Seven cases of ultrasound diagnosis of velamentous insertion (VCI) of the umbilical cord at singleton pregnancies on 21–34 weeks of gestation are presented. The ultrasound picture two of the VIC types is presented: fixed in 5 cases and free in 2 cases. In one case the VCI was in the lower third of the uterus and the wound has been diagnosed the vasa previa. In other cases, the VCI was in middle third of the uterus. In all cases delivery was at 37–39.1 weeks of gestation. In 4 cases Cesarean sections were performed. In two of the VCI cases elective Ce sarean sections were performed for the following indications: previous Cesarean section and vasa previa. VCI can reliably be detected prenatally by gray-scale and color Doppler ultrasound. For fixed VCI located in the middle-upper of the uterus, no change in standard obstetrical management seems to be required.

Abstract Objectives Evaluate ultrasound diagnostic accuracy, maternal−fetal characteristics and outcomes in case of vasa previa diagnosed antenatally, postnatally or with spontaneous resolution before delivery. Methods Monocentric retrospective study enrolling women with antenatal or postnatal diagnosis of vasa previa at Sant’Anna Hospital in Turin from 2007 to 2018. Vasa previa were defined as fetal vessels that lay 2 cm within the uterine internal os using 2D and Color Doppler transvaginal ultrasound. Diagnosis was confirmed at delivery and on histopathological exam. Vasa previa with spontaneous resolutions were defined as fetal vessels that migrate >2 cm from uterine internal os during scheduled ultrasound follow-ups in pregnancy. Results We enrolled 29 patients (incidence of 0.03%). Ultrasound antenatally diagnosed 25 vasa previa (five had a spontaneous resolution) while four were diagnosed postnatally, with an overall sensitivity of 96.2%, specificity of 100%, positive predictive value of 96.2%, and negative predictive value of 100%. Early gestational age at diagnosis is significally associate with spontaneously resolution (p 0.023; aOR 1.63; 95% IC 1.18–2.89). Nearly 93% of our patient had a risk factor for vasa previa: placenta previa at second trimester or low-lying placenta, bilobated placenta, succenturiate cotyledon, velametous cord insertion or assisted reproduction technologies. Conclusions Maternal and fetal outcomes in case of vasa previa antenatally diagnosed are significally improved. Our data support the evaluation of umbilical cord insertion during routine second trimester ultrasound and a targeted screening for vasa previa in women with risk factor: it allows identification of fetus at high risk, reducing fetal mortality in otherwise healthy newborns.

We present here a case of vasa previa in a multipara, diagnosed at the time of her late second trimester ultrasonogram. The patient subsequently underwent an elective cesarean section after 37 weeks gestation, giving birth to a healthy child with an uneventful post-partum, neonatal and infant course. At the time of cesarean section, the incision was gradually deepened in layers through the myometrium by utmost care allowing the amniotic sac to protrude through the uterine incision hereby avoiding laceration of the vasa previa and its branches. Fetal exsanguination and a need for blood transfusion as well as a possible adverse neonatal course were therefore avoided.
