The Difference Between Elasticity of the Uterine Cervix in Singleton and Twin Pregnancies

2014-11-18 05:23:21 | BioPortfolio

Summary

The investigators aim to compare elasticity of the uterine cervix in singleton and twin pregnancies of similar gestational age.

Description

Softening of the uterine cervix occurs during pregnancy.There is a possibility that this process occurs earlier in twin versus singleton pregnancies.The softening of the cervix is reflected by the level of its elasticity which can be measured sonoelastographically. A two dimension image of the cervix is obtained in the midsagittal section and the length is noted. A 2nd sonoelastography image is obtained before pressure is applied with the transducer in the area of the internal os and a third sonoelastography image is obtained until no more shortening of the anterior-posterior diameter is observed.Elastography measurements of the internal os are performed using a color map: red (soft), yellow (medium soft), blue (medium hard) and purple (hard) before and after the application of strain.The change between the color maps before and after strain application in singleton pregnancies will be compared to the change in twin pregnancies of similar gestational age.

Medical and Biotech [MESH] Definitions

Proteins produced by organs of the mother or the PLACENTA during PREGNANCY. These proteins may be pregnancy-specific (present only during pregnancy) or pregnancy-associated (present during pregnancy or under other conditions such as hormone therapy or certain malignancies.)

The state of PREGNANCY in women with DIABETES MELLITUS. This does not include either symptomatic diabetes or GLUCOSE INTOLERANCE induced by pregnancy (DIABETES, GESTATIONAL) which resolves at the end of pregnancy.

Unintended accidental pregnancy, including pregnancy resulting from failed contraceptive measures.

Pregnancy in which the mother and/or FETUS are at greater than normal risk of MORBIDITY or MORTALITY. Causes include inadequate PRENATAL CARE, previous obstetrical history (ABORTION, SPONTANEOUS), pre-existing maternal disease, pregnancy-induced disease (GESTATIONAL HYPERTENSION), and MULTIPLE PREGNANCY, as well as advanced maternal age above 35.

MULTIPLE PREGNANCY with EMBRYO IMPLANTATION occuring at different locations, involving both an intrauterine site and an extrauterine (ECTOPIC PREGNANCY) site.
