O43.022 Fetus-to-fetus placental transfusion syndrome, second trimester
ICD10CM code
ICD10CM
Name of the Condition
Fetus-to-Fetus Placental Transfusion Syndrome, also known as Twin-to-Twin Transfusion Syndrome (TTTS).
Summary
Fetus-to-Fetus placental transfusion syndrome is a prenatal condition affecting identical twins who share a placenta. It involves an imbalanced blood flow between the twins, resulting in one twin receiving too much blood and the other too little. This can cause serious complications if not treated.
Causes
The condition is caused by abnormal blood vessel connections in the shared placenta of monochorionic twin pregnancies, leading to unequal blood distribution.
Risk Factors
Occurs exclusively in monochorionic-diamniotic twin pregnancies where the twins share a single placenta.
Higher risk in pregnancies where twins develop from a single fertilized egg.
Symptoms
Symptoms are not experienced directly but may be detected via ultrasound showing differences in amniotic fluid levels or growth discrepancies between twins.
Diagnosis
Typically diagnosed through prenatal ultrasound, evaluating amniotic fluid levels, size discrepancies, bladder size, and blood flow patterns between the twins.
Treatment Options
Fetoscopic laser surgery to seal abnormal blood vessels in the placenta.
Amnioreduction to decrease excess amniotic fluid, alleviating pressure.
Serial amniocentesis in specific cases to manage fluid balance.
Prognosis and Follow-Up
Prognosis depends on the severity and timely management. Early diagnosis and treatment improve outcomes significantly.
Regular monitoring through ultrasounds is key to managing the condition and ensuring the health of both twins.
Complications
Without treatment, it can lead to heart failure in the donor twin, high blood pressure in the recipient twin, and even fetal demise for one or both twins.
Lifestyle & Prevention
While the condition cannot be prevented due to its nature, early prenatal care and regular monitoring can help in early detection and management.
When to Seek Professional Help
Immediate medical attention is advised if routine ultrasounds indicate any abnormalities regarding fluid levels or growth patterns in twin pregnancies.
