Purpose: Pregnancies complicated by placenta accreta spectrum (PAS) are associated with severe maternal morbidities. The aim of this study is to describe the neonatal outcomes in pregnancies complicated with PAS compared with pregnancies not complicated by PAS.
Methods: A retrospective cohort study conducted at a single tertiary center between 03/2011 and 01/2022, comparing women with PAS who underwent cesarean delivery (CD) to a matched control group of women without PAS who underwent CD.
Objectives: To compare delivery outcomes of pregnancies diagnosed with placenta-accreta-syndrome (PAS) who underwent conservative treatment to patients who underwent cesarean hysterectomy.
Methods: A retrospective study of all women diagnosed with PAS treated in one tertiary medical center between 03/2011 and 11/2020 was performed. Comparison was made between conservative management during cesarean delivery and cesarean hysterectomy.
Background: We aimed to evaluate the association of the duration of the second stage with labor after cesarean (LAC) success and other outcomes among women with one prior cesarean delivery (CD) and no prior vaginal births.
Methods: All women undergoing LAC that reached the second stage of labor from March 2011 to March 2020 were included in this retrospective cohort study. The primary outcome was the mode of delivery by second stage duration.
Length of the second stage of labor among women achieving vaginal birth after cesarean.
Int J Gynaecol Obstet
August 2023
Objective: To characterize the length of the second stage of labor among women completing a first vaginal birth after a cesarean (VBAC), according to the stage of labor during primary cesarean delivery (CD).
Methods: A retrospective cohort study of VBACs between 2011 and 2020. Study groups were divided as follows: CD not in labor, CD in the first stage of labor, and CD in the second stage of labor.
Article Synopsis
- The study aimed to identify risk factors linked to bladder injuries during surgeries for placenta accreta spectrum (PAS) in pregnant women.
- Out of 312 participants, there was a 9.3% rate of bladder injuries, with risk factors including previous cesarean deliveries and preoperative suspicion of placenta percreta.
- Understanding these risk factors can improve preoperative planning and management during PAS surgeries.
Key Message: Trial of labor among women who never delivered vaginally with hypertensive disorder is associated with nearly half the success rate of the general population.
Purpose: To study the trial of labor after cesarean (TOLAC) among women with hypertensive disorders and no prior vaginal delivery.
Methods: A retrospective cohort study was conducted including women with no prior vaginal delivery undergoing TOLAC during 2010-2020.
Purpose: The purpose is to study the association of the fetal sonographic head circumference (SHC) with trial of labor after cesarean (TOLAC) success rate, among women with no prior vaginal deliveries.
Methods: A retrospective case-control study including all women with no prior vaginal delivery undergoing TOLAC during 3/2011-6/2020 with a sonographic estimated fetal weight within one week from delivery. TOLAC success and failure groups were compared.
Prediction of successful trial of labor after cesarean among grand-multiparous women.
Arch Gynecol Obstet
August 2022
Purpose: To determine the factors associated with successful trial of labor after cesarean (TOLAC) among grand-multiparous (GMP) women.
Methods: A retrospective cohort study was conducted, including all GMP women (≥ 5 deliveries) undergoing TOLAC during 3/2011 and 6/2020, delivering a singleton cephalic newborn. Factors associated with successful vaginal delivery were examined by multivariable analysis.
Objective: To estimate the association of the weight difference between the index trial of labor after cesarean (TOLAC) sonographic estimated fetal weight (sEFW) and prior delivery birth weight with TOLAC success rate among women with previous labor dystocia and no prior vaginal delivery.
Methods: A retrospective cohort study including all women with prior cesarean for labor dystocia and no prior vaginal delivery undergoing TOLAC during between March 2011 and June 2020 with a sEFW within 1 week from delivery.
Results: Overall, 168 women were included, of those 107 (63.
Background: Data are scarce on predictors for success of labor after cesarean (LAC) among women delivering without epidural anesthesia (EA). We aimed to study the predictors for success of LAC among women with no prior vaginal delivery that did not use EA.
Methods: A retrospective study including all women undergoing LAC between 3/2011 and 1/2021 with no prior vaginal delivery that did not use EA.
Objective: To study the factors associated with successful trial of labor after cesarean (TOLAC) among women with diabetes and no prior vaginal delivery and compare with TOLAC in nondiabetic women.
Methods: A retrospective study including all women undergoing TOLAC who had no prior vaginal delivery between March 2011 and June 2020 at Sheba Medical Center. Women with diabetic disorders were compared with those without.
Implementation of machine learning models for the prediction of vaginal birth after cesarean delivery.
J Matern Fetal Neonatal Med
October 2022
Objective: Accurate prediction of vaginal birth after cesarean is crucial for selecting women suitable for a trial of labor after cesarean (TOLAC). We sought to develop a machine learning (ML) model for prediction of TOLAC success and to compare its accuracy with that of the MFMU model.
Methods: All consecutive singleton TOLAC deliveries from a tertiary academic medical center between February 2017 and December 2018 were included.
Purpose: To compare the obstetrical and detailed neonatal outcomes of primipara of advanced maternal age conceiving two sequential singleton pregnancies by IVF with those of primipara conceiving twins by IVF.
Methods: A retrospective study of all primiparous women aged ≤ 38 years and conceived by IVF who delivered sequential singletons or delivered twins at a single tertiary university affiliated medical center between 2011 and 2019. We performed two main comparisons: 1.
Trial of Labor After Cesarean in Adolescents - A Multicenter Study.
J Pediatr Adolesc Gynecol
August 2020
Study Objective: Data regarding trial of labor after cesarean delivery (TOLAC) among young women are limited. The aim of this study was to assess the TOLAC success rate and its related factors among adolescent women who had never delivered vaginally.
Design: A multicenter retrospective cohort study of all adolescent women aged ≤21 years with a history of 1 previous cesarean delivery, who delivered in 2 tertiary medical centers during 2007-2019.
