Bedside Ultrasonography for Emergent Patients in the Diagnosis of Vasa Previa and Umbilical Cord Prolapse / 中国医学影像学杂志

ABSTRACT

Purpose To investigate the value of bedside ultrasonography for emergent patients in the diagnosis of vasa previa and umbilical cord prolapse. Materials and Methods The bedside ultrasonography data of 12 emergent cases of vasa previa and 18 emergent cases of umbilical cord prolapse were retrospectively analyzed for detection rate. Results Nine out of 12 emergent patients with vasa previa were detected by bedside ultrasonography;2 were misdiagnosed as umbilical cord prolapsed;and 1 patient who had missed diagnosis suffered fetal demise during vaginal labour. Fifteen out of 18 emergent patients with umbilical cord prolapse were detected by bedside ultrasonography;2 were misdiagnosed as vasa previa; and 1 missed diagnosis (no death case was reported). The detection rates for both groups of patients had no significant difference (P>0.05). Conclusion Bedside ultrasonography for emergent patients can visualize the traveling of vasa previa and umbilical cord prolapse so as to promptly provide evidence for clinical diagnosis and reduce perinatal mortality.
