Hidrotórax fetal secundario a secuestro pulmonar intralobar: terapia fetal mediante escleroterapia percutánea bajo guía ecográfica

Abstract

Pulmonary sequestration is a mass of non-functioning lung tissue that does not communicate with the tracheobronchial tree and has an aberrant blood supply that comes from the systemic circulation. We present the case of a 34-year-old pregnant woman, with a pregnancy of 25 weeks, with an antenatal diagnosis of pulmonary sequestration with pleural effusion, mediastinal compression, cardiac dextroposition and polyhydramnios. Fetal intervention was performed using percutaneous sclerotherapy, successfully. After 4 weeks, there was evidence of absence of pleural effusion, heart in normal position. The pregnancy ended satisfactorily with a newborn in stable condition. Pulmonary sequestration can present a rapid evolution of mass growth, which produces mediastinal compression, fetal hydrops and polyhydramnios, which produces approximately 100% fetal mortality. It is important to know all available therapeutic options, including percutaneous sclerotherapy under ultrasound guidance, to improve fetal prognosis.
