Fetal intrauterine deaths occur every 16 s worldwide with an annual incidence of 2.6 million cases. There are two recommended classifications for its estimation: Causes of Death and Associated Conditions (CODAC) and Relevant Conditions at the Time of Death (ReCoDe). CODAC classifies fetal deaths into 10 categories, while ReCoDe classifies them into nine groups. Domestic scientists recommend the following risk factors for fetal death analysis: non-maternal, fetal, complications of pregnancy, unexplained etiology related to social status, extra-genital diseases, with a history of obstetric and gynecological complications. The current risk factors are classified as modifiable, unmodifiable or potentially modifiable (MFR, nMFR, pMFR). MFRs are controllable and manageable by the patient and include social status and maternal habits (smoking, alcoholism, drug abuse). According to the majority of authors, the nMFRs include the age of the pregnant woman, heredity, congenital malformations, a history of reproductive losses, sexual infantilism. Potentially modifiable factors (pMFR) of risk factors are endometriosis, infectious-inflammatory diseases, arterial hypertension and diabetes mellitus. The assessment of the intrauterine condition of the fetus is a challenge. To diagnose fetal failure the following methods are recommended: instrumental (ultrasound, cardiotocography), biochemical and functional tests (cold, with physical effort, breath-delay, breathing out).
