pediatric venous thromboembolism

Hyoung Soo Choi, Chang Won Choi, Heon Min Kim, Hye Won Park
BACKGROUND: While venous thromboembolism (VTE) is uncommon, its incidence is increasing in children. We aimed to evaluate the incidence, risk factors, treatment, and outcome of pediatric VTE cases at a single tertiary hospital in Korea. METHODS: We retrospectively analyzed the records of consecutive pediatric VTE patients admitted to the Seoul National University Bundang Hospital between April 2003 and March 2016. RESULTS: Among 70,462 hospitalizations, 25 pediatric VTE cases were identified (3...

Complications following spine fusion for adolescent idiopathic scoliosis can be characterized as either intra-operative or post-operative. The most serious and feared complication is neurologic injury, both in the intra- and post-operative period. Other intra-operative complications include dural tears and ophthalmologic or peripheral nerve deficits, which may be related to positioning. Among the most common post-operative complications are surgical site infection, venous thromboembolism, gastrointestinal complications, and implant-related complications...

The VTE is mainly a disease of the older adult, though its incidence has increased significantly in the pediatric population over the past several years. This trend is likely due to enhanced awareness and recognition of VTE, as well as increased prevalence of thromboembolic associated risk factors, such as increases in the proportion of children with predisposing medical conditions. The evaluation and management of a child with VTE is similar to that of adults, however pediatric patients have their own distinct aspects of care, stemming from particularities of the hemostatic system, age-related risk factors and differences in response to anticoagulant and antithrombotic therapy...

BACKGROUND: Venous thromboembolism (VTE) is extremely rare but under recognized in the pediatric population. Although the literature on the use of ultrasound to detect VTEs in adults is plentiful, little has been documented on its use in the pediatric population. CASE REPORT: We present a case of a healthy 16-year-old female who presented to our emergency department with 3 months of dyspnea on exertion and one episode of near-syncope. Point-of-care cardiac ultrasound identified an inferior vena cava thrombosis...

Thromboembolism is being detected at increasing rates in pediatric tertiary care hospitals. The incidence of pediatric thrombophilia differs across countries, and is unknown in Japan. We sent a survey to 520 pediatric department heads and 629 specialists, requesting details on patients who developed symptomatic thromboembolism between 2006 and 2010. Of 280 eligible cases, congenital thrombophilia and other conditions were reported. Congenital thrombophilia (n = 54, 19.3 %) comprised defects in protein C (27), protein S (9), and antithrombin (7)...

Anticoagulation using intravenous bolus administration of unfractionated heparin (UFH) aims to prevent thromboembolic complications in children undergoing cardiac catheterization (CC). Optimal UFH dosage is needed to reduce bleeding complications. We analyzed the effect of bolus UFH on activated clotting time (ACT) in children undergoing CC focusing on age-dependent, anesthesia-related, or disease-related influencing factors. This retrospective single-center study of 183 pediatric patients receiving UFH during CC analyzed ACT measured at the end of CC...

OBJECTIVE: To evaluate the association between Cushing syndrome and hypercoagulability in children. STUDY DESIGN: A prospective, observational study was performed of 54 patients with Cushing syndrome, 15.1 ± 3.9 years, treated at the National Institutes of Health Clinical Center. Coagulation profiles were taken before and 6-12 months after surgery and compared with18 normocortisolemic children, 13.7 ± 3.6 years. RESULTS: At baseline, patients with Cushing syndrome had greater levels of the procoagulant factor VIII (FVIII) vs controls (145 IU/dL ± 84 vs 99 ± 47, P = ...

PURPOSE: Patients with long-gap esophageal atresia (LGEA) treated with the Foker process are at increased risk of venous thromboembolism (VTE). An institutional quality improvement program to decrease VTE risk factor exposure and utilize prophylactic anticoagulation was implemented. We aim to evaluate the efficacy and safety of a VTE risk-reduction program in patients with LGEA. METHODS: Implementation and evaluation of a VTE risk-reduction program in patients with LGEA from 2012 to 2015 was performed...

INTRODUCTION: Venous thrombotic events (VTE) are becoming more and more common in children, particularly in the hospital setting. To date, 1 in 200 children admitted to tertiary pediatric hospitals are now being recognized to develop VTE. Amongst those patients with an identified thrombotic occlusion, pediatric patients diagnosed with renal tumors have long been recognized, but their ideal management in the instances of vascular invasion remains controversial. AIM: We describe the clinical behavior of patients diagnosed with renal tumors and extra renal vascular involvement at The Hospital for Sick Children in Toronto, Canada...

Patients with cystic fibrosis (CF) are at increased risk of venous thromboembolism, especially in association with central venous catheter use. Coumarin drugs and low molecular weight heparin are frequently used for anti-coagulant therapy, but are more challenging to administer in CF patients. Dabigatran, an oral thrombin antagonist, is an alternative anti-coagulant medication, but its use in CF has not been reported. We describe our experience in successfully using dabigatran for long-term anti-coagulation therapy in two CF patients...

BACKGROUND: Pediatric oncology patients with tunneled central venous catheters (CVCs) are at increased risk to develop venous thromboembolic events (VTEs), but the true prevalence of (a)symptomatic VTE is unknown. Aim of this study was to evaluate the prevalence of (a)symptomatic VTE in pediatric oncology patients with tunneled CVCs. PROCEDURE: All patients were included in the Aristocaths study: a randomized controlled multicenter trial investigating the prophylactic effect of 70% ethanol locks on CVC-associated bloodstream infections (CABSIs) were eligible for this study...

Aim Localized intravascular coagulopathy (LIC) has been described in adults with venous malformation (VM) but rarely reported in children. This study aims to determine the prevalence of LIC in children with VM and associated risk factors. Methods Patients younger than 18 years with VM from 2010 to 2014 were reviewed. Diagnosis was confirmed by Doppler ultrasound and/or magnetic resonance imaging. Demographics data and VM characteristics including volume, site, extension, painful symptoms, and palpable phleboliths were studied...

OBJECTIVES: To investigate the clinical and epidemiologic characteristics of thromboembolism in Japanese children. METHODS: Clinical data of 77 patients with thromboembolism from a national tertiary pediatric care center were reviewed. RESULTS: Incidence of thromboembolism was calculated to be 15 per 10,000 hospital admissions. Infants younger than one year of age made up the largest age group (25 patients, including nine neonates younger than 30 d)...

OBJECTIVE: To determine the incidence, incidence trend, and mortality of venous thromboembolism (VTE) in a general pediatric population during an 11-year period. STUDY DESIGN: The administrative health care databases of the province of Québec, Canada were used to identify all children (ages 1-17 years inclusive) diagnosed with incident VTE between January 1, 1994 and December 31, 2004. The incidence rate and trend over the 11-year study period were then analyzed...

Pharmacological thromboprophylaxis (pTP) is the most effective intervention to prevent venous thromboembolism (VTE) in hospitalized adults. High-quality studies investigating the role of pTP in children are lacking. The aim of this study is to understand pediatric hematologists' current practices of pTP prescription and to explore their opinion about universal adoption of pTP for high-risk hospitalized children. An electronic survey was sent to members of Hemostasis and Thrombosis Research Society of North America...

INTRODUCTION: The risk of morbidity associated with venous thromboembolism (VTE) after pediatric orthopaedic surgery remains unclear despite increased use of thromboprophylaxis measures. METHODS: The American College of Surgeons National Surgical Quality Improvement Program, Pediatric database was queried for patients undergoing an orthopaedic surgical procedure between 2012 and 2013. Upper extremity and skin/subcutaneous surgeries were excluded. Associations between VTE and procedure, demographics, comorbidities, preoperative laboratory values, and 30-day postoperative outcomes were evaluated...
