Patient's question:
Is oligohydramnios caused by umbilical cord torsion?Doctor's answer:
Hello, generally, an ultrasound description of a "W"-shaped nuchal cord indentation indicates that the umbilical cord is wrapped around the neck two times. Umbilical cord is very common clinically, and it may increase the risk of fetal hypoxia and difficult labor. If oligohydramnios occurs in the early stages of pregnancy, the fetal membranes may adhere to the fetus, causing severe fetal malformations. In the middle and late stages, the buffering effect of amniotic fluid disappears, and the pressure of the uterus can directly act on the fetus, leading to conditions such as torticollis, kyphosis, macroglossia, and. The most common cause of reduced amniotic fluid is placental aging, and drinking more water can help.
