Once the diagnosis is done, it is important to classify the sIUGR in three different types according to the Doppler in the umbilical artery UA of the small baby. A proposito de un caso.

The ultrasound findings that worsen the prognosis of a pregnancy complicated with sIUGR are the discrepancy in the EFW between the twins, Doppler of the umbilical artery and ductus venosus of the restricted foetus along with oligohydramnios, gestational age at oligohidramnips moment of the surgery and cervical length 7.
