Off-label use of a vena caval filter in the SVC in an adolescent with upper deep vein thrombosis


 Vena caval filters remain as a useful tool in patients with deep vein thrombosis and contraindications to anticoagulation. Although they are rarely used in paediatric patients, they have been shown to be safe and effective when used in the inferior vena cava.
 In this case report, we describe the off-label use of a retrievable vena caval filter in the superior vena cava in an adolescent with acute lymphoblastic leukaemia with extensive thrombosis of the right upper neck veins as a means to reduce the risk of pulmonary embolism.
