SANTO DOMINGO, Domincan Republic ---An infant girl born with a second head bled to death Saturday after complex surgery (外科手术) to remove her partially formed twin , her parents and doctors said.

A medical team completed the 11- hour operation Friday night and said 8-week-old Rebecca Martinez died seven hours later. Doctors had warned after the surgery that the girl would be at great risk of death.

“ We knew this was a very risky surgery , and now we accept what God has decided , “ Rebecca’s father , 29-year-old Frankin Martinez, said at a news conference with his wife. “ Rebecca is no longer with us physically , but no one will forget her.”

Martinez said the family would bury Rebecca in a private funeral later in the day.

The girl lost a lot of blood in the operation, which apparently ( 明显地) caused her to suffer a heart attack , said Dr. Jorge Lazareff , the lead surgeon . Friends and family donated (捐赠) almost 4 gallons of blood for surgeons to use Rebeca’s operation

“This was not a failure or an error ,” Lazareff said . “ When we left here last night the girl was in stable condition. At some point in the middle of the night , she started to bleed.”

Rebecca was born Dec. 10 with the undeveloped head of her twin, an exteremely rare condition known as craniopagus parasticus . Rebecca was the eighth documented case in the world of craniopagus parasiticus, doctors said.

All the other infants documented to have had the condition died before birth , making Rebecca\s surgery the first known operation of its kind.

Without an operation , Rebecca would have barely been able to lift her head at 3 months old. Her doctors said the pressure from the second head would have prevented her brain from developing.

“ We always saw Rebecca without the extra part of her body, ”er father said after her death.

Rebecca was their third child-----along with a 4-year-old boy and a 1-year-old girl.
