Treatment Overview
Hypertension in pregnancy, whether chronic, gestational, or associated with preeclampsia, can significantly impact placental function and fetal development. Elevated maternal blood pressure often leads to reduced uteroplacental blood flow, which may cause Fetal Growth Restriction (FGR)—a condition where the baby does not grow at the expected rate inside the womb.
In Korea, Fetal-Growth Surveillance Programs form an essential part of hypertension-in-pregnancy management. These programs use advanced ultrasound imaging, Doppler velocimetry, and AI-assisted growth tracking systems to assess fetal size, growth velocity, and placental health in real time. Korean hospitals integrate maternal-fetal medicine expertise with high-resolution imaging technology to ensure that fetal well-being is monitored with precision and consistency throughout the pregnancy.
This proactive surveillance system allows for early detection of growth deviations, timely interventions, and safer delivery outcomes for both mother and baby.
Purpose & Benefits
Purpose:
- To monitor fetal growth and detect early signs of intrauterine growth restriction (IUGR).
- To evaluate placental function and ensure adequate oxygen and nutrient delivery.
- To guide clinical decisions regarding delivery timing and maternal management.
- To reduce perinatal risks associated with hypertension and placental insufficiency.
- To improve both maternal and neonatal outcomes in high-risk pregnancies.
Benefits:
- Early intervention: Identifies growth restriction before it becomes critical.
- Improved fetal outcomes: Optimizes delivery timing to prevent stillbirth or hypoxia.
- Continuous maternal support: Regular monitoring reduces anxiety and improves adherence.
- Data-driven precision: Advanced imaging ensures accurate fetal size and Doppler evaluation.
- Reduced NICU admissions: Controlled delivery planning improves neonatal stability.
- Enhanced safety: Prevents complications such as preterm birth or emergency cesarean delivery.
Ideal Candidates
Fetal-growth surveillance is highly recommended for:
- Pregnant women with chronic or gestational hypertension.
- Those diagnosed with preeclampsia or HELLP syndrome.
- Women with a history of fetal growth restriction or preterm delivery.
- Mothers with autoimmune or renal disorders affecting placental blood flow.
- Advanced maternal age (≥35 years).
- Women carrying multiple pregnancies (twins or more).
- Patients with diabetes or vascular disorders complicating blood flow to the fetus.
In Korea, all women diagnosed with hypertension in pregnancy are automatically enrolled in fetal-growth monitoring protocols from the second trimester onward.
Possible Risks & Considerations
- Minimal risk: Fetal-growth surveillance is entirely non-invasive and safe for both mother and baby.
- Emotional concern: Frequent testing may cause anxiety; Korean hospitals provide counseling and education for reassurance.
- False growth variation: Temporary differences in measurement may occur; consistent follow-up ensures accurate interpretation.
- Need for continuity: Repeated assessments are necessary for reliable growth trend analysis.
Korean obstetric teams address these considerations with compassion, ensuring that mothers receive both technical accuracy and emotional support.
Medical & Diagnostic Techniques Used in Korea
Korea employs state-of-the-art imaging and monitoring systems to ensure comprehensive fetal growth evaluation in pregnancies complicated by hypertension.
Key Diagnostic Components Include:
1. Ultrasound Biometry
- Biparietal Diameter (BPD): Measurement of fetal head width.
- Head Circumference (HC): Evaluates brain and skull growth.
- Abdominal Circumference (AC): Indicates fetal nutritional status and liver growth.
- Femur Length (FL): Assesses skeletal development.
- Estimated Fetal Weight (EFW): Calculated through integrated biometric data.
Korean obstetric centers use high-frequency 3D and 4D ultrasound systems for enhanced image clarity and measurement accuracy.
2. Doppler Flow Studies
- Umbilical Artery Doppler: Evaluates placental resistance and oxygen delivery.
- Middle Cerebral Artery (MCA) Doppler: Assesses fetal brain perfusion.
- Uterine Artery Doppler: Detects placental insufficiency early in pregnancy.
- Ductus Venosus Flow: Monitors cardiac and hemodynamic function in high-risk fetuses.
Doppler studies help predict adverse outcomes and guide the timing of delivery.
3. Fetal Growth Curves and AI Analysis
- Customized Korean growth charts: Based on large-scale national data for precise percentile comparison.
- AI-integrated software: Tracks fetal growth velocity, detects deviations, and alerts clinicians of potential IUGR.
- Real-time trend visualization: Allows for early adjustments in maternal management or delivery planning.
4. Maternal and Placental Evaluation
- Amniotic Fluid Index (AFI): Monitors fetal environment and hydration.
- Placental grading: Evaluates structure and function using grayscale imaging.
- Maternal blood flow analysis: Correlates vascular resistance with fetal growth rate.
Recovery & Aftercare
- Regular monitoring: Depending on severity, ultrasounds are performed every 2–4 weeks, or weekly in severe hypertension.
- Lifestyle adjustments: Nutritional and rest recommendations support placental blood flow.
- Medication optimization: Antihypertensive therapy adjusted to maintain uteroplacental perfusion.
- Hospitalization when needed: For close observation in cases of significant growth restriction.
- Delivery planning: Decisions regarding induction or cesarean section are based on fetal well-being and gestational age.
- Postnatal evaluation: Neonates born from hypertensive pregnancies undergo growth and metabolic assessments after birth.
Korea’s structured aftercare programs ensure smooth transitions from prenatal monitoring to neonatal care.
Results & Longevity
- High detection rates: Over 90% of growth-restricted fetuses are identified before term.
- Improved neonatal survival: Early intervention significantly reduces morbidity and mortality.
- Reduced emergency deliveries: Continuous monitoring allows for proactive delivery decisions.
- Long-term maternal benefit: Stable blood pressure and fewer complications during labor.
- Sustained neonatal health: Infants born from monitored pregnancies demonstrate better postnatal growth and development.
Korea’s integrated fetal growth surveillance system provides exceptional maternal-fetal outcomes with one of the highest success rates globally.
Procedure Process in Korea
1. Baseline Evaluation
After hypertension is diagnosed, baseline fetal ultrasound and Doppler studies are performed to establish growth parameters.
2. Scheduled Surveillance
Regular scans are scheduled every 2–4 weeks depending on hypertension severity and fetal condition.
3. Fetal Growth Charting
Measurements are compared with Korean population-based growth standards, and growth velocity is analyzed.
4. Doppler and Biochemical Monitoring
Doppler readings, maternal biomarkers, and blood pressure levels are correlated for comprehensive assessment.
5. Clinical Decision-Making
If growth restriction or abnormal blood flow is detected, doctors initiate early intervention, modify medications, or recommend hospital admission.
6. Delivery Planning and Neonatal Care
Timing of delivery is optimized to balance maternal safety and fetal maturity, with neonatal specialists on standby for immediate care.
