This study comprised 84 people who had been diagnosed with PAS condition. Patients were divided into three groups based on the management strategy that was employed: Group B (n = 40) had a cesarean section (CS) with cervical inversion and ligation of both uterine arteries; group C (n = 16) had a cesarean hysterectomy with the placenta left in place. The questionnaire was pretested, corrected and finalized. Data were collected by face-to-face interview and analyzed by appropriate computer based programmed software Statistical Package for the Social Sciences (SPSS), version 24.

About 16 (57.1%), 18 (64.3%) and 3 (18.8%) of them had a parity ≥ 3 in Group-A, Group-B and Group-C respectively. 17 (60.7%) in Group-A and 15 (37.7%) in Group-B of them had ≥2 previous CSs. 9 (31.1%), 11 (27.5%) and 5 (31.3%) of them had previous history of placenta previa in Group-A, Group-B and Group-C respectively. About 8 (25.0%) patients in group-A, 12 (28.6%) in group-B and 6 (55.0%) in group-C had the history of previous ...
