Vaginal Delivery Of Twins Research Articles

Review of Twin Pregnancies in a Tertiary Hospital in Abuja, Nigeria

Studies on twin pregnancy are uniquely important to Africa and particularly Nigeria where the highest incidence in the world exists. This study was designed to determine the trend, rate, and obstetric outcomes of twin deliveries in the University of Abuja Teaching Hospital, Gwagwalada. This was a retrospective study of twin deliveries in the hospital over a period of 10 years. During the study period, there were 349 twin births out of 10,739 deliveries, giving an overall twining rate of 32.5 per 1,000 deliveries. Preterm delivery occurred in 39.7% cases and was, therefore, the most common complication. Mode of delivery was vaginal in 72.7% while 27.3% were delivered by caesarean section. Emergency caesarean section for delivery of both the babies was carried out in 22.3% while elective caesarean section for both the babies accounted for 1.0%. Combined vaginal and abdominal delivery occurred in 4.0% of deliveries. The stillbirth rate was 102 per 1,000 births. There were 24 (8.0%) and 37 (12.3%) stillbirths among the first and the second baby respectively. The mean foetal weight was 2.395 +/- 0.63 kg while the female-to-male ratio was 1:1.1. The rate of twin deliveries in our centre is high. Successful vaginal delivery of twins is high when the mothers are booked and the presentations of the twins are favourable. The use of antenatal care services and good intrapartum management will help improve outcome in twin pregnancies.

Maternal Coagulopathy After Umbilical Cord Occlusion for Twin Reversed Arterial Perfusion Sequence

Twin reversed arterial perfusion sequence is a rare complication of monochorionic twin gestations for which therapy involves the disruption of vascular anastomoses between the pump twin and acardiac twin and death of the acardius. A 37-year-old woman, gravida 11 para 2, with a monochorionic twin pregnancy complicated by twin reversed arterial perfusion sequence who underwent umbilical cord occlusion at 24 weeks of gestation was admitted in preterm labor at 33 weeks of gestation. Maternal disseminated intravascular coagulation (DIC) was diagnosed and her labor was induced. She received multiple blood products to correct her coagulopathy and had an uncomplicated vaginal delivery of the viable pump twin. Maternal DIC may complicate fetal death after umbilical cord occlusion.

Cesarean Section for the Second Twin: A Population‐Based Study of Occurrence and Outcome

Although management of twin deliveries has been a topic of discussion for decades, a consensus on how to deliver twins is lacking. The objective of this study was to examine short-term neonatal outcome of the second twin delivered by cesarean section after vaginal delivery of the first-born twin (combined delivery) and to identify predictors of combined delivery. This study was a 3-year, population-based, retrospective cohort investigation of 1,254 twin births in Denmark. The twin births were divided into three groups: vaginal deliveries, planned cesarean deliveries, and combined deliveries. Data were extracted from medical records, a fetal medicine software program (Astraia), and the National Birth Registry. Short-term poor neonatal outcome was measured as a 5-minute Apgar score ≤ 7, umbilical cord pH ≤ 7.10, and admission to neonatal intensive care unit for more than 3 days. Vertex-nonvertex fetal presentations were more prevalent in combined deliveries than vaginal deliveries (OR 4.4, 2.5-7.8). Nonvertex second twins born by combined delivery had a higher risk of Apgar score ≤ 7 and umbilical cord pH ≤ 7.10 compared with vaginal delivery, unadjusted OR 6.2 (2.1-18), and unadjusted OR 3.9 (1.6-9.5). Prenatal ultrasound scans were evaluated in combined deliveries, of which 48 percent were vertex-vertex at the last ultrasound scan in pregnancy (mean gestational age 34 + 0) and 37 percent were vertex-vertex at birth. Vertex-nonvertex presenting twins have an increased risk of combined delivery. Combined deliveries are associated with increased neonatal morbidity for the second twin.

Pregnancy outcome and factors affecting vaginal delivery of twins at University of Nigeria Teaching Hospital, Enugu

The study aims to determine the differences in maternal and perinatal outcomes between caesarean and vaginal deliveries and the factors affecting vaginal delivery in twin pregnancy. An observational study to audit twin pregnancies delivered at the University of Nigeria Teaching Hospital between 2002 and 2008. Clinical observations were entered into a questionnaire immediately after the delivery of the women and the mothers and their babies were followed up until the end of the puerperium. There were 5298 deliveries within the study period, out of which 117 were twin deliveries. This gives a twinning rate of 22 per 1000 deliveries. The mean age of the mothers was 30 ± 5.9 years. Twenty-five (21.4%) women were admitted into the hospital for preterm labor. The average gestational age of admission was 32 ± 5.8 weeks and the average duration of hospital stay for preterm labor was 12.6 ± 9.1 days. Other pregnancy complications observed were severe hypertension (14.5%, anemia (9.4%), postpartum hemorrhage (8.5%), puerperal fever (5.1%), abruptio placentae, and diabetic mellitus (2.7%). Fifty-nine women (50.4%) had vaginal deliveries, 5 (4.3%) had vaginal delivery of the leading twin and caesarean delivery of the retained second twin while 53 women (45.3%) were delivered by caesarean section. Forty-eight (41%) women had preterm delivery. Vaginal deliveries were more common than caesarean section among patients that were unbooked than booked P = 0.047 (OR 2.26, 95%CI:0.93-5.53) and those that had cephalic presentation of the leading twin, P = 0.0002 (OR = 4.7 95% CI:2.6-8.2). Vaginal delivery tended toward statistical significance when the fetal weight of the leading twin was 1.5 to 2.5 kg, P = 0.09. The commonest indications for caesarean section were abnormal lies and presentations and hypertension in pregnancy.Two-hundred and seventeen (92.7%) out of a total of 234 fetuses that were delivered in this study were live births and 17 (7.3%) still births. The rate of new born admissions in twin 1 was however higher in those delivered by Caesarean section (39.6%) than those delivered vaginally (29.7%). Indications for admissions into the special baby care units were; prematurity 33 (40.2%), birth asphyxia 15 (18.3%), low birth weight 12 (14.6%), neonatal jaundice 10 (12.2%), and twin-twin transfusion 4 (4.9%). There was a higher rate of early neonatal death in both vaginally delivered twin 1 (9.4%) and twin 2 (11.9%) than those delivered by Caesarean section, 3.8 and 3.5%, respectively. Cephalic presentation of the leading twin, birth weight less than 2.5 kg, and unbooked women presenting in advanced labor predisposed to vaginal delivery in twin pregnancies. There was however increased risk of still birth and early neonatal deaths especially for the leading twin in vaginal deliveries in unbooked women.

689: Risk factors predicting an emergency cesarean section for second twin after vaginal delivery of the first twin

To investigate obstetrical risk factors predicting an emergency cesarean section (CS) for the second twin after vaginal delivery of the first twin. In addition, the study was aimed to define perinatal outcomes of the second twin.

Influence of chorionicity in intra-partum management of twin deliveries

Objective: To analyze morbidity and mortality in twin pregnancies as a function of the type of delivery and chorionicity. Design: Retrospective cohort study. Methods: Analysis of the type of delivery, intertwin time interval, and perinatal variables of >1000 twin deliveries during a 10-year period. Main outcome measure: Influence of delivery type and chorionicity on perinatal outcome. Results: The rate of cesarean sections was 42.4%. No differences were found as a function of chorionicity or as a function of presentation of the second twin. Cesarean sections were performed after vaginal delivery of the first twin in 1.8% of cases, being more common if the second baby was in a non-cephalic presentation (6.9% vs. 0.4%, p < 0.05). The average twin-to-twin delivery time interval was longer in the cases where the second had a cephalic presentation (8.26 ± 7.75 min vs. 6.81 ± 5.97 min, p < 0.05). The umbilical artery pH was lower the longer the interval between the birth of the twins, both in monochorionic and dichorionic. Conclusions: According to the results, vaginal delivery is as safe as elective caesarean section in twin pregnancies where the first twin is in cephalic presentation and the intrapartum management should not vary due to chorionicity.

Obstetric anal sphincter injuries in vaginal delivery of twins: associated risk factors and comparison with singletons

Risk factors related to obstetric anal sphincter injuries (OASIS) are known for singleton deliveries. No study to date has described the rate and risk factors involved in twin deliveries. We conducted a retrospective cohort study (1985-2010) of all vaginal twin and singleton deliveries in a single tertiary center. The adjusted odds ratio (OR) for OASIS at delivery was estimated using the logistic regression model. The study comprised 1,538 and 91,312 patients with vaginal twin and singleton delivery, respectively. Twenty twin (1.27 %) and 2,331 (2.55 %) singleton deliveries were complicated with OASIS. The following OASIS-associated risk factors were shared by both populations: nulliparity [twins adjusted OR 5.9, 95 % confidence interval (CI) 1.7-20.9; singletons adjusted OR 3.9, 95 % CI 3.5-4.4), occipitoposterior (OP) position (twins adjusted OR 3.00, 95 % CI 1.1-8.0; singletons adjusted OR 1.6, 95 % CI 1.3-2.00), birthweight (for each 100 g) (twin adjusted OR 1.1, 95 % CI 1.0-1.2; singletons adjusted OR 1.07, 95 % CI 1.06-1.08), and instrumental delivery (twins adjusted OR 4.3, 95 % CI 1.2-15.4, singletons adjusted OR 2.4, 95 % CI 2.2-2.6). Risk factors of nulliparity, OP position, large fetal size, and instrumental delivery were shared by both twin and singleton deliveries. These data will be useful in counselling women carrying twins who intend to deliver vaginally.

Term pregnancy with umbilical cord prolapse

ObjectiveTo investigate the incidence, management, and perinatal and long-term outcomes of term pregnancies with umbilical cord prolapse (UCP) at Mackay Memorial Hospital, Taipei, from 1998 to 2007. Materials and MethodsFor this retrospective study, we reviewed the charts, searched a computerized birth database, and contacted the families by telephone to acquire additional follow-up information. ResultsA total of 40 cases of UCP were identified among 40,827 term deliveries, an incidence of 0.1%. Twenty-six cases (65%) were delivered by emergency cesarean section (CS). Of the neonates, 18 had an Apgar score of <7 at 1 minute, 10 of these scores being sustained at 5 minutes after birth, and three infants finally died. Eleven UCPs occurred at the vaginal delivery of a second twin, and nine with malpresentation. All of the infants who had good perinatal outcomes also had good long-term outcomes. Poor perinatal outcomes occurred in cases where there was a delayed diagnosis, or an inability to carry out an emergency CS or a prompt vaginal delivery. ConclusionEarly detection of UCP and expeditious delivery are crucial to good perinatal outcomes. An emergency CS remains the mainstream management. Multiparous women whose cervixes are nearly fully dilated and who are expecting babies relatively smaller than their elder brothers or sisters born vaginally may still have vaginal deliveries managed by well-experienced birth teams, with good perinatal outcomes. Otherwise, vaginal delivery is not recommended and CS is the wiser choice.

Meckel-Gruber Syndrome (Dysencephalia Splanchnocystica)

Meckel-Gruber syndrome is a rare lethal autosomal recessive condition which was first described by Johann Friedrich Meckel in 1822 and GB Gruber in 1934. More than 200 cases have been reported worldwide with an incidence ranging from 1:13,250 to 1:140,000 live births. A 21-year-old female with G3 A2 L0, presented with twin pregnancy with history of previous two anencephalic pregnancies. The present pregnancy was a preterm vaginal delivery of female twins by face presentation at 35 weeks of gestation (diamniotic dichorionic twin gestation). Neonatal autopsy revealed classical triad of occipital encephalocele, polycystic kidneys and lungs with postaxial polydactyly. This case is presented for its rarity and its documented occurrence in Gujarati Indians.

Twin-to-Twin Delivery Time: Neonatal Outcome of the Second Twin

To examine the effect of twin-to-twin delivery time (TTDT) on neonatal outcome. We evaluated twin deliveries >34 weeks of gestation. Twin pregnancies with both twins delivered by cesarean section and pregnancies with antenatal complications were excluded. We analyzed TTDT and neonatal outcomes of the second twin (umbilical arterial pH value (pH(art)), Apgar scores at 1, 5 and 10 minutes, need for intensive care). The study population was divided into two homogenous groups based on the mode of delivery: (A) vertex presentation and vaginal delivery of both twins, (B) vertex presentation and vaginal or vaginal operative delivery of twin I, breech or transverse presentation and vaginal breech delivery or cesarean section (CS) of twin II. A total of 207 twin pairs were included in our study. In Group A (n = 151) there were no significant correlations between TTDT and pH(art) or Apgar scores at 1,5 and 10 minutes of twin II (p = .156; 0.861; 0.151 and 0.384, respectively). In Group B (n = 56), the mean pH(art) of twin II was inversely correlated to TTDT, but not significantly (p = .417). TTDT was inversely related to 1-min and 5-min Apgar scores, but not significantly (p = .330; p = .138, respectively). The 10-min Apgar score showed no correlation with TTDT (p = .638). Increasing TTDT was not associated with adverse fetal outcome. Expectant management of the second twin appears possible and elapsed time alone does not appear to be an indication for intervention.

The use of thromboelastography for the peripartum management of a patient with platelet storage pool disorder

We describe the peripartum management of a 26-year-old primigravida with a platelet storage pool disorder who underwent spontaneous vaginal delivery of twins with epidural analgesia. Postpartum hemorrhage from uterine atony, and cervical and vaginal lacerations were treated successfully with 1-desamino-8D-arginine vasopressin and blood products. The use of thromboelastography in the assessment and management of bleeding risk in the setting of platelet storage pool disorder is described.

Geburtsleitung bei dichorialen Zwillingen am Termin bei vorangehendem Zwilling in Schädellage – eine monozentrische retrospektive Kohortenstudie

To assess neonatal outcome and delivery mode in dichorionic twin delivery at term with a cephalic-presenting first twin. A retrospective cohort study of 308 twin deliveries after 37 completed weeks of gestation with a cephalic-presenting first twin undertaken in one perinatal center with active management of second twin delivery. The neonatal outcome was measured by the Apgar score, the umbilical artery pH and the transfer into the neonatal unit. In the whole group, 57% were vaginally delivered and 43% needed a Cesarean delivery. The planned vaginal delivery group contained 71% while the planned elective Cesarean delivery group contained 29%. In the planned vaginal delivery group 80% were delivered vaginally, in 15% an emergency Cesarean was necessary, 5% had a vaginal delivery of the first twin followed by Cesarean delivery of the second twin. The neonatal outcome of the second twin shows a higher risk. There are significant differences in the rates of the second twin having lower rates of the umbilical artery pH >7.20 in the group of planned vaginal delivery. The higher risks are compensated in the group of planned elective Cesarean delivery. Planned vaginal delivery of dichorionic twins at term and active second-stage management is associated with lower rate of normal neonatal outcome. These risks should be considered in prenatal informed consent discussions with the pregnant woman.
