In recent years, with the application of an abdominal artery balloon and the improvement of surgical techniques, efforts are made to preserve the uterus for patients PAS. the aim of the study To evaluate conservative surgical management of placenta accreta spectrum in Assiut University hospital regarding maternal and fetal outcomes.

Placenta accreta spectrum disorder (PAS) is a serious obstetric disorder that is characterized by low lying and deep penetration of the villi which are abnormally attached to the myometrium of the uterus. This obstructs its complete separation during the third stage of labor which induces continued bleeding and have potentially life- threatening for the mother. Most commonly, it is a consequence of a partial or complete absence of the compact and spongy layer known as the decidua basalis, and mis-development of the fibrinoid Nitabuch's layer which lies between the boundary zone of the thick endometrium and the cytotrophoblastic shell in the placenta.

Traditionally, caesarean hysterectomy at the time of delivery has been the preferred management strategy for placenta previa accreta. Not only does this approach preclude future fertility, but it is also a procedure synonymous with significant perioperative risks. For women who wish to conserve their reproductive function, other treatment options have been described.

Different methods have been employed to manage the PA, ranging from uterine conservation, which involves leaving the placenta in situ, to conventional hysterectomy. Classical cesarean sections (C- sections) prevent the excessive bleeding by leaving the adherent placenta in situ and by adopting strategic planning with a comprehensive analysis that aids the reduction in maternal morbidity and mortality rates.
