The twins were monochorionic diamniotic (MCDA) - which means they share a single placenta - and in the letter the trust states that it admits that abdominal pain in women expecting MCDA twins can be the first indication of the development of TTTS.
It was such a relief when the consultant said the TTTS had resolved itself - a C-section at 32 weeks was the last thing I wanted to happen.
TTTS is a severe complication of monochorionic twin pregnancies, with high perinatal loss and significant morbidity in surviving neonates (Rausen et al.
Some of the treatment options for TTTS include: amnioreduction, in which excess amniotic fluid is removed from the amniotic sac of the recipient twin throughout the pregnancy; monitoring of the pregnancy through routine ultrasound; or endoscopic laser surgery performed during pregnancy, in which a laser is used to seal off the placental blood vessels through which the twins are unequally sharing blood.
Although none of the 17 cases of MCDA-T were complicated by TTTS at the time of blood sampling, TTTS subsequently developed in 5 cases (TTTS group), but not in the remaining 12 cases (no-TTTS group).
In the days before ultrasound, by 24 weeks 90 per cent of babies with TTTS would miscarry, only a few would survive, and around half of those would be handicapped.
THE Twins and Multiple Births Association (Tamba) is launching an appeal to fund research into TTTS.
Up to 10 short "Keekisodes" will be released on the Keek platform on the TTTS channel where users can watch 36 second sneak peaks into the creation of the show prior to each full-length episode release, and exclusive bonus clips as companion content.
