Patient's question:
Last menstrual period was on January 11th. Previous NT, triple screen, NIPT, and 4D ultrasound tests were all normal, but a detailed ultrasound at 22 weeks detected a cord cyst. Some doctors recommended amniocentesis, saying it could indicate chromosomal abnormalities and fetal drowning in the late stages of pregnancy. However, amniocentesis carries a risk of miscarriage, which is a bit concerning. Doctor, is it necessary to undergo amniocentesis to further diagnose?Doctor's answer:
Umbilical cord cysts in the second and third trimesters of pregnancy are associated with fetal malformations and aneuploidy. Some studies have shown that up to 50% of cases have umbilical cord cysts. Therefore, if an umbilical cord cyst is detected during the second and third trimesters of pregnancy, it is recommended to perform a detailed fetal chromosome examination. Amniocentesis does carry risks, but the incidence of complications in standard, high-level hospitals is still very low. It is important to maintain a good routine and increase physical exercise in daily life to enhance the body's resistance and immunity.
