A rare example of the partial rupture of the umbilical vein resulting in a cord haematoma is reported. CTG alterations made possible to anticipate the deterioration of the foetal condition and a healthy infant was delivered by emergency caesarean section. Cross sections of the umbilical cord revealed the lack of one of the umbilical arteries and the haematoma having interfered with the foetal circulation.
