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.
