Abstract
Venous thromboembolism (VTE) is a rare but serious complication of combined hormonal
contraception. While the absolute risk of VTE is low in adolescents, thrombotic events
in contraception users younger than the age of 20 years account for 5 to 10% of total
contraception-related VTE events in population studies, because of the high frequency
of contraception use in adolescents. An increased risk of VTE exists not only with
oral contraceptives, but also the contraceptive patch and vaginal ring. Most adolescents
who experience contraception-related VTE have additional transient or inherited thrombotic
risk factors at the time of VTE. Although the presence of inherited thrombophilia
impacts the risk of contraception-related VTE, thrombophilia screening before contraception
prescribing should be targeted only to high-risk populations. Pediatric institutions,
caregivers, and young women need to be aware of the risk of VTE with estrogen-containing
contraception, and maintain a high index of suspicion for this complication in women
using these agents.
