The frequency of spontaneous abortion, when it is considered
from its very beginning, along with the theoretical knowledge
of the causes of the abortion, should provide a perspective to
the obstetrician that, performing a sonographic exploration finds
discoveries that cannot correspond to those characterizing a
The precocity of the realization of sonographic explorations
in the pregnancy will allow diagnosis of many more cases of
spontaneous interruptions of the development of pregnancy.
New sonographic imaging techniques including threedimensional
(3D) sonography can provide additional information
regarding the presence of structural anomalies via 3D volume
acquisition, like craniofacial deformities, clefts, neural tube
defects, abdominal wall defects, and caudal regression syndrome.
It may give further details regarding the timing of embryonic/
fetal demise in early pregnancy. Sufficient informational value is
regularly obtained in cases having a crown-rump length >8 mm.
