Transvaginal Ultrasound Assessment of Caesarean Section Uterine Scar Closed by Single Versus Double Layer

Cesarean section (CS) is one of the most commonly performed major abdominal operations in women in both high and low-income countries. Single-layer closure using a running locking stitch is associated with decreased operative time and fewer additional haemostasis sutures. An extensive Canadian study found a fourfold increase in the risk of uterine rupture in a woman who had a single layer in their previous pregnancy. Transvaginal ultrasound is a validated tool for evaluating uterine scar defects, commonly referred to as a niche. It is used to asses the uterine scar thickness in a women with previous cesarean delivery.
