Baby in Amniotic Sac
Baby born inside amniotic sac is rare phenomenon.

A Greek doctor has captured the incredible moment a baby was born still inside its amniotic sac.

Obstetrician Dr Aris Tsigris was stunned when he realised that the child was still encased in the sac after delivering it via caesarean section in Athens.

He shared a picture of the rare phenomenon on Facebook.

The image shows the newly delivered baby huddled in the foetal position inside the giant bubble-like structure.

One commentator wrote: " In Sweden this is called the Hood of Victory and means you'll have good luck and a long life."

The amniotic sac is the bag of fluid inside the womb where the unborn baby develops and grows. It is also referred to as the 'membranes', because the sac is made of two membranes called the amnion and the chorion.

Typical during the early stages of labour, the amniotic sac breaks, commonly referred to as the mother's "water breaking".

Tsigris said incidences of the amniotic sac remaining intact were "ultra rare" and that he was left breathless by the delivery, news site Nine msn reports.

He said that there was no risk to the baby as it was still getting food from the placenta and starting to breathe on its own as soon as the sac broke.

In 2011, Jessica Alba's daughter Haven was born inside the amniotic sac.

The Hollywood actress said at the time: "The doctor had never seen anything like it before. He grabbed the nurse and said, 'Look at this.

"He was wearing basketball shorts and a T-shirt and said: 'Oh I have to get my scrubs on for this.' The sac burst on its own after she came out. It was a trip."
