Resumen:

Bronchopulmonary sequestration is a congenital developmental lung pathology characterized by a supernumerary lung tissue that receives its blood supply by a systemic feeding artery usually originating from the descending aorta. The diagnosis may be establish by a routine fetal ultrasound during the second or third trimester through identification of a homogeneous, hyperechoic, solid lung mass with an aberrant feeding systemic artery. It generally has a good prognosis and a high rate of spontaneous resolution, but the prognosis depends mainly on the mass size and the presence of fetal fluid effusions. In the presence of hydrothorax or hydrops, perinatal mortality is almost 100%. For such high-risk cases, fetal surgery by full laser ablation of the feeding artery has been demonstrated to be the best procedure to improve prognosis and to avoid the need of postnatal intervention. At the same time, cases that have a good prognosis with expectant management during pregnancy require a postnatal surgical resection of the lung mass. © 2018 Elsevier Inc. All rights reserved.
