umbilical cord prolapse
Umbilical cord prolapse is a situation where the umbilical cord protrudes into the cervical canal.
The estimated incidence is at ~ 0.2-0.5% of all pregnancies .
Recognized associations include
- multifetal pregnancy: twin gestation
- non cephalic/abnormal presentation(s)
- cord (funic) presentation
- breech presentation
- transverse presentation
- low birth-weight: less than 2500g at term
- spontaneous rupture of membranes
- long umbilical cord: >90 cm
May show herniation of the umbilical cord into the cervical canal/lower uterine segment . Color Doppler is useful at confirmation .
Treatment and prognosis
A cord prolapse is an obstetric emergency that in a viable fetus necessitates an expeditious delivery . Energetic intrapartum monitoring is often recommended in order that patients with occult prolapse or presentation of the umbilical cord be diagnosed early and treated promptly.
