treated with mechanical thrombectomy (MT) is not well defined, and its description may lead to improved stroke devices and rates of first pass success.MethodsA retrospective study was performed on MT patients from 2012 to 2019 at a comprehensive stroke center using chart review and angiogram analysis. Angiograms at the time of MT were reviewed for ICAD, and location and severity were recorded. Patients with ICAD were divided according to ICAD location relative to the large vessel occlusion (LVO) site. Statistical analyses were performed on baseline demographics, comorbidities, MT procedure variables, outcome variables, and their association with ICAD.ResultsOf the 533 patients (mean age 70.4 (SD 13.20) years, 43.5% women), 131 (24.6%) had ICAD. There was no significant difference in favorable discharge outcomes (modified Rankin Scale score of 0–2; 23.8% ICAD vs 27.0% non-ICAD; p=0.82) or groin puncture to recanalization times (average 43.5 (range 8–181) min for ICAD vs 40.2 (4–204) min for non-ICAD; p=0.42). Patients with ICAD experienced a significantly higher number of passes (average 1.8 (range 1–7) passes for ICAD vs 1.6 (1–5) passes for non-ICAD; p=0.0059). Adjusting for age, ≥3 device passes, baseline National Institutes of Health Stroke Scale, rates of angioplasty only, rates of concurrent angioplasty and stenting, coronary artery disease and atrial fibrillation incidences, and time from emergency department arrival to recanalization, yielded no significant difference in rates of favorable outcomes between the two groups.ConclusionPatients who underwent MT with underlying ICAD had similar rates of favorable outcomes as those without, but required a higher number of device passes.

Proven Method

Background: Mechanical thrombectomy (MT) is a proven method of treating patients with acute ischemic stroke (AIS) from a large vessel occlusion. However, there has been controversy regarding the safety and efficacy of incorporating acute intracranial stenting in addition to standard MT especially after the WEAVE trial results which showed a significant increase in stroke and hemorrhage in patients receiving wingspan stenting within 7 days of index ischemic event. We compared the outcomes of all AIS patients treated with acute intracranial stenting + MT versus MT alone. Methods: Through the utilization of a prospectively collected endovascular database at a comprehensive stroke center between 2012-2019, variables such as demographics, co-morbid conditions, symptomatic intracerebral hemorrhage (ICH), mortality rate at discharge, and good/poor outcomes in regard to modified thrombolysis in cerebral infarction score (TICI) and modified Rankin Scale at discharge (mRS dc) were examined. The outcomes between patients receiving acute intracranial stenting + MT and patients that underwent MT alone were compared. Results: There were a total of 439 AIS patients who met criteria for the study (average age 70.38 ± 13.46 years; 45.6% were women). Analysis of 36 patients from the acute stenting + MT group (average age 66.72 ± 13.17 years; 30.6% were women), and 403 patients from the MT Alone group (average age 70.71 ± 13.45 years; 46.9% were women); see Table 1 for baseline characteristics and outcomes. Three patients (8.3%) in the acute stenting + MT group experienced ICH versus forty-four patients (10.9%) in the MT alone group (P=0.631); no significant increases were noted in length of stay (9.08 days vs 9.84 days; P=0.620) or good mRS scores at dc (P=0.636). Conclusion: Acute intracranial stenting in addition to MT was not associated with an increase in ICH rates, overall length of stay, or poor outcome upon discharge of patients. Prospective studies are recommended.
