Can a wheel-shaped placenta be delivered naturally?

Pregnant women have a very low chance of developing a rota placenta, which refers to a concave center on the fetal surface of the embryo, surrounded by a thickened gray ring. The ring is composed of bifolded amnion and chorion, with degenerated decidua and fibers in between. Inside the ring, the fetal face is a normal shape and is attached to the fetal umbilical cord. Large blood vessels can be seen ending at the edge of the ring, and the rolled and thickened amniotic villi often cause embryonic bleeding and infarction. So, can a wheel-shaped placenta be delivered naturally?

Wheel-shaped placenta usually occurs in the second half of pregnancy. The actual cause is unclear. Pay attention to whether there is umbilical cord prolapse and do B-ultrasound examinations regularly to check the umbilical cord blood flow. If the examination is normal, there is no major problem and it will not affect the baby's development. Whether you can choose natural delivery should be comprehensively judged at the time of delivery. You should communicate more with the attending physician, observe closely, and have regular prenatal checkups.

Vaginal delivery is not recommended for incomplete rotaform placenta. It is very easy to cause incomplete embryo drop and cause internal bleeding. It's best to have another caesarean section. A little safer. It is recommended that in cases like yours, a caesarean section is the best option. In order to prevent internal bleeding, it will have a certain impact on the fetus or the pregnant woman. If the baby is already full-term now, a caesarean section can be performed.

A rotund placenta refers to a placenta in which the center of the fetal surface is concave and surrounded by a thick gray ring.

The incidence of rostral placenta is less than 1/6,000. It refers to the concave center of the fetal surface of the embryo, surrounded by a thickened gray ring. The ring is composed of bifolded amnion and chorion, with degenerated decidua and fiber in between. Inside the ring, the fetal face is a normal shape and is attached to the fetal umbilical cord. Large blood vessels can be seen ending at the edge of the ring, and the rolled and thickened amniotic villi often cause embryonic bleeding and infarction. Wheel-shaped placenta can be divided into two categories: complete type (forming a complete ring of embryonic tissue) and partial type (forming an incomplete ring of embryonic tissue). Partial type wheel-shaped placenta does not cause any fetal abnormalities, while complete type wheel-shaped placenta is associated with placental abruption, premature birth, IUGR, fetal malformations, and increased perinatal mortality, but complete type wheel-shaped placenta is rare. The dysmorphic sonographic changes of the wheel-shaped placenta are that the edge of the embryo protrudes into the amniotic cavity in a ring-shaped strip or block-like shape, and the internal echo is similar to the intrinsic echo of the embryo. If there is bleeding or infarction, there may be anechoic or low-echo areas inside. Wheel-shaped placenta, especially the edge of the embryo protruding into the amniotic cavity in a ring-shaped strip, has similarities with amniotic band syndrome in the sonogram, which is easy to cause misdiagnosis. The two should be carefully distinguished.

Ultrasound diagnosis: 1. The sonographic changes of the dysmorphic placenta are that the edge of the embryo protrudes into the amniotic cavity in a ring or block shape, and the internal echo is similar to the intrinsic echo of the embryo. If there is bleeding or infarction, there may be no echo or low echo area inside. 2. The camera performs a radial scan of the embryo, that is, a 360-degree observation of the edge of the embryo, which is helpful in assessing the degree of rotund placenta. For example, in the posterior placenta, due to the influence of the embryo, information may not be displayed and misdiagnosis may occur.
