Case of lower segment uterine contraction, follow up ultrasound

The patient has a history of preterm deliveries, which puts her at an increased risk for preterm labor in this pregnancy. The ultrasound findings of lower segment uterine contraction is concerning for preterm labor. Vaginal progesterone tablets are being used to try to prevent preterm labor.

The follow-up ultrasound scan showed that the cervix is still 3.8 cm long, but there is no funneling present. This is a good sign, as funneling is a sign that the cervix is starting to dilate. However, the lower segment of the uterus still appears contracted. This could be a sign that the patient is still at risk for preterm labor.

The patient's healthcare provider will need to continue to monitor her closely for signs of preterm labor. If the patient starts to have contractions, or if the cervix starts to dilate or efface, she will need to be treated for preterm labor.

Here are some things the patient can do to help reduce her risk of preterm labor:

• Get regular prenatal care.
• Take her prenatal vitamins.
• Eat a healthy diet.
• Get enough sleep.
• Avoid smoking and drinking alcohol.
• Manage her stress levels.

If the patient has any concerns about her pregnancy, she should talk to her healthcare provider.

Persistent lower segment uterine contractions (LUS contractions) in the second trimester of pregnancy: can have a significant impact on cervical length and uterocervical angle. These contractions can lead to an increase in cervical length, which can make it more difficult to determine if a woman is at risk for preterm labor. Additionally, LUS contractions can cause the uterocervical angle to decrease, which can also increase the risk of preterm labor.

The exact reason why LUS contractions occur in the second trimester is not fully understood. However, it is thought that they may be due to hormonal changes or to the stretching of the uterus as the fetus grows.

Significance:

In most cases, LUS contractions are not a cause for concern. However, if they are persistent or if they are accompanied by other symptoms such as vaginal bleeding or cramping, it is important to see a doctor.

Here are some of the potential implications of persistent LUS contractions in the second trimester:

• Increased risk of preterm labor
• Difficulty determining if a woman is at risk for preterm labor
• Decreased uterocervical angle
• Increased risk of preterm birth

Here are some of the things that your doctor may do to assess your risk for preterm labor:

• Ask you about your medical history and your pregnancy history
• Perform a physical examination
• Order ultrasound tests to measure your cervical length and uterocervical angle
• Order blood tests to check your hormone levels

If your doctor determines that you are at risk for preterm labor, they may recommend that you:

• Take bed rest
• Avoid certain activities
• Take medication to prevent preterm labor

With proper care, most women who experience persistent LUS contractions in the second trimester are able to carry their babies to term.
