Ultrasonographic signs of poor pregnancy outcome

Abstract

The advantages of high resolution ultrasonography are that it allows more precise diagnosis of any abnormalities in early pregnancy. The frequency of spontaneous interruptions of the development of the reproductive process is very high, especially during the initial stages. It is calculated that, considering the shortcoming of the fecundation, of each 100 potential pregnancies, only 31 will reach full term with a live fetus. The frequency of abortion, considering this as the spontaneous interruption of a pregnancy before the fetus has reached viability, depends therefore on the approach that we use to define that pregnancy exists.
