Breech presentation

Yu Sun Bin, Christine L Roberts, Michael C Nicholl, Natasha Nassar, Jane B Ford
BACKGROUND: Recent population-wide changes in perinatal risk factors may affect rates of breech presentation at birth, and have implications for the provision of breech services and training in breech management. AIMS: To investigate whether changes in maternal and pregnancy characteristics explain the observed trend in breech presentation at term. MATERIALS AND METHODS: All singleton term (≥37 week) births in New South Wales during 2002-2012 were identified through birth and associated hospital records...

BACKGROUND: External cephalic version (ECV) increases the likelihood of a vaginal delivery in patients with breech presentation. Our objective was to determine the rate of cephalic vaginal delivery in women undergoing ECV after PROM. METHODS: We performed a systematic review of all case reports, case series, and clinical trials of patients undergoing an ECV after PROM ≥ 24 weeks. Maternal demographics and outcome data were obtained. The primary outcome was rate of cephalic vaginal delivery...

Importance: Perinatal complications may increase the risk of obsessive-compulsive disorder (OCD). Previous reports were based on small, retrospective, specialist clinic-based studies that were unable to rigorously control for unmeasured environmental and genetic confounding. Objective: To prospectively investigate a wide range of potential perinatal risk factors for OCD, controlling for unmeasured factors shared between siblings in the analyses. Design, Setting, and Participants: This population-based birth cohort study included all 2 421 284 children from singleton births in Sweden from January 1, 1973, to December 31, 1996, who were followed up through December 31, 2013...

Cystic endosalpingiosis refers to the existence of heterotopic cystic müllerian tissue resembling structures of the fallopian tubes. We report a case of florid cystic endosalpingiosis discovered in a pregnant woman during a scheduled cesarean section and review the current knowledge of this disease. A 30-year-old woman with a twin pregnancy attended the hospital day unit at term. The first twin was in a breech presentation and a cesarean section was scheduled. During the procedure the uterine fundus and part of the body were seen completely seeded with multitude of cyst-like structures resembling hydatids of Morgagni...

OBJECTIVES: To determine the trends of cesarean delivery rate among twin pregnancies from 2006 to 2013. STUDY DESIGN: This is a population-based, cross-sectional analysis of twin live births from United State birth data files of the National Center for Health Statistics for calendar years 2006 through 2013. We stratified the population based on the gestational age groups, maternal race/ethnicity, advanced maternal age (AMA) which was defined by age more than 35 years and within the standard birth weight groups (group 1: birth weight 500-1499g, group 2: birth weight 1500-2499g and group 3: birth weight >2500g)...

BACKGROUND: Studies have shown that cesarean delivery is associated with fewer subsequent births relative to vaginal delivery, but it is unclear whether confounding by pregnancy intention or indication for surgery explained these results. We evaluated the association between cesarean delivery and subsequent fecundability among 910 primiparous women after singleton live birth. METHODS: In a cohort of Danish women planning pregnancy (2007-2012), obstetrical history was obtained via registry linkage; time-to-pregnancy and covariate data were collected via questionnaire...

BACKGROUND: Existing studies regarding women's experiences surrounding an External Cephalic Version (ECV) report on women who have a persistent breech post ECV and give birth by caesarean section, or on women who had successful ECVs and plan for a vaginal birth. There is a paucity of understanding about the experience of women who attempt an ECV then plan a vaginal breech birth when their baby remains breech. The aim of this study was to examine women's experience of an ECV which resulted in a persistent breech presentation...

Caesarean delivery was performed in 20% of all deliveries in France in 2010 and this rate has remained unchanged during the last 10 years. Indications to perform this procedure are well defined, especially in case of scarred uterus, twin pregnancies, macrosomia or breech presentation. Surgical (haemorrhage, urinary or intestinal tract injury) and anaesthetic (hypotension after regional anaesthesia, difficult intubation and aspiration after general anaesthesia) complications may occur during the procedure. Complications may also be encountered in the early postoperative period (haemorrhage, infection, venous thromboembolism) but also on the long-term, such as placenta accreta or uterine rupture which may significantly impact obstetric outcomes...

BACKGROUND: Even if lower vaginal delivery success rates and impaired neonatal short-term outcomes have been reported for primiparous women with breech presentation, vaginal breech delivery remains an option for carefully selected patients. Because Magnetic resonance imaging (MRI) pelvimetry can provide additional information on maternal pelvic morphology, we sought to identify new MRI parameters that predict successful vaginal breech delivery. METHODS: In this retrospective unicentre study, 240 primiparous women with breech presentation at term underwent MRI pelvimetry...

Stillbirths are among the most common pregnancy-related adverse outcomes but are more common in low-income and middle-income countries than in high-income countries. In high-income countries, most stillbirths occur early in the preterm period, whereas in low-income and middle-income countries, most occur in term or in late preterm births. In low-income and middle-income countries, conditions, such as prolonged or obstructed labor, placental abruption, preeclampsia/eclampsia, fetal growth restriction, fetal distress, breech and other abnormal presentations, and multiple births, are associated with stillbirth...

BACKGROUND: Several studies have investigated the efficacy of moxibustion with or without acupuncture for fetal version, but the results are discordant. Meta-analyses pointed out the need for robust, methodologically sound, randomized controlled trials. OBJECTIVE: The objective of this study was to assess the effectiveness of acupuncture with fire needling on acupoint BL67 for version of breech presentation. STUDY DESIGN: This was a randomized, sham-controlled, single-blinded trial, which took place in Strasbourg teaching maternity hospital, France...

BACKGROUND: To evaluate the extent of the difference in elective (ELCS) and emergency (EMCS) caesarean section (CS) rates between nulliparous women in public maternity hospitals in Ireland by model of care, and to quantify the contribution of maternal, clinical, and hospital characteristics in explaining the difference in the rates. METHODS: Cross-sectional analysis using a combination of two routinely collected administrative databases was performed. A non-linear extension of the Oaxaca-Blinder method is used to decompose the difference between public and private ELCS and EMCS rates into the proportion explained by the differences in observable maternal, clinical, and hospital characteristics and the proportion that remains unexplained...

BACKGROUND: We aimed to define the frequency and predictors of successful external cephalic version in a nationally-representative cohort of women with breech presentations and to compare maternal outcomes associated with successful external cephalic version versus persistent breech presentation. METHODS: Using the Nationwide Inpatient Sample, a United States healthcare utilization database, we identified delivery admissions between 1998 and 2011 for women who had successful external cephalic version or persistent breech presentation (including unsuccessful or no external cephalic version attempt) at term...

Abnormal placental attachments, such as placenta accreta, increta or percrata, can result in increased morbidity and mortality because of the risk of severe postpartum haemorrhage. We aimed to present the management of spinal anaesthesia and surgical approach for emergent caesarean section because of vaginal bleeding in a multiparous pregnant woman with placenta previa at 36 weeks' gestation. Hyperbaric bupivacaine 12 mg, fentanyl 10 μg and morphine 150 μg were intrathecally administered for spinal anaesthesia...

BACKGROUND: Trial evidence supports a policy of caesarean section for singleton breech presentations at term, but vaginal breech birth is considered a safe option for selected women. AIMS: To provide recent Australian data on outcomes associated with intended mode of delivery for term breech singletons in women who meet conservative eligibility criteria for vaginal breech birth. MATERIALS AND METHODS: Birth and hospital records from 2009 to 2012 in New South Wales were used to identify women with nonanomalous pregnancies who would be considered eligible for vaginal breech birth...
