Middle cerebral artery peak systolic velocity: technique and variability.
OBJECTIVE Assessment of the middle cerebral artery (MCA) peak systolic velocity (PSV) can accurately diagnose fetal anemia and has decreased the number of invasive procedures, such as amniocentesis and cordocentesis. The objective of this investigation was to evaluate the intraobserver and interobserver variability as a measure of reproducibility of MCA PSV. The technique of correctly sampling ...
متن کاملPrediction of fetal anemia in rhesus disease by measurement of fetal middle cerebral artery peak systolic velocity.
OBJECTIVE In red blood cell (RBC) isoimmunized pregnancies fetal anemia is associated with a hyperdynamic circulation. The aim of the present study was to examine further the possible value of fetal middle cerebral artery peak systolic velocity (MCA-PSV) in the management of affected pregnancies. METHODS A reference range of fetal MCA-PSV with gestation was constructed from the study of 813 n...
متن کاملFetal middle cerebral artery peak systolic velocity in the investigation of non-immune hydrops.
OBJECTIVE In some cases of non-immune hydrops there is congenital or acquired fetal anemia. The aim of this study was to investigate the potential value of fetal middle cerebral artery peak systolic velocity (MCA-PSV) in the assessment and management of non-immune hydrops due to anemia. METHODS Fetal MCA-PSV and fetal hemoglobin concentration, in blood obtained by cordocentesis, were measured...
متن کاملMiddle cerebral artery peak systolic velocity for the diagnosis of fetal anemia: the untold story.
The use of the middle cerebral artery peak systolic velocity (MCA-PSV) for the diagnosis of fetal anemia has been one of the few discoveries in fetal medicine that is changing the standard of care in the management of affected pregnancies1. This has led to a more than 70% reduction in the number of invasive tests, which often cause fetal death, in the assessment of red-cell alloimmunized pregna...
متن کاملNomogram of fetal middle cerebral artery peak systolic velocity in a Brazilian population*
OBJECTIVE: To determine a reference curve for the peak systolic velocity of fetal middle cerebral artery. MATERIALS AND METHODS: The authors developed a cross-sectional study with 143 healthy pregnant women between the 23rd and 35th gestational weeks. A bidimensional axial scan of the fetal skull was performed, including the thalami and pellucid septum. Subsequently, the middle cerebral artery ...
