Can placenta previa lead to placenta precreta?

Answer 1

No. that's like comparing Apples to Oranges. Placenta Previa is when the Placentation grows across the Cervical Os, blocking baby's Natural Way Out. CS is the Usual Mode of delivery in these, otherwise Mama can Bleed, possibly to death. Placenta PERCRETA, is one of the three 'Creta Sisters, all terms used to describe a placenta that Invades the Uterine wall. These are, sorted by Level of Severity, Placenta Accreta, in which the placental Villi are penetrating too deeply into the Uterine wall, causing issues with hemmorhage post-Delivery, Placenta Increta, in which the placentation penetrates through the Uterine wall & into it's Muscle Layer, and finally Placenta Percreta, in which the placentation grows all they way through the uterus, possibly attaching to other organs. If you've got Simple Previa & it's known about in advance of Delivery, your birth mode might have to change to a Safety Driven CS. (it makes for a Right Nasty Surprise, if it isn't found in Advance of Delivery, possibly a Life Threatening one, so go get that Sono done). If it's one of the 'Creta Sisters, you need to see a Maternal Fetal Medicine specialist or a Perinatologist to keep track of the placentation as it develops & a plan of Surgical Delivery developed, with VB completely off the table. Hysterectomy at time of Delivery can be a Real possibility especially if it's one of those last 2 'Creta Sisters there. Not to frighten anybody, but if it's ANY of the 'Cretas, find an excellent physician & Surgeon to handle the Complex delivery required.

ALL these described conditions can potentially Kill Everybody directly involved with gestation (Mom & Baby(ies). NO LABOR or FULL CONTRACTION ACTIVITY, Mom or baby can bleed out if the placentation detaches, or is Shredded by baby in the case of Previa. Previa is Not associated in any way with the 'Creta sisters & cannot 'evolve' or 'worsen' into them.
