Fetal Therapy

Sometimes, a baby will have medical concerns that require special treatment before birth.

EvergreenHealth’s Fetal Therapy program uses non-invasive and surgical procedures to correct or treat conditions that threaten your baby’s health.

Surgical intervention may involve either a procedure on a fetus or on the placenta, as in the case of Twin-to-Twin Transfusion Syndrome (TTTS).
