Ultrasound diagnosis of caesarean scar defects

Caesarean section (CS) scar defects are seen in up to 19% of women post lower segment caesarean section. Ultrasound and in particular transvaginal ultrasound, with or without saline, is the imaging modality of choice to delineate such defects. There are limited data available however which enable clinicians to quantify the risk of potential sequelae in women with a demonstrable CS scar defect.
