Abstract:
In a severely growth-retarded fetus, repeated Doppler ultrasound examinations from the 23rd week of gestation on, showed normal and highly pathological blood flow velocities in the umbilical artery. A caesarean section performed in the 39th week of gestation revealed two true umbilical cord knots. Sonographic screening for umbilical cord knots may be valuable in similar cases. The use of color Doppler could help to visualize the entire course of the umbilical cord.
