Association of Persistent Breech Presentation With External Cephalic Version Success.
Obstetrics and gynecology, 2021Co-Authors: Roy Lauterbach, Gal Bachar, Chen Ben-david, Emad Matanes, Yuval Ginsberg, Ron Beloosesky, Nadir Ganem, Zeev Weiner, Yaniv ZiporiAbstract:OBJECTIVE To evaluate a possible correlation between a new variable-persistent Breech Presentation-and the success rate of external cephalic version (ECV). METHODS This was a retrospective study of ECVs performed from January 2008 through January 2019 in an Israeli tertiary care hospital. The study group included all pregnant women who underwent an ECV at or beyond 37 weeks of gestation. Persistent Breech Presentation was defined as persistent Breech Presentation during all ultrasound examinations performed between the anatomy scan at mid-pregnancy and the gestational week when ECV was attempted. Women in whom cephalic Presentation was documented at least once on these ultrasound examinations were defined as not having persistent Breech Presentation. The primary outcome was defined as the success rate of ECV, and the secondary outcome was defined as the mode of delivery after a successful ECV. RESULTS We identified 1,271 women with Breech Presentation during the study period. They had undergone median of five (range 2-7) ultrasound examinations. External cephalic version was attempted in 684 women (53.8%), with a success rate of 61.5%. External cephalic version succeeded in 19.6% of those with persistent Breech Presentation (44/224) compared with 82.0% (377/460) of those without persistent Breech Presentation (P

Perinatal mortality in Breech Presentation sibships
Obstetrics & Gynecology, 1998Co-Authors: Susanne Albrechtsen, Svein Rasmussen, Knut Dalaker, Lorentz M. IrgensAbstract:Abstract Objective: To compare perinatal mortality in Breech Presentation delivered vaginally and by cesarean in individual births and in sibships. Methods: A national, population registry–based study, 1967–1994, was conducted, with maternal record linkage of sibships, comprising the first to the third birth of a mother. The main outcome was perinatal mortality. Odds ratios of perinatal mortality were calculated and adjusted by logistic regression analysis. Results: The overall relative perinatal mortality was 4.3 (95% confidence interval [CI] 4.1, 4.5) in Breech compared with nonBreech Presentation and 5.4 (95% CI 4.7, 6.2) in vaginal compared with cesarean delivery. The relative perinatal mortality in Breech compared with nonBreech Presentation was lowest in birth order one compared with birth orders two and three. In Breech vaginal delivery compared with cesarean delivery, the opposite effect of birth order was found. The highest perinatal mortality was found in a current Breech Presentation of a sibship with no previous Breech births. In birth subsequent to Breech births, perinatal mortality was more or less independent of current Presentation, without respect to delivery method. The increased perinatal mortality in Breech Presentation is explained partly by its association with other risk factors for perinatal death. Conclusion: Women with recurring Breech Presentation represent a lower risk of adverse perinatal outcome. This might be explained by a biologic mechanism or by increased quality of antenatal care. An increased mortality in subsequent nonBreech siblings after a Breech Presentation was surprising.

Factors influencing delivery method in Breech Presentation
Acta obstetricia et gynecologica Scandinavica, 1998Co-Authors: Susanne Albrechtsen, Svein Rasmussen, Knut Dalaker, Lorentz M. IrgensAbstract:Background. To study factors influencing delivery method in Breech Presentation. Methods. Population based cohort study from The Medical Birth Registry of Norway, comprising all singleton deliveries in Norway, 1967-1994, 1,592,064 deliveries of which 45,921 (2.9%) were in Breech Presentation. Results. The proportion of cesarean section in Breech Presentation increased from 3.6 per 100 in 1969 to 58.8 in 1994. The relative risk for delivery by cesarean section in Breech Presentation compared to the nonBreech population increased from 2.0 (95% CI 1.5-2.7) in 1967 to 5.9 (95% CI 5.6-6.2) in 1994. It declined by maternal age, increased by gestational age and was lowest among mothers with urban residence. A negative association was observed between the annual number of births at the delivery department and the cesarean section proportion. However, during the observation period, the centralization of Breech deliveries to the largest departments was reduced. Conclusions. Vaginal delivery in Breech Presentation was particularly observed in large delivery departments and among mothers with urban residence. Since experience and practical competence are prerequisites for successful vaginal delivery, this centralization seems justified. Further centralization of all Breech Presentation births should be pursued. However, preparedness as to vaginal delivery should be established also at the smaller units, e.g. by a routine providing periodical centralized training for obstetricians working in smaller institutions.

The occurrence of Breech Presentation in Norway 1967‐1994
Acta obstetricia et gynecologica Scandinavica, 1998Co-Authors: Susanne Albrechtsen, Svein Rasmussen, Knut Dalaker, Lorentz M. IrgensAbstract:Background. To study the occurrence of Breech Presentation and its association with demographic and geographic variables. Method. Population based cohort study from the Medical Birth Registry of Norway comprising all singleton deliveries 1967-1994, a total of 1,592,064 deliveries. Of these, 45,921 in Breech Presentation. Results. From 1967 through 1994, the Breech Presentation proportion increased from 2.2%, (95% CI 2.1-2.3) to 3.4% (95% Cl 3.2-3.5). Breech Presentation was associated with high maternal age and low birth order, as well as low gestational age and birthweight. The secular trend was mainly due to demographic changes in terms of increasing proportions of births with low birth order and high maternal age. Breech Presentation was most frequent in urban areas. Conclusions. Strong associations were observed between Breech Presentation and low birth order as well as high maternal age. The findings are compatible with both intrinsic as well as environmental mechanisms. A full understanding of the birth order effect necessitates further studies based on sibship data. Prevention of premature delivery would be an effective measure for reducing the Breech Presentation proportion.

External cephalic version of Breech Presentation at term
Tidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin ny raekke, 2005Co-Authors: Susanne Albrechtsen, Lillian Nordbø Berge, Per E. Børdahl, Thore Egeland, Tore Henriksen, Lise Lund Håheim, Pål ØianAbstract:BACKGROUND External cephalic version could be an alternative to either vaginal delivery or caesarean section in Breech Presentation at term. MATERIAL AND METHODS A systematic literature review about external cephalic version in Breech Presentation. RESULTS The numbers of Breech Presentation delivered by caesarean section could probably be reduced in Norway by offering version, but this would not affect perinatal mortality.

Management of Breech Presentation at term: a retrospective cohort study of 10 years of experience
Journal of Perinatology, 2015Co-Authors: J Burgos, L Rodríguez, P Cobos, C Osuna, M Del Mar Centeno, R Larrieta, T Martínez-astorquiza, L Fernández-llebrezAbstract:Objective: To evaluate the impact of management of childbirth (external cephalic version (ECV) plus planned vaginal delivery (PVD)) of Breech Presentation at term (⩾37 weeks of gestation). Study Design: This retrospective cohort study was based on data collected of singleton Breech Presentations at term in the Obstetrics and Gynaecology Service, Cruces University Hospital (Biscay, Spain), from January 2003 to December 2012. Result: We attended 2377 singleton Breech pregnancies at term. We attended 1684 singleton Breech term deliveries, attempting vaginal delivery after selection in 52.9% of cases and were successful in 57.5% of attempts. A total of 1360 ECV were attempted, with a success rate of 50.3% of those attempted. The use of ECV has decreased the rate of Breech Presentation at delivery by 39.0%, the rate of Breech Presentation as a caesarean section (CS) indication by 47.1% (CS due to Breech Presentation/total of CS) and the rate of CS for Breech Presentation out of the total of deliveries by 39.1% (CS due to Breech Presentation/total of deliveries). Early postnatal parameters (5-min Apgar score, umbilical cord arterial pH and acid-base analysis) were significantly lower following PVD compared with planned CS for Breech Presentation. However, we did not find any differences in the rates of admissions to the neonatal unit or neonatal mortality. Conclusion: Management of Breech Presentation with a protocol that includes ECV, careful selection criteria and active management of vaginal delivery achieve a great decrease in the rate of CS for Breech Presentation.
