Patient population:
Children (under 18 years of age) presenting with thrombosis will be included in the registry. The patients may have had a previous episode of thrombosis or be new cases. All patients will require consent signed by a parent or legal guardian. Patients must have clinically or radiologically identified documented thrombosis.
Primary outcome measure(s) Determine the incidence, distribution of cases and epidemiology of neonatal and paediatric thrombosis in the UK, measured as timepoint of entry to the registry.
Secondary outcome measure(s) 1. Identifying associated risk factors in paediatric thrombosis
2. Treatment practices currently used
3. Morbidity with outcome data
4. Mortality data

Measured both at the time of entry and follow-up over time in cases that would be otherwise reviewed upto a year or longer if there are any long term complications.
