The aim of this study was to report the results of the first 10 cases of fetoscopic laser surgery for twin-to-twin transfusion syndrome by the Rotunda Hospital Fetal Treatment Programme. All cases of severe TTTS managed by our team from 2006 to 2007 were included. All fetoscopic laser surgeries were performed by a single specialist in fetal medicine. All pregnancies were followed up to pregnancy completion and a minimum of six weeks neonatal life. Laser surgeries were performed with ultrasound guidance and percutaneously using local anaesthesia via a 2.8mm rigid fetoscope. Selective laser ablation of placental vessels was accomplished with a neodymium:YAG laser. The first 10 cases of severe TTTS managed by our team are reported. Laser ablation of placental vessels was accomplished successfully in all cases. Two pregnancies were complicated by preterm premature rupture of membranes before 22 weeks and both pregnancies were lost. Of the remaining 16 fetuses, one was diagnosed with significant ventriculomegaly postoperatively and underwent selective termination in the United Kingdom. The overall intact neonatal survival rate was 65%. Fetoscopic laser ablation of placental vessels for severe twin-to-twin transfusion syndrome is now available in Ireland, and our programme has delivered results that are in keeping with international best practices in this regard.
