A respiratory malformation characterized by the presence of both bronchi (albeit rudimentary) and alveoli in an under-developed lobe. Both the size and the weight of the lung are reduced. The true prevalence is not well known (1.4% of all births according to Knox et al. 13), but in cases of premature rupture of membranes at 15-28 weeks gestation, the reported prevalence of pulmonary hypoplasia ranges from 9 to 28%. Factors that contribute to pulmonary hypoplasia include adequate volume of the thoracic cavity, pulmonary fluid dynamics, and abnormal fetal breathing movements.
Biomarker and diagnostic research for pulmonary hypoplasia has been reported in the published literature.
5 clinical trials registered, 1 recruiting. Interventions under study include medical devices. Pipeline includes 1 PHASE3, 4 NA. Research is primarily sponsored by academic and government institutions.
