A male new born was obtained without hearth rate or vitality, Apgar scale 0-0, weight 2800 grams, who presented an umbilical cord rupture 3 centimeters from its abdominal insertion, no where the fetal blood vessels are unprotected. It is necessary an adequate prenatal care, diagnosis and accurate management, to avoid the mortality by this rare clinical entity.
