Summary
Transabdominal amnioinfusion is a safe procedure for treating oligohydramnios in pregnancy. It significantly improved the diagnosis of fetal malformations, aiding patient management and delivery decisions.
Area of Science:
- Perinatology
- Maternal-Fetal Medicine
- Diagnostic Imaging
Background:
- Oligohydramnios, a condition of low amniotic fluid, poses risks to fetal development and pregnancy outcomes.
- Accurate diagnosis of fetal malformations is crucial for effective management of high-risk pregnancies.
Purpose of the Study:
- To evaluate the outcomes of transabdominal amnioinfusion in pregnant patients diagnosed with oligohydramnios.
- To assess the safety and efficacy of ultrasound-guided transabdominal amnioinfusion.
Main Methods:
- A prospective observational study included 80 cases of oligohydramnios treated with transabdominal amnioinfusion.
- Procedures were performed between 2011 and 2016 by a single operator across two centers.
- Mean gestational age at treatment was 24 weeks; some patients received multiple infusions.
Main Results:
- The mean interval between the first infusion and delivery was 31 days.
- Perinatal and neonatal mortality rates were 45% and 35%, respectively.
- Chorioamnioitis occurred in five cases; final diagnoses were often made post-amnioinfusion.
Conclusions:
- Transabdominal amnioinfusion demonstrated a high safety profile.
- Despite high perinatal mortality (attributed to major fetal malformations), the procedure significantly improved diagnostic accuracy for congenital fetal malformations.
- Enhanced diagnostic accuracy positively impacted patient management, particularly regarding delivery mode.
