Comparison of Transabdominal and Transvaginal Sonograms in Evaluation of Cervical Length During Pregnancy

| description | Objective:
A short cervix during pregnancy indicates a higher risk of preterm delivery. Transvaginal sonography is widely used for the detection of a short cervix. The literature indicates that 21–24 weeks is the most sensitive gestational age to assess transvaginal cervical length (TV CL) of ≤2.5 cm for potential preterm delivery. Pregnancies between 18 and 20 weeks’ gestation are generally performed transabdominally; thus, it could be beneficial to have a recognized correlation between the transabdominal cervical length (TA CL) measurement and the TV CL measurement at this earlier time period.
Materials and Methods:
An online database search produced 13 research articles to be reviewed. Inclusion criteria consisted of TA CL and TV CL assessment of singleton pregnancies with intact membranes.
Results:

A short cervix during pregnancy indicates a higher risk of preterm delivery. Transvaginal sonography is widely used for the detection of a short cervix. The literature indicates that 21–24 weeks is the most sensitive gestational age to assess transvaginal cervical length (TV CL) of ≤2.5 cm for potential preterm delivery.

Materials and Methods:
An online database search produced 13 research articles to be reviewed. Inclusion criteria consisted of TA CL and TV CL assessment of singleton pregnancies with intact membranes.
Results:
Findings indicate high diagnostic yield when a TA CL of <2.9 cm or TV CL of <2.5 cm is used for defining a shortened cervix when measured between 18 and 20 weeks’ gestation.
Conclusion:
This review of the literature indicates a correlation between average TA CL and average TV CL measurements, although the relationship widens as CLs become shorter.</description><identifier>ISSN: 8756-4793</identifier><identifier>EISSN: 1552-5430</identifier><identifier>DOI: 10.1177/87564793211012612</identifier><language>eng</language><publisher>Los Angeles, CA: SAGE Publications</publisher><ispartof>Journal of Diagnostic Medical Sonography, 2021-09, Vol.37 (5), p.466-471</ispartof><rights>The Author(s) 2021</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><cites>FETCH-LOGICAL-c279t-9f3acb08a7ee9a2ea2ee0da78268b04ac5fe165fbca873c34225814b83fe3cfd3</cites><orcidid>0000-0002-9031-9378</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://journals.sagepub.com/doi/pdf/10.1177/87564793211012612$$EPDF$$P50$$Gsage$$H</linktopdf><linktohtml>$$Uhttps://journals.sagepub.com/doi/10.1177/87564793211012612$$EHTML$$P50$$Gsage$$H</linktohtml><link.rule.ids>313,314,776,780,788,21798,27899,27901,27902,43597,43598</link.rule.ids></links><search><creatorcontrib>Fitzpatrick, Anna</creatorcontrib><creatorcontrib>DiGiacinto, Dora</creatorcontrib><title>Comparison of Transabdominal and Transvaginal Sonograms in Evaluation of Cervical Length During Pregnancy</title><title>Journal of Diagnostic Medical Sonography</title><description>Objective:
