Abstract

Aims: Embryonic demise is a frequent complication of the first trimester pregnancy. The purpose of this study was to evaluate the correlation between a serum biomarker, the soluble form of the vasculo-endothelial growth factor (sFlt-1) and the distance between the yolk sac (YS) and embryo (DYSE), determined by ultrasonography., Material and Methods: The study was a prospective case-control study that included 2 groups of patients - the control group with 81 first-trimester pregnancies in evolution and the case group with 89 first-trimester pregnancies with a potentially reserved evolutivity., Results: A correlation between the serum level of sFlt-1 and DYSE in embryos with crown-rump length (CRL) greater than 5 mm was identified, showing that a DYSE ≤3 mm correlates with a low level of sFlt-1 (p<0.05) and a DYSE> 4 mm correlates with an increased level of sFlt-1 (p<0.05)., Conclusions: A low level of sFlt-1 associated with a distance between the embryo and yolk sac of small dimensions, respectively <3 mm, correlates with an increased rate of non-viable embryos. This correlation between an ultrasound and a serum parameter is of great value and brings important information about the viability of firsttrimester pregnancies.

Abstract

Twin reversed arterial perfusion (TRAP) sequence is a rare and severe complication specific to monochorionic twin pregnancies, involving the presence of an acardiac twin and a structurally normal co-twin (pump twin). We report on the case of a33-year-old female with a biamniotic monochorionic twin pregnancy complicated with TRAP sequence and polyhydramnios. The patient underwent fetoscopic termination of the acardiac twin and at 34 gestational weeks (GW) was readmitted with aretroplacental hematoma. The patient gave birth through caesarean section to a living female fetus, weighing 1480 g. To the best of our knowledge, this is the first case reporting a twin pregnancy with TRAP sequence complicated with retroplacental hematoma.

Abstract

The information provided by Doppler ultrasound examination during labor permits the understanding of the mechanisms regarding the physiology and pathophysiology of feto-placental exchange and the fetal adaptive systems. There are certain technical difficulties related to intrapartum Doppler ultrasound examination. The investigated sites are the uterine arteries, umbilical arteries, fetal circulation. In diastole, when intrauterine pressure exceeds maternal diastolic pressure, the perfusion pressure of the uterine artery blood flow is no longer present. A progressive decrease in the diastolic component is seen along with an increase in intrauterine pressure from 10 to 60 mmHg. During premature birth or preeclampsia, there are particular changes in the uterine blood flow. A remarkable stability of the umbilical resistance index is found during labor, which shows the permanent presence of feto-placental exchange. Certain correlations can be established between fetal heart rate changes in labor and Doppler ultrasound aspects at the level of umbilical arteries. Doppler examination confirms the concept of reduced cerebral blood flow by the compression of the fetal skull as a cause of decelerations occurring during labor. The decision regarding the extraction of the fetus can only be made by correlating the results of Doppler ultrasound with the other paraclinical methods for the monitoring of the intrapartum fetal status.
