- Twin-To-Twin Transfusion Syndrome (TTTS)
- What?
- When twins share a placenta, and there is abnormal connecting blood vessels within it.
- Results in a higher blood volume in one twin than the other.
- This means that blood from one twin (donor) is transfused to the other (recipient).
- The recipient twin has too much blood, so the heart has to work extra hard. The donor twin has too little blood, so may suffer from anaemia.
- The donor twin may have a smaller amniotic sac, whilst the recipient may have a larger amniotic sac.
- Who?
- It effects twins who share a placenta.
- It effects 10-15% of monochorionic (sharing a placenta and outer membrane) pregnancies.
- Why?
- Want to study midwifery at university.
- Effects a significant number of pregnancies.
- Interested in problems that can occur in multiple pregnancies
- How?
- Diagnosis
- From as early as 12-14 weeks.
- Detected through ultrasound scans.
- Tell-tale signs include different sized babies, bladders or amniotic sacs.
- Treatment
- Amnioreduction
- Draining of excess amniotic fluid from the recipient twin.
- 44% success rate of having two babies 66% of producing one.
- Septostomy
- Creating a hole in the amniotic membrane between the babies, to allow the fluid levels to equalise.
- Laser Treatment
- Breaks the vessels causing the problem in the placenta.
- Only treatment that can effectively reverse the effects of TTTS.
- Selective Feticide
- The termination of one foetus so that the other may survive.
- Amnioreduction
