Diagnosis of PP was made by ultrasonographic examination (Voluson 730 scanner, GE Medical systems, Milwaukee, USA) which showed absent or thinning myometrial tissue (less than 1 mm) at the placental site and irregularity or disappearance of the retroplacental echolucent area between the myometrium and the placenta.

The morphologic risk factors for carotid atherosclerotic plaque include plaque surface ulceration, thrombosis, lumen surface irregularity, intraplaque hemorrhage, nonhyperechoic plaque, hypoechogenic or predominantly hypoechogenic plaque, echolucent plaque, complex plaque, stenoses grade ≥70%, early- and end-stage calcifications, gray-scale median score in imaging of plaque echogenicity, plaque lipid core presence, lipid-rich plaque, intima-media thickness (IMT), and plaque score.
identified the following ultrasonographic criteria for morbidly adherent placenta: loss/irregularity of the echolucent area between the uterus and the placenta, termed 'clear space'; thinning or interruption of the hyperechoic interface between the uterine serosa and the bladder wall, termed 'bladder line'; presence of turbulent placental lacunae with high-velocity flow (>15 cm/s).
Based on the modified Gray-Weale classification of atherosclerotic plaques [24, 25], 21 plaques were classified as "unstable" (echolucent, low median gray level, GSM [less than or equal to] 25) while 6 as "stable" (echogenic, GSM > 25).
