Article Synopsis
- A study investigates the effectiveness of a biweekly ultrasound scan protocol starting at 16 weeks for early detection of twin-twin transfusion syndrome (TTTS) in monochorionic diamniotic (MCDA) pregnancies and assesses outcomes in a large cohort.
- Among 675 monitored pregnancies, 12% developed TTTS, and 90% of those were detected early enough to intervene effectively; however, a small percentage presented at a critical late stage.
- Results show that while survival rates after treatment (fetoscopic laser photocoagulation) are relatively high, they do not fully reflect the overall mortality associated with TTTS; many severe cases exhibited abnormal Doppler findings prior to diagnosis.
Objectives: To report the outcome of selective fetal growth restriction (sFGR) diagnosed according to the new Delphi consensus definition, and determine potential predictors of survival, in a cohort of unselected monochorionic diamniotic twin pregnancies.
Methods: This was a retrospective study of monochorionic diamniotic twin pregnancies followed from the first trimester onward, which were diagnosed with sFGR at 16, 20 or 30 weeks' gestation. sFGR was defined according to the new Delphi consensus criteria as presence of either an estimated fetal weight (EFW) < 3 centile in one twin or at least two of the following: EFW of one twin < 10 centile, abdominal circumference of one twin < 10 centile, EFW discordance ≥ 25% or umbilical artery pulsatility index of the smaller twin > 95 centile.
