Abstract:

Microcystic or solid-looking fetal lung lesions associated with hydrops are associated with a high mortality rate. The most common of these lesions are microcystic congenital cystic adenomatoid malformations and pulmonary sequestrations (PS). Performing open fetal surgery by hysterotomy and lobectomy has, until now, been the only therapeutic option available following diagnosis of these lesions in the second trimester. Here we describe a new minimally invasive technique for the treatment of PS in the second trimester. Laser coagulation of the feeding systemic artery of the sequestration was performed under ultrasound guidance. The blood flow to the lung tumor was successfully arrested and hydrops reversed. The child was born at term and, at the time of writing, was alive and well at 2 years of age.Large PS with hydrops can be treated successfully by ultrasound-guided minimally invasive laser surgery. It is therefore important to utilize color Doppler ultrasound imaging for identification of a systemic feeding blood vessel in solid fetal lung tumors. Published by John Wiley & Sons, Ltd.
