P45.09: Application of three-dimensional fetal echocardiography in second and third trimesters

Transabdominal chorionic villus biopsy in second and third trimesters of pregnancy to determine fetal karyotype.

Transabdominal chorionic villus biopsy is an established method of obtaining material for analysing fetal chromosomes in the first trimester of pregnancy but has not been widely used for karyotyping in the second and third trimesters, when rapid results are required. The technique was evaluated in two groups of patients, comprising 106 at risk of having a fetus with chromosomal anomalies (105) ...

Three- and four-dimensional fetal echocardiography.

The rapid continuing development of 3-dimensional ultrasound imaging technologies has extended capabilities of fetal cardiac scanning beyond 2-dimensional imaging technologies and now provides a wide array of analytic possibilities. The acquisition of the 3D volume information is based on initial application of 2-dimensional imaging techniques including grey scale, Doppler, Power Doppler and B-...

Fetal dorsalis pedis artery velocimetry in the second and third trimesters.

OBJECTIVES This study aimed to establish reference ranges for Doppler parameters of the fetal dorsalis pedis artery and to compare them with those of the anterior tibial artery. METHODS Dorsalis pedis artery velocimetry was performed in 138 singleton fetuses. Intraobserver repeatability coefficients and differences between measurements of bilateral legs were also evaluated. Comparisons were m...

Sonographic determination of fetal gender in the second and third trimesters in a private hospital in Enugu, southeast Nigeria

Fetal behavior assessed in all three trimesters of normal pregnancy by four-dimensional ultrasonography.

AIM To assess fetal behavior in all three trimesters of normal pregnancy and to investigate the continuation of behavior from fetal to neonatal period. METHODS One hundred out of 130 pregnant women in all trimesters with singleton pregnancy were assigned for the investigation. All recordings were performed in the morning, after two hours of fasting. Video recordings of newborns were made whil...
