Pregnancy is often described as a journey of hope and anticipation. However, for some families, prenatal tests or scans may reveal conditions that require advanced medical intervention before birth. This is where fetal therapy plays a vital role. Fetal therapy includes medical and surgical procedures performed during pregnancy to treat abnormalities in the baby (fetus) before delivery. These advanced interventions can significantly improve outcomes, reduce complications, and support safer pregnancies.
Today, with cutting-edge imaging, improved diagnostic accuracy, and specialized fetal medicine centres, fetal therapy has become a crucial part of managing high-risk pregnancies, offering both parents and doctors the ability to respond to concerns early and effectively.
What is Fetal Therapy?
Fetal therapy refers to treatments provided to the unborn baby while still inside the uterus. It is typically recommended when the fetus has a treatable condition that could worsen or become life-threatening without early intervention.
Fetal therapy may involve:
Medication therapy administered to the mother
Minimally invasive procedures guided by ultrasound
Fetal surgeries performed inside the womb
These interventions are carefully planned by fetal medicine specialists, maternal-fetal medicine experts, neonatologists, and pediatric surgeons to ensure the best care for both mother and baby.
When is Fetal Therapy Needed?
Fetal therapy is usually considered when:
A fetal abnormality is detected during prenatal screening or fetal ultrasound
The condition could worsen during pregnancy
Early intervention provides a better outcome than post-birth treatment
Delaying treatment may pose risks to the baby’s life or long-term health
Common conditions that may require fetal therapy include:
Twin-to-Twin Transfusion Syndrome (TTTS)
Fetal anemia
Congenital diaphragmatic hernia
Spina bifida
Fetal urinary tract obstruction, such as bladder outlet obstruction
Congenital lung lesions
Types of Fetal Therapy
Fetal therapy procedures can vary from medication-based management to complex fetal surgeries. Below are the most widely used fetal therapy approaches:
1. Maternal Medication Therapy
In this approach, medications are given to the mother, which pass through the placenta and reach the baby.
Examples include:
Medications to treat fetal heart rhythm problems
Steroids to improve lung maturity
Antibiotics for fetal infections
This method is non-invasive and widely used.
2. Fetal Blood Transfusion
If the baby has severe anemia (often due to Rh incompatibility or infection), a blood transfusion can be performed directly into the fetus’s umbilical cord vein under ultrasound guidance.
This procedure helps restore oxygen levels and prevent heart failure in the fetus.
3. Laser Therapy for TTTS
In Twin-to-Twin Transfusion Syndrome, identical twins sharing a placenta may have an imbalance in blood flow.
A minimally invasive fetoscopic laser surgery seals abnormal blood vessels, improving survival and developmental outcomes for both babies.
4. Fetal Surgery for Spina Bifida
Spina bifida occurs when the baby’s spinal cord does not close properly.
Fetal surgery to repair the defect before birth has shown:
Reduced risk of paralysis progression
Improved mobility outcomes after birth
This surgery requires a highly trained fetal surgical team.
5. Shunt Placement for Obstructions
If the baby has excess fluid buildup due to urinary tract obstruction or lung cysts, doctors may insert a shunt to help drain fluid and prevent organ damage.
Benefits of Fetal Therapy
Earlier control of life-threatening fetal conditions
Improved survival rates for high-risk babies
Better long-term development outcomes
Reduction in complications during delivery
Emotional support and preparedness for parents
While fetal therapy is not recommended for every prenatal condition, it has significantly improved outcomes in several complex fetal disorders where early action is critical.
Risks and Considerations
Like any medical procedure, fetal therapy involves risks, including:
Preterm labor
Infection
Surgical complications
Risk to maternal health (rare)
Therefore, decisions are always taken after:
Detailed fetal assessment
Fetal MRI or advanced ultrasound imaging
Genetic counseling
Multi-disciplinary case review
Families are provided complete guidance and emotional support throughout the process.
Role of a Fetal Medicine Centre
Choosing a well-equipped fetal medicine centre ensures:
Accurate diagnosis using advanced imaging (3D/4D ultrasound, Doppler, fetal echocardiography)
Care by fetal medicine specialists trained in prenatal interventions
Seamless collaboration with neonatologists and pediatric surgeons
Supportive counseling and personalized care plans
Such centers create a safe care pathway from pregnancy through delivery and newborn care.
FAQs
1. Is fetal therapy safe?
Most fetal therapy procedures are well-established and performed under strict medical protocols. Your specialist will evaluate risks and benefits before recommending treatment.
2. Does every fetal abnormality require therapy?
No. Some abnormalities only require observation, while others may need treatment before or after birth. Your fetal medicine specialist will guide you.
3. Can fetal therapy cure birth defects?
Some conditions can be corrected or improved significantly before birth, while others require ongoing treatment after delivery.
4. How is fetal surgery different from post-birth surgery?
Fetal surgery can prevent progressive damage before birth and improve outcomes that would not be possible if treatment is delayed until after delivery.
5. What specialists are involved in fetal therapy?
Fetal therapy requires a multidisciplinary team including fetal medicine specialists, pediatric surgeons, obstetricians, neonatologists, anesthesiologists, and genetic counselors.
