Summary

Fetal surgery has evolved over the last three decades from an innovative and ambitious concept into an accepted reality. The metamorphosis from curiosity to sought-after therapy has been driven by the refinement of techniques used in open hysterotomy surgeries, advances in the available technology and instrumentation, expansion of the repertoire of minimally invasive image-guided percutaneous interventions, and the development of safe and effective fetoscopic surgical procedures. Serious complications associated with the early era fetal surgery procedures such as intraoperative fetal death, abruptio placentae and pulmonary edema have been largely eliminated, and extreme preterm delivery (<28 weeks) has been significantly reduced. Specialized anesthesia protocols and intraoperative management algorithms have led to improved fetal tolerance of these procedures, and advancements in neonatal intensive care have dramatically improved neonatal outcomes.
