Can prenatal checkups detect the problem of umbilical cord around the leg?

　　Prenatal examination, also known as antenatal checkup, can usually detect fetal position and obvious cases of nuchal leg cord (umbilical cord wrapped around the fetal leg) during examination. However, when the fetal position is uncooperative or the cord wrapping is slight, prenatal examination may have difficulty in making an accurate determination. If any abnormalities are detected, timely medical consultation is recommended. Detailed explanation is as follows:

　　When the fetal position is favorable and the umbilical cord is clearly wrapped around the leg, this condition can usually be detected during prenatal examination. Through ultrasound examination, doctors can clearly observe the position and status of the fetus within the uterus, including whether the umbilical cord is wrapped around the fetal legs. If the cord wrapping is obvious, the doctor will clearly indicate it in the examination report and provide corresponding advice and management measures.

　　When the fetal position is unfavorable and the umbilical cord wrapping is slight, prenatal examination may not accurately determine the situation. Because the fetus has considerable mobility within the uterus, if its position is not conducive to observation or the cord is only slightly wrapped around the leg, the doctor may not be able to clearly visualize the condition during the examination. In addition, ultrasound examination results can also be affected by various factors including equipment quality, physician experience, and examination duration, thus having a certain margin of error.

　　Pregnant women should maintain a positive and optimistic mindset, follow a balanced diet, engage in moderate exercise, undergo regular prenatal checkups, and follow professional medical advice to ensure the health of both mother and baby.
