An important risk factor for placenta accreta is placenta previa in the presence of a uterine scar. Placenta previa is an independent risk factor for placenta accreta. Additional reported risk factors for placenta accreta include maternal age and multiparity, other prior uterine surgery, prior uterine curettage, uterine irradiation, endometrial ablation, Asherman syndrome, uterine leiomyomata ...
Specifically, placenta accreta involves abnormal adherence of the placental trophoblast to the uterine myometrium. [54] Placenta accreta risk factors include placenta previa, abnormally elevated second-trimester AFP and free β-hCG levels, and advanced gestational parent age, specifically over the age of 35.
Abnormalities present within the spiral arteries lead to higher velocities in blood, in turn causes the maternal villi to shred. [5] Which trigger pro-coagulator molecules to be released into the blood stream causing action of the coagulator cascade, eventually leading to placental infarction. [ 5 ]

If a trisomic conception undergoes trisomic rescue in certain cells, including those that are destined to become the baby, then the remaining trisomy cells may be confined to the placenta. Several factors influence the pattern of normal and abnormal cells in the developing embryo. Reduced or improved replication rates of the trisomic cells ...
