congenital diaphragmatic hernia
causes
pulmonary parenchymal
vascular hypoplasia
procedure
abdominal patch
allowed to add abdominal contents w/o increasing intrabdominal pressure
which compromises ductus venous BF
liver herniated
usually unsuccessful :warning:
required new technique
congenital high airway obstruction syndrome (CHAOS)
fetal tracheal occlusion impedes the normal egree of fetal lung fluid
results in expansion of hypoplastic lung
this technique replaced abdominal patch cause
palliative fetal surgical procedure
enhances lung growth to improve postnatal survival
less extensive
allows postponement of definitive repair until after birth
Plug the lung until it grows
fetal pulmonary fluid acculmates
expands lung
pushes viscera out of thorax
trachea is occluded
ballon inflated at 26 to 28 weeks
before birth pops ballon
or at 34 weeks pop ballon
