Controlled amnioreduction for twin-to-twin transfusion syndrome

Feto-Fetal Transfusion Syndrome in Multiple Pregnancies

Not applicable Interventional Tel-Aviv Sourasky Medical Center · NCT04148859

This study tests if a procedure that removes extra amniotic fluid can help treat twin-to-twin transfusion syndrome in pregnant women with identical twins and improve the long-term health of the babies.

What this trial studies

This study investigates the effectiveness of a controlled amnioreduction procedure for treating twin-to-twin transfusion syndrome (TTTS) in pregnancies with monochorionic twins. The approach involves measuring amniotic pressure while removing fluid to alleviate complications associated with TTTS. Eleven patients with severe TTTS at stages II and III of the Quintero classification were enrolled, and their umbilical artery S/D ratios were monitored throughout the procedure. The long-term neurodevelopmental outcomes of the surviving twins were assessed through a health questionnaire.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women with severe twin-to-twin transfusion syndrome.

Not a fit: Patients with pregnancies that have malformations or genetic pathologies may not benefit from this study.

Why it matters

Potential benefit: If successful, this procedure could significantly improve outcomes for twins affected by TTTS, potentially reducing the risk of preterm delivery and neurodevelopmental deficits.

How similar studies have performed: Other studies have explored similar interventions for TTTS, indicating potential for success, though this specific approach may be novel.
