BACKGROUND: In spite of significant therapeutic progress, the prognosis of congenital diaphragmatic hernia (CDH) remains pejorative in those forms in which the liver is herniated into the chest. The severity of this malformation relies on the pulmonary hypoplasia due to lung compression by the herniated viscera in the thoracic cavity, particularly the liver. This impaired growth concerns the whole pulmonary tissue, i.e. both the vessels and the alveoli. For the clinician, it is mandatory to know the evolution pattern of the lesions, to define the best time to treat them. AIM AND METHOD: The aim of this work was to study the pulmonary lesions along the gestation in fetuses affected byCDH. This morphological study was carried out on 134 human fetuses aged from 22 to 40 weeks of gestation. Anatomical and histological analysis focused on lung weight, alveolar count and wall thickness of the distal vessels. RESULTS: The results indicate that the pulmonary lesions worsen as the pregnancy continues, particularly beyond 30 weeks of gestation. CONCLUSION: Such an anatomical study should bring to the clinicians useful data to enhance the management of the patients.
