[Fetal hypotrophy dopplerometry].

Area of Science:

• Perinatology
• Fetal Medicine
• Obstetrics

Background:

• Intrauterine growth retardation (IUGR) is a significant concern in high-risk pregnancies.
• Placental insufficiency is a common cause of IUGR, necessitating careful monitoring.
• Doppler velocimetry is a key tool for assessing fetoplacental circulation.

Purpose of the Study:

• To longitudinally analyze the progression of dopplerometric abnormalities in intrauterine growth retardation (IUGR) cases.
• To correlate dopplerometric findings with the severity and progression of placental insufficiency.
• To evaluate the utility of dynamic follow-up in managing IUGR.

Main Methods:

• Prospective study involving 77 pregnant women with IUGR due to placental insufficiency.
• Longitudinal monitoring of dopplerometric abnormalities in umbilical artery (UA) and cerebroplacental ratio (CPR).
• Classification of patients into three types based on the progression of placental insufficiency.

Main Results:

• 486 dopplerometric measurements were performed across 77 patients.
• Mild placental insufficiency showed a progression interval of 31 days (n=21).
• Progressive and severe placental insufficiency had shorter intervals (18 and 8 days, respectively) with a wider spectrum of abnormalities.

Conclusions:

• The gestational week of initial abnormality and the interval to subsequent changes are crucial for assessing placental insufficiency severity.
• Dynamic follow-up of dopplerometric abnormalities allows for better risk evaluation and anticipation of disease progression.
• Timely interventions based on dynamic monitoring can help prevent adverse perinatal outcomes.
