Karakas C, Herman I, Kralik SF, Webber TA, Takacs DS, Bhar S, Pehlivan D. A Comprehensive Examination of Clinical Characteristics and Determinants of Long-Term Outcomes in Pediatric Cerebral Sinus Venous Thrombosis. Pediatr Neurol 2024; 155:76-83. [PMID: 38608552 DOI: 10.1016/j.pediatrneurol.2024.03.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 03/17/2024] [Accepted: 03/19/2024] [Indexed: 04/14/2024]
Abstract
BACKGROUND To analyze the clinical and neuroimaging features, risk factors, treatment choices, and long-term clinical outcomes in children with cerebral sinus venous thrombosis (CSVT). METHODS This is a retrospective cohort study of children diagnosed with CSVT between 2002 and 2018 at Texas Children's Hospital. RESULTS A total of 183 children (male: 62.3%) with CSVT were included. The average presenting age was 7.7 years (S.D.: 5.6). The mean follow-up duration was 33.7 months (S.D.: 38.6). The most common presenting clinical feature was headache (36.6%). Head and neck infections other than meningitis (36.6%) were the most common risk factors. Prevalent neurological examination findings included motor deficit (21.3%) and altered mental status (AMS, 20.2%). Neuroimaging features included hemorrhagic infarction (19.6%), ischemic infarction (8.2%), and intracranial hemorrhage without infarction (5.5%). The most common site of thrombosis was the superior sagittal sinus (37.2%), with 78.2% of patients demonstrating involvement of multiple sinuses. Treatment of choice was low-molecular-weight heparin in 69.4% of patients. Factors associated with worse clinical outcomes included head and neck infections, malignancy (other than hematologic), cardiac disease, and recent surgery; seizure and dehydration on initial presentation; motor abnormalities and AMS on initial examination; ischemic infarct only; and involvement of vein of Trolard on neuroimaging. Thrombus condition on repeat imaging, receiving any anticoagulant/antithrombotic treatment, treatment duration, or follow-up duration was not associated with severity of long-term outcome. CONCLUSIONS CSVT may lead to unfavorable long-term outcomes in a remarkable portion of pediatric patients. Thus, a high index of suspicion and early and appropriate management of pediatric CSVT is imperative.

Abstract
Cerebral venous thrombosis (CVT) is a rare cerebrovascular disorder characterized by the obstruction of venous channels in the brain. Genetic factors play a significant role in CVT development, and recent studies have identified gain-of-function mutations in coagulation factors, including factor IX (FIX). This case report focuses on a unique neonatal case of CVT, where an X-chromosome duplication involving the F9 gene resulted in increased FIX activity. The neonate presented with feeding difficulties, weight loss, nystagmus, and seizures. Imaging and laboratory tests confirmed a 554-kb X-chromosome duplication encompassing the F9 gene. This genetic abnormality likely contributed to the elevated FIX activity level and subsequent CVT development. Understanding the relationship between coagulation factor abnormalities and CVT risk expands our knowledge of thrombophilia's genetic basis and may aid in the development of targeted treatment strategies for CVT management.

Abstract
BACKGROUND Cerebrovascular disorders are an important cause of morbidity and mortality in children. The acute care of a child with an ischemic or hemorrhagic stroke or cerebral sinus venous thrombosis focuses on stabilizing the patient, determining the cause of the insult, and preventing secondary injury. Here, we review the use of both invasive and noninvasive neuromonitoring modalities in the care of pediatric patients with arterial ischemic stroke, nontraumatic intracranial hemorrhage, and cerebral sinus venous thrombosis. METHODS Narrative review of the literature on neuromonitoring in children with cerebrovascular disorders. RESULTS Neuroimaging, near-infrared spectroscopy, transcranial Doppler ultrasonography, continuous and quantitative electroencephalography, invasive intracranial pressure monitoring, and multimodal neuromonitoring may augment the acute care of children with cerebrovascular disorders. Neuromonitoring can play an essential role in the early identification of evolving injury in the aftermath of arterial ischemic stroke, intracranial hemorrhage, or sinus venous thrombosis, including recurrent infarction or infarct expansion, new or recurrent hemorrhage, vasospasm and delayed cerebral ischemia, status epilepticus, and intracranial hypertension, among others, and this, is turn, can facilitate real-time adjustments to treatment plans. CONCLUSIONS Our understanding of pediatric cerebrovascular disorders has increased dramatically over the past several years, in part due to advances in the neuromonitoring modalities that allow us to better understand these conditions. We are now poised, as a field, to take advantage of advances in neuromonitoring capabilities to determine how best to manage and treat acute cerebrovascular disorders in children.

Abstract
Cerebral venous thrombosis in pediatric patient has a varied etiology. The authors present the case of a teenager who, since the debut of SARS-CoV-2 infection, has accused intermittent right side hemicrania, which has become persistent in association with nausea and vomiting since the 5th day of quarantine. She was hospitalized in the 9th day since the debut. Neuroimaging revealed extended venous cerebral thrombosis affecting the right sigmoid sinus, the transverse sinus bilaterally, the confluence of the transverse sinuses and the right internal jugular vein. The evolution was favorable under anticoagulant and symptomatic treatment. Laboratory tests excluded other etiological causes for the cerebral venous thrombosis, thus the authors consider that cerebral thrombosis is a possible complication of SARS-CoV-2 infection in teenagers.

Abstract
Objectives The study objective was to calculate the birth prevalence of perinatal stroke and examine risk factors in term infants. Some risk factors are present in healthy infants, making it difficult to determine at-risk infants. Study Design Prospective population-based perinatal stroke data were compared to the Australian general population data using chi-squared and Fisher's exact tests and multivariable logistic regression analysis. Results Sixty perinatal stroke cases were reported between 2017 and 2019. Estimated stroke prevalence was 9.6/100,000 live births/year including 5.8 for neonatal arterial ischemic stroke and 2.9 for neonatal hemorrhagic stroke. Eighty seven percent had multiple risk factors. Significant risk factors were cesarean section (p = 0.04), 5-min Apgar score <7 (p < 0.01), neonatal resuscitation (p < 0.01) and nulliparity (p < 0.01). Conclusions Statistically significant independent risk factors do not fully explain the cause of perinatal stroke, because they are not a direct causal pathway to stroke. These data now require validation in a case-control study.

Abstract
Cerebral sinovenous thrombosis (CSVT) is a rare, yet potentially devastating disorder, associated with acute complications and long-term neurologic sequelae. Consensus-based international pediatric CSVT treatment guidelines emphasize early clinical-radiologic recognition and prompt consideration for anticoagulation therapy. However, lack of clinical trials has precluded evidence-based patient selection, anticoagulant choice, optimal monitoring parameters and treatment duration. Consequently, uncertainties and controversies persist regarding anticoagulation practices in pediatric CSVT. This review focuses on commonly encountered issues that continue to pose questions and raise debates regarding anticoagulation therapy among pediatric neurologists and hematologists.

Abstract
BACKGROUND Pediatric cavernous sinus thrombosis (CST) is a rare condition with limited data regarding its clinical characteristics and long-term outcomes. The objective of this study was to describe the clinical and radiologic features, diagnostic evaluation, management, and long-term prognosis and to identify clinical variables associated with long-term outcomes in pediatric CST. METHODS A retrospective chart review of patients younger than 18 years diagnosed with a CST between 2004 and 2018 at a single center was conducted. RESULTS We identified 16 (M:F = 10:6) children with CST with a mean age of 7.6 years (10 days to 15 years) and average follow-up duration of 29 months (3 weeks to 144 months). The most common symptom and examination finding at presentation was eyelid swelling (n = 8). Six patients had bilateral CST. The most common etiologies were sinusitis (n = 5) and orbital cellulitis (n = 5). Treatments included antibiotics (n = 14), anticoagulation (n = 11), and surgery (n = 5). Only one patient died due to intracranial complications. Twelve patients had a normal examination at follow-up. None of the clinical variables including age (P = 0.14), gender (P = 0.09), use of antibiotics (P = 1.00) or anticoagulation (P = 1.00), surgery (P = 0.28), parenchymal abnormalities (P = 0.30), additional cerebral venous thrombosis (P = 0.28), and early versus late commencing of anticoagulation (P = 1.00) were significant when comparing patients with full/partial resolution versus those with no resolution of thrombosis on follow-up neuroimaging. CONCLUSIONS Our study is one of the largest cohorts with the longest follow-up data for the pediatric CST. Most of our patients had favorable outcomes at follow-up. We found no statistical difference between clinical variables when comparing patients with full/partial resolution versus those with no resolution of thrombosis on follow-up neuroimaging.

Abstract
We present a rare case of cerebral venous sinus thrombosis in a COVID-19-positive, 2-month-old infant, to this day the youngest described patient with this rare combination of findings. He was hospitalized with focal seizures. The first brain imaging showed subdural hematoma and focal ischemic changes. The subdural hematoma was successfully evacuated. The control imaging, done due to lethargy, showed an extensive cerebral venous sinus thrombosis. The thrombosis was managed with low molecular weight heparin leading to clinical and radiological improvement. With this case report, we would like to add to the information pool of COVID-19 neurological manifestations in children, particularly those younger than 1 year.

Abstract
BACKGROUND Paediatric otogenic cerebral venous sinus thrombosis is a rare, heterogeneous and life-threatening condition, with possible otological, neurological and ophthalmological sequelae. Its course and outcomes can be widely variable. The publications available often consider individual aspects of paediatric otogenic cerebral venous sinus thrombosis management. The condition itself and the nature of the currently available guidance can lead to uncertainties when holistically managing patients with paediatric otogenic cerebral venous sinus thrombosis. OBJECTIVES Clear recommendations for the comprehensive assessment and management of paediatric otogenic cerebral venous sinus thrombosis are presented, along with the literature review upon which they are based. Its clinical and radiological assessment are discussed. CONCLUSION A multidisciplinary approach to assessment and management is recommended, inclusive of infectious diseases, ENT surgery, neurology, ophthalmology and haematology. On balance, anticoagulation is recommended for three months. Follow-up imaging is not recommended in the absence of clinical concern. Follow up by ENT surgery, neurology and ophthalmology departments is recommended.

Abstract
INTRODUCTION Pediatric cerebral sinus venous thrombosis (CSVT) is a rare entity. Risk factors differ from the adults, and treatment is not consensual. With this work, we aimed to characterize a pediatric cohort from two Portuguese tertiary centers. METHODS All patients under 18 years old with confirmed CSVT admitted between 2006 and 2019 were retrospectively included. Demographics, clinical presentation, workup, and follow-up were evaluated. RESULTS Fifty-three patients were included, 29 were male (54.7%). Median age was 5 years (IQR 11.08, range 0-17 years old). Headache, seizures and impairment of consciousness were the most frequent manifestations. A risk factor was identified in 90.6% (n = 48), mostly infections (43.8%; n = 21). CNS complications were comprised of hemorrhage, venous infarction, hydrocephalus and edema. Treatment included anticoagulation in 36 patients (67.9%), and there were no recurrences on follow-up. Prognosis was favorable, with most patients presenting no or only slight disability comparing to same age and sex children, on the follow-up. DISCUSSION In this cohort, impairment of consciousness was the most frequent clinical presentation and infections were the most frequent risk factors. The outcome was mainly favorable, with most patients presenting none or mild disability and without recurrences on follow-up. Studies are needed to define the criteria for anticoagulation and its recommended duration in children.

Abstract
PURPOSE Cerebral venous thrombosis (CVT) is a rare disease in children, characterized by partial or total occlusion of blood flow in the cerebral venous system. The aim of this study is to describe clinical presentation, neuroimaging features, therapeutic management, and outcome of children with CVT. METHODS We retrospectively analyzed the data, including clinical manifestations, laboratory data, neurological findings, and treatment of children with radiologically confirmed CVT, admitted between January 2010 and March 2020 to our hospital. Cases of CVT complicating brain surgery were excluded. RESULTS We enrolled 24 children with CVT. Infection was the main etiology (58.3%), followed by trauma in 16.7% of cases. In the remaining 25% of cases, the cause was identified only in one patient presenting a thrombophilic factor. The most frequent site of thrombosis was the superficial venous system (86.8%), with multiple localizations disclosed in 79% of patients. All children received anticoagulant therapy with low molecular weight heparin (LMWH). One patient died for systemic complications of an underlying disease. No patient developed hemorrhagic events during the therapy, lasting from 35 to 360 days (mean 86 days). In all but one surviving patients (22 out of 24), recanalization of the sinus was observed at AngioMRI performed during follow-up. No neurological complications of CVT were recorded (mean follow-up: 1.5 year). CONCLUSIONS CVT may present with subtle and unspecific clinical manifestations in children. High level of suspicion should be kept in trauma and sinusitis. Anticoagulation treatment is safe and effective and should be promptly started to improve outcome.

Abstract
Aim: The objective of the study was to systematically bring out the clinical presentations, neuro-imaging features, treatment given, and long-term outcomes of children with cerebral venous sinus thrombosis (CVST). Materials and Methods: Data were obtained by retrospective analysis of electronic records spanning 13 years, of children (<18 years) with a confirmed diagnosis of CVST based on magnetic resonance imaging of the brain and managed at a tertiary care children’s hospital in the UK. Results: Seventeen patients with pediatric CVST were identified over a 13-year study period, highlighting the uncommon prevalence of this entity. This study comprised 10 males and seven females. The age range at presentation was between 2 days and 17 years with a median age of 5.5 years. Headache was the commonest presenting symptom in 10 of 17 children and focal neurological signs were seen in 11 of 17 patients. Among risk factors, six patients had an antecedent infection of the ear/mastoid, three children had acute leukemia, and two patients had central venous catheters. Para-infectious CVST (seven of 17 patients) responded well to appropriate antibiotic therapy. Thrombophilia screens were available in 10 of 17 patients with noninfectious CVST and returned abnormal in four patients (two with Factor V Leiden mutations and one each with deficiency of protein C and anti-thrombin III). Anticoagulants were used in only six of 17 cases and were generally well tolerated. Follow-up data revealed, 11 of 17 patients had a complete recovery and four of 17 patients had residual neurological deficits. Two children died in the entire cohort. Conclusion: Pediatric CVST is uncommon and has a different spectrum from adults, with unique clinical triggers and thrombophilic states. Management varies significantly among clinicians, due to the paucity of trial evidence and also due to the heterogeneity of this condition in children.

Abstract
La thrombophlébite cérébrale est considérée comme une pathologie rare mais grave dont la fréquence sous-estimée est de plus en plus reconnu chez les enfants et contrairement aux adultes la prise en charge reste controversée. Nous rapportons le cas d’un enfant de 12 ans ayant été victime d’une morsure par un ami au niveau du cuir chevelu de la région fronto-temporale de la tête, évoluant par l’apparition d’une tuméfaction évoquant une cellulite fronto-temporo pariétale compliquée d’une thrombophlébite cérébrale, diagnostiquée sur la présentation clinique et l’imagerie. Notre patient était admis dans notre structure dans un tableau de trouble de conscience, ainsi le recours aux anticoagulants et au traitement étiologique a permis une bonne évolution clinique.

Abstract
La TVC est rare en général et particulièrement chez l’enfant. La survenue d’une HSA dans ce contexte est une situation très peu fréquente et seuls quelques cas sont rapportés dans la littérature. Sa symptomatologie est variable et souvent trompeuse. Non traitée ou en cas de traitement tardif l’issue peut être fatale ou conduire à des séquelles potentiellement graves. Nous rapportons l’observation d’un nourrisson de 22 mois reçu pour des convulsions avec coma stade II, syndrome d’hypertension intracrânienne et syndrome infectieux. Une septicémie à Pseudomonas spp a était retrouvée à la biologie et le scanner cérébral a permis de poser le diagnostic. Le traitement a été basé sur l’antibiothérapie mais surtout l’anticoagulation. Une nette amélioration clinique a été ainsi notée et le scanner cérébral de contrôle montrait une disparition de la thrombose avec images hémorragiques séquellaires droites. La TVC est une pathologie grave d’origine généralement infectieuse. Le traitement anticoagulant est aujourd’hui sujet à controverse notamment en cas d’hémorragie associée, mais l’expérience clinique serait en faveur de l’efficacité et de l’innocuité de ce traitement.

Abstract
OBJECTIVE Pediatric cerebral venous sinus thrombosis has been previously described in the setting of blunt head trauma; however, the population demographics, risk factors for thrombosis, and the risks and benefits of detection and treatment in this patient population are poorly defined. Furthermore, few reports differentiate between different forms of sinus pathology. A series of pediatric patients with skull fractures who underwent venous imaging and were diagnosed with intrinsic cerebral venous sinus thrombosis or extrinsic sinus compression is presented. METHODS The medical records of patients at 2 pediatric trauma centers were retrospectively reviewed. Patients who were evaluated for blunt head trauma from January 2003 to December 2013, diagnosed with a skull fracture, and underwent venous imaging were included. RESULTS Of 2224 pediatric patients with skull fractures following blunt trauma, 41 patients (2%) underwent venous imaging. Of these, 8 patients (20%) had intrinsic sinus thrombosis and 14 patients (34%) displayed extrinsic compression of a venous sinus. Three patients with intrinsic sinus thrombosis developed venous infarcts, and 2 of these patients were treated with anticoagulation. One patient with extrinsic sinus compression by a depressed skull fracture underwent surgical elevation of the fracture. All patients with sinus pathology were discharged to home or inpatient rehabilitation. Among patients who underwent follow-up imaging, the sinus pathology had resolved by 6 months postinjury in 80% of patients with intrinsic thrombosis as well as 80% of patients with extrinsic compression. All patients with intrinsic thrombosis or extrinsic compression had a Glasgow Outcome Scale score of 4 or 5 at their last follow-up. CONCLUSIONS In this series of pediatric trauma patients who underwent venous imaging for suspected thrombosis, the yield of detecting intrinsic thrombosis and/or extrinsic compression of a venous sinus was high. However, few patients developed venous hypertension or infarction and were subsequently treated with anticoagulation or surgical decompression of the sinus. Most had spontaneous resolution and good neurological outcomes without treatment. Therefore, in the setting of pediatric skull fractures after blunt injury, venous imaging is recommended when venous hypertension or infarction is suspected and anticoagulation is being considered. However, there is little indication for pervasive venous imaging after pediatric skull fractures, especially in light of the potential risks of CT venography or MR venography in the pediatric population and the unclear benefits of anticoagulation.

Abstract
The incidence of diagnosed venous thromboembolism (VTE) has been increasing concurrent with advances in technology and medical care that enhance our ability to treat pediatric patients with critical illness or complex multiorgan system dysfunction. Although the overall incidence of VTE is estimated at 0.07-0.49 per 10,000 children, higher rates are observed in specific populations including hospitalized children, those with central venous catheters (CVCs) or patients convalescing from a major surgery. While the absolute number of pediatric VTE events may seem trivial compared to adults, the increasing incidence, associated with increased mortality and morbidity, the availability of novel therapies, and the impact on the cost of care have made investigation of VTE risk factors and prevention strategies a high priority. Many putative risk factors for pediatric VTE have been reported, primarily from single-institution, retrospective studies which lack appropriate methods for verifying independent risk factors. In addition, some risk factors have inconsistent definitions, which vex meta-analyses. CVCs are the most prevalent risk factors but have not consistently been assigned the highest level of risk as defined by odds ratios from retrospective, case-control studies. Few risk-assessment models for hospital-acquired pediatric VTE have been published. Some models focus exclusively on hospitalized pediatric patients, while others target specific populations such as patients with cancer or severe trauma. Multicenter, prospective studies are needed to identify and confirm risk factors in order to create a pediatric risk-assessment tool and optimize preventive measures and reduce unintended harm.

Abstract
Cerebral venous sinus thrombosis (CVST) following a closed head injury in pediatric patients is a rare condition, and an early spontaneous recanalization of this condition is extremely rare. A 10-year-old boy was admitted with a mild, intermittent headache and nausea five days after a bicycle accident. The brain computed tomography showed an epidural hematoma at the right occipital area with pneumocephalus due to a fracture of the occipital skull bone. The brain magnetic resonance imaging and the magnetic resonance venography demonstrated a flow signal loss from the right sigmoid sinus to the right jugular vein. The diagnosis was sigmoid sinus thrombosis, so close observations were selected as a treatment for the patient because of his gradually improving symptoms; however, he complained of vomiting 14 days the after conservative treatment. The patient was readmitted for a further examination of his symptoms. The laboratory and the gastroenterological examinations were normal. Due to concern regarding the worsening of the sigmoid sinus thrombosis, the brain magnetic resonance venography was rechecked and it revealed the recanalization of the venous flow in the sigmoid sinus and in the jugular vein.

Abstract
OBJECTIVES We evaluated clinical features, treatment practices and early outcome in a multicentre cohort of children with cerebral sinovenous thrombosis (CSVT). METHODS Children with CSVT from 10 countries were enrolled from January 2003 to July 2007 in the International Paediatric Stroke Study. We analysed clinical symptoms, underlying conditions, antithrombotic treatment and neurological outcome at hospital discharge in 170 children. RESULTS Of 170 children enrolled, 60% were male; median age 7.2 years (IQR 2.9-12.4). Headache, altered consciousness, focal deficits and seizures were common presenting clinical features. Infarction affected 37% and intracranial haemorrhage 31%. Risk factors included chronic disease in 50%; acute systemic illness or head/neck disorders 41%; prothrombotic state 20% and other haematological abnormality 19%. Discharge neurological status was normal in 48%, abnormal in 43% and unknown in 5%. Antithrombotic therapy was common, most often low molecular weight heparin was common, with significant regional variation in treatment practices. Mortality was low (4%) and was associated with no anticoagulation but not underlying chronic disease, anatomic extent of thrombosis or intracranial haemorrhage. Abnormal neurological status at discharge or death was associated with decreased level of consciousness at presentation and the presence of an identified prothrombotic state. CONCLUSIONS Our study extends the observations of previously published smaller studies in children with CSVT that this is a morbid disease with diverse underlying causes and risk factors. Divergent treatment practices among highly specialised centres as well as limited data on treatment efficacy and safety suggest that further study of this condition is warranted.

Abstract
BACKGROUND Head injury is a risk factor for cerebral sinovenous thrombosis (CSVT) in children. Literature concerning head injury-associated CSVT (HIA-CSVT) is scarce. Data supporting safety and efficacy of anticoagulant therapy (ACT) in childhood CSVT is emerging. However, intracranial hemorrhage (ICH) occurs frequently in children with HIA-CSVT at diagnosis making initiation of ACT controversial due to the fear of worsening of ICH. PROCEDURE We conducted a retrospective descriptive review of a consecutive cohort of children with HIA-CSVT from 1998 to 2012. RESULTS Twenty patients (14 males, mean age 7 years) with HIA-CSVT were identified. Most (19/20 [95%]) had significant ICH at diagnosis. None received ACT at diagnosis. Fourteen (70%) were later (median 7 days post-trauma, range 2-48 days) treated with ACT due to CSVT persistence (nine) and propagation (five), despite ICH in 13. None of the treated patients, including the 13 with pre-existing ICH, had significant worsening of hemorrhage. Three (21%) treated patients had minor asymptomatic extension of their hemorrhage and further ACT was withheld. No patient died while on ACT. No patient experienced CSVT propagation on ACT. Clinical outcomes were normal (no neurologic deficits) in 5/20(25%), mild neurological deficits in 10/20(50%), and moderate-severe neurological deficits in 5/20(25%). Small sample size did not permit assessment of the effect of ACT on outcome. CONCLUSIONS Anticoagulant therapy is safe in selected children with HIA-CSVT. ICH is not an absolute contraindication to ACT in children with HIA-CSVT.

Abstract
Acute lymphoblastic leukemia (ALL) is the most common type of cancer diagnosed in children, and has been reported as the most common malignancy associated with thromboembolism in the pediatric age group. Treatment with Escherichia coli asparaginase, concomitant steroids, presence of central venous lines, and thrombophilic abnormalities are established risk factors for thromboembolism. The incidence varies with age, co-morbidities and chemotherapy regimens but the risk is highest during the induction and intensification phases. Treatment is necessary in majority of children to prevent serious sequelae. Mortality from thromboembolic events in any location is 2 to 4 % and the risk of recurrence is 7 to 10 %, further enhanced in the setting of malignancy. Randomized trials of venous thromboembolism (VTE) management in pediatric patients with ALL are lacking due to the low overall incidence, resulting in considerable variation in practice. The objective of this article is to review current knowledge on the treatment and prevention of thrombosis associated with pediatric ALL.

Abstract
Cerebral sinodural thrombosis (CSDT) is a rare complication of minor head trauma in children. Despite recommendations, anticoagulation is frequently withheld. We aimed to evaluate the etiology, clinical presentation, risk factors, diagnosis, treatment, and outcome of pediatric CSDT following minor head trauma, and specifically to evaluate factors associated with anticoagulation use following minor head trauma in pediatric patients with CSDT. A literature search from 1990 to 2012 identified manuscripts discussing epidemiology, risk factors, clinical presentation, management, and outcome in pediatric patients with CSDT subsequent to minor head trauma. One pediatric patient diagnosed with CSDT following minor head trauma in our institution was also included in the study. There were 18 pediatric patients with CSDT following minor trauma, including the current patient. Mean patient age was 7.8years (range 23months-15years). There was a strong female predominance (2.4:1). Vomiting and headache were the most common symptoms. Five patients had pre-existing risk factors (gastroenteritis, protein S deficiency, estroprogestenic medication, elevated antiphospholipid antibodies, malnutrition). Anticoagulation was administered to six patients with additional risk factors, severe symptoms, or deterioration. There was no mortality, 12 patients recovered fully, and four patients improved with residual symptoms. One patient required lumboperitoneal shunt placement. Pediatric CSDT is a rare complication of minor head trauma, with variable presentation. Anticoagulation has generally been reserved for patients suffering from severe symptoms, for those who deteriorate neurologically during observation, and for those who suffer from a concomitant prothrombotic disorder.

Abstract
Iron deficiency anemia is a common pediatric problem affecting up to 25% children worldwide. It has been linked with cerebral venous sinus thrombosis in the literature. We describe a 9-month-old child who had severe iron deficiency anemia and developed acute venous sinus thrombosis associated with minor infection. Treatment with anticoagulation was partially successful with persistent thrombosis after 3 months. We reviewed the current literature highlighting the association of anemia as a risk factor for development of stroke in children.

Abstract
Anticoagulation of cerebral sinovenous thrombosis (CSVT) is recommended in adults and has been also approved in the paediatric setting. Some controversies remain however between the existing paediatric professional consensus, notably about its use in children with intra-cranial haemorrhage and in neonates. The publication of further original studies prompted the French Society for Paediatric Neurology (SFNP) in association with a panel of EPNS experts, to update the level of evidence and the knowledge in this domain. A bibliographic analysis revealed that anticoagulants are widely used in paediatrics. Anticoagulation is well tolerated by children (Class I, level of evidence B) and also probably by neonates (Class IIa, level of evidence B). During the acute phase, anticoagulation is probably effective in reducing the risk of death and sequelae in children (Class IIa, level of evidence B). It is not yet possible to draw any conclusions regarding neonates (Class IIb). Anticoagulation is also effective in reducing the risk of recurrence (Class I, level of evidence B). This risk is dependent on several individual factors such as the age of the child, the cause of the thrombosis, the persistence or the recurrence of thrombogenic factors, and the speed of sinus recanalisation. The duration of anticoagulation needs therefore to be individually tailored (Class I, level of evidence B). These observations have led to the following recommendations: -In the absence of any contraindication, it is reasonable to initiate anticoagulation during the acute phase of CSVT in children. Prolonged treatment over 3-6 months is justified according to individual factors. -In the absence of any contraindication, anticoagulation may be considered individually during the acute phase of CSVT in neonates for a duration of 6-12 weeks.

Abstract
BACKGROUND Neonates and children differ from adults in physiology, pharmacologic responses to drugs, epidemiology, and long-term consequences of thrombosis. This guideline addresses optimal strategies for the management of thrombosis in neonates and children. METHODS The methods of this guideline follow those described in the Methodology for the Development of Antithrombotic Therapy and Prevention of Thrombosis Guidelines: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines. RESULTS We suggest that where possible, pediatric hematologists with experience in thromboembolism manage pediatric patients with thromboembolism (Grade 2C). When this is not possible, we suggest a combination of a neonatologist/pediatrician and adult hematologist supported by consultation with an experienced pediatric hematologist (Grade 2C). We suggest that therapeutic unfractionated heparin in children is titrated to achieve a target anti-Xa range of 0.35 to 0.7 units/mL or an activated partial thromboplastin time range that correlates to this anti-Xa range or to a protamine titration range of 0.2 to 0.4 units/mL (Grade 2C). For neonates and children receiving either daily or bid therapeutic low-molecular-weight heparin, we suggest that the drug be monitored to a target range of 0.5 to 1.0 units/mL in a sample taken 4 to 6 h after subcutaneous injection or, alternatively, 0.5 to 0.8 units/mL in a sample taken 2 to 6 h after subcutaneous injection (Grade 2C). CONCLUSIONS The evidence supporting most recommendations for antithrombotic therapy in neonates and children remains weak. Studies addressing appropriate drug target ranges and monitoring requirements are urgently required in addition to site- and clinical situation-specific thrombosis management strategies.

Abstract
Neonatal stroke is a diverse clinical entity. Terminology and aetiology described in the literature are very varied. While numerous risk factors are cited, only few case-control studies have investigated them in a systematic fashion. This equipoise extends to the investigational and management profile of perinatal stroke too. Controversy persists about the suitability of detailed haematological thrombophilia workup in the neonatal period. This case-based review details the variable clinical presentation in term and preterm neonates, discusses the current literature, ascertains the respective roles of various imaging modalities, explores relevant new neuroprotective interventions and proposes a systematic approach to clinical and neuroimaging workup. Long-term follow-up is important as many infants suffer neuro-disability, which might need early intervention strategies.

Abstract
INTRODUCTION Pediatric stroke, while increasingly recognized among practitioners as a clinically significant, albeit infrequent entity, remains challenging from the viewpoint of clinicians and researchers. DISCUSSION Advances in neuroimaging have revealed a higher prevalence of pediatric stroke while also provided a safer method for evaluating the child's nervous system and vasculature. An understanding of pathogenic mechanisms for pediatric stroke requires a division of ages (perinatal and childhood) and a separation of mechanism (ischemic and hemorrhagic). This article presents a review of the current literature with the recommended divisions of age and mechanism. CONCLUSION Guidelines for treatment, though limited, are also discussed.

Abstract
Cutaneous scalp hemangiomas may herald the presence of occult intracranial hemangiomas. A previously healthy 4-month-old girl presented with a bleeding scalp hemangioma, a bulging fontanel, and anemia. Magnetic resonance imaging (MRI) of the brain revealed hydrocephalus along with multiple intracranial hemangiomas. These lesions compressed the jugular foramina, resulting in venous sinus thrombosis involving the right transverse sinus, the left sigmoid sinus, and the torcular herophili. The patient had no family history of phakomatoses or other genetic abnormalities. A thrombophilia work-up result was unremarkable. The patient was treated with prednisolone (10 mg twice daily) and low molecular weight heparin (1 mg/kg/dose) twice daily. This treatment decreased the size of her cutaneous and intracranial hemangiomas and led to the resolution of her venous sinus thromboses and hydrocephalus. Innocuous scalp hemangioma in an infant may herald more concerning intracranial pathology, which can be treated effectively if diagnosed with appropriate imaging studies.

Abstract
BACKGROUND The purpose of this statement is to provide an overview of cerebral venous sinus thrombosis and to provide recommendations for its diagnosis, management, and treatment. The intended audience is physicians and other healthcare providers who are responsible for the diagnosis and management of patients with cerebral venous sinus thrombosis. METHODS AND RESULTS Members of the panel were appointed by the American Heart Association Stroke Council's Scientific Statement Oversight Committee and represent different areas of expertise. The panel reviewed the relevant literature with an emphasis on reports published since 1966 and used the American Heart Association levels-of-evidence grading algorithm to rate the evidence and to make recommendations. After approval of the statement by the panel, it underwent peer review and approval by the American Heart Association Science Advisory and Coordinating Committee. CONCLUSIONS Evidence-based recommendations are provided for the diagnosis, management, and prevention of recurrence of cerebral venous thrombosis. Recommendations on the evaluation and management of cerebral venous thrombosis during pregnancy and in the pediatric population are provided. Considerations for the management of clinical complications (seizures, hydrocephalus, intracranial hypertension, and neurological deterioration) are also summarized. An algorithm for diagnosis and management of patients with cerebral venous sinus thrombosis is described.

Abstract
Cerebral venous sinus (sinovenous) thrombosis (CSVT) in childhood is a rare, but underrecognized, disorder, typically of multifactorial etiology, with neurologic sequelae apparent in up to 40% of survivors and mortality approaching 10%. There is an expanding spectrum of perinatal brain injury associated with neonatal CSVT. Although there is considerable overlap in risk factors for CSVT in neonates and older infants and children, specific differences exist between the groups. Clinical symptoms are frequently nonspecific, which may obscure the diagnosis and delay treatment. While morbidity and mortality are significant, CSVT recurs less commonly than arterial ischemic stroke in children. Appropriate management may reduce the risk of recurrence and improve outcome, however there are no randomized controlled trials to support the use of anticoagulation in children. Although commonly employed in many centers, this practice remains controversial, highlighting the continued need for high-quality studies. This article reviews the literature pertaining to pediatric venous sinus thrombosis.

Abstract
A 12-year-old boy who presented with headache and papilledema was diagnosed with cerebral sinus venous thrombosis and promyelocytic leukemia. Cerebral sinus venous thrombosis is an uncommon manifestation of acute promyelocytic leukemia, and acute promyelocytic leukemia is an unusual etiology for cerebral sinus venous thrombosis. This case highlights the importance of a complete evaluation for risk factors in a child presenting with cerebral sinus venous thrombosis. Anticoagulation was initiated for treatment of cerebral sinus venous thrombosis, and new asymptomatic hemorrhage was identified in the cerebellum 1 day later. Anticoagulation was discontinued for 5 days and then reinitiated in the intensive care unit without hemorrhage expansion or other complications. We review the literature regarding anticoagulation in children with cerebral sinus venous thrombosis and issues specific to acute promyelocytic leukemia. This case suggests that in a controlled setting, anticoagulation may be safe in selected patients with cerebellar hemorrhage.

Abstract
This study presents a large multicenter cohort of children with cerebral venous thrombosis from 5 centers in the United States and analyzes their clinical findings and risk factors. Seventy patients were included in the study (25 neonates, 35%). The age ranged from 6 days to 12 years. Thirty-eight (55%) were younger than 6 months of age, and 28 (40%) were male. Presenting features included seizures (59%), coma (30%), headache (18%), and motor weakness (21%). Common neurological findings included decreased level of consciousness (50%), papilledema (18%), cranial nerve palsy (33%), hemiparesis (29%), and hypotonia (22%). Predisposing factors were identified in 63 (90%) patients. These included infection (40%), perinatal complications (25%), hypercoagulable/hematological diseases (13%), and various other conditions (10%). Hemorrhagic infarcts occurred in 40% of the patients and hydrocephalus in 10%. Transverse sinus thrombosis was more common (73%) than sagittal sinus thrombosis (35%). Three children underwent thrombolysis, 15 patients received anticoagulation, and 49 (70%) were treated with antibiotics and hydration. Nine (13%) patients (6 of them neonates) died. Twenty-nine patients (41%) were normal, whereas 32 patients (46%) had a neurological deficit at discharge. Seizures and coma at presentation were poor prognostic indicators. In conclusion, cerebral venous thrombosis predominantly affects children younger than age 6 months. Mortality is high (25%) in neonatal cerebral venous thrombosis. Only 18 (25%) patients were treated with anticoagulation or thrombolysis.

Abstract
Cerebral sinovenous thrombosis (CSVT) is a rare but increasingly recognized disease process in children. In the pediatric population, the etiologies of CSVT are multiple and the outcomes are variable. The current therapies for CSVT include anticoagulation, thrombolysis, hydration, surgery, and supportive care. Adult studies, pediatric case studies, and expert opinion form the basis for these treatment strategies. International cooperative efforts are currently being undertaken to collect data on pediatric stroke patients, including CSVT. These multicenter collaborations are needed to increase our understanding of the incidence, risk factors, treatment modalities, and outcomes of CSVT in pediatric populations.

Abstract
Childhood ischaemic stroke, incorporating arterial ischaemic stroke and cerebral sinus venous thrombosis, is associated with significant morbidity and mortality in children. The majority of cases in children present with well-recognised risk factors. The appreciation of the role prothrombotic abnormalities have in disease states is developing rapidly. Prothrombotic abnormalities are abnormalities of the coagulation system, fibrinolytic system, endothelial cells or platelets that lead to a reduced threshold for pathological thrombus formation. Our understanding of the role of prothrombotic abnormalities in childhood ischaemic stroke is increasing and has a direct bearing on the development of effective management and prevention strategies. We provide a brief background of prothrombotic abnormalities and review the available literature on prothrombotic markers in childhood ischaemic stroke. Overall, prothrombotic abnormalities have been identified in 20-50% of children presenting with AIS and 33-99% of children with cerebral sinus venous thrombosis. There appear to be a number of associations emerging including an increased frequency of factor V Leiden mutation, elevated lipoprotein (a), protein C deficiency and antiphospholipid antibodies in children presenting with arterial ischaemic stroke. The pathogenic role of prothrombotic abnormalities as predisposing to initial and recurrent childhood ischaemic stroke is becoming increasingly evident. The impact on treatment, however, will only be clarified with carefully designed, multi-institutional prospective studies.
