We estimated the disease-specific incidence rate, in-hospital case fatality rates, length of stay (LOS), and related admission to the intensive care unit (ICU). Furthermore, we evaluated therapeutic procedures.<\/jats:p>\n                  <jats:p>The incidence rate of incident VTE-related hospitalizations was 4.9 (95%CI 4.7; 5.2) per 100,000 children and adolescents per year. The in-hospital case fatality rate was 4.0% (95%CI 3.2; 5.0); the median LOS was 8 (Q1\u2013Q3 4\u201324) days. Systemic thrombolysis, catheter-directed treatment, and inferior vena cava filters were used in less than 15% of patients. Among patients receiving systemic thrombolysis, the in-hospital case fatality rate was 19.4% (95%CI 12.6; 28.5), whereas patients managed with catheter-directed treatment had a rate of 8.0% (95%CI 3.2; 18.8). 39.3% of patients were admitted to ICU. Age- and sex-specific differences in incidence rate, proportion of hospital admissions, and in-hospital case fatality rate were observed, particularly among infants aged\u2009&lt;\u20091\u00a0year and adolescents aged 15\u201319\u00a0years.<\/jats:p>\n                  <jats:p>\n                    <jats:italic>Conclusion<\/jats:italic>\n                    :VTE among children and adolescents is rare with age- and sex-specific differences in incidence.
