Abstract
The rate of caesarean sections in multiple births has grown sharply worldwide. The reason for this may be the results of large retrospective cohort studies from the 1990s, which displayed an increased risk of mortality and morbidity, especially for the second twin, in the case of vaginal births. Multiple monocentric analyses have not been able to confirm this. As a prospective, multi-centre randomised study, the Twin Birth Study published in 2013, in which 105 clinics in 25 countries took part, showed that, under optimum conditions, there was no difference in neonatal and maternal mortality and morbidity if the birth was planned to be vaginal or via caesarean. Detailed analyses, which would be helpful in choosing the type of birth method and obstetric management in the event of vaginal birth, have not previously been published. Retrospective studies must be referred to for this.

[PMID: 22465994 PMCID: PMC3374120 DOI: 10.1007/s00404-012-2294-6] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2011] [Accepted: 03/06/2012] [Indexed: 12/03/2022]
Abstract
Purpose This systematic review aims to determine if there are evidence-based recommendations for the optimal mode of delivery for non-cephalic presenting first- and/or second twins. We investigated the impact of the mode of delivery on neonatal outcome for twin deliveries with (1) the first twin (twin A) in non-cephalic presentation, (2) the second (twin B) in non-cephalic presentation and (3) both twins in non-cephalic presentation. Methods A computer-aided search of Medline, Embase, Cinahl and Cochrane databases was carried out and quality of the studies was assessed with the Cochrane Collaboration’s tool for assessing risk of bias and the GRADE approach. Results One high-quality clinical trial (60 twin pairs) and 16 moderate/low-quality observational studies (3,167 twin pairs) showed no difference in neonatal outcome between vaginal and caesarean delivery in twin A and/or B. Conclusion Our results do not suggest benefit of caesarean over vaginal delivery for selected twin gestations with twin A and/or twin B in non-cephalic presentation. However, no final conclusion can be drawn due to the small sample sizes and statistic limitations of the included studies. Randomized studies with sufficient power are required to make a strong recommendation.

Abstract
AIM The first twin (T1) in breech position is at risk of complications during vaginal delivery, making the choice of the appropriate delivery route highly important. Although British and American practice guidelines recommend the cesarean section, the French National College of Obstetricians and Gynecologists concluded that there was not enough data to choose one delivery route or the other. In this context, we set out to describe practices in our centre. MATERIAL AND METHODS Our retrospective study was conducted at a level III labor ward between January 1st, 1995 and December 31st, 2006. One hundred and thirty-seven twin pregnancies at more than 26 gestational weeks (GW), with T1 in breech and T2 in any position, were included. RESULTS A cesarean section was performed before labor in 60.6 % cases. Among the 54 (39.4 %) cases where a trial of labor was accepted, 29 patients (53.7 % success rate) delivered vaginally and 25 (46.3 %) had a cesarean section during labor. No statistical difference was observed between the neonatal outcomes after cesarean section as compared to vaginal birth. However, a significant relationship was found between delivery route and parity. Less than one-third of nulliparas versus two-third of patients with a history of at least one delivery, having trials of labor, ultimately gave birth vaginally. Thus, we observed a high rate of cesarean section during labor in nulliparas (68 % of the initially accepted trials of labor). CONCLUSION Our study is the first one that clearly shows that the success rate of the trial of labor is closely related to a history of vaginal birth. Following these results and because of more than two-third of cesarean section during labor in nulliparas, we subsequently plan an elective cesarean section at the 38th GW for nulliparas with twin pregnancies and T1 in breech position. Nevertheless, if any of these patients go in labor before the cesearean section, a careful trial of labor is offered.

Abstract
OBJECTIVE In France, global rate of caesarian section in twin pregnancies has been 50.2% in 2003. Modes of delivery according to different twin presentations remain controversial in the literature. The purpose of our study is to analyze our practice of twin deliveries in a 5-year period, with neonatal outcomes. PATIENTS AND METHODS Among 22,243 women having delivered in our maternity (22 weeks and over) during the study period, the study population consisted of 371 twin pregnancies, of which 305 after 33 weeks gestation. RESULTS Different presentations were relatively identical whatever the gestational age of pregnancies: the "cephalic-cephalic" presentation represented 60 to 70% of the total, the "cephalic-breech" presentation approximately 10% while the "breech-cephalic" or "breech-breech" presentations approximately 8% each. Mean terms of pregnancies were 35.2 ± 2.8 weeks, mean birthweight being 2243 ± 561 g. C-section rate was 53.5%. When the first twin was in cephalic presentation, C-section rate was 40% while it was almost 100% when the first twin was in breech or "other" presentations. CONCLUSION There were no significant differences in neonatal outcomes (mean birthweights, Apgar scores, transfers in neonatology, perinatal deaths) according to different mode of deliveries (vaginal or C-sections). Our policy of planned cesarean section may need to be revised.

Abstract
OBJECTIVES To evaluate practices and perinatal outcome in planned routes of delivery for first breech twins. MATERIALS AND METHODS A retrospective study in first breech twin pregnancies with a gestational age of at least 35 weeks at onset of labor. Maternofetal pathologies known to be associated with a poor neonatal outcome were excluded. A low neonatal outcome was defined by at least one of the following criteria: neonatal death, 5-minute Agar Score < 7, cord blood pH < 7.10, traumatic neurological injuries, admission in neonatal intensive unit care. Neonatal and maternal outcomes were compared between attempt of vaginal delivery (AVD) and planned cesarean section (PCS). RESULTS Among 166 included patients, an AVD has been performed in 105 cases (63.3%) and a PCS in 61 (36.8%). In AVD group, 46 women (43.8%) delivered vaginally. Low neonatal outcome was not significantly different in AVD group compared with PCS group (9 (8.6%) versus 6 (9.8%); p = 0.78 for the first twin and 7 (6.7%) versus 2 (3.3%); p = 0.49 for the second twin). There was no significant difference in maternal morbidity between the two groups. As a general rule, established practices for deciding route of delivery and labor have been applied in our department. CONCLUSION No excess of neonatal risk in AVD group compared with PCS was observed. These results could be extrapolated to centers applying a careful protocol to decide the route of delivery and labor practices.

Abstract
OBJECTIVES To describe obstetrical policy variations concerning the delivery management in the case of twins, at term. PATIENTS AND METHODS A mail survey was undertaken among the medical supervisors of the maternity wards belonging to the AUDIPOG Network (N=170). RESULTS The participating rate was 73.35%. 124 answers were analysed. Elective caesarean was realized by 0.8% of participants for diamniotic twins and by 57% of cases for monamniotic twins An elective caesarean is planned for respectively 74% of answers if first (J1) and second twin (J2) are in a breech presentation, 81% if J1 is in breech and J2 in cephalic presentation, and 68% if J1 is in breech and J2 in transverse presentation. Delivery with J1 in breech and J2 in cephalic presentation had a higher risk than a delivery of a single breech at term. When J1 and J2 had a breech presentation 73% of participants thought that this delivery is more difficult than a delivery of a single breech at term. However, they were only 17.5% to consider that a delivery of twin with J1 in cephalic and J2 in breech presentation had a higher risk than a single breech delivery. DISCUSSION AND CONCLUSION Medical policy variations are not extensive except for X-ray pelvimetry and the presence for the delivery of one paediatrician and one anaesthesiologist. An elective caesarean policy for twins is infrequent in France.

Abstract
The aim of our study was to compare the neonatal outcome of vaginally delivered breech-presenting twins (VD) to those delivered by cesarean (CS). Maternal and neonatal charts of all live, non-anomalous twins delivered at > or =25 weeks of gestation, in a single tertiary care center, over an 11-year period were reviewed. Of 517 twins delivered, 130 breech-presenting twins were analyzed. Thirty-five (26.9%) were delivered vaginally and 95 (73.1%) by cesarean. More patients presented in labor with advanced cervical dilation in the VD compared to the CS group. There was no difference in the incidence of respiratory distress syndrome, intraventricular hemorrhage, need for mechanical ventilation, length of nursery stay or neonatal mortality rate when twin A was compared in the two groups. However, one breech-presenting twin in the VD group had a traumatic delivery at 32 weeks of gestation that caused a spine fracture followed by immediate neonatal death. Although there seems to be no compromise in the immediate neonatal outcome of breech-presenting twins delivered vaginally compared to those delivered by cesarean, the case of head entrapment that led to intrapartum death is quite alarming. Based on our study, we cannot advocate normal vaginal delivery when twin A is non-vertex: cesarean seems to be a safer route of delivery.

Abstract
Over the past several decades advances in assisted-reproductive technologies have resulted in a dramatic increase in the number of multifetal gestations. Concomitant with this increase there has been a gradual rise in the overall preterm birth rate, as well as other pregnancy complications related to these pregnancies. Twin, triplet, and other high-order multifetal gestation pregnancies pose a number of important issues related to antepartum and intrapartum management. Antepartum issues include ultrasound determination of zygosity, management and prevention of preterm labor, maternal/fetal surveillance for complications, and specific interventions focused on prevention of adverse maternal and/or fetal outcomes. Intrapartum issues include those related to timing of delivery, labor management, anesthesia options, and determination of an optimal delivery modality. Clearly, these issues related to the management of multifetal pregnancies are of paramount importance to optimize pregnancy outcome. As many of the issues related to antepartum care for women with multifetal gestations have been reviewed elsewhere, we have restricted the focus of this article to intrapartum management. Thus, this article reviews salient issues related to the intrapartum management of multifetal gestations, including twins, triplets, and other high-order pregnancies.

Abstract
OBJECTIVE We undertook a systematic review and meta-analysis to determine whether a policy of planned cesarean section or vaginal delivery is better for twins. STUDY DESIGN We searched MEDLINE and EMBASE from 1980 through May 2001 using combinations of the following terms: twin, delivery, cesarean section, vaginal birth, birth weight, and gestational age. Studies that compared planned cesarean section to planned vaginal birth for babies weighing at least 1500 g or reaching at least 32 weeks' gestation were included. We computed pooled odds ratios for perinatal or neonatal mortality, low 5-minute Apgar score, neonatal morbidity, and maternal morbidity. The infant was the unit of statistical analysis. Results were considered statistically significant if the 95% CI did not encompass 1.0. RESULTS We retrieved 67 articles, 63 of which were excluded. Four studies with a total of 1932 infants were included in the analysis. A low 5-minute Apgar score occurred less frequently in twins delivered by planned cesarean section (odds ratio, 0.47; 95% CI, 0.26-0.88) principally because of a reduction among twins if twin A was in breech position (odds ratio, 0.33; 95% CI, 0.17-0.65). Twins delivered by planned cesarean section spent significantly longer in the hospital (mean difference, 4.01 days; 95% CI, 0.73-7.28 days). There were no significant differences in perinatal or neonatal mortality, neonatal morbidity, or maternal morbidity. CONCLUSION Planned cesarean section may decrease the risk of a low 5-minute Apgar score, particularly if twin A is breech. Otherwise, there is no evidence to support planned cesarean section for twins.

Abstract
The delivery of twins presents considerable challenges to the obstetric team, particularly in terms of decision-making, technical skills required and the need to respond quickly to changing circumstances. There is a serious lack of sound evidence upon which to base decisions concerning the method of delivery of twins. The trend towards the routine use of caesarean section is not supported by evidence of improved outcome for the infants, while maternal outcome is compromised. Specific circumstances that may have a bearing on the need for caesarean section include gestational age, presentation of the twins and chorionicity/amnionicity. Caesarean section does not eliminate the chance of fetal trauma during delivery, particularly for premature twins. The techniques of twin delivery, whether vaginal or by caesarean section, require thorough preparation for all possible eventualities, and skilled teamwork. Particular attention should be paid to emotional needs during labour, birth and afterwards, of the parents of twins.
