The fetal pole is a thickening on the margin of the yolk sac of a fetus during pregnancy. It is usually identified at six weeks with vaginal ultrasound and at six and a half weeks with abdominal ultrasound. [1] However, it is not unheard of for the fetal pole to not be visible until about 9 weeks.
Many other fetal outcomes have been studied, including Apgar score (a quick assessment of a newborn's health status) at 5 minutes and length of hospitalization after delivery. While both measures are worse for newborns delivered after cord prolapse, [ 8 ] it is unclear what effect this has in the long-term.
Measurement of fetal length (known as the crown-rump length) Fetal number, including number of amnionic sacs and chorionic sacs for multiple gestations; Embryonic/fetal cardiac activity; Assessment of embryonic/fetal anatomy appropriate for the first trimester; Evaluation of the maternal uterus, tubes, ovaries, and surrounding structures
With obstetric ultrasonography the gestational sac (intrauterine fluid collection) can be visualized at 4.5 to 5 weeks gestation, the yolk sac at 5 to 6 weeks gestation, and fetal pole at 5.5 to 6 weeks gestation.
The fetal circulation is composed of the placenta, umbilical blood vessels encapsulated by the umbilical cord, heart and systemic blood vessels. A major difference between the fetal circulation and postnatal circulation is that the lungs are not used during the fetal stage resulting in the presence of shunts to move oxygenated blood and ...
Years later, Keeler claims Cleary sent her chilling messages on Facebook admitting to the sexual assault. "So I raped you,” Cleary allegedly wrote, per the affidavit.
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 equine stillbirths) but it is not a natural state of the umbilical cord. The umbilical cord can be untwisted at delivery. The average cord has three twists.
The safety of frequent ultrasound scanning has not been confirmed. Despite this, increasing numbers of women are choosing to have additional scans for no medical purpose, such as gender scans, 3D and 4D scans. [27] A normal gestation would reveal a gestational sac, yolk sac, and fetal pole. [28]
