central placenta previa

pla·cen·ta pre·vi·a cen·tra·lis

placenta previa in which the placenta entirely covers the internal os of the uterus.

central placenta previa

Etymology: Gk, kentron + L, placenta, flat cake, praevius, preceding
placenta previa in which the placenta is implanted in the lower segment of the uterus and completely covers the internal os of the uterine cervix. In labor, as the cervix dilates, the placenta is gradually separated from the underlying blood vessels in the uterine lining, causing bleeding that usually begins slowly, is painless, and progresses to hemorrhage that is life-threatening to the mother and the baby. Cesarean section is usually performed to save the mother and the baby. The condition may be discovered by ultrasound visualization before any bleeding occurs or by digital palpation in the normal course of prenatal care. Also called complete previa. See also placenta previa.
