A velamentous cord insertion occurs when the umbilical cord’s Wharton jelly fails to reach the placenta, due to early placental atrophy around the insertion site, leaving a segment of unprotected vessels running through the thin membranes of the amniotic sac. This area of weakness exposes a threat to the well-being of the fetus through acute hemorrhage and both acute and chronic restriction of nutrition. With advances in technology, resolution capabilities of ultrasounds allow for antenatal diagnosis, when previously this was impossible. With this knowledge, considerations for screening and management of this pathology are essential when dealing with a rural population that has barriers to accessing health care.
