Treating previable twin-twin transfusion syndrome with fetoscopic laser surgery: Outcomes following the learning curve

Abstract
Aims: We have performed fetoscopic laser occlusion of chorioangiopagous vessels (FLOC) in previable pregnancies affected by twin-twin transfusion syndrome (TTTS) since 1988. Treatment outcomes obtained after the procedure's learning curve are presented and compared to those from other centers performing FLOC or other treatment methods.
