MIAMI BEACH -- Fetoscopic endoluminal tracheal occlusion, or FETO, results in "impressive" relative increases in lung volume in cases of severe congenital diaphragmatic hernia, Dr. Jacques C. Jani reported at the annual meeting of the Society for Maternal-Fetal Medicine.
In eight fetuses with the condition who underwent FETO, and who were followed by regular magnetic resonance imaging beginning at 24-26 weeks' gestation, the mean relative increase in lung volume from first MRI to near birth was 110%, compared with 22% in eight fetuses managed expectantly, said Dr. Jani of the University Hospital Gasthuisberg, Leuven, Belgium.
The mean maximal increase in lung volume in the FETO patients was observed 4 weeks after treatment. The volume decreased by 23%, compared with the posttreatment maximum, following balloon removal, which typically occurred at 34 weeks' gestation, but volume remained higher than in those managed expectantly.
The fetuses in ...
