1. What is knotted umbilical cord?

During pregnancy, the umbilical cord plays an important role in transporting oxygen and nutrients from the mother to the fetus, ensuring the baby's life while in the womb. However, when the umbilical cord is knotted, it will affect the pregnancy both during pregnancy and during labor.
This is a pathological condition caused by fetal movement in the last trimester of the first trimester. The incidence is about 0.3% to 1% depending on the study. When the umbilical cord is knotted, in most cases it will be loose, and the fetus is usually less affected during pregnancy. But when the umbilical cord is tightened, it will obstruct the fetal circulation, the final result is that the fetus will die in the womb.

Many experts say that it is difficult to determine the exact time when the umbilical cord is knotted. The knotted umbilical cord can form very early from 9-12 weeks of gestation, because at this stage the amniotic fluid volume is more than the fetal volume.
Knotted umbilical cord is difficult to detect in prenatal ultrasound. Depending on the capabilities, qualifications, clinical experience as well as the quality of the ultrasound system, a knotted umbilical cord can be detected.
