Diagnosis and Management of Cesarean Scar Pregnancy and Placenta Accreta Spectrum

With an increased cesarean delivery rate, the incidence of abnormal placentation is steadily rising, and it is estimated to be around 1.7 per 1000 pregnancies for cesarean scar pregnancy and 1 per 500 pregnancies for placenta accreta spectrum disorder. Current evidence considers cesarean scar pregnancy and placenta accreta spectrum as being the same condition, with different aspects, of the same spectrum, having higher risks with advancing gestation. We present 7 cases, diagnosed and managed in our hospital, at different gestational ages. Early diagnosis is essential for appropriate counseling and subsequent management, and an ultrasound examination is the reference standard for diagnosis. Screening for an abnormally implanted placenta in the first trimester of pregnancy might improve the perinatal outcome and reduce maternal morbidity and mortality.
