BACKGROUND: Uterine rupture is a potential life-threatening complication during a trial of labor after cesarean. Single-layer closure of the uterus at cesarean has been associated with an increased risk of uterine rupture when compared to double-layer closure. Lower uterine segment thickness measurement by ultrasound has been used to evaluate the quality of the uterine scar following cesarean and is associated with the risk of uterine rupture. OBJECTIVE: To estimate the impact of previous uterine closure on lower uterine segment thickness...

BACKGROUND: The term cesarean scar pregnancy refers to placental implantation within the scar of a previous cesarean delivery. The rising numbers of cesarean deliveries in the last decades have led to an increased incidence of cesarean scar pregnancy. Complications of cesarean scar pregnancy include morbidly adherent placenta, uterine rupture, severe hemorrhage, and preterm labor. It is suspected that cesarean scar pregnancies that are implanted within a dehiscent scar ("niche") behave differently compared with those implanted on top of a well-healed scar...

OBJECTIVE: A growing body of evidence suggests that the surgical technique for uterine closure influences uterine scar healing, but there is still no consensus about optimal uterine closure during cesarean delivery (CD). The aim of this systematic review and meta-analysis was to compare the effect of single- versus double-layer closure on the risk of uterine scar defect. METHODS: MEDLINE, Scopus, http://ClinicalTrials.gov, the PROSPERO International Prospective Register of Systematic Reviews, EMBASE and the Cochrane Central Register of Controlled Trials were searched from inception of each database until May 2016...

PURPOSE OF REVIEW: Placental implantation abnormalities (PIAs) comprise a large group of disorders associated with significant maternal, fetal, and neonatal morbidity. RECENT FINDINGS: Risk factors include prior uterine surgery/myometrial scarring and the presence of placenta previa with or without prior cesarean delivery. Newly identified risk factors include previous prelabor cesarean delivery and previous postpartum hemorrhage. PIAs contribute substantially to preterm birth with prematurity rates ranging from 38 to 82%...

OBJECTIVE: To evaluate intra- and inter-observer agreement in measurements of the cesarean scar niche and the residual myometrial thickness (RMT) using 3-dimensional (3D) transvaginal ultrasonography. STUDY DESIGN: Fifty-eight uterine 3D volumes from women with deep cesarean scar niches were evaluated. 3D volumes were obtained six to fifteen months after a primary cesarean section. Evaluation of the 3D volume was performed in a standardized multiplanar view. Two observers independently obtained RMT, cesarean scar niche depth (D), length (L), width (W), and myometrium adjacent to the scar (M)...

OBJECTIVES: To evaluate the normal ranges of lower uterine segment (LUS) thickness throughout pregnancy in women without a previous cesarean and to evaluate the relationship between ultrasound and intraoperative LUS thickness. METHODS: We assessed LUS thickness using transabdominal and transperineal longitudinal scan at each week of gestation, during labour, and in the postpartum period in 1000 pregnant women without previous CS. Secondly, we assessed LUS thickness immediately before CS (using ultrasound) and intraoperatively (using ophthalmic calipers) immediately before delivery of the fetus in 35 women with a previous CS and 29 women without previous CS undergoing elective CS before labour...

BACKGROUND: Incomplete healing of uterine scar after cesarean has been associated with adverse gynecological and obstetrical outcomes. Several studies reported that uterine closure at cesarean influences the healing of uterine scar and the risk of uterine rupture at subsequent pregnancies: the commonly used locked single-layer suture including the decidua being associated with a 4-fold increased risk of uterine rupture. However, data from randomized trials are lacking. OBJECTIVE: We sought to evaluate the impact of 3 techniques of uterine closure after cesarean delivery on uterine scar healing...
