Overview

Venous thromboembolism (VTE) is relatively uncommon in adolescent age. In our survey we evaluate presence of particular risk factors for VTE in 72 consecutive patients aged 14 to 18 years, who were treated for their first VTE episode at our department in 7 years period (2004–2010).

In median, our patients had 2 risk factors (RF) (range 0–5 RF/patient), more often acquired ones. Most frequent RF were: high FVIII in 44 %, combined oral hormonal contraception (42 % of all, but 65% of girls), FV Leiden 28 %, injury 19 % and infection 18 %. We also recorded thrombosis location – 50 % patients had deep vein thrombosis in distal lower extremities veins and 28 % ileofemoral thrombosis. Other locations were much less frequent. 11 % patients had pulmonary embolism, one girl died. Annual incidence of VTE in our region has been calculated relatively high – 15.6 per 100000 adolescents.

This finding supports increasing occurrence of VTE in adolescents, as well as expected distribution of particular RF for VTE. Acquired RF were behind VTE in more then 80 % of events in our cohort.

Key words:
thrombosis, adolescent, risk factors
