pulmonary hypoplasia

Full Definition

Underdevelopment of lung tissue resulting in reduced lung size, decreased alveolar number, and impaired respiratory function at birth. Pulmonary hypoplasia can result from various conditions affecting fetal lung development, including oligohydramnios, congenital diaphragmatic hernia, or chest wall abnormalities. The severity determines postnatal respiratory support requirements and overall prognosis. Some fetal interventions aim to promote lung growth and prevent or minimize pulmonary hypoplasia.
