Embarazo triple espontáneo en una paciente con útero didelfo: reporte de un caso y revisión de la bibliografía / Spontaneous triplet pregnancy in a patient with uterus didelphys: report of a case and review of the literature

Resumen ANTECEDENTES: Las anomalías müllerianas implican la desviación de la anatomía normal del aparato reproductor femenino debido a un desarrollo embriológico alterado. Padecer alguna de estas anomalías, en cualquier escenario de su amplio espectro, suele asociarse con infertilidad o desenlaces obstétricos adversos, como la pérdida gestacional temprana o el parto pretérmino. CASO CLÍNICO: Paciente de 21 años, sin antecedentes patológicos relevantes, con dos embarazos finalizados: el primero por cesárea y el segundo por parto (la cesárea se indicó por la presentación podálica, a las 32 semanas). Acudió a un centro de referencia de la ciudad de Medellín, Colombia (Clínica Universitaria Bolivariana) a la primera consulta prenatal a las 17 semanas y 4 días de embarazo, motivada por un cuadro clínico de cólico biliar, sin requerimiento de intervenciones. Se trataba de embarazo triple, monocorial, triamniótico, con diagnóstico de útero didelfo a las 17 semanas y 1 día, con ambos cuellos uterinos reportados en 38 mm. La gestación finalizó a las 28 semanas y 4 días con el nacimiento de tres niños, quienes luego de superar los retos de la prematurez, en la actualidad llevan una vida normal. CONCLUSIONES: Las anomalías müllerianas, en su amplio espectro de manifestación clínica, son una condición que se asocia con una mayor frecuencia de desenlaces adversos materno-perinatales que se incrementan cuando la anomalía se relaciona con un embarazo múltiple. En la bibliografía actual no abundan los reportes de casos que combinen ambas condiciones, ni con recomendaciones oficiales estandarizadas para la atención médica de las pacientes, sobre todo para el escenario de embarazo triple y útero didelfo.

Abstract BACKGROUND: Müllerian anomalies involve deviation from the normal anatomy of the female reproductive tract due to altered embryological development. Having any of these anomalies, in any of their broad spectrum, is often associated with infertility or adverse obstetric outcomes, such as early gestational loss or preterm delivery. CLINICAL CASE: 21-year-old female patient, with no relevant pathological history, with two pregnancies terminated: the first by cesarean section and the second by delivery (the cesarean section was indicated due to breech presentation, at 32 weeks). She attended a referral center in the city of Medellín, Colombia (Clínica Universitaria Bolivariana) for the first prenatal consultation at 17 weeks and 4 days of pregnancy, motivated by a clinical picture of biliary colic, without requiring interventions. The pregnancy was triple, monochorionic, triamniotic, with a diagnosis of didelphic uterus at 17 weeks and 1 day, with both cervix reported at 38 mm. The gestation was terminated at 28 weeks and 4 days with the birth of three infants, who after overcoming the challenges of prematurity, are now living normal lives. CONCLUSIONS: Mullerian anomalies, in their broad spectrum of clinical presentation, are a condition that is associated with an increased frequency of adverse maternal-perinatal outcomes that are increased when the anomaly is associated with multiple pregnancy. The current literature does not abound with case reports combining both conditions, nor with standardized official recommendations for patient care, especially in the setting of triple pregnancy and didelphic uterus.

Factors influencing success of external cephalic version and their clinical significance / 中华围产医学杂志

Objective:To analyze the factors influencing the success rate of external cephalic version (ECV) and to create a preoperative scoring scale for stratified management of pregnant women who were preparing for ECV.Methods:This prospective study was conducted on singleton pregnant women who underwent ECV without anesthesia in Fujian Maternity and Child Health Hospital from January 1, 2017, to December 31, 2019. Univariate (two independent samples t-test, Mann-Whitney U test, and Chi-square test) and multivariate logistic regression were used to screen the clinical characteristics affecting the success of ECV, and receiver operating characteristic (ROC) curve was used to determine the cut-off value and convert quantitative variables into dichotomous variables. The independent variables were scored according to the regression coefficient in multivariate logistic regression analysis, and then a preoperative scoring scale was created. The ROC curve was used to calculate the cut-off value for the scoring scale. The subjects were divided into low and high score groups according to the cut-off value. The area under the ROC curve was used for evaluating the effectiveness of the scale in predicting the success of ECV. The success rate of ECV, difficulty of the operation and mode of delivery were compared between the two groups. Results:A total of 1 338 pregnant women met the inclusion criteria during the study period. After the exclusion of 885 women, 165 refused ECV in favor of direct cesarean section, 27 spontaneously converted to cephalic position before ECV, 261 who voluntarily accepted ECV were finally enrolled. ECV succeeded in 202 cases and failed in 59. (1) Favorable factors for ECV without anesthesia were the distance between the fetal breech and ischial spine <－3.5 cm ( OR=0.177, 95% CI: 0.071-0.438, P=0.009), the sum of the fundal height and the station of the fetal breech based on the ischial spine <30.25 cm ( OR=0.225, 95% CI: 0.094-0.537, P=0.001), amniotic fluid index ≥12 cm ( OR=0.399, 95% CI: 0.164-0.969, P=0.042), the surgeon's ability to hold the fetal head or breech with one hand ( OR=0.241, 95% CI: 0.098-0.589, P=0.002; OR=0.219, 95% CI: 0.087-0.546, P=0.001), and the fetal head located on the right or left upper abdomen of the mother ( OR=0.184, 95% CI: 0.059-0.568, P=0.003; OR=0.253, 95% CI: 0.084-0.760, P=0.014). (2) The area under the ROC curve of the preoperative score for predicting the success of ECV was 0.881 (95% CI: 0.821-0.941) and the cut-off value was 5.5. The subjects were divided into low (0-5 scores) and high (6-11 scores) score groups and the area under the ROC curve for predicting the success of ECV by grouping was 0.843 (95% CI: 0.774-0.912). Compared with the low score group, the high score group had a shorter ECV duration [2.0 min (0.5-10.0 min) vs 10.0 min (0.9-25.8 min), Z=－6.83, P<0.001], less attempts [1.0 times (1.0-4.0 times) vs 3.0 times (1.0-5.0 times), Z=－8.41, P<0.001], higher success rate [92.7% (190/205) vs 21.4% (12/56), χ2=127.64, P<0.001], higher rate of vaginal birth [75.4% (147/195) vs 18.5% (10/54)] and lower cesarean section rate [24.6% (48/195) vs 81.5% (44/54)] ( χ2=58.70, P<0.001). Conclusions:Preoperative scoring based on the factors influencing the success rate of ECV (the distance between the fetal breech and ischial spine, the sum of the fundal height and the station of the fetal breech based on the ischial spine <30.25 cm, amniotic fluid index ≥12 cm, the surgeon's ability to hold the fetal head or breech with one hand, and the fetal head locating on the right or left upper abdomen of the mother) is conducive to the individualized evaluation of the difficulty and the success rate of ECV as well as the success rate of vaginal delivery after ECV, which can provide a reference for clinical stratified management of ECV patients.

Learning curve for ultrasound-guided external cephalic version without anesthesia in full-term and near-term pregnancies / 中华围产医学杂志

Objective:To evaluate the effects of physician skills on the success rate of the external cephalic version (ECV) and investigate the learning curve for ECV.Methods:A retrospective study of 97 pregnant women who underwent ECV at the First Affiliated Hospital of Nanjing Medical University from March 2019 to August 2021 was performed. Patients were divided into multipara and primipara groups. The success rate of ECV and morbidity were compared between the two groups, and the learning curve for ECV was evaluated using cumulative sum analysis (CUSUM).Results:(1) Patients in the multipara group were older than those in the primipara group [(33.0±3.4) vs (29.2±3.0) years, t=－5.57, P<0.001]. No significant difference was found in other baseline data between the two groups. (2) The overall ECV success rate was 61.9% (60/97), and a higher success rate was observed in the multipara group [93.3% (28/30) vs 47.8% (32/67), χ 2=18.24, P<0.001]. Fetal heart rate deceleration (5.2%, 5/97), vaginal bleeding (1.0%, 1/97), premature rupture of membranes (1.0%, 1/97), and fetal distress (1.0%, 1/97) were the main complications. (3) The CUSUM analysis showed that it needed 53 primiparas for a physician to obtain a 50% consistent success rate ( R2=0.91, H=－3.27, Y=52.16) and seven multiparas to achieve a 70% consistent success rate ( R2=0.99, H=－1.635, Y=6.60). Conclusions:Parity and operator skills have a significant influence on the success of ECV. A physician with standardized training will manage non-anesthesia ECV skillfully in full-term and near-term pregnancies after practice on 50 primiparae or approximately ten multiparae. It is recommended to start with the multiparae for learning ECV to build up confidence and promote the implementation of ECV.

Correction rates and safety of acupuncture and moxibustion for treating breech presentation / 全日本鍼灸学会雑誌

[PURPOSE] To evaluate the efficacy and safety of acupuncture and moxibustion treatments in breech presentation, we report correction rates and adverse events for correcting breech presentation in our department.[PARTICIPANTS AND METHODS] Subjects were pregnant women who were diagnosed with breech presentation in our obstetrics and gynecology department and started acupuncture and moxibustion treatment between April 1, 2009 and October 31, 2018. The target patients were retrospectively investigated by medical records. The main items investigated were the status of the pregnant women at the time of acupuncture and moxibustion initiation (presence or absence of threatened preterm labor), treatment position (sitting or lateral position), correction rates and occurrence of adverse events. Successful correction was defined as the rate of head position after acupuncture and moxibustion treatments. Adverse events were defined as "unfavorable medical events occurring during or after treatment, regardless of causation."[RESULTS] There were 371 pregnant women in the study; among them 57 women were diagnosed with threatened preterm labor at the start of acupuncture and moxibustion treatment, including 21 pregnant women who were in the hospital. The sitting position was used for treatment for 45.2% (168 cases) of subjects and lateral position was used for 54.7% (203 cases). The correction rates were 72.2% (268/371). In pregnant women with threatened preterm labor who were hospitalized at the time of acupuncture and moxibustion initiation, the correction rates were 28.6% (6/21 cases), which was significantly lower than that of outpatient pregnant women. There was no significant difference in the rate of correction by treatment position between sitting and lateral position. There were no adverse events of vagal reflexes when the left lateral position was treated. The frequency of adverse events per number of procedures was 1.1% (21/1916) and per number of cases was 5.7% (21/371 cases). There were two cases of rupture of membranes with no apparent causal relationship.[CONCLUSION] The safest position for treatment in pregnant women was considered to be the left lateral position. Most of the adverse events were minor or moderate, but there were two cases of rupture of membranes with no apparent causal relationship. When performing acupuncture and moxibustion for breech presentation, it is necessary to work closely with the patient's obstetrician.

Is vaginal breech delivery still a safe option? / Será o parto pélvico vaginal uma opção segura?

Abstract Objective: To determine whether there was any difference in neonatal and maternal outcomes between breech vaginal delivery and cephalic vaginal delivery. Methods: A retrospective, case-control study was conducted between January 2015 and December 2017 in a Portuguese hospital. A total of 26 cases of breech vaginal delivery were considered eligible and 52 pregnant women formed the control group. Results: Induced labor was more frequent in the breech vaginal delivery group (46% versus 21%, p = 0.022). Episiotomy was more common in the breech vaginal delivery group (80% versus 52%, p = 0.014), and one woman had a 3rd degree perineal laceration. Newborns in the study group had a lower birthweight (2,805 g versus 3,177 g, p < 0.001). There was no significant difference in the neonatal outcomes. Conclusion: The present study showed that breech vaginal delivery at term compared with cephalic presentation was not associated with significant differences in neonatal and maternal morbidity. It also suggests that breech vaginal delivery remains a safe option under strict selection criteria and in the presence of an experienced obstetrician.

Resumo Objetivo: Avaliar se existem diferenças nos desfechos perinatal e materno entre os partos pélvicos vaginais e eutócicos. Métodos: Realizou-se um estudo retrospectivo, caso controle, entre janeiro de 2015 e dezembro de 2017 em um hospital terciário em Portugal. Foram incluídos 26 casos de parto pélvico vaginal e o grupo controle foi formado por 52 grávidas. Resultados: A indução do trabalho de parto ocorreu com mais frequência no grupo do parto pélvico vaginal (46% versus 21%, p = 0.022), bem como a realização de episiotomia (80% versus 52%, p = 0.014). Verificou-se um caso de laceração perineal de 3° grau. Os recém-nascidos do grupo de estudo apresentaram um peso inferior ao nascimento (2.805 g versus 3.177 g, p < 0.001). Em relação aos desfechos perinatais, não se observaram diferenças estatisticamente significativas. Conclusão: O presente estudo mostrou que o parto pélvico vaginal no termo quando comparado com o parto eutócico não se associou a diferenças estatisticamente significativas na morbidade perinatal e materna, e sugere ainda que o parto pélvico vaginal parece ser uma opção segura em casos rigorosamente selecionados e na presença de um obstetra experiente.

Pregnancy outcome of external cephalic version in singleton pregnancy with breech presentation at term

Background: Breech delivery is associated with poor perinatal outcomes irrespective of the route of delivery. External cephalic version can be a useful tool in management of breech presentation at term by converting it to a cephalic presentation. A study was conducted to evaluate maternal and neonatal outcome of external cephalic version in singleton pregnancies with breech presentation in third trimester.Methods: A prospective observational study was carried out at a tertiary care hospital over a period of 2 years. This study included a total of 65 uncomplicated cases of breech presentation who fulfilled the inclusion criteria. External cephalic version was carried out after 36 weeks of period of gestation in primigravida and after 37 weeks in multigravida women. These patients were followed up till delivery and data was collected and analysed regarding the mode of delivery, maternal and fetal outcome.Results: External cephalic version was successful in 41 patients with a success rate of 63%. Out of them, vaginal delivery could be achieved in 31 cases (75.6%) and LSCS was done for rest of the 10 cases. The success rate was higher in multigravida ladies compared to primigravida ladies. No major procedure related adverse event was noticed in our study.Conclusions: External cephalic version is a very safe and easy procedure which can reduce the rate of cesarean delivery in singleton pregnancies with breech presentation. The results of this study are in favor of wider practice of this procedure in selected cases.

A prospective observational study of breech pregnancy in a tertiary care centre

Background: Breech presentation is the commonest of all mal presentations. Vaginal delivery of breech presentation at term is associated with a much higher perinatal mortality and morbidity than that of vertex presentation.Methods: This prospective study was carried out in the department of obstetrics and gynaecology, S. S. G. Hospital, Baroda for a period of six months from 1st May 2019 to 31st October 2019. Out of a total number of 4476 deliveries, 159 were breech pregnancy. It included all the women admitted in labour room or ward who delivered with clinical or ultrasound diagnosis of breech presentation after 20 weeks of gestation.Results: In the present study incidence of breech pregnancy was 3.6%. Authors observed the highest incidence of breech pregnancy in the age group of 20 to 25 years. Maximum (62.9%) cases delivered after 37 weeks of gestation. In our study 62.3% cases were primigravida and 37.7% were multigravida. Majority of cases (77.4%) delivered by caesarean section. Among all the babies born 50.6% were having birth weight of less than 2.5 kg.Conclusions: Authors need to study and analyse all cases of breech pregnancy individually to decide the management and mode of delivery depending on cases to case basis and expertise of the staff available. Delivery of breech foetus should be conducted by experience obstetrician after appropriate consent from pregnant women and her relatives.

Height of elevated fetal buttock for prediction of successful external cephalic version

14 cm, and HOB >7.8 cm were 10.80 (95% confidence interval [CI], 1.57–74.94), 5.26 (95% CI, 1.06–26.19), and 10.50 (95% CI, 1.03–107.12), respectively. Areas under the curve (AUCs) for AFI, HOB, and parity were 0.66 (95% CI, 0.54–0.78), 0.74 (95% CI, 0.64–0.85), and 0.69 (95% CI, 0.62–0.76), respectively. HOB had the largest AUC, but there were no significant differences among the AUCs of other factors. The cut-off value of HOB was 6 cm.CONCLUSION: This study showed that the AUC of HOB was greater than that of parity and AFI, although it was not statistically significant. As HOB is a noninvasive and comprehensive marker to predict successful ECV, consideration of HOB would be helpful before conducting ECV. Further studies are needed.

Breech presentation delivery care: A review of childbirth semiology, mechanism and care / Atención del parto con feto en presentación pelviana: revisión de la semiología, el mecanismo y la atención del parto

RESUMEN Objetivo: revisar los conceptos que subyacen al trabajo de parto con feto en presentación pelviana, su semiología y las maniobras obstétricas que facilitan un resultado materno perinatal exitoso. Materiales y métodos: a partir de un caso hipotético que ambienta de manera práctica el tema, se crea un documento explicativo construido a partir de una revisión narrativa, en donde se examinan los preceptos relacionados con el diagnóstico, el mecanismo del parto en presentación pelviana y el manejo intraparto de la gestante, con énfasis en la adecuada ejecución de las maniobras que facilitan la extracción fetal. Resultados: el parto en presentación pelviana debe ser atendido por vía vaginal cuando se encuentra en periodo expulsivo con encajamiento cumplido. Para su diagnóstico y atención es esencial hacer una adecuada identificación de la presentación, así como conocer su fisiología, la indicación y adecuada ejecución de las maniobras obstétricas que facilitan un parto sin complicaciones. Conclusiones: el mecanismo del parto en presentación pelviana es complejo y requiere, cuando no hay otra alternativa para la atención, que tanto el obstetra como el médico general conozcan su fisiología y las múltiples maniobras obstétricas que facilitan obtener buen resultado materno perinatal.

ABSTRACT Objective: To review the concepts underlying breech presentation delivery as well as the semiology and the obstetric maneuvers contributing to a successful perinatal maternal outcome. Materials and methods: Based on a hypothetical scenario to set the stage for a practical approach to the topic, an explanatory paper built on a narrative review is created in order to examine the principles related to diagnosis, mechanism of delivery and maternal care, emphasizing maneuvers to ease fetal extraction. Results: Breech presentation delivery must be managed through the vaginal canal when already in the expulsion phase with fetal engagement. For diagnosis and care, it is essential to know the unique semiology and physiology of this condition as well as the obstetric maneuvers to facilitate an uncomplicated delivery. Conclusions: The mechanism of childbirth in breech presentation is complex and requires knowledge of its physiology and multiple obstetric maneuvers on the part of the obstetrician as well as the general practitioner, in order to ensure adequate care when there is no other option.

Reviving external cephalic version: a review of its efficacy, safety, and technical aspects

Currently, the rate of cesarean sections being performed in Korea is approximately 40%, with Korea ranking 4th among the Organization for Economic Co-operation and Development countries with respect to cesarean deliveries. Breech presentation at term is an important indication for cesarean section among other factors, including medicolegal concerns and pregnancies in women of advanced maternal age. Term breech presentation is associated with a higher fetal mortality rate than that associated with a cephalic presentation. Therefore, in Korea, most of these women deliver by cesarean section to avoid the complications of vaginal breech delivery. However, cesarean section is itself associated with considerable obstetric morbidity and sometimes, mortality. External cephalic version (ECV) is a useful method to reduce the cesarean section rate in women with breech presentation and therefore to reduce the incidence of breech presentation at delivery. Studies have shown that routine use of ECV reduces the cesarean section rate by approximately two-thirds in term pregnancies with breech presentation. ECV is accepted as a safe, efficacious, and cost-effective method and is recommended by both the American College of Obstetricians and Gynecologists and the Royal College of Obstetricians and Gynecologists in all pregnancies with term breech presentation, if not contraindicated. In Korea, although most clinicians are aware of the option of ECV, their relative lack of experience in performing the procedure and fear of complications render them hesitant to perform ECV. This review is aimed at guiding obstetricians by describing the efficacy, safety concerns, and technical aspects of this procedure.

Success rate and influencing factors of external cephalic version for singleton pregnancies in the third trimester / 中华妇产科杂志

Objective To investigate the factors associated with the success rate of external cephalic version (ECV) for singleton and non-cephalic presentation pregnancies in the third trimester.Methods A retrospective study of ECV among singleton and non-cephalic presentation pregnant women in 36-40 weeks of gestation at Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region from January 2016 to June 2018 was analyzed.Results (1) Totally,251 cases of 358 pregnant women who underwent ECV were successful,with a total success rate of 70.1％ (251/358).The success rate of multipara was 79.1％ (129/163),while 62.6％ (122/195) in primipara (P＜0.01).The total vaginal delivery rate was 52.2％ (187/358),the vaginal delivery rate of multipara was 61.3％ (100/163),while 44.6％ (87/195) in primipara (P＜0.01).(2) Spontaneous reversion occurred in 7.6％(19/251) of ECV successful women,the rate of reversion of multipara was 10.9％ (14/129),higher than that of the primipara [4.1％ (5/122);P＜0.01].(3) Among the 232 pregnant women who did not reverted after successful ECV,187 cases of successful vaginal delivery,the vaginal delivery rate was 80.6％ (187/232);the vaginal delivery rate of the multipara was 87.0％(100/115),which was higher than that of the primipara [74.4％(87/117);P＜0.01].(4) The variables significantly associated with ECV success were parity,type of breech,whether fetal presentation was in pelvic or not (all P＜0.05).The complication rate was 2.2％ (8/358),among which the incidence of fetal distress,placental abruption and transient fetal heart abnormalities were 0.6％ (2/358),0.3％ (1/358) and 1.4％ (5/358) respectively.Conclusion By close monitoring,ECV is a safe and effective procedure in selected appropriate cases,and worthy of clinical application.

Cesarean section of breech presentation-the prevention of newborn fracture / 中国实用妇科与产科杂志

The breech presentation is a common occurrence in the obstetrical practice,accounting for about 3-5% of singleton fetuses at delivery.The Term Breech Trial demonstrated the planned cesarean section to be associated with a significant reduction in perinatal mortality and short term morbidity.Although the safety of cesarean section is widely reported,there is still a certain proportion of neonatal injuries,especially fracture.This paper focuses on the neonatal birth injury by cesarean section of breech presentation and the corresponding preventive measures and treatment,in order to reduce the newborn injury as much as possible.

Applying the newman-peacock prognostic system to a portuguese obstetrical population - A useful tool? / Utilização do modelo de prognóstico Newman-Peacock numa população obstétrica portuguesa - uma ferramenta útil?

Abstract Background External cephalic version (ECV) is a maneuver that enables the rotation of the non-cephalic fetus to a cephalic presentation. The Newman-Peacock (NP) index, which was proposed by Newman et al. in a study published in 1993, was described as a prediction tool of the success of this procedure; it was validated in a North-American population, and three prognostic groups were identified. Purpose To evaluate the value of the NP score for the prediction of a successful ECV in a Portuguese obstetrical population, and to evaluate maternal and fetal safety. Methods We present an observational study conducted from 1997-2016 with pregnant women at 36-38 weeks of pregnancy who were candidates for external cephalic version in our department. Demographic and obstetrical data were collected, including the parameters included in the NP index (parity, cervical dilatation, estimated fetal weight, placental location and fetal station). The calculation of the NP score was performed, and the percentages of success were compared among the three prognostic groups and with the original study by Newman et al. The performance of the score was determined using the Student t-test, the Chi-squared test, and a receiver operating characteristic (ROC) curve. Results In total, 337 women were included. The overall success rate was of 43.6%. The univariate analysis revealed that multiparity, posterior placentation and a less engaged fetus were factors that favored a successful maneuver (p < 0.05). Moreover, a higher amniotic fluid index was also a relevant predictive factor (p < 0.05). The Newman-Peacock score had a poorer performance in our population compared with that of the sample of the original study, but we still found a positive relationship between higher scores and higher prediction of success (p < 0.001). No fetal or maternal morbidities were registered. Conclusions The Newman-Peacock score had a poorer performance among our population compared to its performance in the original study, but the results suggest that this score is still a useful tool to guide our clinical practice and counsel the candidate regarding ECV.

Resumo Âmbito A versão cefálica externa (VCE) é uma manobra que permite a obtenção de uma apresentação cefálica em fetos não-cefálicos. O índice de Newman-Peacock (NP), proposto por Newman et al em um estudo publicado em 1993, foi descrito como preditivo do sucesso desta manobra; ele foi validado numa população norte-americana, e três grupos de prognóstico diferentes foram identificados. Objectivo Avaliação do valor preditivo do índice de NP para o sucesso da VCE numa população obstétrica portuguesa, bem como da segurança materno-fetal. Métodos Foi realizado no nosso departamento umestudo observacional entre 1997- 2016 em grávidas candidatas a VCE entre as 36 e as 38 semanas de gravidez. Foram colhidos dados demográficos e obstétricos, incluindo os parâmetros incluídos no índice de NP (a paridade, a dilatação cervical, a estimativa do peso fetal, a localização placentária e a altura da apresentação fetal). A pontuação das candidatas de acordo como índice de NP e a percentagemde sucesso da VCE foramcomparadas entre os três grupos de prognóstico, e também com o estudo original de Newman et al. O desempenho deste índice foi avaliado recorrendo aos testes t de Student, qui-quadrado e curva receiver operating characteristic (ROC). Resultados Foram incluídas 337 mulheres. A taxa de sucesso da manobra foi de 43,6%. A análise univariada mostrou que a multiparidade, a placentação posterior e uma apresentação não encravada foram favoráveis para o sucesso do procedimento (p < 0,05). Adicionalmente, um maior índice de líquido amniótico revelou-se também como um fator preditivo significativo (p < 0,05). O índice de Newman-Peacock apresentou um desempenho inferior na nossa população comparativamente à sua descrição original, porém continuou a verificar-se uma relação positiva entre pontuações mais elevadas e uma maior percentagem de sucesso (p < 0,001). Conclusão No nosso trabalho, o índice de Newman-Peacock apresentou um valor preditivo inferior comparativamente ao estudo original, porém os resultados mostram que se mantém uma ferramenta com utilidade para a prática clínica e para o aconselhamento das candidatas a versão cefálica externa.

[Objective] To investigate the safety and associated factor of external cephalic version (ECV) in third trimester,and to enrich clinical experience to improve the successful rate and lower cesarean section (CS) rate.[Methods] 80 pregnant women conducting ECV in third trimester in the third affiliated hospital of Sun Yat-sen University from September 2015 to July 2017 were enrolled in our study.Divided to successful group and failing group,we compared the clinical characters and pregnancy outcomes.[Results] Of the 80 pregnancy,48 women (60.0％) succeed with cephalic presentation.Compared to the failing group,the successful group is statistically different in parity,BMI and amniotic fluid depth.In the failing group,all women underwent CS with 3/48 in successful group.No women conducted ECV complicated fetal distress and emergency CS,premature rupture of membranes complicated in 11 (13.8％) cases in all women.[Conclusions] ECV is safe for mother and fetus.Encouraging the suitable pregnancy women to conduct ECV and enhancing clinical skills can improve ECV success rate.

External cephalic version without anaesthesia for breech presentation in singleton term pregnancies:a retrospective analysis of 195 cases / 中华围产医学杂志

Objective To investigate the safety and effectiveness of external cephalic version for breech presentation in singleton term pregnancies. Methods This study retrospectively analyzed the clinical data of 195 singleton pregnancies with gestational weeks ≥37 and breech presentation that has received external cephalic version in University of Hong Kong-Shenzhen Hospital from January 2014 to December 2016. The success rate of external cephalic version, delivery modes, maternal and neonatal complications and adverse outcomes were analyzed. Results Of the 195 cases, 62.6% (122/195) were successful, among which 107 vaginally delivered and 15 underwent the cesarean section. Maternal and neonatal outcomes of all 195 cases were good. The success rate of external cephalic version in the multipara was higher than that of the primipara [84.5%(71/84) vs 45.9%(51/111), χ2=30.383, P<0.001]. No neonatal asphyxiation or postpartum hemorrhage was reported. Conclusions External cephalic version is an effective and safe method to convert breech presentation and reduce cesarean section rate in the third trimester.

Evaluation of the learning curve for external cephalic version using cumulative sum analysis

OBJECTIVE: We evaluated the learning curve for external cephalic version (ECV) using learning curve-cumulative sum (LC-CUSUM) analysis. METHODS: This was a retrospective study involving 290 consecutive cases between October 2013 and March 2017. We evaluated the learning curve for ECV on nulli and over para 1 group using LC-CUSUM analysis on the assumption that 50% and 70% of ECV procedures succeeded by description a trend-line of quadratic function with reliable R² values. RESULTS: The overall success rate for ECV was 64.8% (188/290), while the success rate for nullipara and over para 1 groups was 56.2% (100/178) and 78.6% (88/112), respectively. ‘H’ value, that the actual failure rate does not differ from the acceptable failure rate, was −3.27 and −1.635 when considering ECV success rates of 50% and 70%, respectively. Consequently, in order to obtain a consistent 50% success rate, we would require 57 nullipara cases, and in order to obtain a consistent 70% success rate, we would require 130 nullipara cases. In contrast, 8 to 10 over para 1 cases would be required for an expected success rate of 50% and 70% on over para 1 group. CONCLUSION: Even a relatively inexperienced physician can experience success with multipara and after accumulating experience, they will manage nullipara cases. Further research is required for LC-CUSUM involving several practitioners instead of a single practitioner. This will lead to the gradual implementation of standard learning curve guidelines for ECV.

External cephalic version experiences in Korea

OBJECTIVE: The aim of this study was to evaluate obstetric outcomes of external cephalic version (ECV) performed at or near term. METHODS: Single pregnant woman with breech presentation at or near term (n=145), who experienced ECV by one obstetrician from November 2009 to July 2014 in our institution were included in the study. Maternal baseline characteristic and fetal ultrasonographic variables were checked before the procedure. After ECV, the delivery outcomes of the women were gathered. Variables affecting the success or failure of ECV were evaluated. RESULTS: Success rate of ECV was 71.0% (n=103). Four variables (parity, amniotic fluid index, fetal spine position and rotational direction) were observed to be in correlation with success or failure of ECV. In contactable 83 individuals experienced successful ECV, cesarean delivery rates were 18.1%, 28.9%, and 5.3% in total, nulliparas, and multiparas, respectively. CONCLUSION: Based on the results, ECV is proposed to be safe for both mother and her fetus. In addition, it is a valuable procedure that increases probability of vaginal delivery for women with breech presentation.

Evaluation of the Success Rate Following Amnioinfusion in Pregnant Women Undergoing External Cephalic Version after Initial Failure

PURPOSE: To evaluate the success rate following amnioinfusion in pregnant women undergoing external cephalic version (ECV) after initial failure. METHODS: This prospective study enrolled 17 consecutive pregnant women from October 2013 to May 2015. ECV was performed with amnioinfusion after initial failure. The success rates of ECV and vaginal delivery, including pregnancy outcomes, were analyzed. RESULTS: ECV was performed at an average of 37.3±0.6 weeks of gestational age. Eight of seventeen patients were nulliparous. The estimated fetal weight was 2,688±279 g, and the amniotic fluid index was 6.4±2.6 cm. The overall success rate of ECV was 70.6% (12/17), and the success rates in nulliparous and multiparous women were 75.0% (6/8) and 66.7% (6/9), respectively. The rate of emergent cesarean section within 24 hours was 11.8% (2/17). Excluding one women who were lost to follow-up, the rate of normal vaginal delivery was 81.8% (9/11) among the women who had successful ECV. We did not observe any complications such as uterine rupture, placental abruption, or intrauterine fetal death. CONCLUSION: Although ECV with amnioinfusion after initial failure might help increase the success rate of ECV, it needs to be further evaluated in larger studies.

Outcome of single breech term deliveries at the Federal Medical Centre, Owerri, South Eastern Nigeria: a five year review.

Background: The best mode of delivery of breech presentation for optimum neonatal outcome has been a subject of controversy over the years. Aim of current study was to determine the pattern of distribution, incidence, mode of delivery and outcome of singleton breech presentations at term among parturients at this centre. Methods: This was a retrospective study of singleton breech term delivery at the federal medical centre, Owerri between January 1, 2007 and December 31, 2011. Singleton breech term deliveries were identified from the labor ward register and the hospital numbers extracted to retrieve the case notes from the medical records department of the hospital. Some data were collected and analysed. Results: There were a total of 9624 deliveries during the study period, out of which 328 (3.4%) were singleton breech presentation at term. Term singleton breech was commoner in multiparous 200 (61%) than in primiparous 128 (39%) women. Extended (Frank) breech was the commonest type of breech presentation (60.4%) followed by flexed (complete) breech (36.0%) and footling breech (3.6%) was the least common. Assisted vaginal breech delivery was conducted in 66.2% of cases while 27.4% were delivered by emergency caesarean section and 6.4% of cases were delivered through elective caesarean section. There were one maternal and 24 perinatal death. Twenty one (87.5%) of perinatal deaths those occurred in unbooked mothers. Conclusion: Although assisted vaginal breech delivery for singleton breech term delivery was commonly performed in our centre, elective caesarean delivery gives the better neonatal outcome for fetuses presenting breech.

A Case Report on Female Pseudohermaphroditism: An Ambiguous Genitalia.

Ambiguous genitalia is a birth defect of the sex organs that makes it unclear whether an affected newborn is a girl or a boy. This condition occurs approximately 1 in every 4,500 births that causes gynecological and obstetrical problems. Defects of the external genital organs (penis, testes, or clitoris) usually result from abnormal levels of sex hormones in the fetus before birth. A 30-year-old primi with 38 weeks of pregnancy was admitted on August 21, 2011 at 8.45 PM with complaints of mild lower abdominal pain. Ultrasound scan on the same day showed a single 38 weeks live intrauterine fetus of ambiguous genitalia with breech presentation. Emergency lower segment cesarean section was performed on August 22, 2011 at 10.55 PM and the patient delivered a baby with ambiguous genitalia having both clitoris and penis. This diagnosed to be a case of female pseudohermaphroditism caused by congenital adrenal hyperplasia because babies who are born with ambiguous genitalia having external genital organs that do not appear clearly male or female or have features of both, but have female internal reproductive organs are known as female pseudohermaphrodities.
