Neonatal Outcome for Laser Coagulation in Twin-to-twin-transfusion Syndrome

Twin-twin transfusion syndrome is one of the most severe complication in monochorionic twin pregnancies and can cause severe impairment of fetal and neonatal outcome. In severe TTTS the fetoscopic laser coagulation is the treatment of choice. Fetoscopic laser coagulation is associated with a morbidity and mortality due to iatronic rupture of membranes as well as iatrogenic placenta insufficiency. This can cause preterm delivery as well as intrauterine fetal demise. An adaption of the fetoscopic tools to reduce the lesions of the amniotic membrane can decrease the risk of PPROM and increase the overall survival.
