When Jack Alexander and his partner Laura went for an early 16‑week scan they were overjoyed to learn they were expecting identical twin girls. That joy turned to urgent anxiety when clinicians identified signs of twin‑to‑twin transfusion syndrome (TTTS), a condition in which abnormal placental blood‑vessel connections can shunt blood and fluid from one twin to the other. “It’s devastating knowing that it could be 50/50. I’m just trying to be positive for my partner as she is very lost at the moment,” Jack told the Daily Mail as the couple came to terms with the diagnosis. (Daily Mail report)

Faced with stark choices, the couple were referred to a specialist fetal medicine centre at St George’s Hospital in London for assessment and possible fetoscopic laser surgery — a referral that turns a routine appointment into a six‑hour round trip from their home in Corfe Mullen, Dorset and into repeated stays away from their older children. Jack said the pair have launched a GoFundMe to cover travel and accommodation costs while Laura undergoes frequent monitoring and, if necessary, treatment. “We have to travel all the way up, and if she does have this laser treatment, she’s going to have to stay up there for a few days, recover, and see how she is,” he told the paper.

TTTS is uncommon but serious. Charity and clinical guidance note the condition affects roughly 10–15% of identical (monochorionic) twin pregnancies and arises from unbalanced blood flow through placental vessels, producing an often dramatic fluid imbalance between the two sacs. Typical warning signs include one twin with excessive amniotic fluid and the other with too little, together with discordant growth or absent bladder filling in the smaller twin. Twins Trust and clinical consensus documents underline that rapid referral to a specialist centre is essential for surveillance and management. (Twins Trust; 2011 clinical consensus)

The main definitive treatment for moderate and advanced TTTS is fetoscopic laser ablation, usually performed by specialist fetal medicine teams at tertiary centres. In that procedure a fine fibre‑optic fetoscope is passed through the mother’s abdomen into the uterus so the surgeon can visualise and coagulate the abnormal placental vessel connections with a laser; amnioreduction may follow to normalise fluid volumes. Centres such as St George’s and specialist units in the United States describe the operation as minimally invasive and typically short, but requiring experienced multidisciplinary care and close follow‑up. The Trust at St George’s also operates a national registry and co‑ordinates referrals for complex multiple pregnancies. (St George’s NHS Trust; UCSF Fetal Treatment Centre; Twins Trust)

How successful the operation is depends on disease stage at intervention and centre experience. Large reviews and centre series show that survival of at least one twin after laser therapy generally exceeds 85% in earlier stages, while dual survival figures are variable: some specialist centres report dual‑survival rates around 60–75% for less advanced disease, and systematic reviews find higher dual survival in stage‑stratified cohorts and lower rates in more advanced TTTS. Clinical teams therefore counsel parents with conditional, stage‑specific probabilities rather than certainties. “The laser surgery is not a risk‑free procedure. It can trigger early birth or a miscarriage,” Professor Asma Khalil of St George’s told the Daily Mail, emphasising the need for continued monitoring after the operation.

Beyond survival statistics, clinicians and charities emphasise the psychological strain on families. Twins Trust and specialist centres offer information, peer support and practical guidance for parents navigating surveillance, urgent decision‑making and the prospect of preterm delivery. St George’s describes its Twins Trust Centre as a hub for clinical care, research and family support, and clinicians warn that parents often need emotional as well as medical assistance during and after treatment.

Public‑facing accounts have helped raise awareness of the condition. Earlier this year the singer Jesy Nelson publicly described an emergency intervention after her monochorionic twin pregnancy developed complications consistent with pre‑TTTS; she later gave updates that both babies were safe. High‑profile cases do not change the underlying clinical decision‑making, but they can help families locate specialist centres and charities and reduce the sense of isolation.

For Jack and Laura the immediate practical challenge remains arranging frequent trips to a specialist centre while caring for three older children and weighing the uncertain risks and benefits of laser therapy. The couple say they are fighting for the best possible outcome for both girls and are seeking financial help to meet the logistical burden while they navigate a clinical pathway that, specialists stress, is best managed in centres with TTTS expertise. Families facing a similar diagnosis are advised to seek prompt referral to a designated fetal medicine service and to contact Twins Trust and the appropriate tertiary centre for information and support.
