Background: The term venous thromboembolism (VTE) includes deep venous thrombosis of the extremity and pulmonary embolism, a potentially fatal clinical entity. Although the prevalence of VTE may be lower in children compared with adults, recent reports suggest a possible rise in this diagnosis among pediatric patients, especially in association with certain risk factors. We assessed the clinical experience and practice of members of the Pediatric Orthopaedic Society of North America (POSNA) related to VTE among their pediatric patients.
Methods: A 36-question online survey was sent to all 636 active POSNA members. The proportion of surgeons who had encountered at least 1 child with VTE and the respondents' practice of using thromboprophylaxis in children (<18 y old) was assessed. The relationship of responders' experience with VTE among pediatric patients with various practice characteristics was evaluated.
Results: The response rate was 56% (354/636). More than half (55%) [95% confidence interval (CI), 50%-60%] of the respondents could recall at least 1 (median, 2 cases/member) pediatric patient with deep venous thrombosis and 29% (95% CI, 24%-34%) could recall ≥1 child with pulmonary embolism. Approximately one quarter (23%) (95% CI, 18%-27%) of all respondents reported never using mechanical prophylaxis and almost one half (45%) (95% CI, 40%-50%) of respondents reported never using pharmacologic prophylaxis against VTE in children. Only 16% (95% CI, 12%-20%) of the respondents had a thromboprophylaxis protocol for pediatric patients. Respondent characteristics such as being in clinical practice <5 years (P=0.01) and having a surgical volume of <100 cases/y (P=0.03) were associated with a lower likelihood of encountering a pediatric patient with VTE.
Conclusions: More than half of responding active POSNA members reported having come across at least 1 case of VTE among pediatric patients during their practice. The routine use of VTE prophylaxis for children is uncommon among pediatric orthopaedists. Further studies aimed at determining the prevalence of VTE and developing specific guidelines for prophylaxis among pediatric patients seeking orthopaedic care are warranted.

Non-bacterial thrombotic endocarditis in a patient with high-grade serous ovarian carcinoma: diagnostic challenges and management insights.
BMJ Case Rep

Cardiology, East Cheshire NHS Trust, Macclesfield, UK.
Non-bacterial thrombotic endocarditis (NBTE) is characterised by sterile vegetations on heart valves and often emerges in hypercoagulable states like malignancy. It is frequently underdiagnosed and only comes to light during postmortem examination. Early diagnosis and treatment with anticoagulation can help lower mortality.

Background: Venous thromboembolism (VTE) is a significant preventable cause of postoperative morbidity and mortality after major abdominopelvic surgery that calls for extended VTE prophylaxis (eVTEp). Literature suggests that significant racial disparities may exist in post-operative care.
Objective: The study sought to examine if racial disparities exist in the administration of eVTEp after hysterectomy in a statewide collaborative.
Histological differences among thrombi in thrombotic diseases.
Curr Opin Hematol

Department of Pathology, Section of Oncopathology and Morphological Pathology, Faculty of Medicine, University of Miyazaki, Miyazaki, Japan.
Purpose Of Review: This review aims to summarize the histological differences among thrombi in acute myocardial infarction, ischemic stroke, venous thromboembolism, and amniotic fluid embolism, a newly identified thrombosis.
Recent Findings: Acute coronary thrombi have a small size, are enriched in platelets and fibrin, and show the presence of fibrin and von Willebrand factor, but not collagen, at plaque rupture sites. Symptomatic deep vein thrombi are large and exhibit various phases of time-dependent histological changes.
