placenta percreta
Pronunciation: pla-SEN-ta per-KREE-ta
Most severe form of abnormal placental attachment where placental tissue invades through the uterine wall into adjacent organs.
Full Definition
Placenta percreta represents the most severe form of placenta accreta spectrum disorder, where placental villi penetrate completely through the uterine wall and may invade adjacent structures such as the bladder, bowel, or pelvic sidewalls. This condition poses extreme risks including massive hemorrhage, need for hysterectomy, and potential damage to surrounding organs. Management typically requires multidisciplinary planning with maternal-fetal medicine specialists, surgeons, anesthesiologists, and blood bank coordination. The condition is often diagnosed through advanced imaging including MRI and is associated with previous cesarean deliveries and placenta previa.
Usage
Usage note: Part of the placenta accreta spectrum. Distinguish carefully from accreta and increta forms.
