Abstract
Prenatal identification of lung abnormalities has increased with prenatal surveillance. Treatment usually requires serial ultrasound observation but in rare situations in utero therapy may be required for fetal survival. We review the genetics, prenatal evaluation, and treatment of lung abnormalities with congenital cystic adenomatoid malformation (CCAM). Other lung lesions, bronchopulmonary sequestration (BPS), hybrid lesions involving both malformations, congenital lobar emphysema (CLE), are briefly included as differential diagnosis options. Outcome of fetuses identified to have CCAM lung abnormalities resulting in fetal hydrops and having in utero therapy (thoracoamniotic shunting, fetal thoracotomy, EXIT delivery) are discussed. In the appropriate situation, this maternal fetal surgery approach for CCAM is life‐saving for the affected fetus with acceptable maternal morbidity risks in the present and future pregnancies. © 2005 Wiley‐Liss, Inc.
