Prediction of fetal anemia by different thresholds of MCA-PSV and Delta-OD in first and second intrauterine transfusions.
BACKGROUND Our aim was to compare different thresholds of middle cerebral artery peak systolic velocity (MCA-PSV) and amniotic fluid delta optical density (Delta-OD) with fetal hemoglobin (Hb) during first and second intrauterine transfusions (IUT). METHODS We determined serial MCA-PSV and Delta-OD in 27 red blood cell alloimmunized fetuses who needed IUT. Before the second IUT, MCA-PSV was m...

OBJECTIVE To construct monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) twin reference ranges for umbilical artery (UA) pulsatility index (PI), UA resistance index (RI), fetal middle cerebral artery (MCA) PI and peak systolic velocity (PSV) and cerebroplacental ratio (CPR) from 24 weeks' to 38 weeks' gestation and compare these with published normal values for singleton pregnan...
متن کاملRole of MCA-PSV in managing fetal anemias of non-alloimmunized origin
The news that a fetus is normal and healthy on obstetric ultrasound scan brings immeasurable joy and satisfaction to the would be parents. However, this serene bounty can get haunted if the fetus develops signs of anemia. Although red blood cell alloimmunization remains one of the major causes of anemia in the fetus, never the less multiple other causes have been reported in non-alloimmunized p...
متن کاملFirst trimester fetal karyotyping in twin pregnancy.
Fetal chromosome analysis in a twin pregnancy during the first trimester is described. Problems of the reliability of tissue sampling are also discussed. The authors emphasise the advantage of direct cytogenetic analysis from the tissue specimens used for enzyme determination or DNA studies.
متن کاملFetal Hydrops in a Twin Pregnancy
Hydrops fetalis is a well known condition with an extensive list of differential diagnoses. The etiology is divided into immunerelated and nonimmune-related types, and currently almost 90% of cases are associated with the latter category [1]. Among the various nonimmune-related causes, one of the most common are cardiac aberrations [2]. Prenatal ultrasound serves as the initial diagnostic tool ...
