What is a potential outcome for the fetus if vasa previa is not managed appropriately during labor?

Vasa previa occurs when fetal blood vessels run across or near the internal cervical os, which can lead to significant risks during labor, particularly if the membranes rupture. If vasa previa is not diagnosed and managed appropriately, the exposed vessels can tear during labor, leading to rapid fetal hemorrhage. This can result in catastrophic outcomes, including stillbirth, especially if the fetal distress is not recognized and managed promptly.

The risk of stillbirth is particularly pronounced because the fetus may not survive the sudden loss of blood supply or if emergency interventions are delayed. Therefore, close monitoring and timely intervention are crucial in cases of vasa previa to prevent such tragic outcomes.
