When umbilical cord entanglement occurs, ultrasound examination may reveal a U-shaped or V-shaped entanglement. The V-shape and U-shape both indicate that the umbilical cord is wrapped around the neck once. In such cases, there is no need for excessive anxiety. Sometimes the cord may unwind by itself as the fetal position changes, loosening or alleviating the entanglement. It is important to regularly visit the hospital for prenatal check-ups, rest adequately, enhance nutrition, and adopt a left lateral position to improve placental blood supply.
