　第二篇 Brain-dead Mother Dies after Giving Birth　　A brain-dead woman who was kept alive for three months so she could deliver the　child she was carrying was removed from life support on Wednesday and died, a day after giving birth.
　　"This is obviously a bittersweet time for our family," Justin Tortes, the woman's brother-in-law, said in a statement.
Susan Tortes, a cancer-stricken, 26-year-old researcher at the National Institutes of Health, suffered a stroke in May after the melanoma (黑瘤) spread to her brain.
　　Her family decided to keep her alive to give her foetus (胎儿) a chance. It became a race between the foetus' development and the cancer that was destroying the woman's body.
　　Doctors said that Tortes' health was getting worse and that the risk of harm to the foetus finally outweighed the benefits of extending the pregnancy.
Tortes gave birth to a daughter by Caesarean section (剖腹产手术) on Tuesday at Virginia Hospital Center. The baby was two months premature and weighed about a kilogram. She was in the newborn intensive care unit.
　　Dr Donna Tilden-Archer, the hospital's director of neonatology (新生儿学), described the child as "very vigorous." She said the baby had responded when she received stimulation, indicating she was healthy.
　　Doctors removed Tortes from life support early Wednesday with the consent of her　husband, Jason Tortes, after she received the final sacrament (圣礼) of the Roman　Catholic Church.
　　"We thank all of those who prayed and provided support for Susan, the baby and our　family," Jason Tortes said in a statement. "We especially thank God for giving us little　Susan. My wife's courage will never be forgotten."
English-language medical literature contains at least 11 cases since 1979 of
irreversibly brain-damaged women whose lives were prolonged for the benefit of the　developing foetus, according to the University of Connecticut Health Center.
　　Dr Christopher McManus, who coordinated care for Susan Tortes, put the infant's　chances of developing cancer at less than 25 per cent. He said 19 women who have had　the same aggressive form of melanoma as Tortes have given birth, and five of their　babies became ill with the disease.Susan Torres died soon after A．she suffered a strok
