Placenta accreta spectrum (PAS) represents the spectrum of clinical conditions when part or whole of the placenta becomes abnormally adherent or invades the myometrium . Over the last 40 years, caesarean delivery rates around the world have risen from less than 10% to over 30%, and almost simultaneously a 10-fold increase in the incidence of PAS . PAS is one of the most dangerous conditions of the pregnancy as it is significantly associated with maternal morbidity and mortality .~Ultrasound imaging is the most commonly used technique to diagnose PAS disorders prenatally. There is also wide variation globally on the management of PAS disorders, with some centres opting for a radical approach, whereas others have proposed a range of conservative approaches .~The conservative approaches include one-step conservative surgery, leaving the placenta in situ, the Triple-P procedure, and transverse B-Lynch suture . Recently, Women's health hospital has adopted a new approach for conservative management of most cases of PAS, including wedge resection of the myometrium over the adherent part of the placenta, or a staged-approach following delivery of the fetus starting with meticulous dissection of the urinary bladder form the lower uterine segment, then bilateral uterine artery ligation at a level below the apparent placenta-myometrial bulge, followed by removal of the placenta, after which a catheter is inserted in the cervix and the placental pouch is closed .
