Abstract
Placenta accreta has a high potential for hysterectomy,
with a maternal death rate reported at 7%. Morbidly adherent
placenta may lead to massive obstetric haemorrhage resulting in
complications such as disseminated intravascular coagulopathy,
need for hysterectomy, injury of urinary tract and other viscera,
adult respiratory distress syndrome, renal failure and even death
However, antenatal diagnosis is the single most
important factor in improving the outcome in MAP, via high
degree of clinical suspicion along with ultrasound and MRI.
In this study, MRI was found to have a greater
diagnostic accuracy of 86.2 %in diagnosis of placenta accreta in
comparison with Doppler US which has a diagnostic accuracy
of 74.1%.
In this study, the most common ultrasound features in
predicting placenta accreta were the presence of placental
lacunae, the loss of retro-placental sonolucent zone, The most
dominant color Doppler finding in the current study was the
presence of increased amount of blood vessels and turbulent
blood flow, with 85.4% sensitivity, 47.1% specificity, both
PPV and NPV were 79.5% and 57.1%, respectively, with
diagnostic accuracy 74.1%. In this study, the most common MRI features in
predicting placenta accreta were the presence of uterine bulge
and heterogenous signal intensity within the placenta with
97.6% sensitivity, 58.8% specificity, both PPV and NPV were
85.1% and 90.9%,.
