This may lead to the false diagnosis of placenta accreta spectrum resulting obstetric anxiety, overtreatment and potential iatrogenic morbidity. Despite potential similarities in the etiology, the manifestation and management of these two conditions is very different. The prenatal sonographic features of seven confirmed cases of simple uterine scar dehiscence with an underlying placenta previa were examined. The common sonographic features found for scar dehiscence was a thinned myometrium (&amp;lt;1\u2005mm) overlying a generally homogenous placenta and a placental bulge. There was absence of lacunae and features of hypervascularity including bridging vessels. Our findings suggest accurate discrimination between a simple scar dehiscence with the placenta underlying it and placenta accreta spectrum can be made on prenatal ultrasound if the placenta is carefully examined for the vascular features unique to PAS.<\/jats:p>","DOI":"10.3389\/frph.2023.1068377","type":"journal-article","created":{"date-parts":[[2023,10,20]],"date-time":"2023-10-20T07:10:58Z","timestamp":1697785858000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Absence of abnormal vascular changes on prenatal imaging aids in differentiating simple uterine scar dehiscence from placenta accreta spectrum: a case series"],"prefix":"10.3389","volume":"5","author":[{"given":"Theophilus K.","family":"Adu-Bredu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yaw Gyanteh","family":"Owusu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atta","family":"Owusu-Bempah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sally L.","family":"Collins","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,10,20]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e244286","DOI":"10.1136\/bcr-2021-244286","article-title":"Accurate prenatal discrimination of placenta accreta spectrum from uterine dehiscence is necessary to ensure optimal management","volume":"14","author":"Adu-Bredu","year":"2021","journal-title":"BMJ Case Rep"},{"key":"B2","doi-asserted-by":"publisher","first-page":"511","DOI":"10.1016\/j.ajog.2019.02.054","article-title":"Evidence-based guidelines for the management of abnormally invasive placenta: recommendations from the international society for abnormally invasive placenta","volume":"220","author":"Collins","year":"2019","journal-title":"Am J Obstet Gynecol"},{"key":"B3","doi-asserted-by":"publisher","first-page":"113","DOI":"10.23736\/S0026-4784.18.04333-2","article-title":"Updates on the management of placenta accreta spectrum","volume":"71","author":"Di Mascio","year":"2019","journal-title":"Minerva Ginecol"},{"key":"B4","doi-asserted-by":"publisher","first-page":"417","DOI":"10.1002\/uog.24890","article-title":"Debunking 20th century myths and legends about the diagnosis of placenta accreta spectrum","volume":"59","author":"Jauniaux","year":"2022","journal-title":"Ultrasound Obstet Gynecol"},{"key":"B5","doi-asserted-by":"publisher","first-page":"271","DOI":"10.1002\/uog.14952","article-title":"Proposal for standardized ultrasound descriptors of abnormally invasive placenta (AIP)","volume":"47","author":"Collins","year":"2016","journal-title":"Ultrasound Obstet Gynecol"},{"key":"B6","doi-asserted-by":"publisher","first-page":"745","DOI":"10.7863\/ultra.33.5.745","article-title":"Participants for the FIWI.
