There are several techniques used in prenatal surgery, including:
1. Open Fetal Surgery: This involves opening the mother's abdomen and uterus to access the fetus. 2. Minimally Invasive Fetoscopy: This involves using a small camera and instruments inserted through tiny incisions in the uterus. 3. Image-Guided Techniques: These involve using ultrasound or MRI to guide instruments to the fetus.
Each method has its own risks and benefits, and the choice of technique depends on the specific condition being treated.
