Fetal surgery

Updated: 2021-03-24

Overview

Fetal surgery is a procedure performed on an unborn baby (fetus) in the uterus (in utero) to help improve the long-term outcome of children with specific birth defects. Because these defects often worsen as a fetus develops, fetal surgery done by a team of experts focuses on treating and improving the conditions before birth.

Why it's done

Before a baby is born, early intervention using fetal surgery can treat life-threatening birth defects and improve outcomes in some cases. For example, if a baby has been diagnosed before birth with spina bifida, surgeons might perform open fetal surgery or a less invasive procedure using a fetoscope.

Risks

Potential risks of the procedure — both the risks to you and those to the unborn baby — should be explained by the doctor. These risks include rupture of the uterus after surgery (uterine rupture), fetal death, operative complications, early labor and potential failure to treat the birth defect.

Results

When done by fetal surgery experts in select babies, this early intervention can have better results than surgery after delivery. This means that children with spina bifida, for example, may be significantly less disabled as they go through life than they would have been if they had surgery after birth.
