Absence of the portal system in a first trimester case associated with hygroma and aorto-umbilical fistula. (A): Transverse plane of the upper abdomen with color Doppler applied, showing umbilical cord insertion, stomach, the prominent hepatic artery and no afferent liver venous perfusion; (B): midsagittal plane reconstructed from a three-dimensional volume acquisition were the crown-rump ...

These entanglements can be visualized with ultrasound. Torsion – This term refers to the twisting of the umbilical around itself. Torsion of the umbilical cord is very common (especially in ...
“I pushed three times … and she came out with her umbilical cord wrapped around her neck several times, Joy, 24, said on the Thursday, February 22, episode of the “Viall Files” podcast.

In the second trimester, a standard ultrasound exam typically includes: [12] Fetal number, including number of amnionic sacs and chorionic sacs for multiple gestations; Fetal cardiac activity; Fetal position relative to the uterus and cervix; Location and appearance of the placenta, including site of umbilical cord insertion when possible
