What it is: A placenta that implants too firmly and deeply into the uterine wall. Similar conditions include placenta increta and percreta, in which the placenta breaks through the uterine wall, sometimes hitting nearby organs.
Health dangers: Premature birth or serious bleeding after vaginal delivery.
Risk factors: Having had placenta previa or previous uterine surgery.
Signs and symptoms: Vaginal bleeding during the third trimester.
Diagnosis and treatment: A hospital exam and an ultrasound, followed by a c-section and surgical removal of the placenta. Sometimes a hysterectomy is necessary. In some cases, other surgical procedures can save the uterus.
It's likely that you will not develop any placental problems. But it's best to take any steps you can to reduce your risk. And remember to call your doctor if you experience vaginal bleeding. Prompt care can lessen the chance of serious complications for you and your baby.
