摘要: We report a case of umbilical cord complication causing, fetal hypoxemia and acidemia. At 30 weeks gestation, the patient was referred because slightly increased amniotic fluid volume non-reactive cardiotocogram. Biometry appropriate for gestational age. Umbilical artery aortic Doppler findings were normal, whereas diastolic blood flow velocities in middle cerebral ductus venosus showed severely abnormal velocity waveforms with reversal during atrial contraction. Since other reasons could be excluded, careful examination performed. Traction hypercoiled due to its course around neck shoulders suspected. Cesarean section confirmed sonographic gases revealed This indicates that investigation venous may also help identify jeopardy than placental vascular resistance.
