Fetal medicine: Intrauterine fetal demise following laser treatment in twin‐to‐twin transfusion syndrome

Abstract

IUFD of one or both twins occurred in 45 of 120 (38%) cases of severe TTTS treated by laser. In these, separation of the placental circulations was incomplete in at least 22% (10/45) of the cases. Umbilical artery Doppler abnormalities before laser were found to be risk factors for the donors' demise following the procedure.
