Patient's question:
Doctor, how are you?I am currently 31 weeks pregnant, and the ultrasound shows that the fetus's biparietal diameter is 8.1 cm, the thigh length is 5.8 cm, and it is in the occiput posterior position. Is this normal?
Doctor's answer:
??????Hello, the normal is: the fetus's head is down, and the occiput (i.e., the back of the head) faces the left or right front of the mother's pelvis. If the fetus's occiput faces the left or right back of the mother's pelvis, it is called left occiput posterior (LOP) or right occiput posterior (ROP), which is a type of abnormal and may likely lead to difficult labor. Generally, doctors recommend that women with risk signs during prenatal examinations maintain personal hygiene and avoid sexual activity. Additionally, patients should create an environment conducive to emotional stability and stress relief. Wishing the patient a healthy delivery.
