Fetal bronchopulmonary malformations

Abstract

The majority of these fetal lung masses are isolated findings that partially regress during intrauterine life. With adequate postnatal surveillance and eventual surgery the prognosis is good.

Prediction of neonatal respiratory distress in pregnancies complicated by fetal lung masses

“…Congenital lung masses have an incidence of approximately 1 in 15 000 pregnancies . Because some lung lesions, especially those causing mediastinal shift, can be associated with fetal hydrops, preterm delivery, and neonatal respiratory distress, characterizing the severity of the lesion based on prenatal imaging is warranted.…”

“…Factors such as the lesion volume, congenital pulmonary airway malformation volume ratio (CVR), observed to expected total lung volumes, and lesion characteristics (e.g. macrocystic vs microcystic) have been previously described, mostly in single center studies …”

A case of concomitant intralobar bronchopulmonary sequestration and situs inversus totalis

“…Intralobar sequestration accounts for 75% of pulmonary sequestration. It shares the same pleural investment with the normal lung, and the veins usually drain into the pulmonary venous system . In contrast, extralobar sequestrations have a distinct pleural encasement, and their venous drainage is into the systemic veins .…”

“…It shares the same pleural investment with the normal lung, and the veins usually drain into the pulmonary venous system . In contrast, extralobar sequestrations have a distinct pleural encasement, and their venous drainage is into the systemic veins . Extralobar sequestration is found on the left side in 90% of cases and is usually related to the left hemidiaphragm, while the sequestration is located in the left lower lobe near the posterobasal segment in two‐thirds of patients with the intralobar form.…”

Management Options for Fetal Bronchopulmonary Sequestration

“…Searches of Medline and Embase were performed to identify all studies in the English language that reported on the expectant and invasive management of fetuses diagnosed with BPS. In the case of fetuses managed expectantly, only reports of at least two fetuses were considered [ 1 , 10 , 17 , 18 , 19 , 22 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ].…”
