The 2 cases prenatal ultrasound diagnosis of OEIS complex (omphalocele (O) + exstrophy of the cloaca
(E) + imperforate anus (I) + spinal defect (S)) in the first trimester are presented. The problems of differential
prenatal diagnosis and prognosis, possibility of early diagnostic complex detection are discussed.
The case of prenatal ultrasound diagnosis of partial aplasia of the parietal bones of the skull in the second
trimester of pregnancy is presented. Questions of prenatal differential diagnosis and prognosis are discussed
from the point of view of possible embryogenesis of this pathology.
The case of prenatal ultrasound diagnosis of intraventricular hemorrhage of the third degree in the fetus
at 35 weeks of gestation is presented. The child died after birth. The article discusses prenatal diagnosis and
prognosis for children in this pathology.
Despite the rapid technological advance, the expansion of prenatal ultrasound diagnosis, as well as the
accumulation of experience by both domestic and foreign experts, prenatal recognition of true knots of the
umbilical cord causes significant difficulties. Three cases of successful ultrasound diagnosis of true knots of the
umbilical cord and brief review of the literature are presented.
The case of prenatal ultrasound diagnosis of fetal superior occipital encephalocele at 19 weeks of gestation
is presented. The pregnancy was terminated at 20 weeks of gestation. An external examination of the abortus
confirmed the prenatal ultrasound diagnosis.
The prenatal ultrasound diagnosis of large multilocular interhemispheric arachnoid cyst at 34 weeks of
gestation is presented. No other anomalies were noticed. Patient was scheduled for the cesarean section. An
infant was undergone the surgery with fenestration of the cyst three months later. In this case, arachnoid cyst
had an excellent outcome and was not associated with neurological or cognitive impairment.
Seven cases of ultrasound diagnosis of velamentous insertion (VCI) of the umbilical cord at singleton
pregnancies on 21–34 weeks of gestation are presented. The ultrasound picture two of the VIC types is
presented: fixed in 5 cases and free in 2 cases. In one case the VCI was in the lower third of the uterus and
the wound has been diagnosed the vasa previa. In other cases, the VCI was in middle third of the uterus.
In all cases delivery was at 37–39.1 weeks of gestation. In 4 cases Cesarean sections were performed. In two
of the VCI cases elective Ce sarean sections were performed for the following indications: previous Cesarean
section and vasa previa. VCI can reliably be detected prenatally by gray-scale and color Doppler ultrasound.
For fixed VCI located in the middle-upper of the uterus, no change in standard obstetrical management seems
to be required.
Main prenatal ultrasound differential patterns of congenital heart diseases including interventricular septal
defect and dextroposed aorta are presented.
Two cases of prenatal ultrasound diagnosis of left atrial isomerism in the second trimester of gestation is
presented. These two cases were in combination with pulmonary atresia and right aortic arch. Left atrial isomerism
was identify by the digit-like shape of the left and right atrial appendages. The pulmonary atresia was identified
on the basis of reverse flow in small pulmonary artery. A right aortic was identified by “U”-shaped confluence
of aorta and ductus arteriosus in view of three vessels and trachea. The trachea was located between the vessels.
The pregnancies were terminated and prenatal diagnosis was conformed at autopsy
