Risk of donor demise after laser therapy for twin–twin transfusion when complicated by growth discordance and abnormal umbilical artery Doppler findings*

Objective: To investigate the natural course of abnormal umbilical artery Doppler (UAD) findings in donor fetuses after laser surgery and the prognostic significance of resolution, persistence, or new onset UAD abnormalities with and without the presence of preoperative growth discordance.Study design: Retrospective cohort study of all monochorionic-diamniotic multi-fetal gestations diagnosed with twin-twin transfusion syndrome (TTTS) undergoing...
