Our study assessed the potential impact of the new criteria on the number of additional follow\u2010up sonograms these changes would engender.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective study of all first\u2010trimester sonograms in women with first trimester bleeding from 1999 to 2008 was conducted. Everyone included in the study had a visible gestational sac in the uterus. There were no pregnancies of unknown location or ectopic pregnancies included in this study cohort. Pregnancy of unknown location was used to describe cases in which there were no signs of pregnancy inside or outside the uterus on transvaginal sonography despite a positive pregnancy test result. A total of 1013 patients met the inclusion criteria.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Seven hundred fifty\u2010two patients (74%) had identifiable embryos, and 261 (26%) did not. Of those with an identifiable embryo, 286 (38%) had no detectable embryonic cardiac activity. The breakdown of crown\u2010rump lengths in this group was as follows: 100 measuring less than 5 mm, 36 measuring 5 to 7 mm, and 150 measuring 7 mm or greater. The breakdown of mean sac diameters in those without a visible embryo was as follows: 120 measuring less than 16 mm, 90 measuring 16 to 25 mm, and 51 measuring 25 mm or greater.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>When diagnosing a failed pregnancy, there can be no room for error. Only 126 of 1013 early pregnancies threatening to abort (12%) fell into the more conservative zones defined by the new compared to the former size criteria (crown\u2010rump length, 5\u20137 mm; mean sac diameter, 16\u201325 mm). Therefore, the potential impact of the new guidelines on follow\u2010up sonograms does not appear inordinate.<\/jats:p><\/jats:sec>","DOI":"10.7863\/ultra.33.9.1585","type":"journal-article","created":{"date-parts":[[2014,8,25]],"date-time":"2014-08-25T22:00:56Z","timestamp":1409004056000},"page":"1585-1588","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Impact of New Society of Radiologists in Ultrasound Early First\u2010Trimester Diagnostic Criteria for Nonviable Pregnancy"],"prefix":"10.1002","volume":"33","author":[{"given":"Maowen","family":"Hu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liina","family":"Poder","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roy A.","family":"Filly","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,9]]},"reference":[{"key":"e_1_2_5_2_1","first-page":"181","volume-title":"Ultrasonography in Obstetrics and Gynecology","author":"Laing FC","year":"2007"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.20563"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.2008.27.11.1559"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.176.1.2191372"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.1990.9.11.631"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.1991.10.2.63"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.10109"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.2010.29.5.685"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.10108"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.8884"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra1302417"}],"container-title":["Journal of Ultrasound in Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.7863%2Fultra.33.9.1585","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.7863%2Fultra.33.9.1585","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.7863\/ultra.33.9.1585","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,28]],"date-time":"2023-10-28T09:39:12Z","timestamp":1698485952000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.7863\/ultra.33.9.1585"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,9]]},"references-count":11,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2014,9]]}},"alternative-id":["10.7863\/ultra.33.9.1585"],"URL":"https:\/\/doi.org\/10.7863\/ultra.33.9.1585","archive":["Portico"],"relation":{},"ISSN":["0278-4297","1550-9613"],"issn-type":[{"value":"0278-4297","type":"print"},{"value":"1550-9613","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,9]]},"assertion":[{"value":"2013-11-28","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2013-12-28","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2014-09-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
