The first segment of the ACA (ACA-S1) was recorded just after its origin from the internal carotid artery in the same plane as the middle cerebral artery (MCA). The second segment (ACA-S2) was recorded distal to the outlet of the anterior communicating artery. <i>Results:<\/i> The ACA pulsatility index (PI) behaved similarly in both segments, with a constant increase until 28 weeks followed by a decrease until the end of pregnancy [ACA-S1 PI = 3.49 \u2013 0.37 \u00d7 gestational age (GA) \u2013 (0.0063 \u00d7 GA<sup>2<\/sup>), SD = 0.6 \u2013 0.061 \u00d7 GA \u2013 (0.001 \u00d7 GA<sup>2<\/sup>); ACA-S2 PI = 1.54 \u2013 0.22 \u00d7 GA \u2013 (0.0037 \u00d7 GA<sup>2<\/sup>), SD = 0.206 + (0.0037 \u00d7 GA)]. Peak systolic velocities in both segments showed a constant increase from 20 to 40 weeks of gestation. No significant differences were found between the 2 segments with regard to any Doppler parameter. However, the angle of insonation and the time spent on examination were significantly lower and reproducibility was better for ACA-S1. <i>Conclusion:<\/i> Despite showing similar Doppler values, ACA-S1 has a higher reliability than ACA-S2 and can be recorded in the same anatomical projection as the MCA.<\/jats:p>","DOI":"10.1159\/000253847","type":"journal-article","created":{"date-parts":[[2009,11,2]],"date-time":"2009-11-02T15:58:45Z","timestamp":1257177525000},"page":"33-39","source":"Crossref","is-referenced-by-count":25,"title":["Reference Values for Doppler Parameters of the Fetal Anterior Cerebral Artery throughout Gestation"],"prefix":"10.1159","volume":"69","author":[{"given":"J.A.","family":"Benavides-Serralde","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Hern\u00e1ndez-Andrade","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Figueroa-Diesel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Oros","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.A.","family":"Feria","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Scheier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Figueras","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Gratac\u00f3s","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2009,11,1]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002%2Fuog.4084"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1469-0705.2002.00758.x"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1080%2F08035250510031151"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.0960-7692.2001.00591.x"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016%2FS0306-5456%2801%2900222-4"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016%2F0020-7292%2891%2990817-O"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ejogrb.2006.12.015"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1469-0705.1998.11010030.x"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1002%2Fuog.122"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1159%2F000099160"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1017%2FS0021878298003409"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1002%2Fuog.2816"}],"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/253847","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/253847","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T21:11:42Z","timestamp":1745442702000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000253847"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,11,1]]},"references-count":12,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2010,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000253847","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,11,1]]}}}
