Ultrasound of the cervix during pregnancy - time to notice the threat of miscarriage


Ultrasound of the cervix during pregnancy ultrasound of the cervix during pregnancy is included in the compulsory examination of pregnant women.During pregnancy, the cervix undergoes significant changes and gradually "matures" to leave.Violation of the physiological processes in the cervix - is, above all, the threat of miscarriage.

ultrasound of the uterus during pregnancy - planned research

ultrasound during pregnancy involves the study not only the condition of the fetus but also the mother.During routine ultrasound pay special attention to the condition of the walls of the uterus and cervix - it helps prevent miscarriage or other complications.

first ultrasound during pregnancy is carried to term of 11-13 weeks.In addition to the inspection of the fetus during ultrasound of the uterus during pregnancy is carried out research of the walls of the uterus (the presence miomatozyh, ie the tumor, nodes), cervical cancer, ovarian cancer.In the first trimester, there are two threats to the health and life of the pregnant woman's condition - a miscarriage and ectopic pregnancy Ectopic pregnancy - Fatal dangerous Ectopic pregnancy - Fatal dangerous .In many ways, the risk of complications depends on the condition of the cervix, so it is examined carefully.

In the second trimester an ultrasound of the uterus during pregnancy also carefully examine the uterine wall for the presence of fibroids, as well as check the status of the cervix.Complications of the second trimester of the mother - a miscarriage (late miscarriage) and bleeding.

Finally, the last ultrasound is not mandatory, it is prescribed in the period 32-34 weeks for the exclusion of certain fetal malformations, fetal clarify the situation, andAlso, if there is a threat of premature birth.Status of the cervix is ​​very important in this period.

ultrasound of the cervix during pregnancy

The cervix is ​​a muscular organ that is located at the bottom of the body of the uterus.Inside the cervix is ​​cervical or cervical canal that connects the uterus with the vagina.After the cervical canal of the uterus, and menstrual blood derived ottorgshayasya mucosa (endometrium) and into the uterus, and then into the fallopian tubes penetrating sperm to fertilize an egg.The main objectives of the cervix during pregnancy is to keep the fetus in the uterus and prevent it falling into the infection.

During pregnancy, the cervix undergoes significant changes, growing as they approach delivery.This process is called cervical ripening: it changes color and is solid at the beginning (keeping the fruit from the exit), and to leave softened.

ultrasound of the cervix during pregnancy is carried out to prevent miscarriage.

main criterion by which an ultrasound to determine the state of the cervix, is its length.That is the length of the cervix, which is measured during the ultrasound, we can assume the possible risk of miscarriage or premature birth.

The first ultrasound scheduled at 11-13 weeks of pregnancy cervical length should normally be between 35 and 45 millimeters.The consistency of her tight and inelastic.If the cervical length is 20 mm or less, there is a risk of miscarriage Miscarriage - why you lose the most precious thing? Miscarriage - why you lose the most precious thing? , as the weak cervix is ​​unable to hold the growing fetus.This condition is called cervical incompetence.

on ultrasound of the cervix during pregnancy and accounted for another criterion.The threat of miscarriage Miscarriage - whether it can be insured? Miscarriage - can you protect yourself from it? or premature birth may also say the presence of the V-shaped opening of the internal cervical os (out of the cervical canal Cervical canal - the path traversed by every person Cervical canal - the path traversed by every person , opening to the uterus).The more disclosure of the internal os, the greater the threat of miscarriage.

Approximately two weeks before the birth the cervix softens and shortened, which is a physiological process - the body prepares for childbirth.During labor, the cervix is ​​slowly shrinking, expanding its internal os and muscle ring stretch and open the birth canal.

possible pathology

main detectable pathology, which is primarily aimed at professionals holding ultrasound of the cervix during pregnancy is cervical incompetence (CIN) - a condition when the cervix begins to shorten the time before anddisclosed.The reason may be CIN: cervical injury during heavy previous births, abortions or surgical interventions, anomalies of the uterus, hormonal disorders, large fetus, multiple pregnancy, polyhydramnios.

With the threat of CIN in the cervix in the external os closed with stitches, mechanical tapering internal os.Sometimes, instead of sutures applied special obstetric ring made of plastic, which helps to withstand the load of the neck.
