Formulate a team approach with the surgical team ahead of time. A range of options for antenatal intervention are available included drains or thoracoamniotic shunts to reduce the size of cystic lesions or fluid collections causing fetal compromise, open fetal surgery by fetoscopy or open fetal surgery to perform pulmonary lobectomy to resect large masses causing fetal compromise, EXIT procedure for pulmonary lobectomy to resect masses that will interfere with neonatal resuscitation. Postnatal resection may include complete resection by lobectomy, pneumonectomy in cases of extensive multilobar involvement or segmental resection. Discuss the need for lung isolation with the surgeon. Frequently, surgeons retract and/or pack the operative lung as needed for operative exposure.
