Duration of the Development of Twin-Twin Transfusion Syndrome

Abstract

Background: It is generally recommended that monochorionic diamniotic (MD) twin pregnancies be followed by ultrasound examination at least every 2 weeks in order to be able to promptly diagnose twin-twin transfusion syndrome (TTTS). In this study, we retrospectively investigated the clinical significance of TTTS developing at < 2 weeks (n = 9) and ≥ 2 weeks (n = 13). Methods: We examined the following potential factors associated with TTTS development: discordance of the crown-rump length at 8 - 11 weeks, the gestational age at the last confirmation of concordant amniotic fluid (AF), the gestational age at TTTS diagnosis, the estimated fetal weight discordance, and AF values at ≤ 3 - 7 days before TTTS diagnosis. Results: There were no significant differences in these variables between the two groups. Conclusion: There were no significant differences in the clinical histories of TTTS developing at < 2 weeks and ≥ 2 weeks in MD twin pregnancy.
