Summary
Pathological changes in fetal circulation, like absent or reversed diastolic flow, signal high fetal risk. Doctors recommend watchful waiting for absent umbilical artery flow but immediate C-section for reversed flow.
Area of Science:
- Perinatology
- Fetal Medicine
- Doppler Ultrasound
Background:
- Foetoplacental circulation is crucial for fetal development.
- Pathological alterations can compromise fetal well-being.
- Doppler velocimetry is a key tool for assessing fetal circulation.
Observation:
- Zero flow or reversed diastolic flow in umbilical artery or fetal aorta indicates significant risk.
- Continuous fetal monitoring (CTG) and assessment of fetal movements are vital.
- Doppler measurements provide objective data on circulatory status.
Findings:
- Absent end-diastolic flow in the umbilical artery or fetal aorta suggests a need for careful management.
- Reversed end-diastolic flow is a critical sign of severe fetal compromise.
- The study correlates Doppler findings with fetal risk stratification.
Implications:
- Management strategies should be tailored based on Doppler flow patterns.
- Postponing delivery with intensive monitoring is feasible for absent flow.
- Immediate Cesarean section is indicated upon detection of reversed flow to mitigate fetal risk.
