Abstract

STUDY DESIGN: A prospective observational study. OBJECTIVE: To find out the
predictive values of an ultrasound based scoring system in diagnosis of morbidly adherent
placenta for high risk group. SETTING: Obstetrics and Gynecology Department, faculty
of medicine, south Valley University, Egypt. DURATION: From June 2017 to May
2018. PATIENTS AND METHDS: 63 full term pregnant women (>_37weeks of
gestation) with high risk of morbidly adherent placenta underwent elective cesarean
section. Placenta assessment by 2 D ultrasound based on ultrasound scoring system in
morbidly adherent placenta, these data were recorded for further comparison with
interaoperative data for degree of placental adherence. RESULTS: Incidence of MAP
was 20.6% (14.3% had a focal form and 6.3% had a complete form of accreta), p value
<0.001. As regarding to scoring system, 82.5 of cases had a low risk (< 5), 9.5% had a
moderate risk (6-7) and 7.93% had a high risk (8-12) of development of morbidly
adherent placenta with p value <0.0001. The sensitivity, specificity, positive and negative
predictive values of the US scoring system for morbidly adherent placenta were (92.3%,
94.1%, 87.453% and 98.2% respectively). CONCLUSIONS &
RECCOMMENDATIONS: Ultrasound based scoring system had a high predictive
values (sensitivity, specificity, positve and negative predictive values) in diagnosis of
morbidly adherent placenta for pregnant women have any risk factors for developing
MAP.
