'''Increased cord length''' (>80cm) has been associated with '''excessive cord torsion''' which can cause twisting of the umbilical blood vessels. This twisting causes '''increased resistance to blood flow''' in both directions and '''poor placental perfusion''' leads to '''foetal death''' and abortion of the autolysed foetus. | '''Increased cord length''' (>80cm) has been associated with '''excessive cord torsion''' which can cause twisting of the umbilical blood vessels.
