Due to the nonspecific clinical picture, cases of a long and difficult journey to this diagnosis are not exclusive. In large studies have shown that the most frequent symptom of pulmonary embolism shortness of breath. However, it is not always associated with doctors of different specialties with the need to exclude this diagnosis, purposefully collect anamnesis, identify risk factors. Modern low-dose oral contraceptives are considered quite prosperous in terms of the development of thrombotic complications and cause a slight (1020%) increase in fibrinogen concentration, factors VII, VIII and X, as well as a decrease in the content of active protein S by 1020%.

In this regard, it is important to provide a combined effect on the prognosis of the pathology of the patients and the chosen method of contraception.
