Fetoscopic laser photocoagulation (FLP) of placental anastomoses is a well-established procedure for twin-to-twin transfusion syndrome that improves fetal outcome with rare maternal complications. However, fetal hydrops can develop even after FLP, and mirror syndrome can occur, indicating that both the fetal and maternal courses should be monitored after FLP.
