    Pediatric Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE)

    Is deep vein thrombosis common in the pediatric population?
    The short answer is no. 

    What is the likelihood of developing DVT in children? 
    In a study of Korean hospitals, which included 3611 children with cancer over a 15 year period, only 0.9% developed  venous thromboembolism. 

    What is the cause of DVT or venous thromboembolism in the pedistric population ? 

    The vast majority of children diagnosed with VTE have multiple risk factors for thromboembolism.
    Less than 5% of children with VTE have no provoking factor identified. Ths means that they lack a predisposing condition such as an inherited thrombophilic disorder. 

    Whart is the incidence of pulmonary embolism in children? 
    The incidence of pulmonary embolism is lower in children, but when it is diagnosed, mortality remains substantial at 8–10%.

    At what age (when) does the incidence of venous thromboembolism increase ?
    The incidence of VTE remains low until patients enter their third decade of life.
