OBJECTIVEThe role of mechanical thrombectomy in pediatric acute ischemic stroke is uncertain, despite extensive evidence of benefit in adults. The existing literature consists of several recent small single-arm cohort studies, as well as multiple prior small case series and case reports. Published reports of pediatric cases have increased markedly since 2015, after the publication of the positive trials in adults. The recent AHA/ASA Scientific Statement on this issue was informed predominantly by pre-2015 case reports and identified several knowledge gaps, including how young a child may undergo thrombectomy. A repeat systematic review and meta-analysis is warranted to help guide therapeutic decisions and address gaps in knowledge.METHODSUsing PRISMA-IPD guidelines, the authors performed a systematic review of the literature from 1999 to April 2019 and individual patient data meta-analysis, with 2 independent reviewers. An additional series of 3 cases in adolescent males from one of the authors’ centers was also included. The primary outcomes were the rate of good long-term (mRS score 0–2 at final follow-up) and short-term (reduction in NIHSS score by ≥ 8 points or NIHSS score 0–1 at up to 24 hours post-thrombectomy) neurological outcomes following mechanical thrombectomy for acute ischemic stroke in patients < 18 years of age. The secondary outcome was the rate of successful angiographic recanalization (mTICI score 2b/3).RESULTSThe authors’ review yielded 113 cases of mechanical thrombectomy in 110 pediatric patients. Although complete follow-up data are not available for all patients, 87 of 96 (90.6%) had good long-term neurological outcomes (mRS score 0–2), 55 of 79 (69.6%) had good short-term neurological outcomes, and 86 of 98 (87.8%) had successful angiographic recanalization (mTICI score 2b/3). Death occurred in 2 patients and symptomatic intracranial hemorrhage in 1 patient. Sixteen published thrombectomy cases were identified in children < 5 years of age.CONCLUSIONSMechanical thrombectomy may be considered for acute ischemic stroke due to large vessel occlusion (ICA terminus, M1, basilar artery) in patients aged 1–18 years (Level C evidence; Class IIb recommendation). The existing evidence base is likely affected by selection and publication bias. A prospective multinational registry is recommended as the next investigative step.

Anticoagulated Patients

BackgroundAnticoagulated patients (APs) are currently excluded from acute ischemic stroke reperfusion therapy with intravenous recombinant tissue plasminogen activator (IV-rtPA); however, these patients could benefit from mechanical thrombectomy (MT). Evidence for MT in this condition remains scarce. The aim of this study was to analyze the safety and efficacy of MT in APs.MethodsWe analyzed three patient groups from two prospective registries: APs with MT (AP-MT group), non-anticoagulated patients treated with MT (NAP-MT group), and non-anticoagulated patients treated with IV-rtPA and MT (NAP-IVTMT group). Univariate and multivariate logistic regression were used to evaluate treatment efficacy with modified Rankin Scale (mRS) ≤2 and safety (radiologic intracranial hemorrhage (rICH), symptomatic intracranial hemorrhage (sICH) and death rate at 3 months) between groups.Results333 patients were included in the study, with 44 (12%) in the AP-MT group, 105 (31%) in the NAP-MT group, and 188 (57%) in the NAP-IVTMT group. Univariate analysis showed that the AP-MT group was older (P<0.001), more often had atrial fibrillation (P<0001), and had a higher ASPECTS (P<0.006 and P<0.002) compared with the NAP-MT group and NAP-IVTMT groups, respectively. Multivariate analysis showed that the AP-MT group had a lower risk of rICH (OR 2.77, 95% CI 1.01 to 7.61, P=0.05) but a higher risk of death at 3 months (OR 0.26, 95% CI 0.09 to 0.76, P=0.01) compared with the NAP-IVTMT group. No difference was found between the AP-MT and NAP-MT groups.ConclusionsWith regard to intracranial bleeding and functional outcome at 3 months, MT in APs seems as safe and efficient as in NAPs. However, there is a higher risk of death at 3 months in the AP-MT group compared with the NAP-IVTMT group.

Background: Recent recommendations for mechanical thrombectomy (MT) of acute ischemic stroke (AIS) patients with emergent large-vessel occlusions (ELVO) appropriately award top tier evidence (TTE) to the same selective criteria that were employed in recent clinical trials. We sought to evaluate the safety and efficacy of MT in AIS patients with ELVO who fail TTE criteria in a prospective multi-center study. Methods: Data on consecutive AIS patients with ELVO who underwent mechanical thrombectomy were collected from 6 high-volume endovascular centers. Standard safety and efficacy outcomes were compared between patients meeting and failing TTE criteria. Results: TTE criteria for MT were fulfilled in 349 (60%) cases (mean age 63±18 years; 47% men; median admission NIHSS-score 17 points, interquartile range 14-21), whereas 234 (40%) patients did not meet TTE criteria (mean age 62±19 years; 53% men; median admission NIHSS-score 16 points, interquartile range 9-21). (Table 1) The two most common reasons for failing TTE criteria were location of intracranial occlusion (n=144) and treatment window (n=108). In multivariate logistic regression models adjusting for potential confounders cases failing TTE criteria had similar safety (three-month mortality and symptomatic intracranial hemorrhage) and efficacy (three-month functional independence) outcomes with patients meeting TTE. Location of occlusion and proposed time-window according to TTE was also not related to any safety or efficacy outcome. (Table 2) Conclusions: Approximately 40% of AIS patients with ELVO offered MT do not fulfill TTE criteria for MT. Our multi-center experience indicates that MT may be offered to these patients with similar safety and efficacy to ELVO cases meeting TTE. Evidence-based medicine requires that health care providers understand published data and how those data might apply to a given patient’s treatment options. In a changing treatment environment this is a dynamic process.

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.
