Discover the latest updates to fetal surgery from world-leading experts in Cancun this September.
Ultrasound remains a cornerstone of maternal-fetal medicine, facilitating comprehensive assessment throughout gestation and postnatally. Its critical role extends to diagnosing fetal conditions requiring urgent intervention, often enabling in-utero surgical procedures in order to optimise perinatal outcomes. Advances in fetal surgery increasingly rely on ultrasound for real-time image guidance, particularly in complex interventions involving vital structures such as the brain, heart and spine. As techniques evolve, ultrasound continues to optimize precision in fetal surgical procedures, enhancing both maternal and neonatal prognoses.

General principles of Ultrasound-Guided Procedures
In utero ultrasound-guided procedures have revolutionized antenatal care by enabling diagnosis, management, and treatment of various fetal conditions within the mother's womb using real-time ultrasound imaging.
Ultrasound-Guided Fetal Surgeries: Techniques and Applications
Ultrasound-guided fetal surgeries have transformed prenatal care by offering effective therapeutic options for several major fetal conditions during pregnancy. This overview aims to underline the significance of ultrasound-guided fetal surgeries, their techniques, applications, benefits, and challenges.
Spina bifida
Spina bifida is a defect of the vertebral arches. Most frequently the cavity of the neural tube is open. In a minority of cases the defect is closed by the overlying skin. Open spina bifida results in a U-shaped defect of the vertebrae in the axial plane, and is associated with typical cranial signs and clubfoot.
Enlargement of the vein of Galen
It is the consequence of two types of arteriovenous malformation: the vein of Galen aneurysmal malformation and the pial arteriovenous malformation. The sonographic appearance is similar and the most prominent finding is the enlargement of the vein of Galen, that on Color Doppler contains turbulent blood flow.
Diaphragmatic hernia
Congenital diaphragmatic hernia is a fetal defect associated with a higher risk of mortality due to pulmonary hypertension and lung hypoplasia. Fetal diagnosis is based on demonstration of an abnormality in the thoracic view. Prognosis is based on evaluation of the lung size in the contralateral side of the hernia.
Aortic Stenosis
Aortic Stenosis (AS) is the narrowing of the aortic valve opening, causing a variable degree of left outflow tract obstruction. The underlying pathophysiology is left outflow tract obstruction. The degree of obstruction varies from mild to severe, from an asymptomatic bicuspid valve to critical obstruction.
