Tenecteplase in Pediatric Stroke: Ready or Not.

BACKGROUND: Intravenous thrombolysis with tissue plasminogen activator is used for off-label treatment of acute childhood stroke. Tenecteplase (TNK) is used to treat acute stroke in adults at many institutions, although there are extremely few data about TNK use in children. We aimed to characterize pediatric stroke experts' experience and preferences with regard to TNK use in children with stroke. METHODS: Online survey distributed to members of the International Pediatric Stroke Organization in April 2023. RESULTS: We received 33 responses. Most (81.2%) respondents reported only being "a little familiar" or "somewhat familiar" with TNK. Only six (18%) respondents reported being "familiar" or "very familiar" with TNK. Seventy percent of respondents were willing to treat pediatric stroke with TNK, at least in some situations. In a hypothetical scenario of a child in an outside emergency room with only TNK available, 81.8% would consider recommending treatment with TNK. However, only three (9.1%) respondents had TNK in their stroke protocol and seven (21.2%) had TNK on formulary at their hospital. Two respondents reported direct awareness of a child treated with TNK. CONCLUSIONS: The majority of pediatric stroke neurologists responding to this survey reported a willingness to consider TNK use in children. However, data on TNK use in children, provider experience, and pediatric hospital preparedness are limited.

Epidemiology of COVID-19 in Infants in the United States: Incidence, Severity, Fatality, and Variants of Concern.

BACKGROUND: The clinical spectrum of infant COVID-19 ranges from asymptomatic infection to life-threatening illness, yet epidemiologic surveillance has been limited for infants. METHODS: Using COVID-19 case data (restricted to reporting states) and national mortality data, we calculated incidence, hospitalization, mortality and case fatality rates through March 2022. RESULTS: Reported incidence of COVID-19 was 64.1 new cases per 1000 infant years (95% CI: 63.3-64.9). We estimated that 594,012 infants tested positive for COVID-19 nationwide by March 31, 2022. Viral variant comparisons revealed that incidence was 7× higher during the Omicron (January-March 2022) versus the pre-Delta period (June 2020-May 2021). The cumulative case hospitalization rate was 4.1% (95% CI: 4.0%-4.3%). For every 74 hospitalized infants, one infant death occurred, but overall COVID-19-related infant case fatality was low, with 7.0 deaths per 10,000 cases (95% CI: 5.6-8.7). Nationwide, 333 COVID-19 infant deaths were reported. Only 13 infant deaths (3.9%) were the result of usually lethal congenital anomalies. The majority of infant decedents were non-White (28.2% Black, 26.1% Hispanic, 8.1% Asian, Indigenous or multiracial). CONCLUSIONS: More than half a million US infants contracted COVID-19 by March 2022. Longitudinal assessment of long-term infant SARS-CoV-2 infection sequelae remains a critical research gap. Extremely low infant vaccination rates (<5%), waning adult immunity and continued viral exposure risks suggest that infant COVID-19 will remain a persistent public health problem. Our study underscores the need to increase vaccination rates for mothers and infants, decrease viral exposure risks and improve health equity.

Investigating the effectiveness of oral ketamine on pain, mood and quality of life in treatment resistant chronic pain.

Introduction: Chronic pain is defined as pain lasting longer than 3 months. This often causes persistent emotional distress and functional disability that is refractory to conventional treatments. Emerging evidence suggests that oral Ketamine therapy may have a specific role in managing treatment-resistant chronic pain. This study aimed to assess the effectiveness of oral ketamine within a tertiary chronic pain management clinic. Methods: This study was a clinic-based retrospective descriptive study of 79 patients with a broad range of chronic pain diagnoses and treated with oral ketamine over a period up to 12 years. Changes in pain, mood and quality of life (QoL) were assessed using a numerical pain severity score, the Brief Pain Inventory (BPI), the Public Health Questionnaire (PHQ-9) and American Chronic Pain Association Quality of Life (QoL) scale. Results: 73 patients were accessible for follow-up (mean daily dose and treatment duration were 193.84 mg and 22.6 months respectively). Pain scores decreased (p < 0.0001) on both numerical scores (41.6% decrease) and BPI scoring (mean decrease 2.61). Mood improved (p < 0.0001) across both PHQ-9 and BPI measurements. Patients also reported less difficulty with daily activities and improved QoL. The most common adverse reaction was drowsiness (21.9%), with 30.1% reporting no adverse reactions from Ketamine. Discussion: This work adds to the growing body of evidence that under the supervision of a pain specialist, oral ketamine therapy may be a safe, tolerable and effective treatment for chronic pain conditions which have not responded to other management options. Further research is required to produce a more accurate understanding of its chronic use. Key message: This real-world study shows that patients being treated with oral ketamine for chronic pain report decreased severity of pain, improved mood and increased quality of life across all conditions.

Epidemiology, causes, and morbidities of stroke in the young.

PURPOSE OF REVIEW: The purpose is to describe the latest research on epidemiology, causes, and morbidities of stroke in neonates and children. RECENT FINDINGS: The global incidence of childhood stroke is approximately 2 per 100 000 person-years, which is significantly lower compared to neonates (20-40 per 100 000 live births) and adults (80-90 per 100 000 person-years). Placental abnormalities are a risk factor for perinatal stroke, although cause is usually multifactorial. In children, nonatherosclerotic arteriopathies and arteriovenous malformations are major causes of ischemic and hemorrhagic strokes, respectively. The perinatal period confers a high risk of stroke and can lead to long-term disability, including motor delay, cognitive or speech impairment, and epilepsy. Recent studies suggest that at least 50% of survivors of perinatal stroke have abnormal neurodevelopmental scores in long-term follow up. Childhood stroke is associated with significant morbidity, including epilepsy, motor impairments, and behavioral disability. Recent studies have also identified an association between pediatric stroke and behavioral disorders, such as attention deficit hyperactivity disorder and autism. SUMMARY: Perinatal and childhood strokes are important causes of neurological morbidity. Given the low incidence of childhood stroke, prospective research studies on epidemiology, causes, and outcomes remain limited, highlighting the need for continued multisite collaborations.

Development and Evaluation of a Child Neurology Resident Curriculum for Communication Around Serious Illness.

Background: Communication around serious illness is a core competency for all residencies. One-fifth of neurology residencies have no curriculum. Published curricula use didactics or role-play to assess confidence performing this skill without evaluation in clinical settings. The SPIKES mnemonic (Setting, Perception, Invitation, Knowledge, Empathy, Strategy/Summary) outlines 6 evidence-based steps for communication around serious illness. It is unknown whether child neurology residents can incorporate SPIKES into communication around serious illness in clinical settings. Objective: To develop and evaluate a curriculum on communication around serious illness using SPIKES for child neurology residents that shows long-term skill retention in clinical settings at a single institution. Methods: In 2019, we created a pre-post survey and skills checklist based on SPIKES, with 20 total including 10 core skills. Faculty observed residents' (n = 7) communication with families and completed both preintervention and postintervention checklists for comparison. Residents underwent training in SPIKES during a 2-hour session using didactic and coached role-play. Results: All (n = 7) residents completed preintervention surveys, 4 of 6 completed postintervention. All (n = 6) participated in the training session. Following the training, 75% of residents reported improved confidence in use of SPIKES, though 50% were still unsure about appropriately responding to emotions. There was improvement in all SPIKES skills, with significant improvement in 6 of 20 skills up to 1 year following training. Conclusion: This is the first evaluation of the implementation of a communication around serious illness curriculum for child neurology residents. We identified improved comfort with SPIKES after training. Successful acquisition and utilization of this framework in our program suggests it could be incorporated into any residency program.

Tenecteplase in Acute Stroke: What About the Children?

Tenecteplase is replacing alteplase as the fibrinolytic agent of choice for the acute management of ischemic stroke in many adult stroke centers due to practical and pharmacokinetic advantages in the setting of similar outcomes. Although thrombolytic use is increasing for acute childhood stroke, there is very limited experience with tenecteplase in children for any indication, and importantly, there are no data on safety, dosing, or efficacy of tenecteplase for childhood stroke. Changes in fibrinolytic capacity over childhood, pediatric pharmacological considerations such as age-specific differences in drug clearance and volume of distribution, and practical aspects of drug delivery such as availability in children's hospitals may impact decisions about transitioning from alteplase to tenecteplase for acute pediatric stroke treatment. Pediatric and adult neurologists should prepare institution-specific guidelines and organize prospective data collection.

Cerebral Arteriopathies of Childhood - Current Approaches.

Up to more than half of previously healthy children presenting with their first arterial ischemic stroke have a cerebral arteriopathy. Cerebral arteriopathies during childhood can be congenital, reflecting abnormal vessel development, or acquired when caused by disruption of vascular homeostasis. Distinguishing different types of cerebral arteriopathies in children can be challenging but of great clinical value as they may dictate different disease and treatment courses, and clinical and radiologic outcomes. Furthermore, children with stroke due to a specific arteriopathy exhibit distinctive features when compared to those with stroke due to other causes or a different type of arteriopathy. These features become crucial in the management of pediatric stroke by choosing appropriate diagnostic and treatment strategies. The objective of this article is to provide the reader with a comprehensive up-to-date review of the classification, symptoms, diagnosis, treatment, and outcome of cerebral arteriopathies in children.

Thalamic Volume Loss Is Greater in Children Than in Adults Following Middle Cerebral Artery Territory Arterial Ischemic Stroke.

Background: Younger stroke patients may suffer worse outcomes than older patients; however, the extent to which age at stroke impacts remote areas of the brain remains unclear. The objective of this study was to determine thalamic volume changes ipsilateral to middle cerebral artery territory strokes based on age at acute ischemic stroke onset. Methods: Acute ischemic stroke patients <9 years, 9-18 years, and >18 years old were retrospectively recruited from a large quaternary care system. Each subject underwent an acute (<72 hours from AIS) and chronic (>90 days) magnetic resonance imaging (MRI) scan. Manual thalamic segmentation was performed. Results: Younger and older children had significantly greater stroke-side thalamic volume loss compared to adults (48.2%, P = .022; 40.7%, P = .044, respectively). Conclusions: Stroke-side thalamic volumes decreased across the age spectrum but to a greater degree in pediatric patients. This observation can affect functional and cognitive outcomes post stroke and warrants further research.

Biomarkers of pre-pregnancy allostatic load and subsequent adverse birth outcomes.

Racial disparities in birth outcomes are seemingly intractable. Using person-centered methods and drawing from the life course and Weathering Hypothesis literatures, we used data from the National Longitudinal Study of Adolescent to Adult Health to group non-Hispanic White and non-Hispanic Black women ages 24-34 into latent classes based on pre-pregnancy biomarkers of allostatic load. Stratified analyses yielded four latent classes among non-Hispanic White women, characterized by: 1) high blood pressure, 2) high body mass index and waist circumference, 3) high total cholesterol and triglycerides, and low high-density lipoprotein, and 4) low-risk, and two latent classes among non-Hispanic Black women, characterized by: 1) high body mass index and waist circumference, and moderate-risk blood pressure, hbA1c, and c-reactive protein, and 2) low-risk. Allostatic load class membership and other maternal- and infant-level covariates were then included simultaneously as predictors of three separate dichotomous outcomes: preterm birth, macrosomia, and low birth weight in multilevel logistic regression models. In a separate multilevel linear regression model, the same variables were simultaneously entered to predict continuously measured birthweight. In multilevel, multivariate models, White women in the high-risk body mass index and waist circumference class, as compared to the high-risk blood pressure class, had infants with higher birthweights. Other comparisons were not significant or not of meaningful magnitude. Prioritizing temporality so that allostatic load measurement preceded first birth likely biased the composition of the analytical sample. Additional research is needed to help medical providers and public health practitioners understand the complex biological and social mechanisms underlying inequities in birth outcomes and identify prevention strategies.

Optimization and Characterization of a Bone Culture Model to Study Prostate Cancer Bone Metastasis.

Nearly 90% of patients with advanced prostate cancer manifest bone metastases. Distinct from the osteolytic metastasis mostly observed in other cancer types, prostate cancer bone metastasis is typically more osteoblastic, which is relatively understudied due to the lack of reliable and efficient models to resemble the indolent cellular growth and complexity of metastatic progression. In our previous studies, we developed bone-in-culture array (BICA) to primarily model the osteoblast-involved, pre-osteolytic stage of breast cancer bone metastasis. Given that the progression of prostate cancer bone metastasis is largely osteoblastic, it is reasonable to speculate that the original BICA model can be adjusted to investigate prostate cancer bone metastases. In this study, we refined BICA by reducing the surgical labor and improving its reproducibility and capacity. The optimized BICA can successfully recapitulate important features of prostate cancer bone metastasis such as the osteoblastic phenotype, indolent growth, cancer-niche interactions, and response to hormones. Our efforts address the long-standing need for reliable and efficient models to study prostate cancer bone metastasis.

A 14-year-old Girl with Right-Sided Weakness and Speech Difficulty.

We herein report a case of Childhood Primary Central Nervous System (CNS) Angiitis. This case consisted of a 14-year-old girl who presented with right-sided weakness, aphasia, and a fever. A Magnetic Resonance Imaging of the brain showed multifocal areas of ischemia. Magnetic Resonance Angiography of the head and neck showed narrowing and irregularities of the left middle cerebral artery and right posterior cerebral artery. Cerebrospinal Fluid studies showed a lymphocytic pleocytosis and brain biopsy revealed leptomeningeal and perivascular inflammation. The epidemiology, presenting symptoms, work-up, pathophysiology, diagnostic criteria, and treatment of Childhood Primary CNS angiitis are discussed. This case serves as a reminder that when pediatric patients present with stroke-like symptoms inflammatory etiologies including Primary CNS Angiitis must be considered and treated appropriately in a time sensitive manner.

Media representation, perception and stigmatisation of race, sexuality and HIV among young black gay and bisexual men.

Young Black gay and bisexual men who have sex with men experience stigma related to race, gender expression, sexuality and HIV status. Stigma impacts access to HIV care and prevention as well as interactions with healthcare providers. The amplification of stigma through popular media is under-researched in the health sciences. HealthMpowerment is a mobile phone optimised intervention to reduce sexual risk and support community-building for young Black gay and bisexual men (age 18-30). We analysed Forum conversations from 48 participants, 45.8% living with HIV. Of 322 stigma-relevant conversations, 18.9% referenced the media (e.g. television, news, social media) as a source of stigma. Forum conversations covered media representations of Black gay and bisexual men, media's influence on identity, and the creation of stigma by association with media representations. Cultural messages embedded in the media may accentuate stereotypes that influence perceptions of Black gay and bisexual men and disregard intersectional identities. HealthMpowerment provided a space to challenge stigmatising representations. Participants used HealthMpowerment to garner social support and celebrate positive media representations. Interventions for young Black gay and bisexual men should consider the influential role of media and include spaces for participants to process and address stigma.

Medical encounters at community-based physical activity events (parkrun) in the UK.

OBJECTIVE: To determine the incidence, clinical correlates and exposure risk of medical encounters during community-based physical activity events in the UK. METHODS: An analysis of medical data from weekly, community-based physical activity events (parkrun) at 702 UK locations over a 6-year period (29 476 294 participations between 2014 and 2019) was conducted in order to define the incidence and clinical correlates of serious life-threatening, non-life-threatening and fatal medical encounters. RESULTS: 84 serious life-threatening encounters (overall incidence rate=0.26/100 000 participations) occurred including 18 fatalities (0.056/100 000 participations). Statistical modelling revealed that the probabilities of serious life-threatening encounters were exceptionally low, however, male sex, increasing age, slower personal best parkrun time and less prior running engagement/experience (average number of runs per year and number of years as a parkrun participant) were associated with increased probability of serious life-threatening encounters. These were largely accounted for by cardiac arrest (48/84, 57%) and acute coronary syndromes (20/84, 24%). Non-life-threatening medical encounters were mainly attributed to tripping or falling, with a reported incidence of 39.2/100 000 participations. CONCLUSIONS: Serious life-threatening and fatal medical encounters associated with parkrun participation are extremely rare. In the context of a global public health crisis due to inactivity, this finding underscores the safety and corollary public health value of community running/walking events as a strategy to promote physical activity.

Daytime and nocturnal activity in treated dogs with idiopathic epilepsy compared to matched unaffected controls.

BACKGROUND: In dogs, antiepileptic drugs (AED) cause lethargy but quantitative data regarding the effects of AED on activity levels are not available, and little is known about how AEDs affect sleep quality. OBJECTIVE: To quantitatively compare activity levels and nocturnal activity in dogs previously diagnosed with idiopathic epilepsy (IE) receiving AEDs compared to age- and breed-matched control dogs. ANIMALS: Sixty-two dogs with IE and 310 control dogs. METHODS: This is a 3-month prospective parallel observational study. An activity monitoring device for dogs was used to measure daily activity levels and sleep scores in all dogs. RESULTS: Dogs with IE treated with AEDs had an 18% average lower baseline activity level compared to control dogs (P = .005; point estimate = 0.82, 95% confidence interval [CI], 0.75-0.90). The combination of phenobarbital and potassium bromide (KBr) was associated with an average 28% decrease in activity in dogs with IE compared to control dogs (P = .03; point estimate = 0.72; CI, 0.62-0.82). Mean sleep scores were not significantly different in dogs with IE receiving AEDs compared to control dogs (P = .43). However, higher dosages of KBr were associated with lower sleep scores (P = .01). CONCLUSIONS: Dogs with IE receiving AEDs have lower activity levels, but no difference in sleep scores, compared to controls. The combination of phenobarbital and KBr had the largest decrease in activity between groups. Higher doses of KBr may affect nocturnal activity in epileptic dogs.

Building Community in the HIV Online Intervention Space: Lessons From the HealthMPowerment Intervention.

BACKGROUND: Mobile health platforms can facilitate social support and address HIV (human immunodeficiency virus) stigma but pose challenges for intervention design and participant engagement. Giddens's structuration theory, that individuals are shaped by-and shape-their communities through rules and resources that give them power to operate within these environments, provides a useful analytic framework for exploring these dynamic intervention spaces. METHOD: Data were drawn from an online randomized controlled trial intervention (HealthMpowerment) for young Black men who have sex with men to reduce condomless anal intercourse. We applied a conversational analysis informed by structuration theory to 65 user-generated conversations that included stigma content. We aimed to understand how the interdependent relationship between the intervention space and participants' contributions might contribute to behavior change. RESULTS: Thirty five intervention participants contributed to the analyzed conversations. Our analysis identified three types of conversational processes that may underlie behavior change: (1) Through intervention engagement, participants established norms and expectations that shaped their discussions; (2) participants used anecdotes and anonymity to reinforce norms; and (3) intervention staff members sought to improve engagement and build knowledge by initiating discussions and correcting misinformation, thus playing an integral role in the online community. CONCLUSIONS: The lens of structuration theory usefully reveals potential behavior change mechanisms within the social interactions of an online intervention. Future design of these interventions to address HIV stigma should explicitly characterize the context in which individuals (study staff and participants) engage with one another in order to assess whether these processes are associated with improved intervention outcomes.

Higher-Quality Data Collection Is Critical to Establish the Safety and Efficacy of Pediatric Mechanical Thrombectomy.

BACKGROUND AND PURPOSE: Because children often have lifelong morbidity after stroke, there is considerable enthusiasm to pursue mechanical thrombectomy in childhood stroke based on literature reports. However, current published data may reflect inconsistent reporting and publication bias, which limit the ability to assess safety and efficacy of mechanical thrombectomy in childhood stroke. METHODS: This retrospective cohort study compared reporting quality and clinical outcomes for mechanical thrombectomy between a trial-derived cohort of 42 children treated with mechanical thrombectomy for acute stroke at study sites and 133 patients reported in the literature. National Institutes of Health Stroke Scale at baseline, 24 hours after mechanical thrombectomy, and at discharge were compared between study site patients and literature patients. Odds ratios (ORs) were used to compare reporting frequencies. Proportional odds logistic regression was used to compare outcomes. RESULTS: Premechanical thrombectomy National Institutes of Health Stroke Scale was available in 93% of study patients compared with 74% of patients in the literature (OR, 4.42 [95% CI, 1.47-19.89]). Postmechanical thrombectomy National Institutes of Health Stroke Scale was available in 69% of study patients compared with 29% of literature cases at 24 hours (OR, 5.48 [95% CI, 2.62-12.06]), and 64% of study patients compared with 32% of cases at discharge (OR, 3.85 [95% CI, 1.87-8.19]). For study sites, median scores were 12 at baseline, 9 at 24 hours, and 5 at discharge. Median scores in case reports were 15 at baseline, 4 at 24 hours, and 3 at discharge. ORs for differences in outcomes between groups were 5.97 (95% CI, 2.28-15.59) at 24 hours and 3.68 (95% CI, 1.45-9.34) at discharge. CONCLUSIONS: Study site patients had higher rates of National Institutes of Health Stroke Scale reporting and worse short-term outcomes compared with literature reports. Rigorous data collection is needed before treatment guidelines for pediatric mechanical thrombectomy can be developed.

Altered supraspinal motor networks in survivors of poliomyelitis: A cortico-muscular coherence study.

OBJECTIVE: Poliomyelitis results in changes to the anterior horn cell. The full extent of cortical network changes in the motor physiology of polio survivors has not been established. Our aim was to investigate how focal degeneration of the lower motor neurons (LMN) in infancy/childhood affects motor network connectivity in adult survivors of polio. METHODS: Surface electroencephalography (EEG) and electromyography (EMG) were recorded during an isometric pincer grip task in 25 patients and 11 healthy controls. Spectral signal analysis of cortico-muscular (EEG-EMG) coherence (CMC) was used to identify the cortical regions that are functionally synchronous and connected to the periphery during the pincer grip task. RESULTS: A pattern of CMC was noted in polio survivors that was not present in healthy individuals. Significant CMC in low gamma frequency bands (30-47 Hz) was observed in frontal and parietal regions. CONCLUSION: These findings imply a differential engagement of cortical networks in polio survivors that extends beyond the motor cortex and suggest a disease-related functional reorganisation of the cortical motor network. SIGNIFICANCE: This research has implications for other similar LMN conditions, including spinal muscular atrophy (SMA). CMC has potential in future clinical trials as a biomarker of altered function in motor networks in post-polio syndrome, SMA, and other related conditions.

Pediatric Acute Stroke Protocol Implementation and Utilization Over 7 Years.

OBJECTIVE: To examine the implementation and utilization of a pediatric acute stroke protocol over a 7-year period, hypothesizing improvements in protocol implementation and increased protocol use over time. STUDY DESIGN: Clinical and demographic data for this retrospective observational study from 2011 through 2018 were obtained from a quality improvement database and medical records of children for whom the acute stroke protocol was activated. The initial 43 months of the protocol (period 1) were compared with the subsequent 43 months (period 2). RESULTS: Over the 7-year period, a total of 385 stroke alerts were activated, in 150 children (39%) in period 1 and 235 (61%) in period 2, representing a 56% increase in protocol activation. Stroke was the final diagnosis in 80 children overall (21%), including 38 (25%) in period 1 and 42 (19%) in period 2 (P = .078). The combined frequency of diagnosed stroke, transient ischemic attack (TIA), and other neurologic emergencies remained stable across the 2 time periods at 39% and 37%, respectively (P = .745). Pediatric National Institutes of Health Stroke Scale (PedNIHSS) documentation increased from 42% in period 1 to 82% in period 2 (P < .001). Magnetic resonance imaging (MRI) was the first neuroimaging study for 68% of the children in period 1 vs 78% in period 2 (P = .038). All children with acute stroke received immediate supportive care. CONCLUSIONS: Pediatric stroke protocol implementation improved over time with increased use of the PedNIHSS and use of MRI as the first imaging study. However, with increased utilization, the frequency of confirmed strokes and other neurologic emergencies remained stable. The frequency of stroke and other neurologic emergencies in these children affirms the importance of implementing and maintaining a pediatric acute stroke protocol.

What is the Role of Mechanical Thrombectomy in Childhood Stroke?

BACKGROUND: Like adults, most children have lifelong morbidity after stroke. Revascularization therapies such as intravenous tissue plasminogen activator and mechanical thrombectomy may be options to decrease this morbidity in selected children, although currently there are no evidence-based recommendations to guide treatment. The utility and safety of mechanical thrombectomy in childhood stroke is unknown because of the lack of safety trials, case-controlled trials, and comprehensive retrospective studies. As such, the current rationale for the use of mechanical thrombectomy in childhood is based on extrapolation from adult experience, as well as consensus at individual institutions with many centers deciding care on a case-by-case basis. Nevertheless, the increasing use of recanalization therapies in appropriately selected adults with acute arterial ischemic stroke has led to an increase in consideration and use in childhood, and there are enough case reports and series, as well as experience, to suggest that some children with large vessel occlusion will likely benefit. METHODS: We reviewed current literature regarding mechanical thrombectomy in childhood. RESULTS: There are differences between pediatric and adult stroke which may impact safety, efficacy, and individual decision-making, including patient size, pathophysiology of stroke, deficit, experience, and lack of data regarding natural history of stroke in children. CONCLUSIONS: Hospitals planning to perform mechanical thrombectomy in children should establish local procedures and guidelines for considering thrombectomy. In our experience, care is best provided through multidisciplinary teams including a pediatric vascular neurologist, neurointerventionalist with pediatric experience, and pediatric neurocritical care.
