fetoscopy
Pronunciation: fee-TOS-koh-pee
Minimally invasive endoscopic procedure allowing direct visualization and treatment of the fetus within the uterus.
Full Definition
Fetoscopy is an advanced surgical technique that uses a thin, flexible endoscope inserted through the maternal abdomen and uterine wall to directly visualize and treat fetal conditions in utero. This procedure enables interventions such as laser ablation for twin-to-twin transfusion syndrome, tracheal balloon occlusion for congenital diaphragmatic hernia, and repair of neural tube defects. Fetoscopy is performed under local or regional anesthesia with ultrasound guidance and requires specialized expertise in fetal surgery centers. While offering therapeutic options for previously untreatable conditions, the procedure carries risks including preterm labor, infection, and membrane rupture.
Usage
Usage note: Distinguish from open fetal surgery. Requires specialized training and equipment.
