Introduction: An increased risk of placenta accreta and placenta percreta is associated with patients having had previous caesarean deliveries or placenta previa; such conditions have been increasing of late. Prenatal detection may be helpful in reducing maternal morbidity and mortality.
Objective: evaluating the usefulness of ultrasound (US) and magnetic resonance (MR) for prenatal detection of abnormal placental separation.
Methodology: this was a prospective study which included 11 patients in the third trimester of pregnancy having a history of previou scaesarean and placenta previa. Transabdominal and transvaginal US, colour Doppler and MR were thus performed, seeking signs of placenta accreta; these were compared to histopathological findings and data from when birth was given.
Results: US and MR had 70% sensitivity (95% CI 35.4-91.9) whilst colour Doppler had 90% sensitivity (95%CI 54.1-99.5).
Conclusions: US and colour Doppler US might be useful, highly sensitive techniques for detecting abnormal adherence of the placenta in patients having a history of placenta previa and previous caesarean deliveries. Further studies are required for confirming their diagnostic validity.
