Risk factors determining central venous access device-associated deep vein thrombosis resolution in children: a retrospective study

Conclusion: CVAD-associated DVT resolution in children in the first 6 months since diagnosis was significantly lower if the thrombosis was occlusive, if it was located in the upper extremity, head, and neck veins; if collateral circulation was seen on ultrasound in the first 45 days; and/or when the patient showed less prothrombotic risk factors at diagnosis.What is Known:•The risk factors associated with central venous access device-associated deep vein thrombosis resolution have been hardly evaluated in children.•Current guidelines suggest anticoagulation for a maximum of 3 months in provoked vein thrombosis if the provoking factor is resolved.What is New:•Thrombus resolution was lower if it was occlusive, located in the upper extremity veins, if collateral circulation was seen, and with less prothrombotic risk factors at diagnosis.•To know if the thrombus will resolve after anticoagulation will help to choose whether to initiate and/or continue it or not.
