Pulmonary hypoplasia

DA: 5

Developmental anomaly information

Definition: Pulmonary hypoplasia or aplasia is part of the spectrum of malformations characterized by incomplete development of lung tissue. The severity of the lesion depends on the timing of the insult in relation to the stage of lung development and the presence of other anatomic anomalies. The hypoplastic lung consists of a carina, a malformed bronchial stump, and absent or poorly differentiated distal lung tissue. For lung development to proceed normally, physical space in the fetal thorax must be adequate, and amniotic fluid must be brought into the lung by fetal breathing movements, leading to distension of the developing lung.The true incidence is unknown, but the etiologies (in order of frequency) include prolonged rupture of membranes, fetal renal dysplasias and obstruction, and fetal neuromuscular diseases
