It Is Normal For A 9.5 Cm BPD Result In A 39-week-old Fetus?
I want to ask at 39 weeks of gestation. My fetal BPD is 9.5cm with enough amniotic fluid, the doctor just said how come it’s rather big huh. Then at 40weeks, the BPD became 9.7. The doctor directly suggested to have a cesarean section, he said my amniotic fluid was plenty. Another doctor said that I could have a normal birth and there were no abnormalities. Is BPD that much normal / hydrocephalus?
Biparietal diameter (BPD) is one way to measure the age and weight of a fetus. Ultrasound measures the body parts of the fetus to look for the age and weight. Biparietal means measuring the circumference of the fetal head. The amount of BPD varies. In certain national races whose body size is bigger, then the possibility of fetal BPD is also greater. Generally BPD at 37-40 weeks' gestation is around 9.5 cm. This value can certainly shift a little.
BPD whose values are far below or above normal, may indicate abnormalities in the brain and head. If it's only based on BPD numbers, then your fetus may be normal. However, you must consult further with the doctor who treats you. It may be that doctors find other signs in the direction of hydrocephalus. Whenever you decide to give birth normally, then if there are problems in the middle of the delivery process, the doctor may have to do an emergency operation. Hydrocephalus is certain or not can only be checked when the baby is born.
Thus a brief explanation from me, hopefully enough help. Regards.
