This paper is a review of contemporary scientific publications that deal with association of oral and non-oral forms of combined hormonal contraceptives with thrombotic events risk. Basing on the data analyzed, the following conclusion was made: in case of accurate adherence to medical eligibility criteria and adequate risk factors evaluation the use of combined hormonal contraceptives including vaginal ring NuvaRing leads to clinically nonsignificant thrombosis risk while the benefits of these medications overweigh risks of cardiovascular events.
Thus, the absolute risk of the use of combined hormonal contraceptives for women of reproductive age is extremely low (1-3 cases per 10 000 women). The risk of deaths as a result of venous thromboembolism while taking combined hormonal contraceptives is also low: the probability of death from venous thromboembolism is increased to 1 in 100 000 women if a relative risk level is 2. Increased risk of venous thromboembolism during pregnancy and the postpartum period are 29–30 cases per 10 000 women.
