[Contraception and thrombophilia]

Abstract

The risk of thromboembolic events (TE) is increased by acquired or inherited thrombophilias (IT). We know that some hormonal contraceptives also increase the risk of thrombosis, thus, the use of such contraceptives are discussed as contraindications in women with IT. TEs are infrequent events in children and adolescents and in the majority of cases are associated with secondary complications from underlying chronic illness. Although adolescents are not typically considered to be at high-risk for TE, this cohort is frequently using hormonal contraception, leading to an increased risk in cases with unknown IT. The risk of TE with pregnancy alone is higher than associated with combined hormonal contraception. Progestin-only methods have not been found to increase the risk of TE with only moderate changes of coagulation proteins compared to normal reference values.

Conclusion: Thrombophilic women are good candidates for progestin-only contraceptive methods.
