Research linePediatric trombosis
DepartmentPediatric hematology
Research Institute(s)AR&D

DescriptionThe research line focuses on two topics: anticoagulation in children and long-term outcomes after thrombosis.
In our anticoagulation research, we strive to determine the optimal dosage for children of, among other things, low-molecular-weight heparin, with the fewest side effects. We also investigate how to treat thrombosis as optimally as possible. This way, we aim to ensure that children have the best possible outcome from their thrombosis.
In our long-term outcome studies, we examine the complications children develop with different types of thrombosis. A pulmonary embolism causes very different symptoms than a thrombosis in the leg. By accurately identifying the symptoms children experience after their thrombosis, and the risk factors for developing them, we can tailor follow-up to the anticipated problems for each child.
