Prenatal interventions for fetal lung lesions.

Area of Science:

• Perinatology
• Fetal Medicine
• Pediatric Surgery

Background:

• High-resolution ultrasound and routine fetal anatomy scans increase detection of fetal thoracic abnormalities.
• Congenital cystic adenomatoid malformation and bronchopulmonary sequestration are common fetal lung lesions.
• Historically, smaller lung tumors were often missed, causing parental and physician anxiety.

Purpose of the Study:

• To review the evaluation and management of fetal lung lesions.
• To discuss the prognosis and treatment options for congenital lung abnormalities.
• To provide an overview of fetal therapy for severe cases.

Main Methods:

• Review of current literature on fetal lung lesion detection and management.
• Analysis of diagnostic criteria and imaging techniques for fetal thoracic masses.
• Examination of prenatal intervention strategies and their outcomes.

Main Results:

• The majority of detected fetal lung lesions have an excellent prognosis without intervention.
• Congenital cystic adenomatoid malformation and bronchopulmonary sequestration are the most frequent diagnoses.
• Fetal therapy for severe cases (e.g., with hydrops) can achieve survival rates exceeding 50%.

Conclusions:

• Increased detection of fetal lung lesions via ultrasound is common.
• Most fetal lung lesions have a favorable prognosis, alleviating anxiety.
• Prenatal intervention is available and effective for a small subset of fetuses with poor prognoses.
