Differential Diagnosis for 35 Weeks Pregnancy with Late Decelerations

Single Most Likely Diagnosis

  • Uteroplacental Insufficiency: This is the most likely diagnosis, as late decelerations are a classic sign of uteroplacental insufficiency, where the placenta is not functioning properly, leading to fetal distress.

Other Likely Diagnoses

  • Fetal Growth Restriction (FGR): FGR can cause late decelerations due to the fetus not receiving enough oxygen and nutrients.
  • Preeclampsia: Preeclampsia can cause uteroplacental insufficiency, leading to late decelerations.
  • Placental Abruption: Placental abruption can cause fetal distress, leading to late decelerations.

Do Not Miss Diagnoses

  • Umbilical Cord Compression: Although less likely, umbilical cord compression can cause late decelerations and is a potentially life-threatening condition if not promptly addressed.
  • Fetal Anemia: Fetal anemia can cause fetal distress, leading to late decelerations, and is a critical condition that requires immediate attention.

Rare Diagnoses

  • Fetal Congenital Anomalies: Certain fetal congenital anomalies, such as cardiac anomalies, can cause fetal distress, leading to late decelerations.
  • Maternal Medical Conditions: Certain maternal medical conditions, such as chronic hypertension or renal disease, can increase the risk of uteroplacental insufficiency and late decelerations.

Management

Management of late decelerations in a 35-week pregnancy involves close monitoring of the fetus, including:

  • Continuous fetal heart rate monitoring
  • Biophysical profile (BPP) assessment
  • Umbilical artery Doppler assessment
  • Fetal movement counting
  • Consideration of immediate delivery if the fetus is in distress or if the mother's condition worsens.
