Endometrium-Free Closure Technique During Cesarean Delivery for Reducing the Risk of Niche Formation and Placenta Accreta Spectrum Disorders.

Objective: To examine the prevalence and severity of postcesarean residual niche, evaluated using saline infusion sonohysterography, in an expanded cohort of women with one prior cesarean delivery and to assess the effect of uterine closure technique on the risk of placenta accreta spectrum (PAS) disorders.

Methods: This secondary analysis includes 70 patients who underwent saline infusion sonohysterography after one prior cesarean delivery. Patients were grouped according to hysterotomy closure technique: two-layer endometrium-free closure (technique A), and two- or one-layer routine closures (technique B).

Outcome Reporting in Studies Investigating Treatment for Caesarean Scar Ectopic Pregnancy: A Systematic Review.

Background: Caesarean scar ectopic pregnancy (CSEP) is associated with significant maternal and foetal morbidity. However, the optimal treatment remains unknown.

Objectives: The aim of this study was to review outcomes reported in studies on CSEP treatment and outcome reporting quality.

Telemedicine ultrasound assessment for placenta accreta spectrum: Utility and interobserver reliability of asynchronous remote imaging review.

Objective: Management of patients with placenta accreta spectrum (PAS) by trained multidisciplinary teams is associated with improved outcomes. Ultrasound can predict intraoperative risks, but expert ultrasound imaging of PAS is often limited. Telemedicine is used increasingly in obstetrics, permitting expert consultation when essential resources are not available locally.

Early first-trimester transvaginal ultrasound screening for cesarean scar pregnancy in patients with previous cesarean delivery: analysis of the evidence.

Obstetric hemorrhage is a leading cause of maternal morbidity and mortality. An important etiology of obstetric hemorrhage is placenta accreta spectrum. In the last 2 decades, there has been increased clinical experience of the devastating effect of undiagnosed, as well as late diagnosed, cases of cesarean scar pregnancy.

Clinical Practice Guidelines and Recommendations by the World Association of Perinatal Medicine and Perinatal Medicine Foundation: Reporting Suspected Findings from Fetal Central Nervous System Examination.

These guidelines follow the mission of the World Association of Perinatal Medicine, in collaboration with the Perinatal Medicine Foundation, which brings together groups and individuals worldwide, with the aim to improve prenatal detection of central nervous system anomalies and the appropriate referral of pregnancies with suspected fetal anomalies. In addition, this document provides further guidance for healthcare practitioners with the goal of standardizing the description of ultrasonographic abnormal findings.

The effect of uterine closure technique on cesarean scar niche development after multiple cesarean deliveries.

Objectives: To use saline infusion sonohysterography (SIS) to evaluate the effect of uterine closure technique on niche formation after multiple cesarean deliveries (CDs).

Methods: Patients with at least one prior CD were evaluated for niche via SIS. Subgroups of any number repeat CD (>1 prior), lower-order CD (<4 prior), and higher-order CD (≥4 prior) were analyzed, stratifying by hysterotomy closure technique at last cesarean preceding imaging; techniques included Technique A (endometrium-free double-layer closure) and Technique B (single- or double-layer routine endo-myometrial closure).

The use of pressure balloons in the treatment of first trimester cesarean scar pregnancy.

Cesarean scar pregnancy (CSP) is among the most severe complications of cesarean delivery. CSP refers to the abnormal implantation of the gestational sac in the area of the prior cesarean delivery (CD), potentially leading to severe hemorrhage, uterine rupture, or development of placenta accreta spectrum disorders (PAS). The management of women with CSP has not been standardized yet.

Global variation and outcomes of expectant management of CSP.

The incidence of Cesarean scar pregnancies (CSPs) is rising globally. Ultrasound criteria for the diagnosis of CSPs have been described by the International Society of Ultrasound in obstetrics and gynecology and appear to be well used in various centers around the world. There is no guidance on best practices for expectant management of CSP, and there is considerable variation in how this is offered globally.

A new era in teaching: how advanced optical recording technology could change the postcesarean delivery complication conundrum.

Background: The last 4 decades have seen increased complications after cesarean deliveries. Despite an incomplete understanding of their etiology, surgical practices have been adopted, creating disproportionate morbidity and the absence of preventive strategies. Additional research tools are needed for further investigation.

Placenta accreta spectrum disorders in the first trimester: a systematic review.

Placenta accreta spectrum (PAS) disorders involve an abnormality in the implantation of the placenta, being rarely diagnosed in the first trimester. To conduct a systematic review of the risk factors, clinical and imaging features, and outcomes of histopathologically confirmed cases of PAS disorders in the first trimester of pregnancy. Different databases including PubMed, MEDLINE Complete, Scopus, Web of Science, EMBASE, SciELO, LILACS, and Ovid were reviewed up to November 2018.

Methodological Quality of Fetal Brain Structure Charts for Screening Examination and Targeted Neurosonography: A Systematic Review.

Introduction: Several fetal brain charts have been published in the literature and are commonly used in the daily clinical practice. However, the methodological quality of these charts has not been critically appraised.

Material And Methods: MEDLINE, EMBASE, CINAHL, and the Web of Science databases were searched electronically up to December 31, 2020.

The Impact of Uterine Incision Closure Techniques on Post-cesarean Delivery Niche Formation and Size: Sonohysterographic Examination of Nonpregnant Women.

Objective: To compare the prevalence and size of residual niche in the nongravid uterus following Cesarean delivery (CD) with different hysterotomy closure techniques (HCTs).

Methods: Saline infusion sonohysterogram (SIS) was performed in women after one prior CD, documenting the presence or absence of a postoperative niche and measuring its depth, width, length, and residual myometrial thickness. Women were grouped by HCT: Technique A (endometrium-free) and Technique B (routine non-endometrium-free).

Reference ranges for fetal brain structures using magnetic resonance imaging: systematic review.

Objective: To evaluate the methodology of studies reporting reference ranges for fetal brain structures on magnetic resonance imaging (MRI).

Methods: MEDLINE, EMBASE, CINAHL and the Web of Science databases were searched electronically up to 31 December 2020 to identify studies investigating biometry and growth of the fetal brain and reporting reference ranges for brain structures using MRI. The primary aim was to evaluate the methodology of these studies.
