Understanding Twin-to-Twin Transfusion Syndrome (TTTS) and How It’s Treated in the Womb
By MediScan Systems | Updated June 2025

Twin pregnancies are a joyful and exciting journey — but when both babies share a placenta, careful monitoring becomes critical. One but serious complication is Twin-to-Twin Transfusion Syndrome (TTTS), a condition that affects monochorionic (identical) twin pregnancies.

At MediScan Systems, we specialize in early detection, laser therapy, and fetal monitoring to manage TTTS effectively. Here’s what every parent of twins needs to know

What Is Twin-to-Twin Transfusion Syndrome?

TTTS occurs when identical twins share a single placenta and develop abnormal blood vessel connections. These connections cause unbalanced blood flow between the twins:

  • One twin becomes the donor, losing too much blood and amniotic fluid.
  • The other twin becomes the recipient, receiving too much blood, risking heart failure.

Left untreated, TTTS can lead to:

  • Premature birth
  • Organ failure
  • Neurological injury
  • Fetal demise (in one or both twins)

It typically appears between 16 and 26 weeks of pregnancy but can occur earlier or later.

How Is TTTS Diagnosed?

MediScan uses high-resolution ultrasound and Doppler scans to detect:

  • Amniotic fluid volume discrepancies
  • Fetal bladder visibility
  • Growth discordance
  • Abnormal blood flow between twins

We classify TTTS into Quintero stages (I–V) to guide treatment.

Early detection is crucial. Regular scans are recommended for all monochorionic pregnancies starting from 12–14 weeks.

Treatment Options for TTTS at MediScan Systems

1. Fetoscopic Laser Photocoagulation (FLP)

This is the gold standard treatment for TTTS. A small camera (fetoscope) is inserted into the uterus, and a laser is used to seal the abnormal vascular connections in the placenta.

Performed under local or regional anesthesia, FLP is minimally invasive and typically done between 16 and 26 weeks.

2. Amnioreduction

In mild cases or when laser is not immediately possible, excess amniotic fluid is removed via a fine needle. This can relieve pressure and delay disease progression.

Often used as a supportive therapy or pre-laser intervention

3. Ongoing Monitoring

Post-treatment, MediScan conducts frequent scans to monitor:

  • Fetal growth
  • Amniotic fluid levels
  • Cardiac function
  • Doppler blood flow

Our Twins Unit ensures continuous, specialized care tailored for high-risk multiple pregnancies.
