Ultrasonographic diagnosis of miscarriage
Miscarriage is the most frequent complication in
pregnancy. Ultrasound is the main diagnostic tool used
in diagnosing the various types of miscarriage and to
some extent, in the diagnosis of the cause. Knowledge
of the normal sonographic features of early pregnancy
is essential for diagnosing pathologic development.
The physiologic development of the endometrium, of
the gestational and yolk sac, of embryonic growth and
heartbeat are sonographically documented. The sonographic
signs of miscarriage and their prognostic value
for pregnancy outcome are discussed in this article.
If there is only a single sonographic sign of miscarriage
and the clinical features are asymptomatic, a follow-up
examination should be offered before the abortion is
confirmed. The only sonographic sign that is a confirmation
of miscarriage is the loss of fetal heart action.
Doppler examination of the uterine arteries shows a
large overlapping of the normal and pathologic velocity
flow profiles in normal pregnancies and pregnancies
that end in miscarriage. This examination is, therefore,
of no prospective value in the diagnosis of fetal loss.
3D studies reveal additional information in the first
trimester of pregnancy. Nevertheless, there are very
few data on the subject.
