Preterm cervical ripening may lead to cervical insufficiency or preterm delivery. Moreover, delayed cervical ripening has been implicated in a prolonged latent phase of labor at term. This chapter will review the anatomy and physiology of the uterine cervix during pregnancy and focus on the diagnostic and therapeutic challenges of cervical insufficiency and the role of cerclage in obstetrics. Anatomy The uterus is composed of three parts: corpus, isthmus and cervix. The corpus is the upper segment of the organ and predominantly contains smooth muscle (myometrium). The isthmus lies between the anatomical internal os of the cervix and the histological internal os, and during labor, gives rise to the lower uterine segment. The anatomical internal os refers to the junction between the uterine cavity and the cervical canal, while the histologic internal os is the region where the epithelium changes from endometrial to endocervical.1 The term “fibromuscular junction” was introduced by Danforth, who identified the boundary between the connective tissue of the cervix and the myometrium.

  • Alternative Treatment for a Short Cervix: the Cervical Pessary Vanita B
    Alternative Treatment for a Short Cervix: The Cervical Pessary Vanita B. Dharan, MD,* and Jack Ludmir, MD† Preterm birth is the leading cause of perinatal morbidity and mortality in the United States. The risk of preterm birth is inversely proportional to the length of the cervix on transvaginal sonography. The traditional treatment for a short cervix has been cerclage and recently there are newer trials using progesterone for this same indication. This manuscript reviews the published data regarding the use of an old method for the treatment of cervical insufficiency, “The Cervical Pessary.” A MEDLINE search was performed and articles published since 1959 regarding the use of pessary for cervical insufficiency were identified and reviewed. The pessary may represent an easy and safe intervention in the treatment of a short cervix diagnosed in the midtrimester. Further research is merited to evaluate the role of the cervical pessary as an alternative treatment for a short cervix or for women at high risk for preterm birth.

Rationale 2.1. Justification of the relevance of the trial. Preterm birth complicates 13% of all pregnancies worldwide and is the most important cause of neonatal morbidity and mortality.1 Although disability-free survival rates have increased over the years as a result of improved facilities and treatments, preterm birth is still accountable for 75% of all perinatal deaths and >50% of morbidities. 2,3 Women with a history of a preterm delivery have a distinctly increased risk to deliver preterm in a subsequent pregnancy. This risk ranges from 11,1% with one previous preterm delivery up to 28% for two previous preterm deliveries.4 This also applies to women with a history of a second trimester fetal-loss after 20 weeks of gestation who show an increased risk of 12% for preterm birth in a subsequent pregnancy.5 Yet another independent risk factor for PTB is a previous cervical surgery; after a single surgical conisation the risk of PTB increases almost 5 fold and after two even10-fold.6 One treatment option for prevention of preterm birth is a cervical pessary.

  • Maternal Sepsis Complicating Arabin Cervical Pessary Placement for the Prevention of Preterm Birth: a Case Report Begoña Martinez De Tejada

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. She developed chorioamnionitis and sepsis and delivered at 21 3/7 weeks after extraction of the pessary. Conclusion: Severe maternal infection may complicate pessary treatment for the prevention of preterm birth. Careful follow-up is necessary in women with a cervical pessary during pregnancy, particularly when important funneling is present. Keywords: Maternal sepsis, Cervical pessary, Medical complications, Prevention, Preterm birth Background cervix treated with cervical pessary compared to the Preterm birth (PTB) is defined as delivery before 37 non-treated group [3].

  • Cervical Pessary in Prevention of Preterm Birth: a Case Series*
    Cervical pessary in prevention of preterm birth: A case series* By Erika Gail G. Hernandez, MD and Mary Anne Tabaquero, MD, FPOGS Department of Obstetrics and Gynecology, St. Luke’s Medical Center, Quezon City ABSTRACT Preterm birth defined as birth between 20-37 weeks age of gestation, poses major concerns as it causes serious health problems. Across 184 countries, the rate of preterm birth ranges from 5% to 18% of babies born and the Philippines ranks 8th out of 184 countries for the number of babies born prematurely, and ranks 17th for the total number of deaths due to complications from preterm birth. Management of incompetent cervix as one of the causes of preterm birth is cerclage. However, pessary insertion is an alternative especially in cases where cerclage may not be employed. To date, there have been no local published reports on effectiveness of pessary in prevention of preterm birth. Hence this study aims to report on cases supporting the use of pessary in preterm birth. This is a case series of three patients with short functional cervical lengths (<2.5 cm) seen in ultrasound, managed with pessary insertion showing its effectiveness in prolonging pregnancy. In conclusion, pessary is an affordable and safe alternative management of preterm birth which may be employed in our setting. Future clinical trials may be helpful in strengthening this evidence. Keywords: Pessary, preterm birth, cervical incompetence INTRODUCTION this persists as long as the pessary remained in situ.4 This case series aims to report on three cases in essary is a device fitted into the vagina to provide our institution supporting the effectiveness of pessary in structural support to pelvic organs.
