RIOS, Lívia Teresa Moreira et al. First trimester pregnancy abnormalities: iconographic essay. Radiol Bras [online]. 2010, vol.43, n.2, pp.125-132. ISSN 1678-7099.

First trimester pregnancy abnormalities may be detected by transvaginal ultrasonography at routine examinations or in cases where abnormal vaginal bleeding is present. Threatened miscarriage is frequently observed in the first trimester, occurring in more than one-third of pregnancies. The advent of high-resolution transvaginal ultrasonography has revolutionized the understanding of the pathophysiology and the management of early pregnancy. This method represents an essential tool for determining the pregnancy viability in cases of threatened miscarriage. An expectant approach in the management of miscarriage could significantly reduce the number of unnecessary evacuations of retained products of conception, depending on the adopted criteria.

Keywords : Miscarriage; Pregnancy abnormalities; Transvaginal ultrasonography.
