Abstract
OBJECTIVES This study aimed to assess the value of prophylactic cervical cerclage in prolonging higher-order multiple pregnancies. METHODS This retrospective study included all women with higher-order multiple pregnancies beyond 24 gestational weeks treated at the King Abdullah University Hospital in Irbid, Jordan, and King Fahad Medical City in Riyadh, Saudi Arabia, between February 2014 and January 2015. Selected maternal characteristics and obstetric outcomes were compared between women who received prophylactic cervical cerclage and those who did not. RESULTS A total of 146 women with higher-order multiple pregnancies were included in the study; of these, 94 (64.4%) underwent a prophylactic cervical cerclage insertion procedure and 52 (35.6%) women did not. No significant difference was found between the two groups with regards to maternal age, parity or number of fetuses. However, the mean gestational age at delivery was significantly higher for women without compared to those with prophylactic cervical cerclage (32.9 weeks versus 31.7 weeks) according to both univariate and multivariate analyses (P = 0.013 and 0.046, respectively). Additionally, 40.4% of women without and 14.9% of women with prophylactic cervical cerclage gave birth after 34 gestational weeks (P = 0.003). CONCLUSION Overall, prophylactic cervical cerclage was not associated with prolongation of the pregnancy among women with higher-order multiple pregnancies in the current study.

Abstract
OBJECTIVE We sought to determine the interventions utilized by maternal-fetal medicine specialists in the prediction and prevention of preterm labor in higher-order multiple (HOM) gestations. STUDY DESIGN Online questionnaires and email surveys were sent to all the maternal-fetal medicine specialists in Canada (n=122). Questionnaire items included interventions physicians routinely recommended for HOM gestations including: (1) bed rest; (2) cervical length measurement on transvaginal ultrasound; (3) corticosteroids use; (4) cerclage; and (5) tocolytic therapy. RESULTS Response rate was 66% (81/122), with 68% of respondents in practice for >10 years. Of physicians, 91% did not routinely recommend bed rest (95% confidence interval [CI], 84.7-97.2). In all, 82% (95% CI, 73.63-90.4%) recommended routine cervical length assessment with 32.3% (95% CI, 20.7-43.2) and 37.1% (95% CI, 25.3-48.6) of this group suggesting assessment at 16-18 and 19-21 weeks, respectively. Frequency of assessment varied from biweekly (53.3%; 95% CI, 40.9-65.0), to monthly (23.3%; 95% CI, 12.8-33.1), to a single measurement repeated only if abnormal (12.5%; 95% CI, 4.5-20.8). In all, 28% (95% CI, 18.2-37.8) recommended routine administration of corticosteroids for lung maturation. Timing of administration varied, with 24% initiating steroids between 24-26 weeks, 59% between 27-28 weeks, and 17% after 28 weeks. None reported routine cerclage placement. However, 71% (95% CI, 61.1-80.8) would perform cerclage based on history or ultrasound. Of respondents, 81% (95% CI, 72.4-89.5) would consider using tocolytic agents for threatened preterm labor including calcium channel blockers (94%), nonsteroidal antiinflammatory drugs (5%), and nitroglycerin transdermal patch (24%). CONCLUSION The variable practice guidelines and paucity of data for management of HOM pregnancy places the onus on individual practitioners to develop their own management schemes. This results in heterogeneous management, which is based on conflicting international guidelines, studies, expert opinion, or past experience.

Abstract
BACKGROUND The incidence of multiple pregnancies is increasing with the availability of assisted reproductive techniques. Preterm labor and preterm rupture of membranes are major complications in such pregnancies. Preterm delivery of the first fetus is often followed by delivery of the remaining fetuses. However, conservative management in such circumstances might allow for fetal lung maturity in the remaining fetuses. CASE We present a case of conservative management of an in vitro-fertilized triplet pregnancy with early loss of the leading triplet. A 33-year-old woman in the 21st week of a triplet pregnancy delivered her one of the fetuses, 4 days after the preterm rupture of membranes. To save the surviving fetuses, ligation of the umbilical cord at the cervical level was performed. Patient received antibiotics, tocolytics and corticosteroids after then. The second and the third fetuses were successfully delivered by cesarean section in the 28th week of pregnancy, 43 days after the first fetus was born. CONCLUSION We can improve the life expectancy of the retained fetuses by conservative management using tocolytics, antenatal steroids to stimulate lung maturation and antibiotics following the delivery of the first fetus.

Abstract
OBJECTIVE The purpose of this study was to determine if routine prophylactic cervical cerclage was associated with a significant prolongation of triplet pregnancy. STUDY DESIGN A retrospective study of all women carrying triplet pregnancies at a single institution during a four-year period was carried out. Selected maternal characteristics and obstetric outcome measures in women who received prophylactic cerclage (PC) were compared to women who did not receive PC (no cerclage placed and emergency cerclage). Statistical comparison was done using the Mann-Whitney test for continuous variables and Fisher's exact test for categorical variables. RESULTS Fifty-five women had PC and 40 had no PC. There was no significant difference between these two groups in mean maternal age or weight, nulliparity, history of or current sexually transmitted disease, cigarette smoking, history of cervical insufficiency, prior dilation and curettage, prior cervical surgery, prior preterm labor/prolonged preterm rupture of membranes (PTL/PPROM), medical complications in pregnancy, current PTL/PPROM, gestational age at delivery, delivery prior to 28 weeks, delivery prior to 32 weeks, or delivery of an infant weighing less than 1000 or 1500 grams. Thirteen women in the no PC group (32.5%) required emergency cerclage. CONCLUSION PC was not associated with significant prolongation of triplet pregnancy.

Abstract
This paper reviews the patterns of occurrence, measurement and the effect of birth weight discordance on fetal and neonatal mortality in multiple pregnancies (twins and triplets). Birth weight discordance is fairly common among multiple pregnancies, and about one-quarter of the twin deliveries are affected by a birth weight discordance of 15%, while nearly 5% of twin gestations experience severe discordance (>or= 35%). Factors influencing birth weight discordance are exaggerated in triplet deliveries. Approximately 20% of triplet sets experience a birth weight discordance of 25 - 35% and nearly 10% experience severe forms of discordance. Frequencies of discordant sets at >25% discordance along the range of birth weight deciles show an inverse logarithmic relationship in twins, while the best-fit function in triplets is polynomial. Birth weight discordance is significantly associated with both fetal and neonatal mortality. Neonatal demise among the severely discordant smaller twin is significantly more frequent than in a non-discordant smaller twin. The magnitude of the effect is greater when one or both of the discordant twins are concomitantly small for gestational age.

Abstract
BACKGROUND The management of delayed delivery in a triplet pregnancy is described. CASE A 25-year-old woman with an in vitro fertilization pregnancy aborted the presenting fetus at 19th gestational week. As she decided to carry on, cervical cerclage, tocolysis and antimicrobial prophylaxis were performed. The remaining fetuses survived until 29th gestational week. CONCLUSION Prolongation of multiple pregnancies after the abortion of presenting fetuses is a possible approach, which is especially justified in women with a history of infertility.

Abstract
OBJECTIVE To create ultrasound growth curves for normal growth of fetal triplets using statistical methodology that properly accounts for similarities of growth of fetuses within a mother as well as repeated measurements over time for each fetus. METHODS In this longitudinal study, all triplet pregnancies managed at a single tertiary center from 1992-2004 were reviewed. Fetuses with major anomalies, prior selective reduction, or fetal demise were excluded. Data from early and late gestation in which there were fewer than 30 fetal measurements available for analysis were excluded. We used multilevel models to account for variation in growth within a single fetus over time, variations in growth between multiple fetuses within a single mother, and variations in fetal growth between mothers. Medians (50th), 10th, and 90th percentiles were estimated by the creation of multiple quadratic growth models from bootstrap samples adapting a previously published method to compute prediction intervals. Estimated fetal weight was derived from Hadlock's formula. RESULTS One hundred fifty triplet pregnancies were identified. Twenty-seven pregnancies were excluded for the following reasons: missing records (23), fetal demise (3), and fetal anomaly (1). The study group consisted of 123 pregnancies. The gestational age range was restricted to 14-34 weeks. Figures and tables were developed showing medians, 10th and 90th percentiles for estimated fetal weight, femur length, biparietal diameter, abdominal circumference, and head circumference. CONCLUSION Growth curves for triplet pregnancies were derived. These may be useful for identification of abnormal growth in triplet fetuses. LEVEL OF EVIDENCE III.

Abstract
OBJECTIVE The purpose of this study was to determine if prophylactic cerclage improves pregnancy outcome in women with triplet pregnancies without a history of cervical insufficiency. STUDY DESIGN Triplet pregnancies with > or = 1 day of outpatient surveillance beginning before 32 weeks' gestation were identified from a database of women in the US who received outpatient preterm labor surveillance services between January 1990 and May 2004. Triplet pregnancies managed with prophylactic cerclage were compared with triplet pregnancies in which cerclage was not placed. Patients with a diagnosis of cervical insufficiency in a previous or in the index pregnancy were excluded from analysis. The primary outcome was incidence of preterm birth before 32 weeks. Groups were compared using Fisher exact test, and Student t test with 2-sided P values < .05 considered statistically significant. RESULTS Three thousand two hundred seventy-eight triplet pregnancies met criteria for inclusion, of which 248 women (7.6%) received prophylactic cerclage. No significant differences were seen in mean gestational age at delivery, incidence of preterm birth before 32 weeks, birth weight, or neonatal days in the hospital. This study had 80% power to detect a 30% reduction in the primary outcome. CONCLUSION Prophylactic cerclage did not result in improved pregnancy or neonatal outcomes in triplet pregnancies without a history of cervical insufficiency.

Abstract
High-order multiple gestation presents unique challenges to the clinician to obtain the best possible outcome. An aggressive proactive approach works best compared with a wait-and-treat strategy when complications occur. Frequent ultrasound evaluations, fetal fibronectin testing, and contraction monitoring are important diagnostic tools. Aggressive weight gain, bed rest, and relaxation techniques are important interventions. Tocolytic drugs are used to prevent preterm labor, and aggressive dosing of MgSO4, terbutaline pumps, and oral agents are advocated to treat preterm labor. Outcome is generally good with high-order multiple gestation with this management protocol.

Abstract
Aims: It is well documented that maternal morbidity and neonatal morbidity and mortality increase alike in high-order multiple (HOM) births. There have, however, been few reports concerning the costs of maternal and neonatal medical care associated with HOM births. This is the first such report on the situation in Japan. Materials and methods: All triplet and quadruplet pregnancies managed at this institution from before 16 weeks' gestation, and delivered at no earlier than 22 weeks' gestation, between 1997 and 2002 were included. Prophylactic cervical ligature, hospitalization to prevent premature labor from 23 weeks' gestation until delivery, and delivery by cesarean section, were all routine for HOM pregnancies. All women with singleton and twin pregnancies, who underwent in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) and also delivered their babies at no earlier than 22 weeks' gestation at this institution, between 1997 and 2002, were also examined as controls. Prophylactic cervical ligature, preventive hospitalization, and cesarean section were not routine in the control group. Results: The average gestational ages at delivery in singleton (n = 58), twin (n = 21), triplet (n = 14) and quadruplet (n = 1) pregnancies, were 39.4, 35.6, 31.9 and 25.1 weeks, respectively (P < 0.001 by anova). Birthweights were 2886 ± 425 g, 2117 ± 623 g, 1430 ± 373 g, and 633 ± 77 g (mean ± SD), respectively (P < 0.001). The average inpatient medical care cost for mother and child(ren), from maternal admissions after 12 weeks' gestation to the discharge of all family members from hospital, was ¥703 279 yen (∼US$5861), ¥4 903 270 (∼US$40 861), ¥11 810 327 (∼US$98 419), and ¥44 961 000 (∼US$374 675), respectively (P < 0.001). Conclusion: The present study outlined the high costs of medical care for HOM pregnancies. Not only from a medical viewpoint, but also from the viewpoint of medical costs, it is important to avoid HOM pregnancies as a result of infertility treatment. (Reprod Med Biol 2004; 3: 159-164).

Abstract
The aim of the study was to examine the ponderal index in small for gestational age (SGA) triplets. Prospectively collected data from a cohort of triplets born at 28 to 37 weeks were analyzed. A low neonatal ponderal index (birth weight/[length]3) was defined as less than 1 SD below the mean (2.0), and SGA was considered as birth weight below the 10th percentile by triplet standards. We studied 2181 sets of triplets. Triplets delivered at < or = 33 weeks have a lower mean ponderal index compared with those delivered at > 33 weeks. About 70% of SGA triplets do not have a low ponderal index, whereas 79.2% of infants with a low ponderal index are not SGA by triplet standards. Both the frequency of a low ponderal index and the frequency of infants with a low ponderal index who are not SGA decrease with increasing gestational age. We conclude that the majority of triplets with a low ponderal index might not be considered growth restricted, supporting the concept that reduced fetal weight of triplets is more likely a physiological rather than a pathological phenomenon.

Abstract
Cervical incompetence causes repeated mid-trimester miscarriage and preterm delivery with high fetal wastage. Since the introduction of cervical cerclage in 1951, it has undergone many changes with regard to the techniques, indications and postoperative care. The objective of this study is to review the changing trends in the current indications of cervical cerclage and subsequent perinatal outcome at the maternity hospital from January 1992 to December 1999. All the files of women who had had cervical cerclage were evaluated in terms of characteristics of the women, indications and obstetric outcome after cervical cerclage. Of 65539 who delivered in the hospital, 1021 women had had cervical cerclage, giving an incidence of 1.21%. There was a significant increase in the incidence of cervical cerclage, from 1.13% in 1992 to 1.40% in 1999 (P < 0.01). More women with multiple pregnancy in 1996 - 99 had cerclage than in 1992 - 94 period [22.7 vs. 8.5% (P < 0.01)]. It is clear that more cervical sutures are being performed in multiple pregnancies arising from assisted reproductive technology as well as after ultrasonographic evidence of cervical dilatation. A multicentre randomised clinical trial is therefore advocated to evaluate its effectiveness in these cases.

Abstract
OBJECTIVE To examine whether cervical cerclage after the first delivery prolongs the inter-delivery interval in delayed interval deliveries. STUDY DESIGN We identified 66 case reports and case series of delayed interval delivery published between 1880 and 2002. We selected seven case series that identified all cases of delayed interval delivery in their institutions during a specified period. RESULTS Despite routine use of broad-spectrum prophylactic antibiotics, the average incidence of clinical intrauterine infection after the first delivery was 36% (95% confidence interval (CI): 26-46%). The incidence of maternal sepsis was 4.9% (95% CI: 0.2-9.6%). Studies in which cerclage was infrequently used reported a shorter inter-delivery interval compared to studies where cerclage was used in all cases (median is equal to 9 days versus 26 days, respectively, P<0.001) despite similar gestational ages at the first delivery, types of antibiotics, tocolytics, and incidence of infection. After controlling for other factors, the use of cerclage did not significantly increase the risk of intrauterine infection (adjusted relative risk=1.1, 95% CI: 0.4-3.5). CONCLUSION Cervical cerclage after the first delivery is associated with a longer inter-delivery interval without increasing the risk of intrauterine infection.

Abstract
Cervical incompetence is defined as the inability to support a full-term pregnancy because of a functional or structural defect of the cervix. It is characterized clinically by acute, painless dilatation of the cervix usually in the mid-trimester culminating in prolapse and/or premature rupture of the membranes with resultant preterm and often previable delivery. Cervical cerclage has become the mainstay for the management of cervical incompetence, but remains one the more controversial surgical interventions in obstetrics. This article reviews the current state of the literature as regards the indications, contraindications, and techniques of cervical cerclage. This article also focuses in detail on 4 areas of controversy, namely transabdominal cerclage, cervical cerclage for a short cervix, the management of cerclage after preterm premature rupture of the membranes, and the utility of a second (salvage) cerclage.

Abstract
OBJECTIVES To investigate the prevalence and timing of cervical cerclage placement in multiple gestations. METHODS Our perinatal database was queried for all multiple gestations delivered at Evanston Hospital from 12/95 through 12/00. This list was then cross-matched with billing and medical records for 'incompetent cervix' and 'cerclage.' The medical records of all deliveries </=26 weeks were reviewed in order to ascertain if cervical incompetence was responsible for the preterm delivery. RESULTS There were 802 deliveries of multiple gestations >/=14 weeks over a 5-year period. The number of patients that underwent cerclage placement was 29 or 3.6%. The mean gestational age at cerclage placement was 18.6+/-4.5 weeks (range 11-24.6). Twelve were elective or prophylactic while 17 were 'urgent' or 'emergent.' The mean gestational age for the 17 emergent cerclages was 21.4+/-2.2 weeks (range 16.6-24.6). When compared with those patients who did not undergo cerclage placement, there was no difference in maternal demographics including age, parity, or previous full-term delivery. There was a significant difference in the gestational age at delivery for the cerclage vs. no cerclage group; 29.3+/-5.6 vs. 34.4+/-4.6 weeks, respectively, and in the frequency of losses at </=26 weeks; 8/23 (38%) vs. 48/707 (6.8%), P<0.001. Ten of the losses in the no cerclage group appeared consistent with incompetent cervix for a total of 39/802 or 4.9% rate of cervical incompetence in our multiple gestation population. CONCLUSIONS The relatively low prevalence of cervical incompetence in our multiple gestations does not justify prophylactic cervical cerclage placement. Expectant management with serial cervical examinations starting at 16-18 weeks appears more prudent.

Abstract
OBJECTIVE To compare the perinatal outcome of triplet gestations with and without prophylactic cerclage. METHODS A retrospective chart review of all triplet gestations delivered between January 1988 and June 1997 was performed. Only women initiating prenatal care before 15 weeks gestation were included. The cerclage group was compared to the no-cerclage group for maternal and perinatal outcome variables. Student t-test, Chi-square, and Fisher's exact test were used for analysis. RESULTS Twenty of the 59 (33.8%) sets of triplet gestations had prophylactic cerclage. There were no differences between groups when compared for maternal age, parity, preterm labor rate, gestational diabetes, anemia, antenatal steroid use, histologic chorioamnionitis, and postoperative endometritis. In addition, there were no differences in mean birth weight, Apgar scores, respiratory distress syndrome (RDS), intraventricular hemorrhage/periventricular leucomalacia (IVH/PVL), and neonatal mortality. Although the mean gestational age at delivery for the cerclage group (32.8+/-2.4 weeks) was not different from the no-cerclage group (31.5+/-3.6 weeks), the proportion of pregnancies delivered at 31 weeks or more, and at 32 weeks or more, was significantly higher in the cerclage group (90 vs. 62%, P = .02; 80 vs. 54%, P = .05), respectively. In addition, the incidence of extremely low birth weight (LBW) was significantly decreased in the cerclage compared with the no-cerclage group (1.7 vs. 15.4%, P = .005). CONCLUSIONS Prophylactic cerclage decreased significantly the incidence of extremely LBW neonates in triplet pregnancies. The proportion of neonates delivered at 31 weeks or more, and at 32 weeks or more was higher in the cerclage group.

Abstract
Multiple gestations present a significant increase in fetal growth abnormalities in direct relationship to the number of fetuses present. Various definitions of birth weight discordancy exist (> or = 15%-40%). When first trimester discordancy in CRL or gestational sac diameter or early second trimester discordancies of BPD, HC, AC, or femur length are detected, genetic counseling and further work-up, including chromosomal analysis, should be considered. AC and SEFW are the best sonographic predictors of second and third trimester growth discordancy of twins. Discordant Doppler velocimetry of the umbilical arteries enhances ultrasonographic diagnosis of twin discordancy. Karyotyping also should be considered on second or third trimester diagnosis of growth discordancy. Twin-twin transfusion should be considered when growth discordancy is diagnosed in monochorionic gestations. Concordant twins with appropriate-for-gestational-age growth parameters should be followed with repeated sonographic assessment of fetal growth at approximately 4-week intervals. Discordant twins should be followed by repeat sonographic assessment of fetal growth at closer intervals, most probably every 2 weeks. Surviving singleton fetuses, after spontaneous fetal death of a twin at > 16 weeks of gestation, should be followed with antepartum surveillance similar to that of discordant twins. In rare cases of extremely premature twins with discordant growth and deteriorating fetal well-being of the growth-restricted twin, conservative management should be considered in favor of the normally grown fetus.
