In brief: Attached over cervix

Placenta previa is when the placenta attaches low inside the uterus, near theopening of the birth canal/cervix.
This can cause problems during the birth process because when the cervix starts dilating it could tear the blood vessels in the placenta, depriving the baby of blood and making mom lose too much blood. To be safe, many ob's recommend a c-section instead of vaginal birth.

In brief: Placenta problem

Placenta previa occurs when the placenta blocks the cervical os, the exit from the uterus.
Typically need c-section. Vaginal bleeding can be severe enough to require transfusion. If get previa after previous c-section, risk for accreta -placenta growing into uterine wall- increases for each past c/s. This may need c-section + hysterectomy, which can be very dangerous due to high blood loss.

In brief: High risk

Previa: Placenta overlies the cervix/birth canal.
Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.
