Absent or reverse diastolic blood flow velocity (ARFV) in the umbilical artery is a rare condition linked to poor fetal outcomes. Prompt intervention and careful delivery timing are crucial for managing pregnancies with ARFV.

Area of Science:

  • Perinatology
  • Fetal Medicine
  • Obstetrics

Background:

  • Absent or reverse diastolic blood flow velocity (ARFV) in the umbilical artery is a rare condition observed in high-risk pregnancies.
  • This condition is associated with significant adverse fetal outcomes.

Purpose of the Study:

  • To describe the diagnostic and management experience of pregnancies complicated by ARFV.
  • To evaluate the prognostic implications of ARFV on fetal well-being and perinatal outcomes.

Main Methods:

  • Retrospective analysis of 19 pregnancies diagnosed with ARFV in the umbilical artery.
  • Comparison of outcomes between survivors and non-survivors, considering gestational age at delivery, malformations, and delivery mode.

Main Results:

  • ARFV occurred in 2.2% of high-risk patients, with 63.2% of fetuses being small for gestational age (SGD), 26% having malformations or hydrops fetalis, and a 36.8% perinatal mortality rate.
  • Significant differences were observed between survivors and non-survivors regarding gestational age at delivery (33.1 vs. 28.6 weeks), malformation rates (8.3% vs. 57.1%), and Cesarean section rates (91.7% vs. 42.9%).
  • Pregnancy termination was delayed by at least 48 hours in 42.1% of cases, allowing for corticosteroid administration.

Conclusions:

  • ARFV indicates a critical fetal condition necessitating careful consideration for pregnancy termination.
  • Delivery timing and mode should be individualized based on gestational age and fetal/maternal well-being.
