RESUMEN
The case of a pregnant patient who had a massive intracraneal haemorrhage at 18 weeks of gestation is presented. Patient's neurological damage evolved to brain death, but the fetus continued in good condition. The decision of withdrawing life support or to continue supporting the mother's life to allow fetal development aroused difficult ethical questions, both to relatives and professionals. This is an exceptional situation of a heart beating cadaver and a non viable fetus whose life depends on the continuation of treatments that are considered as experimental. A good decision should be based on the respect to a body in brain death, the fetal right to life, family's wishes and values, the use of experimental treatments, and the rational use of a public hospital's resources. The conclusion was that the continuation of life support treatments was not an ethical obligation. Withdrawing life support to allow fetal death in this case means foregoing an experimental treatment and to respect family's autonomy and the right of the patient's death with dignity. Similar cases need to be discussed with a multidisciplinary analysis in their own particularity
