Clinical Trial Summary

In this study is tested the validity of placental vascular indices obtained from placenta ultrasonographic sphere biopsy and entire placenta investigation.

Description:

Although, to this date, there have been a number of human placental studies that concerned the evaluation of placental 3 dimensional power Doppler vascularization with the use of VOCAL technique, but there was no one in which placental vasculature has been compared between the sonobiopsy and whole placental volume.

Intervention

Diagnostic Test:
• 3 dimensional ultrasound investigation
Images that contributed to the determination of placental volume and 3-DPD indices were obtained at the time of visit. All 3-D scans ultrasound measurements were performed by a Voluson 730 Expert ultrasound machine equipped with a multifrequency probe (2-5 MHz) to acquire images. Each sample was examined using 3-D rendering mode, in which the colour and gray value information was processed and combined to supply 3-D image. For laterally located placentas, the investigator positioned the transducer on a slight lateral inclination to obtain proper images. Power Doppler window was placed over the placenta to map the vascular tree from basal to chorionic plates. The 3-D static volume box was placed over the entire placenta volume. The sweep angle was set at maximum 70°. Each image was recovered from the disk in succession for processing. During gestation, the investigator recorded one sample from each patient.
• 2 dimensional ultrasound investigation
The two-dimensional (2-D) transabdominal conventional study provided data about fetal position, biometry, body movements and fetal heart rate as well as placental localization. The factorial default setting 'Obstetrics' was applied in 2-D mode.
