This video, presented by Dr. Beth Rymeski of Cincinnati Children's Hospital, details the procedural aspects of Fetal Endoluminal Tracheal Occlusion (FETO). It explains how a fetoscope is used to insert a balloon into the fetal trachea to temporarily block fluid, facilitating lung expansion and preventing pulmonary hypoplasia in CDH babies. The presentation includes real-life video footage, demonstrating critical navigation techniques through fetal anatomy and careful balloon placement.
