Introduction. Reducing management delays until revascularization in acute arterial ischemic stroke (AIS) is critical to improve outcomes, yet the determinants of such delays have not been reported in children. Hypothesis. We explored the determinants of delay between last-known-well (LKW) and initiation of recanalization treatment in children. Methods. This is an ancillary study of the national French KidClot study, which included consecutive pediatric patients with AIS and recanalization treatment (IV thrombolysis IVT and/or mechanical thrombectomy MT) from January 1, 2015 to May 31, 2018. We assessed the effect of i) pre-hospital triage (i.e. dispatching considering a potential stroke), ii) direct admission to a tertiary care center versus need for transfer, and iii) management in a pediatric vs adult unit on the delay from LKW to recanalization treatment, as well as on clinical outcomes (mRS at 1 year). Results 68 children were included, treated with IVT alone (n=31), MT alone (n=23), or combined IVT+MT (n=14). Median age was 11 years old [IQR 4-16] and initial PedNIHSS 13 [IQR 7-19]. Prehospital triage demonstrated a significant role in reducing LKW to first recanalization treatment delay (229 vs. 270 min, p=0.01), especially for delays to MT (p&lt;0.001). No significant effect on treatment delay was associated with direct vs secondary admission to a tertiary care center, or management in an adult vs pediatric unit (although a tendency towards shorter delay to MT was observed in adult units: 370 vs 437 min, p=0.06). Prehospital triage was significantly associated with favorable outcome, with a shift towards lower mRS categories (p=0.021) despite similar presentation severity. Conclusions In children with AIS, prehospital triage seems to be the most significant factor associated with shorter recanalization treatment delays, and better outcomes in treated patients. These results present a major incentive to improve the prehospital part of pediatric stroke codes.

Introduction: We present a case series of 5 children with spinal cord infarction (SCI). Our objectives are to study the clinical presentation, MRI findings, etiology, risk factors and treatment options for pediatric SCI. Methods: Descriptive analyses of 5 pediatric patients with SCI. Results: Median age was 8 years (range 0.2-15). There were 2 males and 3 females. 3 patients presented with lower extremity weakness (bilateral in 2, unilateral in 1) and 2 with hemiplegia. Pain was reported in 2 patients (back pain in 1, neck/shoulder pain in 1). MRI showed infarction involving thoracic spine in 3, cervical spine in 1, and cervical and thoracic spine in 1 patient. Notably, imaging was initially negative in 2 patients, with infarct visible on follow-up imaging 3-5 days later (Figure 1). Suspected etiologies included vascular malformation versus hemorrhagic infarct in 1, rotational arteriopathy in 1, and fibrocartilaginous embolism in 3 patients. Thrombosis was not found in any patient. Treatment was mainly supportive, though 2 patients received pulse steroids during the initial diagnostic period. 3 patients were started on prophylactic aspirin. At 3 months follow up, 4 patients had improved, with 1 asymptomatic, 3 ambulatory with mild to moderate deficits; 1 patient had spastic diplegia. Discussion/Conclusion: Pediatric SCI is mostly idiopathic. In our series, fibrocartilaginous embolism ,rotational arteriopathy, and vascular malformation were suspected etiologies. Thrombotic disorders have been associated with SCI, though none was found here. Sudden pain and neurological deficits can be presenting features. MRI was essential for diagnosis and follow-up. Thrombotic, infectious, and vessel-imaging work-up were required to evaluate the etiology. Treatment is mainly supportive. The utility of antiplatelet agents in idiopathic SCI is unclear. The outcome appears encouraging with all except one patient improved or recovered on follow-up.

In this study, the impact of Cerebral Blood Flow (CBF) in non-ischemic brain regions is analyzed measure stroke severity. The hippocampus is a complex brain structure in the temporal lobe and plays a role in learning, memory and spatial navigation. Monitoring hippocampal CBF after AIS may help in understanding its role in childhood development, and allowing for stroke outcome predictions. CBF within the ipsilesional (stroke hemisphere) and contralesional (non-stroke hemisphere) hippocampi was assessed and associated with neurological and sensorimotor deficits observed at acute, subacute (3-7 days post-stroke) and chronic (3 months post-stroke) phases of stroke recovery. Nine pediatric stroke patients (mean age 14.89 ± 2.85, 4 Male) with unilateral, non-hippocampal stroke lesions were scanned using arterial spin labelling MRI in a 3T Siemens MRI scanner with a 2D pulsed labeling scheme. Neurological outcome was evaluated with the Pediatric Stoke Outcome Measure (PSOM) at 3-7 days and at 3 months post-stroke. Mean CBF at the hippocampi were compared to seven healthy controls (mean age 14.53 ± 1.43, 2 Male). Mean CBF (mL/100g/min) in the ipsilesional and contralesional hippocampi were 52.77 ± 10.98 and 54.69 ± 14.24 respectively. Mean CBF in the control group was found to be greater at 61.14 ± 12.30. ANOVA between groups revealed an F-statistic of F=1.24 (p=0.30) and a post hoc one tailed t-test between the ipsilesional and control group yielded a t-statistic of t=1.55 (p=.067). A negative correlation of ρ=-0.77 (p=.025) was observed between CBF ratios in intrasubject hippocampi and the PSOM score observed at the acute timepoint. CBF ratios against PSOM score at three months post-stroke showed a Spearman coefficient of ρ=-0.96 (p<<.001). Intrasubject CBF between hippocampi at the acute timepoint was found to be a strong indicator of neurological and sensorimotor deficits at three months ponths post-stroke. A larger sample size is required to determine validity.

INTRODUCTION Acute ischemic stroke (AIS) remains as a significant cause of neurological impairment and ranks as one of the top ten causes of death in childhood. While current research has revealed new treatment practices, risk factors, and neurological outcomes, there remains a gap in our understanding of the mechanisms of stroke in the developing brain, as well as limited therapies, especially beyond the perinatal or neonatal period. The photothrombotic 'ring' model causes ischemic damage within a given cortical area by photochemically induced platelet occlusion of cortical vasculature. Using this technique facilitates reproducible infarction sizes with delineated boundaries for precise lesion characterization. When considering treatment for AIS, use of HMG-CoA reductase inhibitors (statins) are a potential candidate. This study aims to longitudinally assess stroke and BBB damage following use of a statin in a juvenile photothrombotic rat stroke model using quantitative MRI. METHODS A photothrombotic stroke was induced in 10 male Sprague Dawley rats. 5 rats received 20 ml/kg of Atorvastatin and 5 rats received no treatment. Quantitative MRI (T2W, DWI, DCE) was performed at Day 0, 2, 7 on all rats using a 3T MRI system. 3D slicer was used to analyze the T2W images. The lesion was segmented for each slice to calculate lesion volume. Apparent diffusion coefficient (ADC) maps were created from DWI images and values were calculated for the lesion, penumbra, and control area. Permeability maps were generated from DCE images using the Patlak model and values were calculated within the lesion and control area. Student's t-tests, Benjamini-Hochberg corrected for multiple comparisons with an α level of 0.05, were conducted to compare both groups. RESULTS The measured T2W lesion volume was significantly reduced in the statin group on day 2 (p = 0.048) and 7 (p = 0.028) following AIS. ADC and BBB values showed no significant changes between groups over time.

Introduction In Nigeria and sub-Saharan Africa, the commonest cause of strokes in childhood is sickle cell disease. Focal cerebral arteriopathy (FCA) accounts for up to 12% of paediatric strokes but is relatively under-diagnosed and under-reported in this part of the world. We report a case in a 4 year old girl. Case history A previously healthy 4 year old girl presented with a day's history of vomiting, left sided focal seizures and subsequent weakness of the left upper and lower limbs. Her haemogblobin phenotype is A. There was no antecedent history of a rash, fever, cough or coryza. Clinical examination revealed a moderately dehydrated young girl, with a left upper motor neurone facial nerve palsy, left sided hypotonia, hyper-reflexia and reduced power. A diagnosis of a right hemispheric cardiovascular accident of unknown cause was made. Clotting profile and full blood count iwere normal. Electrolytes, urea and creatinine were also normal. Fasting lipid profile was also within normal limits. Echocardiography was normal. Cranial CT revealed extensive acute right cerebral infarct in the right MCA & PCA territories (Figure 1). Brain MRI revealed extensive acute right cerebral infarct in the right MCA & PCA territories likely due to right ICA occlusion (Figure 2). MRA TOF as well as volume rendered images showed non-visualization of the ICA on the right with some signal intensity noted in the right MCA presumably from collateral flow from both ACA (Figure 3). Patient had aspirin and prednisolone, and commenced physiotherapy. Power gradually increased to 3+ in the left upper limb and 4 in the left lower limb. She has continued to improve. Conclusion Sickle cell disease is not the only cause of childhood ischaemic stroke in our region. FCA should be considered. Prognosis is favourable even in our setting.

Objective: To describe patterns of ischemic infarction in cases of acute hydrocephalus. Methods: Authors identified recent cases from their institutions and shared clinical descriptors. Brief case reports and imaging findings are described below. Case 1: A 12 month old with dandy walker malformation and ventriculoperitoneal shunt presented for new onset seizures and altered mental status. Magnetic resonance imaging demonstrated worsening hydrocephalus and the patient went to the operating room for emergent shunt revision. Post-operative MRI the following day demonstrated watershed, posterior cerebral artery, and cerebellar infarctions (Figure 1) Case 2: A 16 year old male with a history of ventriculoperitoneal shunt and epilepsy presented in status epilepticus. MRI confirmed shunt failure and the patient was emergently taken to OR for hydrocephalus. He had delayed recovery after shunt revision, and MRI demonstrated posterior cerebral artery and cerebellar infarctions (Figure 2) Case 3: A 2 year old male with achondroplasia developed sudden onset confusion and lethargy. Emergent magnetic resonance imaging demonstrated acute hydrocephalus, as well as infarction in the occipital lobe and cerebellar hemispheres. After ventriculoperitoneal shunt placement, he had no further infarction (Figure 3). Conclusion: Acute hydrocephalus, associated with increased intracranial pressure, is associated with posterior cerebral artery and cerebellar infarction. The exact mechanism of infarction is unclear. We propose posterior cerebral artery infarctions may be mediated from tentorium cerebelli impinging on the posterior cerebral arteries. Cerebellar infarcts may also be mediated by a similar mechanism.

Spinal cord infarction is difficult to diagnose in pediatrics, especially given symptomatic overlap with demyelinating/neuroinflammatory disease and its low incidence. Typical presentations involve acute, progressive loss of function at corresponding spinal levels, though autonomic symptoms are not well described in children. Here, we describe a pediatric patient presenting with neurogenic shock due to acute traumatic spinal cord infarction attributed to fibrocartilaginous emboli (FCE). A 10-year-old female presented after being found on the floor. She recalled a neck hyperextension-hyperflexion event while cheerleading the night prior. Hours later, she developed bilateral hand weakness and paresthesias in all extremities. In the morning, she fell when walking and could not get up. Initial vitals revealed hypothermia, normocardia, and hypotension requiring vasoactives. Head CT was normal. She was admitted to ICU for presumed urosepsis given pyuria. Neurologic exam was notable for intact mentation and sensation, 0/5 distal upper extremity (UE) strength in all modalities, UE areflexia, 3/5 proximal UE strength, and 4/5 lower extremity strength with intact reflexes. Spinal MRI revealed traumatic disc protrusion at C3-C4 and C4-C5 with associated edema; DWI showed diffusion restriction from C3-C7 suggestive of acute infarct from FCE. CSF evaluation was unrevealing for neuro-inflammation. She was later discharged to inpatient rehab. The incidence of neurogenic shock in cervical spinal cord injury has been reported at 29%, though it is unclear if incidence is higher among patients with cord ischemia. In the acute setting, other differentials, such as acute flaccid myelitis or transverse myelitis, can also present with vital signs that may be interpreted as dysautonomia rather than neurogenic shock. In patients presenting with acute, progressive myelopathy coupled with severe autonomic instability, it is imperative to consider ischemic injury in the differential diagnosis.

Abstract Objective We report a 11-month-old under immunized girl from the United States with ischemic stroke associated with inflammatory focal cerebral arteriopathy secondary to tuberculous meningitis. Methods Diagnosis was based upon the head CT, brain MRI, and magnetic resonance angiography (MRA) of the head and neck, CSF evaluation, TB blood and skin test, and gastric aspirate culture. Results Patient presented to the local emergency department (ED) for left arm and leg weakness. Laboratory work was significant for hyponatremia. Head CT demonstrated an area of attenuation in the right basal ganglia and caudate nucleus, and a focus of gray and white matter differentiation loss in the right frontal cortex. MRI brain showed a right middle cerebral artery stroke. CSF evaluation showed pleocytosis with hypoglycorrhachia and elevated protein. Further testing showed mediastinal and hilar lymphadenopathy and additional history included exposure to a grandparent with active tuberculosis. Discussion This case emphasizes the importance of childhood vaccinations and considering CSF evaluation, which is usually not considered as part of routine pediatric stroke work up. With increasing international travel and global immigration, clinicians even in the non-endemic countries should consider tuberculosis in their differential diagnosis.

Intro: Movement disorders following stroke are a rare but known phenomenon. Presentations includes chorea, dystonia, tremor, ballism, and parkinsonism. They can occur acutely or delayed; they can be transient or persistent. The basal ganglia are frequently involved. Presented here is a case of hemichorea following thrombectomy. Case: The patient is a 16-year-old male who presented to our ED with classic signs of left MCA stroke: acute right hemiparesis, facial droop, and aphasia. Imaging demonstrated thrombus at the left ICA terminus. He received TPA and was briefly transferred to an outside hospital for thrombectomy. He returned to our hospital the next day for ongoing management with a very different exam. His facial droop and aphasia were resolved, with only slight weakness in the right arm and leg. However, he had new involuntary movements on the right side, described as chorea. Seizure was ruled out with negative EEG. Repeat imaging showed left MCA territory infarct with some residual clot within the left MCA but improved flow. His hemichorea was thought to be the result of basal ganglia involvement of stroke. He was started on tetrabenazine for management. Discussion: Hemichorea following stroke is a rare finding, estimated at 1% based on literature review. Notably, these studies were in adults; prevalence among pediatric and adolescent stroke survivors could not be found. Imaging typically demonstrates basal ganglia involvement though other involved structures include the thalamus, subthalamic nuclei, and cortex. Chorea after ischemic stroke tends to present quickly, within hours. It is noteworthy that our patient initially presented with hemiparesis, but, following thrombectomy, had quick return of strength but acute hemichorea. Pharmacologic therapy options include antipsychotics, benzodiazepines, antiepileptics, and tetrabenazine. Improvement or resolution of chorea within 6 weeks is reported in most patients, though some will have persistent symptoms.

Introduction: Children with moyamoya and their parents experience significant stress around the time of diagnosis. There are not many studies that examine the extent of the symptoms including clinical concerns for anxiety and depression around time of diagnosis. Hypothesis: Children with moyamoya and their parents will have higher rates of anxiety and depression on standardized questionnaires than the general population. Methods: We enrolled parents of children with moyamoya as well as the child if child was 6 years of age or older prior to revascularization surgery. At time of enrollment parents and child filled out standardized questionnaires on symptom of anxiety and depression. Parents filled out Beck's Depression Inventory (BDI) and Beck's Anxiety Inventory (BAI). Children filled out the Behavioral Assessment System for Children 3rd edition (BASC-3). Results: A total of 22 children with moyamoya enrolled in our study, some children were less than 6 years old so we did not collect emotional outcomes on them. Children's age ranged from 13 months to 18 years old with 14 females (63%). In our cohort of children with moyamoya 12 children, 17 mothers, and 12 fathers filled out questionnaires. Four fathers (33%) and 4 mothers (24%) had clinical concern for depression. We did not have any mothers or fathers with clinical concern for anxiety. However, 4 children (33%) had clinical concern for anxiety and 3 children (25%) had clinical concern for depression. Conclusion: Compared to the general population children with moyamoya have higher rates of depression and anxiety while their parents have higher rates of depression. Further research is needed to determine if symptoms improve post-revascularization surgery.

**Abstract body:**

Pediatric stroke has a significant impact on children and families. Outcome measures are essential to guide clinical management and inform research priorities, yet these instruments are highly varied in scope and application. Because pediatric stroke care and research is evolving, there is a need for a current review of pediatric stroke outcome measures. The purpose of this study was to systematically review the current literature for pediatric outcome measures, describe the studies using pediatric outcome measures, and describe the outcome measure characteristics. From an initial search of 1625 articles with duplicates removed, 116 articles met inclusion criteria. In those 116 articles, 95 distinct outcome measures were identified. Our review noted the most used outcome measures focused on deficits of the child whereas there was a paucity of outcomes used that included patient and family perspectives, recovery in natural contexts (e.g., home, school, community), and inadequate representation executive function and quality of life. We also found a lack of reliable and valid outcomes for the pediatric hemorrhagic stroke population, and a limited number of outcomes that measure recovery over time. The findings in this systematic review support recommendations for future development and use of pediatric stroke outcome measures, particularly for pediatric hemorrhagic stroke, that better capture the impacts to child and family life and contextually meaningful aspects of recovery over time.
