Insights
Placental insufficiency causes impaired fetal growth and poor perinatal outcomes. Future research will develop risk models to optimize individualized treatment strategies for fetal growth restriction.
Area of Science:
- Obstetrics and Gynecology
- Perinatal Medicine
- Fetal Medicine
Background:
- Placental insufficiency leads to impaired fetal growth, a significant cause of adverse perinatal outcomes.
- Current interventions do not alter the underlying pathophysiology of fetal growth restriction.
- Monitoring strategies for early-onset fetal growth restriction (FGR) aim to optimize delivery timing via cardiotocography and Doppler ultrasound.
Purpose of the Study:
- To address the challenge of identifying fetuses with late-onset FGR who require expedited delivery due to immediate hypoxia risk.
- To highlight the need for improved risk stratification in late-onset FGR.
- To outline future research directions for optimizing individualized treatment strategies.
Main Methods:
- Review of current monitoring practices for early-onset FGR (cardiotocography, Doppler ultrasound).
- Discussion of challenges in risk identification for late-onset FGR.
- Conceptual framework for future risk model development.
Main Results:
- No current intervention modifies the pathophysiology of FGR.
- Identifying fetuses at risk for hypoxia in late-onset FGR remains challenging.
- The need for integrated risk models incorporating multiple variables is emphasized.
Conclusions:
- Optimizing individualized treatment for FGR requires better risk assessment.
- Future studies will focus on integrating various monitoring variables and prognosticators into risk models.
- The goal is to improve perinatal outcomes in fetuses with FGR.
Abstract:
Impaired fetal growth owing to placental insufficiency is a major contributor to adverse perinatal outcomes. No intervention is available that improves outcomes by changing the pathophysiologic process. Monitoring in early-onset fetal growth restriction (FGR) focuses on optimizing the timing of iatrogenic preterm delivery using cardiotocography and Doppler ultrasound. In late-onset FGR, identifying the fetus at risk for immediate hypoxia and who benefits from expedited delivery is challenging. It is likely that studies in the next decade will provide evidence how to best integrate different monitoring variables and other prognosticators in risk models that are aimed to optimize individual treatment strategies.
