Management of prenatally diagnosed XXXX .

@entity1 @entity4 @entity2977
We have treated four prenatally diagnosed cases of extensive @entity2977 ( @entity2977 ) of the lung. The first case in 1982 was associated with severe fetal @entity4 . After thoracentesis at 31 weeks of gestation abruptio placentae occurred, and a female baby was delivered by cesarean section. She underwent a right lower lobectomy, but soon died. The second baby without @entity4 , diagnosed as having @entity2977 at 26 weeks of gestation, was followed conservatively until full term. After birth, it was necessary to treat the baby @entity1 with extracorporeal membrane oxygenation (ECMO), but he survived. The third baby with fetal @entity4 had an indwelling drainage catheter inserted into the @entity2977 at 27 weeks of gestation. The @entity4 subsided and the baby was delivered at 37 weeks of gestation. He was allowed to breathe spontaneously, but was intubated 16 hours after birth. A right lower lobectomy was successfully performed 24 hours after delivery. The fourth baby without fetal @entity4 was followed conservatively until delivery. He underwent left lower lobectomy successfully on the 4th day of life. Although management of prenatally diagnosed @entity2977 varies among @entity1 , insertion of an indwelling catheter into the cyst appears to be the treatment of choice if indicated; the catheter can be maintained for as long as 10 weeks, as shown in Case 3. Cases of @entity2977 without fetal @entity4 should also be treated carefully, because persistent fetal circulation may occur postnatally.
