What is the best delivery method for placenta previa Marginalis?

What is the main cause of placenta previa?
The greatest risk of placenta previa is too much bleeding (hemorrhage). Bleeding often happens as the lower part of the uterus thins during the third trimester of pregnancy. This causes the area of the placenta over the cervix to bleed. The risk of bleeding is higher if a lot of the placenta covers the cervix.
What are the three types of placenta previa?
Historically, there have been three defined types of placenta previa: complete, partial, and marginal. More recently, these definitions have been consolidated into two definitions: complete and marginal previa. A complete previa is defined as complete coverage of the cervical os by the placenta.
