Ultrasonographic Evaluation of Lower Uterine Segment Scar in Women with Previous Cesarean Section
Abstract: The global rise in cesarean section rates has resulted in an increasing number of pregnancies complicated by uterine scars. Assessment of lower uterine segment (LUS) scar integrity is essential to predict complications such as uterine rupture, scar dehiscence, and abnormal placentation. Ultrasonography has emerged as the most practical and non-invasive imaging modality for evaluating cesarean scars during pregnancy. This review summarizes current evidence regarding ultrasonographic evaluation of the lower uterine segment scar in women with previous cesarean section. Parameters such as scar thickness, residual myometrial thickness, scar morphology, and echogenicity are discussed along with their clinical significance. The predictive value of LUS thickness in determining the risk of uterine rupture and guiding mode of delivery is highlighted. Conclusion: Ultrasonography remains an essential tool for risk stratification and management planning in pregnancies following cesarean section. Standardization of measurement techniques and establishment of universally accepted cut-off values are needed to improve clinical utility.
