ultrasound thickness cesarean

Sevan A Vahanian, Anthony M Vintzileos
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 compare the appearance and measurement of Cesarean hysterotomy scars in non-pregnant women and in a subsequent pregnancy at 11-14 weeks. METHODS: In a prospective cohort study we included women aged 18-35 years with one previous Cesarean delivery (CD) performed at ≥37 gestational weeks. Women were examined with saline contrast sonohysterography 6-9 months after CD. A scar defect was defined as large if the scar thickness (ST) was ≤2.5 mm. Women were followed up and those who became pregnant were examined with transvaginal ultrasound at 11-14 weeks...

STUDY OBJECTIVE: Owing to the increase in cesarean sections (C-sections) worldwide, long-term complications such as postmenstrual spotting, chronic pelvic pain, and C-section scar ectopic pregnancies have created a new medical era of gynecologic disease. A new type of vaginal repair is evaluated to repair C-section diverticulum (CSD) and rebuild the muscular layer to improve symptoms of abnormal uterine bleeding and decrease the risk of uterine rupture. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2)...

BACKGROUND: Choice of delivery route after previous cesarean delivery can be difficult because both trial of labor after cesarean delivery and elective repeat cesarean delivery are associated with risks. The major risk that is associated with trial of labor after cesarean delivery is uterine rupture that requires emergency laparotomy. OBJECTIVE: This study aimed to estimate the occurrence of uterine rupture during trial of labor after cesarean delivery when lower uterine segment thickness measurement is included in the decision-making process about the route of delivery...

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...

STUDY OBJECTIVE: To demonstrate the technique of laparoscopic repair of a large cesarean scar defect (isthmocele). DESIGN: Case report (Canadian Task Force classification III). SETTING: Cesarean scar defect, also known as an isthmocele, is the result of incomplete healing of the isthmic myometrium after a low transverse uterine incision performed for cesarean section. Although mostly asymptomatic, it may cause menstrual abnormalities (typically postmenstrual spotting), chronic pelvic pain, and secondary infertility...

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...

INTRODUCTION AND HYPOTHESIS: We aimed to determine whether anal sphincter complex (ASC) measurements on translabial ultrasound (TL-US) were related to anal incontinence (AI) or fecal incontinence (FI) symptoms 6 months postpartum. METHODS: A prospective cohort of primiparous women underwent TL-US 6 months after a vaginal birth (VB) or cesarean delivery (CD). Muscle thickness was measured at 3, 6, 9, and 12 o'clock positions of the external anal sphincter (EAS), the same four quadrants of the internal anal sphincter (IAS) at proximal, mid, and distal levels, and at the bilateral pubovisceralis muscle (PVM)...

OBJECTIVES: To evaluate the accuracy of ultrasound in the diagnosis of placenta accreta and its variants, and to assess the impact of prenatal diagnosis in our population. METHODS: A total of 314 women with placenta previa were enrolled prospectively and underwent transabdominal and transvaginal ultrasound examinations. An ultrasound diagnosis (grayscale and color/power Doppler) of placental attachment disorder (PAD) was based on the detection of at least two of the following ('two-criteria system'): loss/irregularity of the retroplacental clear zone, thinning/interruption of the uterine serosa-bladder wall interface, turbulent placental lacunae with high velocity flow, myometrial thickness < 1 mm, increased vascularity of the uterine serosa-bladder wall interface, loss of vascular arch parallel to the basal plate and/or irregular intraplacental vascularization...
