    Abstract
  • Objective To discuss the clinical value and significance of ultrasonography for fetal umbilical vasa previa. Methods The doppler color sonographic features of 24 pregnant women diagnosed as fetal umbilical vasa previa after delivery in the obstetrics department of our hospital from January 2014 to December 2017 and fetal outcomes were reviewed. Results Among 8000 pregnant women hospitalized at that time, there were 24 vasa previa cases (0.300%), wherein 20 cases were correctly diagnosed by the color Doppler ultrasound (83.33%) and one missed diagnosis case (4.17%) and 3 misdiagnosis cases, including 2 cases of umbilical cord presentation and one case of cord prolapse. Among the 24 vasa previa cases, there were 14 cases of velamentous insertion of umbilical cord, 5 cases of accessory placenta, 4 cases of placenta bipartita and one case of marginal insertion of umbilical cord. All vasa previa cases received Cesarean section, and 28 infants survived while 6 infants dead. All 24 subjects discharged without complications. Conclusion Prenatal ultrasound examination can visualize the traveling of vasa previa and determine the orientation relationship between cord vessels and cervix internal ora. It has higher diagnosis accuracy on the vasa previa of umbilical cord, thus the first choice in screening and examination of vasa previa, so as to reduce the fetal death rate in clinical practice.
