Understanding TTTS
What is twin-to-twin transfusion syndrome?
Twin-to-twin transfusion syndrome, or TTTS, is a serious complication that can occur when identical twins share one placenta. Unequal blood flow through placental vessel connections may cause one baby to receive too little blood and the other baby to receive too much.
TTTS is a condition of monochorionic twins — twins sharing one placenta. The first step is always to confirm chorionicity, diagnose the stage correctly, and decide whether the pregnancy needs close monitoring, amnioreduction, laser fetal therapy counselling, or urgent referral.
How TTTS affects the two babies differently
Donor Twin
The baby receiving less blood
The donor twin may have low amniotic fluid, a poorly visible or empty bladder, growth restriction, and abnormal Doppler findings in more advanced disease.
Recipient Twin
The baby receiving excess blood
The recipient twin may have too much amniotic fluid, heart strain, abnormal venous Dopplers, hydrops, or signs of cardiac compromise in severe cases.
Laser Fetal Therapy
What is laser surgery for TTTS?
Fetoscopic laser surgery for TTTS is a specialised fetal therapy procedure. A fetoscope is introduced into the uterus, the abnormal placental vascular connections are identified, and laser energy is used to seal the connecting vessels. The goal is to separate the two fetal circulations as much as possible.
Purpose of laser treatment
The aim is to stop harmful unequal blood sharing between the twins by sealing abnormal placental vascular connections.
Not for every TTTS case
The need for laser depends on TTTS stage, gestational age, fetal wellbeing, cervix length, Dopplers, placental anatomy and counselling.
Counselling and referral planning
Mayflower provides TTTS diagnosis, staging, monitoring and referral coordination for fetal laser therapy when required.
Specialist Staging
What Dr. Kunda evaluates before laser surgery counselling
TTTS management begins with detailed staging. The scan is not just a routine twin scan — it is a structured fetal medicine evaluation of both babies, the placenta, blood flow, amniotic fluid and fetal heart function.
| Assessment Area | What is checked | Why it matters |
|---|---|---|
| Chorionicity | Whether the twins share one placenta and whether the pregnancy is monochorionic diamniotic. | Essential first step TTTS occurs only in monochorionic twins. |
| Amniotic fluid discordance | Deepest vertical pocket around each twin, with donor twin fluid and recipient twin fluid compared. | Core diagnostic clue Fluid imbalance is central to TTTS diagnosis. |
| Bladder visibility | Whether the donor twin bladder is visible, small, intermittently visible or persistently absent. | Bladder visibility helps define disease stage and progression. |
| Doppler studies | Umbilical artery, middle cerebral artery, ductus venosus and venous flow where indicated. | Risk marker Abnormal Dopplers may indicate fetal compromise. |
| Fetal heart assessment | Recipient twin heart size, function, rhythm, valve flow and signs of cardiac strain. | The recipient twin heart may be affected by volume overload. |
| Growth and anatomy | Estimated fetal weights, growth discordance and structural survey of both babies. | Associated problems can influence prognosis and management decisions. |
| Cervical length and placenta | Cervical length, placental location, cord insertions and technical suitability for intervention. | Procedure planning depends on safe access and preterm birth risk. |
Patient Pathway
The Mayflower TTTS care pathway
When TTTS is suspected, the family needs clarity quickly. The pathway below explains how Mayflower helps parents move from uncertainty to an informed plan.
1
Step One
Confirm twin type and TTTS diagnosis
Dr. Kunda confirms whether the twins share one placenta, assesses fluid around each baby, evaluates bladders, fetal growth, fetal anatomy and Dopplers.
2
Step Two
Stage the disease
TTTS stage is assessed using ultrasound markers such as fluid imbalance, bladder visibility, Doppler changes, hydrops and fetal condition.
3
Step Three
Explain management options
Depending on the stage and pregnancy details, options may include close monitoring, amnioreduction, laser fetal therapy referral, neonatal planning or other individualised care.
4
Step Four
Coordinate fetal therapy referral if needed
If laser therapy is appropriate, Mayflower helps with counselling, documentation, scan summaries and referral coordination to an appropriate fetal therapy team.
5
Step Five
Continue post-treatment monitoring
After intervention or conservative management, ongoing surveillance is essential for fetal growth, Doppler studies, recurrent TTTS, TAPS, preterm labour risk and delivery planning.
Advanced twin pregnancy imaging on GE Voluson Signature Expert
TTTS diagnosis requires detailed imaging of both twins, amniotic fluid, placental cord insertions, Dopplers, bladder filling, fetal heart function and interval change. At Mayflower Clinic, Dr. Kunda Shahane uses the GE Voluson Signature Expert platform to support high-resolution fetal assessment and structured surveillance of monochorionic twin pregnancies.
Balanced Counselling
Laser therapy decisions need urgency, but not panic
TTTS can progress quickly, but every decision must be based on diagnosis, stage, fetal condition, gestational age and parental counselling. The aim is to avoid delay without rushing into the wrong treatment.
Possible benefit
Laser therapy may improve outcome in selected TTTS cases by treating the abnormal placental vessel connections.
Procedure-related risks
Risks can include membrane rupture, bleeding, infection, preterm labour, recurrence, fetal compromise or fetal loss.
Need for follow-up
Even after laser therapy, ongoing scans are needed to watch for recurrent TTTS, TAPS, growth restriction and preterm birth risk.
No guaranteed outcome
Laser therapy can improve chances in suitable cases, but it cannot guarantee survival or normal development of one or both babies.
Who Should Book Urgently?
When to seek a TTTS second opinion
Parents should not wait if a scan report mentions monochorionic twins with fluid imbalance, absent bladder, suspected TTTS, hydrops, Doppler abnormality or significant growth discordance.
Unequal amniotic fluid
One twin has very low fluid while the other has excess fluid, especially in a shared-placenta twin pregnancy.
Bladder difference
The donor twin bladder is very small or not visible, while the recipient twin bladder is large or frequently full.
Heart or Doppler concern
Reports mention abnormal Doppler flow, heart strain, hydrops, abnormal fluid around the baby, or worsening fetal condition.
FAQs
Frequently asked questions about TTTS laser surgery
What is TTTS?
TTTS is twin-to-twin transfusion syndrome. It occurs in monochorionic twin pregnancies when abnormal placental blood vessel connections create unequal blood flow between the two babies.
Which twin pregnancies are at risk?
TTTS occurs only in monochorionic twin pregnancies, where both babies share one placenta. Determining chorionicity early is very important in twin pregnancy care.
What is laser surgery for TTTS?
Fetoscopic laser surgery is a fetal therapy procedure where abnormal placental vascular connections between the twins are identified and sealed using laser energy. It is considered only in selected cases after detailed staging.
Does every TTTS pregnancy need laser?
No. Some cases need close surveillance, while selected progressive or advanced cases may require fetal therapy. The decision depends on stage, gestational age, fetal condition, Dopplers, cervix and counselling.
Can Mayflower help if laser treatment is needed outside Nagpur?
Yes. Mayflower can help with TTTS diagnosis, staging, scan documentation, counselling and referral coordination to an appropriate fetal therapy team when laser therapy is required.
What reports should I bring for TTTS consultation?
Bring all previous ultrasound reports and images, twin pregnancy chorionicity report, anomaly scan report, Doppler reports, blood tests, obstetric notes and any referral letter from your treating doctor.
Is TTTS an emergency?
Suspected TTTS should be assessed promptly by a fetal medicine specialist. Some cases are stable and monitored closely, while others need urgent referral for fetal therapy depending on stage and fetal condition.
Can laser surgery guarantee both babies will be fine?
No. Laser therapy can improve chances in selected cases, but it cannot guarantee survival or normal outcome. Parents are counselled about expected benefits, risks and limitations before any decision.
