Dr. Ruano writes: "The statistics for babies that had FETO vs those who did not undergo FETO are based on some studies from Europe, South America and now some data from United States. My experience considering the use of ECMO or not, is that our results have demonstrated that FETO improves the survival rate for babies with severe CDH from 10% without FETO to 50-60% after FETO in a population that we did not use ECMO. Here in the United States, we are investigating that still; however, our initial results demonstrated that the survival rate was 80% after FETO versus 20% without FETO. In addition, our initial study in the USA showed that the need for ECMO was 70% without FETO versus 30% after FETO."
