Two Italian girls of Romanian descent, three-year-old Anastasia and Tatiana Dogaru, were born connected at the head. Such twins are very rare occurring in about 1 in 2.5 million births. The top of Tatiana's head is attached to the back of Anastasia's.

They have been living in Dallas for the last two years with their parents and a six-year old sister where they were brought for separation surgery evaluation. Their living expenses and medical treatments have been funded by the World Craniofacial Foundation ever since they arrived to Dallas.

Their surgery is to take place in April, at the Babies & Children's Hospital in Cleveland, Ohio where a team of doctors will work on their separation.
The girls share numerous blood vessels and Anastasia has no kidney function and is dependant on her sister’s kidneys. Their blood vessels will be separated in four stages and Anastasia will need dialysis right after the surgery. A few months after they recover, Anastasia will have to undergo a kidney transplant, donated by one of her parents.

Tatiana's kidneys are clearing both girls' blood streams but her venous drainage is not functioning so well. After the separation, the doctors will do their best to make Tatiana's venous drainage begins operating as it should. Otherwise, she may not survive.

The girls will start with various tests at the end of April in order to prepare for the procedure. Doctors say that they share only a small portion of brain matter. Before they are finally separated, the girls will have skin expanders placed in their heads so there would be enough skin to cover their brains once they are separated.

Once the girls are medically stable, the doctors will begin reconstruction of their skull by placing a framework of demineralised bone under the skin.
The separation procedure is very dangerous and carries many risks including brain damage, stroke or a deadly amount of blood loss but the girls wouldn’t make it without one. Their conjoined condition would only bring further medical problems.
