The study evaluates a proposed ultrasound checklist for detecting placenta accreta spectrum (PAS) in patients with a high likelihood of the condition, aiming to see how effective it is in identifying confirmed PAS cases.
Conducted over five years, the research included patients who had ultrasound assessments for PAS suspicion, with diagnoses confirmed through surgical and histopathological findings.
Results showed an 80.7% PAS diagnosis among participants, with the third-trimester ultrasound displaying a sensitivity of 84% and specificity of 73%, highlighting key ultrasound features—abnormal placental lacunae and myometrial thinning—as strongly associated with PAS.
