A Remarkable Occurrence: Baby Girl Born Enveloped in her Amniotic Sac, Defying the Odds of a One-in-80,000 Event

Incredible images have captured an extremely rare case of a baby being born while still inside their amniotic sac.

The birth took place at Hospital Evangelico in Ipora, Goias State, west-central Brazil on 10th October.

The heavily pregnant Naiara Santos needed a caesarean to deliver her twin daughters.

This the incredible moment little Isabella emerged into the world still inside her amitotic sac

While the first twin Rafaella was born normally, doctors were stunned when her sister Isabella emerged still inside her amniotic sac.

Known as an en caul birth, this phenomenon occurs in fewer than one in 80,000 deliveries.

This is because the fluid-filled membrane usually breaks as a mother is about to go into labour – a process colloquially known as the ‘waters breaking’.

Obstetrician Leandra Campos reportedly told local media: ‘It’s very magical.

‘Because before we burst the sac, the baby was right there sleeping, without needing to breathe, receiving everything through the umbilical cord.’

She added: ‘I’ve done other en caul births, but this was the first time with the baby in the breech position. These births are rare.

‘You need to have a lot of technique for them to come out still inside the sac. And this is how we can see how they sit inside the belly before they are born.’

Ms Santos and daughters have stayed in the hospital since the birth but were expected to be discharged soon.

During a pregnancy with twins each baby can have their own individual amniotic sac.

Numerous myths and beliefs surround en caul births, which are also called mermaid or veiled births.

One is that babies are somehow destined for greatness or will be lucky in life — with many historical figures said to have been born in this fashion.

Another bogus belief is that those born en caul can never drown.

The amniotic sac is the jelly-like bag of fluid that encases the foetus. It’s made of two membranes, the amnion and the chorion.

Though thin, it is robust, holding an increasing amount of fluid throughout gestation, including the foetus’s urine.

In an ‘en caul’ birth, the main priority is to break the sac to allow the baby to breathe, since as they may no longer have oxygen supplied from being inside their mother.
