TTTS Diagnosis and Decision
Coming to terms with TTTS
When their pregnancies became high risk, Nicole and Alyssa came to the Colorado Fetal Care Center. While their stories are unique, their journeys are the same.
See what it was like for these families to receive a twin-to-twin syndrome (TTTS) diagnosis and to say "yes" to fetal surgery.
TTTS: the basics
Twin-to-twin transfusion syndrome (TTTS) is a serious, rare fetal condition that can develop in utero when identical twins share a placenta.
Get an in-depth overview of this disease, along with twin-to-twin syndrome symptoms, what the babies experience, how it's diagnosed and treatment options.
Facing a TTTS diagnosis
We think carrying twins is work enough, which is why we're here to handle the rest.
At our Colorado Fetal Care Center, we offer the most comprehensive, state-of-the-art testing, counseling and treatment for TTTS available. And thanks to our care coordinators, all of your appointments will take place in one day, in one location.
What is TTTS?
Nicholas Behrendt, MD, maternal fetal medicine specialist at our Colorado Fetal Care Center, explains twin-to-twin transfusion syndrome, how it develops, the stages of TTTS and why the disease is dangerous to developing twins.
Your guide to the TTTS stages
The stages of TTTS represent the severity of the fetuses' condition and the complications each baby may experience.
The stage of your babies' TTTS helps your care team to design the optimal treatment plan and to determine whether fetal intervention is necessary.
See what both fetuses experience and which treatments are possible at each TTTS stage.
Signs and symptoms
Difference in amniotic fluid levels: one twin has too much fluid and the other has too little
Potential intervention
- Monitor closely via frequent ultrasounds
- Amnioreduction (drainage of amniotic fluid)
Signs and symptoms
Donor twin's bladder isn't visible
Potential intervention
- Monitor closely via frequent ultrasounds
- Amnioreduction
- Laser procedure
Signs and symptoms
Abnormal blood flow in the umbilical cords and/or abnormalities in fetal heart function
Potential intervention
Laser procedure followed by amnioreduction
Signs and symptoms
Fetal hydrops: abnormal fluid accumulation for either fetus in the skin, heart, lungs or abdomen
Potential intervention
Laser procedure followed by amnioreduction
Signs and symptoms
Loss of one or both fetuses
Potential intervention
Possible evaluation of surviving fetus and further planning
Note: Potential fetal intervention relies on many factors during evaluation and therefore may vary. Ask your doctor to learn more about the Cincinnati Modification of Quintero Staging System that we use at Children's Colorado. This helps determine what fetal interventions could be possible according to your unique case of TTTS.
Choosing a fetal care center
All fetal care centers aren't alike. Some may only do evaluations or diagnostics, while others may not have a depth of experience treating your babies' fetal condition, meaning you may need to travel elsewhere for treatment.
Before you entrust a fetal care center with your babies' future, make sure they have the capabilities, technologies and expertise to care for you and your babies throughout – and even after – your pregnancy.
Watch to learn what questions you should ask before choosing a fetal care center.
