fetal endoscopic tracheal occlusion
Also written as: FETO — Fetal Endoscopic Tracheal Occlusion
Minimally invasive procedure using fetoscopy to temporarily block the fetal trachea, promoting lung growth in severe congenital diaphragmatic hernia cases.
Full Definition
Fetal endoscopic tracheal occlusion (FETO) is a prenatal surgical technique that involves the temporary placement of a detachable balloon in the fetal trachea via fetoscopy. This occlusion prevents the normal efflux of lung fluid, creating back-pressure that stimulates lung growth and development. The procedure is primarily used to treat severe congenital diaphragmatic hernia where lung hypoplasia threatens fetal survival. The balloon is typically removed before delivery through a second fetoscopic procedure or may be removed during delivery via EXIT procedure.
Usage
Usage note: Often abbreviated as FETO in clinical documentation.
