Objectives: After studying the article entitled “Comparison of Transabdominal and Transvaginal Sonograms in Evaluation of Cervical Length During Pregnancy,” you will be able to:
Describe the sonographic appearance of the cervical ≤2.5 cm measurement with transvaginal (TV) sonography and the potential for preterm birth (PTB)
Explain declining rates of preterm delivery when women are enrolled in screening programs using transvaginal cervical length (TV CL) measurements
Compare the accuracy and correlation of transabdominal cervical length (TA CL) of <2.9 cm and TV CL of ≤2.5 cm measurements and screening PTB from 18 to 24 weeks gestation
PTB worldwide has an annual incidence of 15 million and accounts for what percentage of pregnancies in the United States? 5% 20% 15% 10%
The TV sonogram in Figure 1 demonstrates? Normal cervix Mucus plug Y-shaped cervix Sludge
The published findings in Table 1 determined the most accurate time during pregnancy for TV sonographic detection range for short cervical length was. 18-20 weeks 16-22 weeks 20-26 weeks 18-24 weeks
According to Figure 5, the internal and external cervical os is? Well demonstrated on the TV image Not always visualized with the TA approach Well demonstrated with acoustic shadowing Visualized 95% of the time
A comparison of research discusses that TA CL as an initial screening between 18 and 22 weeks’ gestation is adequate for short cervix detection using what measurement? ≤2.5 cm ≤2.9 cm <2.9 cm <2.5 cm
