• #1 Incompetent Cervix | American Pregnancy Association

  https://americanpregnancy.org/getting-pregnant/incompetent-cervix/

  During pregnancy, as the baby grows and gets heavier, it presses on the cervix. This pressure may cause the cervix to start to open before the baby is ready to be born. This condition is called incompetent cervix or weakened cervix, and it may lead to a miscarriage or premature delivery. However, an incompetent cervix happens in only about 1 out of 100 pregnancies. […] A weakened cervix can be caused by one or more of the following conditions: Previous surgery on the cervix, Damage during a difficult birth, Malformed cervix or uterus from a birth defect, Previous trauma to the cervix, such as a D&C (dilation and curettage) from termination or a miscarriage, DES (Diethylstilbestrol) exposure. […] An incompetent or weakened cervix happens in about 1-2% of pregnancies. Almost 25% of babies miscarried in the second trimester are due to incompetent cervix. […] The treatment for an incompetent or weakened cervix is a procedure that sews the cervix closed to reinforce the weak cervix. This procedure is called a cerclage and is usually performed between week 14-16 of pregnancy.

  American College of Obstetrics and Gynecologys (ACOG) defines an incompetent cervix as a painless dilation and delivery in the second trimester of pregnancy. […] The problem is weak cervical tissue causes or leads to premature birth or the loss of a pregnancy. […] Cervical incompetence occurs in about 1 out of 100 pregnancies. About 25% of miscarriages in the second trimester are due to incompetent cervix. […] The exact reason why cervical incompetency occurs in certain pregnancies is not known. However, there are a number of specific risk factors for incompetent cervical including: Cervical trauma some surgical procedures that are used to treat cervical abnormalities related to abnormal PAP smear can cause cervical insufficiency. Other procedures such as dilation and curettage (DC) procedures could be associated with cervical insufficiency.

  https://emedicine.medscape.com/article/1979914-overview

  Cervical insufficiency is thought to be related to a structural defect in tensile strength at the cervicoisthmic junction, but other disorders (eg, decidual inflammation, intrauterine infection, hemorrhage, uterine overdistension) may result in premature cervical shortening, ultimately leading to preterm delivery. […] Cervical insufficiency may occur as a result of a functional defect in the cervix, which can be due to an anatomic abnormality (congenital Mllerian anomalies), in utero exposure to diethylstilbestrol (DES), or collagen disorders (Ehlers-Danlos syndrome). […] Acquired causes of cervical insufficiency include obstetric trauma (eg, cervical laceration during labor and delivery), mechanical dilation of the cervix during gynecologic procedures, and cervical conization, which may be performed via cold knife, laser, or loop electrosurgical excision procedure (LEEP).

  Those who have alterations in the process, due heritable defects in collagen and elastin synthesis or assembly, have an increased risk of cervical insufficiency. […] As early as 1962 Danforth and Buckingham suggested that cervical insufficiency was not an all or none phenomenon. […] Based on analyses of cervical tissue for collagen/muscle ratios and recognizing the contribution of past traumatic disruption of cervical continuity, these investigators proposed a classification scheme to explain the clinical syndrome of cervical insufficiency. […] Cervical insufficiency was generally viewed as dichotomous (possibly because available treatment strategies were similarly devised). […] The cellular and biochemical changes suggested that cervical dilation in pregnancy is a dynamic process, and this might explain why a woman could have a pregnancy outcome consistent with cervical insufficiency in one pregnancy, but then without treatment, have a subsequent term birth.

  Cervical insufficiency is thought to be due to congenital or acquired defects in the structure or function of the cervix. […] Any disruption in these processes or to the structural integrity of the cervix itself could result in early cervical ripening, cervical insufficiency, and preterm birth or miscarriage. […] These cervical defects, which may be congenital or acquired, cause cervical insufficiency by disrupting normal cervical remodeling during pregnancy, leading to early cervical ripening, preterm birth, or miscarriage. […] The most common acquired cause of cervical insufficiency is cervical trauma, which may result from cervical lacerations during childbirth, especially if the birth was precipitous or following a prolonged second stage of labor, cervical conization, loop electrosurgical excision procedures (LEEP), or any other surgical procedure requiring mechanical cervical dilation, including dilation and curettage or hysteroscopy.

  An incompetent cervix happens when weak cervical tissue causes or plays a part in a premature birth or the loss of a healthy pregnancy. […] An incompetent cervix can be a hard problem to diagnose and treat. If your cervix begins to open early, or if you’ve had cervical insufficiency in the past, you might benefit from treatment. This might include having a procedure done to close the cervix with strong sutures, called a cervical cerclage. […] Risk factors for an incompetent cervix include: Cervical trauma. A previous procedure or surgery on the cervix could lead to an incompetent cervix. […] Certain uterine conditions might cause an incompetent cervix. Genetic problems affecting a type of protein that makes up your body’s connective tissues, called collagen, might cause an incompetent cervix. […] An incompetent cervix may be risky for your pregnancy. Possible complications include: Premature birth. Pregnancy loss. […] If you’ve had an incompetent cervix during one pregnancy, you’re at risk of premature birth or pregnancy loss in later pregnancies.

  https://www.clinicaladvisor.com/features/cervical-insufficiency-trauma-insights-diagnosis-management/

  Cervical insufficiency (CI), also known as incompetent cervix, is an obstetric complication in which the cervix is unable to support a full-term pregnancy. This condition is characterized by a history of recurrent pregnancy losses in the second or early-third trimester with no other cause. […] The pathophysiology of CI is not well-understood, although all causes are related to compromise in the structure or function of the cervix. […] Acquired causes of CI include trauma from procedures such as conization or cone biopsy. […] Mean cervical length is shorter in pregnant persons with a history of prior LEEP or cone biopsy. […] These individuals are also at increased risk for CI, PTB, perinatal mortality, and other negative birth outcomes. […] Understanding the risks for CI and PTB following a traumatic cervical procedure is important information for persons considering future pregnancies.

  The cervix is labelled Incompetent when it is unable to retain an intrauterine gestation until term because of deficiency in structure or function. […] The mechanism involves a complex physiological process of uterine muscle rearrangement as well as biochemical changes in the cervix. […] The function of the cervix during pregnancy depends on the regulations of connective tissue metabolism. […] The biochemical events implicated in the cervical ripening are: decrease in total collagen content, increase in collagen solubility, increase in collagenolytic activity. […] The modern understanding of cervical incompetence is as follows: The cervical competence is an active, not passive, phenomenon. It is a specific entity involving not just an abnormality or defect of cervical collagen, but is also due to either absence of the usual cervical musculature in cases of congenital cervical incompetence or injury or damage to the cervical musculature caused by previous trauma.

  Cervical insufficiency refers to painless cervical dilation that leads to second-trimester fetal expulsion (miscarriage or preterm birth). […] Structural cervical weakness is the likely cause of cervical insufficiency. The weakness may be secondary to (see 'Risk factors’ below): […] Decidual inflammation/infection, bleeding at the interface of the decidua and placenta, or uterine overdistension, which initiates biochemical changes that lead to premature cervical shortening. This pathway likely results in a single rather than recurrent second-trimester miscarriage or preterm birth.

  In case of cervical insufficiency 2. During pregnancy in the trimester, there is recurrent painless dilation of the cervix (cervix uteri) without contractions. There is a simultaneous dilation and softening of the cervix and a shortening of the cervix to less than 2.5 cm. If it goes unnoticed, cervical insufficiency can lead to pregnancy loss. […] A multifactorial genesis is suspected, involving infections as well as immunologic and mechanical causes. Increased infections with beta-hemolytic streptococci, chlamydia, ureaplasma, gardnerella or other microbes play an important role here. They are important because of the release of inflammatory mediators (e.g. prostaglandins) associated with infection. […] The exact causes of cervical insufficiency are unknown. It is now assumed that hormonal changes play an important role in an average of one third of pregnancy (2nd trimester). Apparently, hormonal changes cause premature softening of the tight connective tissue of the cervix and cervical canal.

  Cervical insufficiency has been traditionally defined as painless cervical dilation that leads to mid-trimester pregnancy loss in the absence of other causes (e.g., labor, trauma, major fetal anomaly, stillbirth). […] In recent years, the definition of cervical insufficiency has expanded to include women with a prior spontaneous preterm birth and evidence of cervical shortening (25 mm) on transvaginal ultrasound. […] The cervix plays an essential role in maintenance of a normal pregnancy; disruption of the normal anatomic structure or biologic function of the cervix may foretell preterm delivery. […] Early in pregnancy the cervix begins to undergo structural changes with increased vascularity, stromal hypertrophy, glandular hypertrophy and hyperplasia, and structural changes of the extracellular matrix.

  It is triggered by increased intrauterine pressure (IUD) encountering a structurally weakened cervix. There is early disintegration of the cervical collagen structure. As a result, the cervix can no longer cope with the increased pressure and dilates. […] There is an increased risk after previous surgical interventions such as conization and after mechanical cervical dilatation in the context of gynecological interventions. Injury to the cervix uteri in previous pregnancies and congenital uterine anomalies can also cause cervical insufficiency. […] Diagnosis of cervical insufficiency is based on a typical obstetric history in combination with transvaginal ultrasound measurement of cervical length.

  Incompetent cervix is characterized by the structural weakness of the cervix, particularly the cervical tissue and its supporting structures. […] Changes in the connective tissue of the cervix, often related to a combination of genetic and environmental factors, contribute to its inability to withstand the pressure of a growing fetus. […] The cervix may start to dilate prematurely, usually during the second trimester, without the presence of contractions or labor. This early dilation can lead to pregnancy loss or preterm birth. […] Incompetent cervix often progresses without noticeable symptoms, making early detection challenging. As a result, it may only be identified after the occurrence of pregnancy loss or preterm birth.

  Cervical insufficiency has been traditionally defined as painless cervical dilation that leads to mid-trimester pregnancy loss in the absence of other causes (e.g., labor, trauma, major fetal anomaly, stillbirth). […] In recent years, the definition of cervical insufficiency has expanded to include women with a prior spontaneous preterm birth and evidence of cervical shortening (25 mm) on transvaginal ultrasound. […] The cervix plays an essential role in maintenance of a normal pregnancy; disruption of the normal anatomic structure or biologic function of the cervix may foretell preterm delivery. […] Early in pregnancy the cervix begins to undergo structural changes with increased vascularity, stromal hypertrophy, glandular hypertrophy and hyperplasia, and structural changes of the extracellular matrix.

  The cervix is labelled Incompetent when it is unable to retain an intrauterine gestation until term because of deficiency in structure or function. […] The mechanism involves a complex physiological process of uterine muscle rearrangement as well as biochemical changes in the cervix. […] The function of the cervix during pregnancy depends on the regulations of connective tissue metabolism. […] The biochemical events implicated in the cervical ripening are: decrease in total collagen content, increase in collagen solubility, increase in collagenolytic activity. […] The modern understanding of cervical incompetence is as follows: The cervical competence is an active, not passive, phenomenon. It is a specific entity involving not just an abnormality or defect of cervical collagen, but is also due to either absence of the usual cervical musculature in cases of congenital cervical incompetence or injury or damage to the cervical musculature caused by previous trauma.

  It is triggered by increased intrauterine pressure (IUD) encountering a structurally weakened cervix. There is early disintegration of the cervical collagen structure. As a result, the cervix can no longer cope with the increased pressure and dilates. […] There is an increased risk after previous surgical interventions such as conization and after mechanical cervical dilatation in the context of gynecological interventions. Injury to the cervix uteri in previous pregnancies and congenital uterine anomalies can also cause cervical insufficiency. […] Diagnosis of cervical insufficiency is based on a typical obstetric history in combination with transvaginal ultrasound measurement of cervical length. A sonographic cervical length 25 mm before 34+0 weeks of gestation is considered shortened. In patients with advanced cervical dilatation, physical examination, inspection and palpation alone are sufficient to diagnose cervical insufficiency.

  https://americanpregnancy.org/getting-pregnant/incompetent-cervix/

  During pregnancy, as the baby grows and gets heavier, it presses on the cervix. This pressure may cause the cervix to start to open before the baby is ready to be born. This condition is called incompetent cervix or weakened cervix, and it may lead to a miscarriage or premature delivery. However, an incompetent cervix happens in only about 1 out of 100 pregnancies. […] A weakened cervix can be caused by one or more of the following conditions: Previous surgery on the cervix, Damage during a difficult birth, Malformed cervix or uterus from a birth defect, Previous trauma to the cervix, such as a D&C (dilation and curettage) from termination or a miscarriage, DES (Diethylstilbestrol) exposure. […] An incompetent or weakened cervix happens in about 1-2% of pregnancies. Almost 25% of babies miscarried in the second trimester are due to incompetent cervix. […] The treatment for an incompetent or weakened cervix is a procedure that sews the cervix closed to reinforce the weak cervix. This procedure is called a cerclage and is usually performed between week 14-16 of pregnancy.

  https://my.clevelandclinic.org/health/diseases/17912-incompetent-cervix

  Incompetent cervix occurs when your cervix opens, weakens or shortens too early in pregnancy. Its also known as cervical insufficiency. It can cause problems including miscarriage (loss of the pregnancy) and premature birth (being born before 37 weeks of pregnancy). […] With cervical insufficiency, your cervix may soften, open or shorten before the fetus is old enough to be born. This puts the fetus at risk for being born too soon before their organs are fully developed. […] Healthcare experts havent identified an exact cause for incompetent cervix. However, they know certain factors can put you at risk. These risk factors include damage to your cervix, prior surgeries to your cervix or being born with an irregularly-shaped cervix or uterus. […] A miscarriage is the loss of pregnancy before 20 weeks. Think of your cervix as a door between your uterus (where the fetus grows) and your vagina. This door should remain closed ideally until your due date. If this door opens too soon, the fetus may be born before their organs, bones and other structures are fully grown. Almost 25% of second trimester miscarriages are due to an incompetent cervix. Cervical insufficiency can also cause pregnancy loss after 20 weeks (stillbirth).
