Na vasa praevia, os vasos sanguíneos fetais que conectam a placenta e o cordão umbilical cruzam o orifício cervical interno, a entrada do canal de parto, abaixo do feto. Estes vasos são mais propensos a serem lesionados por instrumentação (p. ex., eletrodo no couro cabeludo, cateter de pressão intrauterina, exames vaginais) ou simplesmente devido às forças mecânicas normais do trabalho de parto, levando à perda grave de sangue fetal. | |||
