Pessary preterm birth

Begoña Martinez de Tejada
BACKGROUND: Preterm delivery is a major health problem and contributes to more than 50% of all neonatal and infant deaths. Recently, there has been a renewed interest in the use of cervical pessaries as a safe and effective intervention with few maternal side-effects for the prevention of preterm birth in both single and twin pregnancies. CASE PRESENTATION: A 43-year-old gravida 5, para 1 (previous preterm birth at 24 weeks) patient with an in vitro fertilization twin pregnancy had an Arabin cervical pessary placed at 19 weeks of pregnancy due to the presence of cervical funneling identified by ultrasound screening...

In France, 60,000 neonates are born preterm every year (7.4%), half of them after the spontaneous onset of labor. Among preventable risk factors of spontaneous prematurity, only cessation of smoking is associated with decreased prematurity (level of evidence [LE]1). It is therefore recommended (Grade A). Routine screening and treatment of vaginal bacteriosis is not recommended in the general population (Grade A). The only population for which vaginal progesterone is recommended is that comprising asymptomatic women with singleton pregnancies, no history of preterm delivery, and a short cervix at 16-24 weeks of gestation (Grade B)...

BACKGROUND: Clinically, once a woman has been identified as being at risk of spontaneous preterm birth (sPTB) due to a short cervical length, a decision regarding prophylactic treatment must be made. Three interventions have the potential to improve outcomes: cervical cerclage (stitch), vaginal progesterone and cervical pessary. Each has been shown to have similar benefit in reduction of sPTB, but there have been no randomised control trials (RCTs) to compare them. METHODS: This open label multi-centre UK RCT trial, will evaluate whether the three interventions are equally efficacious to prevent premature birth in women who develop a short cervix (<25 mm on transvaginal ultrasound)...

Preterm birth (PTB), defined as delivery at <37 weeks of gestation, is the most important cause of neonatal morbidity and mortality. Therefore, preventing PTB is one of the main goals in obstetric care. In this review, we provide an overview of the current available literature on screening for risk factors for PTB and a summary of preventive strategies in both low-risk and high-risk women with singleton or multiple gestations. Furthermore, current challenges and future prospects on PTB are discussed. For an optimal prevention of PTB, risk stratification should be based on a combination of (maternal) risk factors, obstetric history, and screening tools...

We present a rare case of a complication after pessary insertion during pregnancy due to short cervix. A woman in the 35th week of gestation was admitted to the Department of Perinatology due to preterm labor. The patient's history revealed cervical pessary insertion during the 29th week of pregnancy due to a cervix of 18 mm in length. Because of threatened preterm labor, the pessary was removed. After pessary removal, a rupture of the cervix was diagnosed. Because of active labor and cervical rupture, a cesarean section was performed and a healthy newborn was delivered...

AIM: We compared the effectiveness of a combined treatment involving cervical pessary plus vaginal progesterone to vaginal progesterone alone in decreasing the rate of preterm birth in women with short cervix in the second gestational trimester. METHODS: This prospective, open-label, randomized clinical trial was conducted on 144 pregnant women with singleton pregnancy who had a cervical length ≤ 25 mm, at 18-22 gestational weeks (GW). Seventy-three patients were assigned to receive 400 mg of daily vaginal progesterone (group A), and 73 to receive cervical pessary plus 400 mg of daily vaginal progesterone (group B), until the 37th GW...

BACKGROUND: Preterm birth is a major cause of neonatal mortality and morbidity. As preventive strategies are largely ineffective, threatened preterm labor is a frequent problem that affects approximately 10 % of pregnancies. In recent years, risk assessment in these women has incorporated cervical length measurement and fetal fibronectin testing, and this has improved the capacity to identify women at increased risk for delivery within 14 days. Despite these improvements, risk for preterm birth continues to be increased in women who did not deliver after an episode of threatened preterm labor, as indicated by a preterm birth rate between 30 to 60 % in this group of women...

BACKGROUND: The Pessary for the Prevention of Preterm Birth Study (PS3) is an international, multicenter, randomized clinical trial designed to examine the effectiveness of the Arabin pessary in preventing preterm birth in pregnant women with a short cervix. During the design of the study two methodological issues regarding power and sample size were raised. Since treatment in the Standard Arm will vary between centers, it is anticipated that so too will the probability of preterm birth in that arm...

Preterm birth (PTB) represents a heavy burden in modern obstetrics as it is a major cause of perinatal morbidity and mortality. After the introduction of transvaginal sonography (TVS) screening, secondary prevention of PTB has been re-evaluated on the basis of pre-existing cervical length (CL) and meanwhile the cervical pessary has become an object of increasing interest. This device consists of a silicone cone acting mechanically, that can be easily placed or removed, but whose efficacy is still controversial...

A retrospective study was conducted to evaluate the effect of Arabin cervical pessary in twin pregnancies with cervical length (CL)  <25 mm between 21 and 31 weeks. Forty patients receiving pessary were matched with 40 controls without pessary. They were matched for gestational age (GA) at admission and CL. GA at delivery, delivery before 36, 34 and 32 weeks, latency between detection of short cervix and delivery, and duration of hospital admission were compared between groups. Women with the pessary delivered at higher GA compared to controls (35 vs...

Prevention of spontaneous preterm birth is an important public health priority. Pessary may be a potential therapy in cases of cervical insufficiency, in singleton and multiple gestations. Availability of transvaginal sonography for accurate assessment of cervical length is allowing for the tailoring of therapy to a more specific subset of patients who may benefit from this treatment. Pessary therapy is attractive given the favorable side effect profile, low cost, and ease of placement and removal. Large randomized trials are ongoing to validate initial favorable findings...

BACKGROUND: Preterm birth is the leading cause of neonatal and infant death and of disability among survivors. It is unclear whether a pessary inserted around the cervix reduces the risk of preterm singleton birth. METHODS: We conducted a multicenter, randomized, controlled trial comparing pessary placement with expectant management (control) in girls and women who were pregnant with singletons (singleton pregnancies) and who had a cervical length of 25 mm or less at 20 weeks 0 days to 24 weeks 6 days of gestation...

OBJECTIVE: To evaluate cervical pessary as an intervention to prevent preterm birth in twin pregnancies with a short cervix. METHODS: This was a retrospective cohort study of twin pregnancies managed by a single maternal-fetal medicine practice from 2005 to 2015. We included patients at 28 weeks of gestation or less who were diagnosed with a cervical length less than 20 mm. At the time of diagnosis, all patients were prescribed vaginal progesterone. Starting in 2013, they were also offered pessary placement in addition to vaginal progesterone...

Preterm birth is a major concern in modern obstetrics, and an important source of morbidity and mortality in newborns. Among twin pregnancies, especially, preterm birth is highly prevalent, and it accounts for almost 50% of the complications observed in this obstetrical population. In this article, we review the existing literature regarding the prediction and prevention of preterm birth in both symptomatic and asymptomatic twin pregnancies. In asymptomatic twin pregnancies, the best two predictive tests were cervical length (CL) measurement and cervicovaginal fetal fibronectin (fFN) testing...

Sonographic evaluation of the uterine cervix has evolved as one of the best clinical tools available for the prediction of subsequent spontaneous preterm birth (PTB), particularly when combined with prior poor obstetric history. There is a growing body of evidence describing interventions for short cervix that reduce the risk of preterm delivery and improve neonatal outcomes. Yet, given the significant heterogeneity in the pathways that lead to PTB, understanding the specific clinical characteristics of women who may benefit from a given intervention is critical to appropriate implementation...
