Clinical Significance of Hypocoiled Umbilical Cord

Definition and Normal Parameters

• The American College of Radiology recommends umbilical artery Doppler assessment after 20 weeks for fetuses with hypocoiled umbilical cords, as part of enhanced fetal surveillance protocol 1

Clinical Management Algorithm

• The American College of Radiology suggests initiating enhanced fetal surveillance protocol, including serial growth ultrasounds every 3-4 weeks and antenatal testing (NST/BPP) in the third trimester, for fetuses with hypocoiled umbilical cords 1
• The American College of Radiology recommends preparing for potential intrapartum complications, including continuous electronic fetal monitoring during labor and a lower threshold for interventional delivery if fetal distress develops, for fetuses with hypocoiled umbilical cords 1
