Pathophysiology of Accreta

This chapter reviews the pathophysiology of Placenta accreta (PA) and evaluates the possible mechanisms leading to an abnormally invasion of the uterine wall by placental tissue. Ultrasound imaging and magnetic resonance imaging are commonly used for the prenatal diagnosis of PA. PA has been subdivided into total, partial, or focal, depending on the amount of placental tissue involved. On the anterior uterine wall of the uterine corpus, the muscle fibers from each side crisscross diagonally with those of the opposite side but run in a predominantly transverse direction. The main anatomical impact of a uterine surgical procedure such as a caesarean section or a myomectomy will be at the level of smooth muscular layers of the myometrium. Myofiber disarray, tissue edema, inflammation, and elastosis have all been observed in uterine wound healing after surgery. A caesarean scar pregnancy is the implantation of clinically detectable pregnancy into a scar.
