Neonatal Outcome in Twin-To-Twin Transfusion Syndrome Treated with Fetoscopic Laser Occlusion of Vascular Anastomoses

Although perinatal outcome in TTTS has improved after laser therapy, neonatal mortality and morbidity rates remain high. Relative risk for adverse neonatal outcome is increased 2-fold in TTTS treated with laser relative to monochorionic twins without TTTS.
