P02.3 Newborn affected by placental transfusion syndromes

Name of the Condition

• Newborn affected by placental transfusion syndromes
• Also known as: Twin-to-twin transfusion syndrome (TTTS), Twin anemia-polycythemia sequence (TAPS)

Summary

• Newborn affected by placental transfusion syndromes refers to conditions where there is an abnormal blood transfer between twins sharing the placenta, potentially affecting their health.

Causes

• The condition arises from an imbalance in the blood flow between fetuses sharing a single placenta due to shared placental vessels.

Risk Factors

• Twin or multiple pregnancies, especially those sharing a single placenta (monochorionic twins).
• Advanced maternal age.

Symptoms

• Babies may present with anemia or polycythemia (excess red blood cells), noticeable size difference between twins, or heart complications.

Diagnosis

• Prenatal ultrasound to monitor blood flow between the twins.
• Doppler studies to evaluate blood vessel connections.

Treatment Options

• Fetoscopic laser surgery to seal off connecting blood vessels between the twins.
• Amniocentesis for fluid balance management.
• Blood transfusions for anemia or blood dilution for polycythemia.

Prognosis and Follow-Up

• Prognosis varies; improved with early diagnosis and intervention.
• Requires regular follow-up with pediatricians and specialists to monitor development.

Complications

• Without treatment, can lead to heart failure, neurological damage, or stillbirth.
• Long-term developmental challenges due to oxygen supply issues during pregnancy.

Lifestyle & Prevention

• No definitive preventive measures due to its occurrence in utero.
• Regular prenatal check-ups for early detection in high-risk pregnancies.

When to Seek Professional Help

• Expectant parents with twin or multiple pregnancies should seek immediate medical evaluation if advised of uneven growth or fluid levels in twins during ultrasounds.

Tips for Medical Coders

• Ensure accurate documentation of the type of transfusion syndrome to apply correct coding.
• Be vigilant about capturing the condition's impact on each newborn if twins/multiples are involved.
• Avoid common errors like misclassifying other fetal conditions or non-transfusion-related complications.
