A surgeon at Mater Mothers’ Hospital in Brisbane has saved a tiny Nambour twin baby girl’s life after operating on her while she was still in her mum’s womb.

Nambour mum Ti Bridge spent Mother’s Day with her toddler son Lachlan and her miracle baby Chelsea by her side – a bitter-sweet day without Chelsea’s twin sister, Imogen. 

Imogen, who sadly passed away before birth, was Chelsea’s identical sister. They were diagnosed with rare twin-to-twin transfusion syndrome (TTTS), a life-threatening condition where both babies share one placenta.

In a bid to save both babies at just 18 weeks into Tia’s pregnancy, Mater Maternal Fetal Medicine’s Professor Sailesh Kumar performed a complex, minimally-invasive surgery known as Fetoscopic Laser Photocoagulation (FLP) – using a fetoscope to locate the abnormal blood vessel connections between the babies on the surface of the placenta and then sealing them using a laser. 

The laser ablation stops the abnormal blood transfusion between the twins, and can be curative.

Prof Kumar said that without FLP neither of the siblings would have survived. About 20 FLP surgeries are performed each year in Queensland, and it is a known risk that losing one or even both twins after laser surgery is possible.

“There are risks to the procedure including the possibility of demise of both babies. However, parents are always counselled that there is a more than 80 per cent chance that at least one twin will survive,” he said.

Tia, 30, said that almost four weeks after the surgery to save her twins, a scan revealed Imogen’s heart had stopped beating.

“I was shocked and devastated,” she said.

“I knew there was a higher chance they could both pass if I didn’t do the surgery, but how could someone go through so many bad things?”

Tia Bridge described Chelsea, now seven months, as her “miracle baby”.

“She was born at just 25 weeks’ gestation weighing 635g, but she is now tipping the scales at almost 5kg. She is a very strong girl and has defied the odds,” Tia said.

“She’s sassy and knows what she wants. I can remember when she was so tiny, she would fit in the palm of my husband Toby’s hand. Her skin was see-through and there was nothing to her.

“I was scared to see her like that, it was so overwhelming.

“Chelsea is the bravest person I have met. I love her to bits.”

Despite experiencing breathing difficulties and battling multiple setbacks, baby Chelsea is a happy and cheeky little girl. 

After more than four months receiving around-the-clock care in the Neonatal Critical Care Unit at Mater Mothers’ Hospital, Tia said she could not thank the medical, nursing and midwifery teams at Mater enough.

“The care we received was phenomenal. 

“We always wanted to give Lachlan a sibling, and when she smiles her whole face lights up,” she said.

“Mother’s Day will be a pretty significant day for me.”
