Pulmonary hypoplasia: pathogenesis, diagnosis, and antenatal prediction

M R Lauria, B Gonik, R Romero
Obstetrics and Gynecology 1995, 86 (3): 466-75

OBJECTIVE: To review published data pertaining to the pathogenesis, antenatal prediction, and neonatal diagnosis of pulmonary hypoplasia.

DATA SOURCES: A computerized search of articles published through February 1995 was performed on the MEDLINE data base. Additional sources were identified through cross-referencing.

METHODS OF STUDY SELECTION: All available references were reviewed initially by the authors, and their impact on the clinical significance of this condition was summarized.

DATA EXTRACTION AND SYNTHESIS: Pulmonary hypoplasia can be understood best by first defining the embryology of lung development. Although pulmonary hypoplasia can occur as a primary event, most cases are secondary to congenital anomalies or pregnancy complications. Several methods have been proposed to predict the subsequent occurrence of pulmonary hypoplasia, but no single criterion has adequately confirmed sensitivity and specificity for clinical decision making.

CONCLUSION: For patients with premature rupture of membranes, the gestational age at time of rupture carries the highest risk correlation with subsequent pulmonary hypoplasia.
