“…The outcome in cases with HPE is generally poor, with high rates of mortality, however, some children survive for many years. Higher mortality will correlate with the severity of brain malformations and facial malformations, the presence of genetic abnormalities and the presence of other congenital malformations [29][30][31]. We also observed this trend in our case series, with intrauterine mortality reaching 37% (4 cases out of 11 in which pregnancy was not terminated).…”

Aim: Holoprosencephaly (HPE) is the most common brain malformation. A wide spectrum of anatomical variants are characterized by a lack of midline separation of the cerebral hemispheres. The aim of this study was to assess the ultrasound diagnostic criteria for HPE.Material and method: A database of 175 fetuses with central nervous system anomalies identified by ultrasound was collected retrospectively from 2006 to 2016 in this multicenter, retrospective, observational study. Among them 18 cases (10.2%) with HPE were identified.Results: The prevalence of HPE was 2.5:10.000 with the sex distributionmale:female of 1:1.6. Six cases were alobar subtype, 3 were semilobar, 7 were lobar and 2 were middle interhemispheric variant. In the second trimester, we consider that the abnormal fusion of the lateral ventricles and the absence of the cavum septum pellucidum are the most important landmarks for HPE. Facial abnormalities varied considerably.Conclusion: This study illustrates the heterogeneity of HPE with different cerebral and facial appearances.

“…It is crucial for the management of current pregnancy and to reassure the patient regarding subsequent pregnancies about the sporadic nature of the condition with low recurrence. 3,9,20,49 Undoubtedly, the prenatal diagnosis can reduce the severity of many associated anomalies, allowing a timely therapeutic strategy during pregnancy with fetoscopic band release or intervention immediately after birth. 6 A fetus with amniotic band syndrome should be delivered in a tertiary care center where neonatologists, pediatric surgeons, and orthopedicians are available.…”

Amniotic band syndrome (ABS) is a rare, but serious congenital syndrome complex. It is associated with a wide range of fetal structural anomalies, notably craniofacial and limb anomalies. Early prenatal diagnosis is important to provide accurate information to the parents, predict the prognosis and in some cases perform in-utero lysis of the bands to restore the blood flow to the affected limb. A postnatal multidisciplinary approach involving vascular decompression, reconstructive surgery, prosthesis, and physiotherapy are some of the therapeutic options. It is necessary to consider ABS in prenatal screening with a high index of suspicion as early screening can allow a timely therapeutic strategy and reduce the severity of the associated defects.

Provisional organs (placenta, umbilical cord, amniotic membranes, amniotic fluid) play a significant role during pregnancy. Their normal morpho3functional state is an important condition for normal development and well3being of the fetus, as well as for uncomplicated course of pregnancy. Congenital malformations (CM) and chromosomal abnormalities are major causes of perinatal morbidity and mortality. For fetuses with malformations, dysfunction of the provisional organs (PO) can become critical and affect survival. Expert correct examination of PO during a comprehensive prenatal examination can become a diagnostic and prognostic tool for specialized management of fetuses as patients, and newborns to optimize the system of prenatal dispensary evaluation. Literature review has shown that there are certain patterns of the PO pathology in cases of fetal abnormal development, which require changes in the tactics of prenatal observation and delivery. The variability of morphological/ultrasound changes and clinical outcomes makes it difficult to reach definite diagnosis and make correct decisions about the management of patients in specific cases. Further research is needed to optimize the protocols of ultrasound examinations and prediction of perinatal complications in the pathology of the PO in fetuses with normal and abnormal development. No conflict of interests were declared by the authors. Key words: prenatal diagnosis, provisional organs, placenta, umbilical cord, amniotic membrane, amniotic fluid, vital and lethal congenital malformations, perinatal consequences, fetus.
