Abstract Background: In pediatric arterial ischemic stroke (AIS) clinical treatment trials are lacking and treatment practices variable. Factors determining treatment selection and outcomes are important to delineate. Objective: We aimed to (1) describe acute treatments and outcomes in childhood AIS, and (2) test putative variables for treatment selection, and outcome in a prospective-retrospective multicenter international study. Methods: We evaluated treatments and early outcomes of children enrolled in the International Pediatric Stroke Study with AIS diagnosed at >28 days and <18 years of age from 2003 to 2007. Putative predictor variables for antithrombotic treatment selection included age, clinical AIS subtypes, geographic region (Asia, Australia, Canada, Europe, South America, and U.S.), and diagnosis pre- versus post-2004 (when pediatric AIS guidelines published). Results: Among 676 children with acute AIS, anticonvulsants and antibiotics were administered acutely in 57% and 40%, respectively; use of each decreased with age (P<0.001). Acute anticoagulants (AAC; with/without concomitant anti-platelet therapy) were selected more frequently than either acute anti-platelet agents (AAP) alone or no acute antithrombotic treatment (NAAT) (43% AAC vs. 28% AAP alone and 29% NAAT). NAAT decreased with increasing age. AAC was most frequent in cerebral/cervical arterial dissection (n=52; 75% AAC vs. 6% AAP) and least frequent with moyamoya syndrome (n=72; 31% AC vs. 43% AAP). AAC was most common in Europe and Canada, AAC vs. AAP relatively balanced in the U.S., and AAP most common in Asia and South America. AAC use was similar pre- versus post-2004. At hospital discharge 71% had neurological deficits independent of age, subtype, or geographical region. Mortality at discharge was 3%. Conclusions: Acute anticoagulation is frequently but not uniformly employed in childhood AIS. With current treatment, the prevalence of neurological deficit at hospital discharge is high. These findings reflect disparity in published guidelines and highlight the need for clinical trials to reduce adverse outcomes. Figure 1.

The outcome of children with acute ischemic stroke treated with craniectomy has not been thoroughly examined. In adults, hemicraniectomy after middle cerebral artery territory stroke and posterior decompression after posterior circulation stroke has been shown to improve outcome. Pediatric cases of hemicraniectomy for middle cerebral artery stroke and posterior decompression following posterior circulation stroke suggest relatively good outcome. There are no published data in adults or children with craniectomy after cerebral sinovenous thrombosis. Our aim was to determine the outcome of children with acute ischemic stroke treated with craniectomy in the International Pediatric Stroke Study (IPSS). We included children enrolled who had a craniectomy following stroke presentation. Of 4294 patients in IPSS, 38 children (1%) were found to have craniectomy following an ischemic stroke. Of 38 craniectomy cases, 29 had anterior circulation strokes, 5 had posterior circulation strokes, and 4 had cerebral sinovenous thromboses. The mortality rate was 8%. Overall, children who have craniectomies have significant neurologic deficits. Prospective studies are needed to examine long-term morbidity following craniectomy.

ABSTRACT: Background: Childhood acute arterial ischemic stroke (AIS) is diagnosed at a median of 23 hours post-symptom onset, delaying treatment. Pediatric stroke pathways can expedite diagnosis. Our goal was to understand the similarities and differences between Canadian pediatric stroke protocols with the aim of optimizing AIS management. Methods: We contacted neurologists at all 16 Canadian pediatric hospitals regarding AIS management. Established protocols were analyzed for similarities and differences in eight domains. Results: Response rate was 100%. Seven (44%) centers have an established AIS protocol and two (13%) have a protocol under development. Seven centers do not have a protocol; two redirect patients to adult neurology, five rely on a case-by-case approach for management. Analysis of the seven protocols revealed differences in: 1) IV-tPA dosage: age-dependent 0.75–0.9 mg/kg (N = 1) versus age-independent 0.9 mg/kg (N = 6), with maximum doses of 75 mg (N = 1) or 90 mg (N = 6); 2) IV-tPA lower age cut-off: 2 years (N = 5) versus 3 or 10 years (each N = 1); 3) IV-tPA exclusion criteria: PedNIHSS score <4 (N = 3), <5 (N = 1), <6 (N = 3); 4) first choice of pre-treatment neuroimaging: computed tomography (CT) (N = 3), magnetic resonance imaging (MRI) (N = 2) or either (N = 2); 5) intra-arterial tPA use (N = 3) and; 6) mechanical thrombectomy timeframe: <6 hour (N = 3), <24 hour (N = 2), unspecified (N = 2). Conclusions: Although 44% of Canadian pediatric hospitals have established AIS management pathways, several differences remain among centers. Some criteria (dosage, imaging) reflect adult AIS literature. Canadian expert consensus regarding IV-tPA and endovascular treatment should be established to standardize and implement AIS protocols across Canada.

Introduction: Headache at stroke onset occurs in up to a quarter of adults and is associated with younger age, female gender, right hemisphere and cerebellar infarcts. Little is known about headache at stroke onset in children. Methods: Children (29 days-18 years) with clinical and radiographic confirmation of arterial ischemic stroke were prospectively enrolled in the International Pediatric Stroke Study from 2003-2014. Details regarding demographics, stroke presentation and infarct location were obtained from the multi-center, pediatric stroke registry. Headache at stroke presentation was classified and annotated in the registry by the individual site investigators as present, absent or unclear. Results: We analyzed 2103 children. Half of all subjects ≥ 6 yo reported headache at stroke onset (N=509/1047, 49%; Figure). Headache was less prevalent in children < 6 yo (N=112/1056, 11%; p<0.001), though headache presentation was more commonly classified as unclear (10% vs 32%; p<0.001). In children ≥ 6 yo, headache was significantly associated with papilledema (p = 0.03) and vertigo (p = 0.01), but not with hemiparesis (p = 0.11), visual field deficit (p = 0.90), aphasia (p = 0.35), dysarthria (p = 0.44), or ataxia (p = 0.50). Headache was more common in posterior than anterior circulation infarcts (p<0.001). There was a significant association between headache and right or bilateral hemisphere infarcts (p = 0.04) but not with gender (p = 0.76). Conclusion: Headache is more prevalent in children than adults at stroke ictus and shares similar associations, including infarcts involving the posterior circulation and right hemisphere. Headache may be under-reported in young infants and children due to pre-verbal stages of development. These findings have implications for early identification and treatment of pediatric stroke and warrant further investigation in prospective studies to distinguish stroke from more common benign mimics, including migraine.

ObjectiveTo determine whether lower socioeconomic status (SES) is associated with worse 1-year neurologic outcomes and reduced access to rehabilitation services in children with arterial ischemic stroke (AIS).MethodsFrom 2010 to 2014, the Vascular effects of Infection in Pediatric Stroke (VIPS) observational study prospectively enrolled and confirmed 355 children (age 29 days–18 years) with AIS at 37 international centers. SES markers measured via parental interview included annual household income (US dollars) at the time of enrollment, maternal education level, and rural/suburban/urban residence. Receipt of rehabilitation services was measured by parental report. Pediatric Stroke Outcome Measure scores were categorized as 0 to 1, 1.5 to 3, 3.5 to 6, and 6.5 to 10. Univariate and multivariable ordinal logistic regression models examined potential predictors of outcome.ResultsAt 12 ± 3 months after stroke, 320 children had documented outcome measurements, including 15 who had died. In univariate analysis, very low income (<US $10,000), but not other markers of SES, was associated with worse outcomes (odds ratio [OR] 3.13, 95% confidence interval [CI] 1.43–6.88, p = 0.004). In multivariable analysis, including adjustment for stroke etiology, this association persisted (OR 3.17, 95% CI 1.18–8.47, p = 0.02). Income did not correlate with receiving rehabilitation services at 1 year after stroke; however, quality and quantity of services were not assessed.ConclusionsIn a large, multinational, prospective cohort of children with AIS, low income was associated with worse neurologic outcomes compared to higher income levels. This difference was not explained by stroke type, neurologic comorbidities, or reported use of rehabilitation services. The root causes of this disparity are not clear and warrant further investigation.
