Prenatal Diagnosis of a True Knot of the Umbilical Cord in Twins Pregnancy

Background: True knot of the umbilical cord is an uncommon finding, which is difficult to diagnose antenatally. The appropriate management of patients with a sonographically identified true knot is yet to be determined.
Case: We present a twin pregnancy, in which antenatal diagnosis of a true knot of the umbilical cord was made at 33 weeks’ gestation. Fetal Doppler examination showed an absence of end diastolic flow in the umbilical artery of the second twin.
Conclusion: The appropriate management of patients with a true knot identified prenatally is unclear. Once diagnosis is suspected, further fetal surveillance is warranted.
