Prolapsed umbilical cord is a rare condition that occurs in 1% of pregnancies. It’s a situation when the umbilical cord comes out of the uterus with or before the presenting part of the fetus. Pressure on the cord from the fetus will cause cord compression that compromises blood flow to the fetus. This is common in women who have had rupture of their amniotic sac. Prolapsed umbilical cord is an emergency during pregnancy and labor because of the possibility of fetal death and other complications.
Risk factors include abnormal fetal lie, too much amniotic fluid, or a premature or small fetus.
