Each suffers from heart disease and the pair weigh a total of 3.4 kilograms.

The surgery was conducted on Friday by a team of seven doctors and four other medical workers, led by the hospital’s Deputy Director Dao Trung Hieu.

The twins were released from the hospital Wednesday.

Hospital Director Tang Chi Thuong said Wednesday it was the most complicated conjoined twins surgery the hospital had ever conducted. He said the conjoined livers had made the procedure particularly complex.

The Children Hospital No. 1 is set to receive another pair of conjoined twins from the south-central province of Binh Thuan.

The babies were born by caesarean section around 3 p.m. Wednesday at An Phuoc General Hospital in Binh Thuan Province.

It was 24-year-old mother Nguyen Thi Dieu Hien’s first birth.

An Phuoc General Hospital Director Phan Ngoc Hung said the two female babies weighed a total of 3.3 kilograms and were born attached at the abdomen. But they shared no internal organs, he said.

The caesarean was conducted after 32 weeks of pregnancy when the mother showed signs of giving premature birth.
