The objective of our study was to determine the impact of laser therapy for twin-to-twin transfusion syndrome (TTTs) on subsequent pregnancies.


This was a monocentric retrospective observational study. Women treated by laser fetoscopy for TTTs were asked to answer a postal questionnaire about subsequent pregnancies. The primary outcome was fecundity (number of pregnancies and time to pregnancy). We also assessed pregnancy complications, birth weight, and gestational age at delivery. Pregnancy complications included the following: threatened preterm labor, preeclampsia, placenta accreta, postpartum hemorrhage, and psychological disorders. Our study population was compared with an external control group made up of mothers of monochorionic twins without TTTs.


We included 122 cases managed at the Necker Hospital between 2008 and 2012 and 39 controls. The median conception time was longer in the TTTs group (6.4 ± 11.1 versus 2 ± 1.6 months, P = .03). The numbers of live childbirths at the end of those pregnancies were equivalent (77.6% versus 66.7%, P = .56). Birth weight (3317 ± 726 versus 3240 ± 382 g, P = .81) and gestational age at delivery (38.2 ± 6.8 WG versus 39.5 ± 1.2 WG, P = .64) were similar, with no increase of obstetrical complications compared with the control group.


Twin-to-twin transfusion syndrome and its treatment do not seem to impact subsequent pregnancies.
