UA hPSV-DT was measured with Doppler ultrasound in the same wave used to measure the pulsatility index. UA hPSV-DT values were correlated with perinatal outcome. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; UA hPSV-DT &lt;5th percentile was found in 87 and 98% of fetuses with moderate and severe FGR, respectively. 94% of fetuses with a UA hPSV-DT &lt;90 ms had poor perinatal outcome including perinatal death or prolonged admission to the neonatal intensive care unit. None of the fetuses had a UA hPSV-DT &lt;70 ms. Perinatal death occurred in 39 fetuses; UA hPSV-DT was abnormal in all of them, with 95% of these fetuses having values of \u2264120 ms. In the group of fetuses with absent\/reverse end-diastolic velocity in the UA, the perinatal mortality rate was 51% for those with a UA hPSV-DT \u226490 ms and only 23% for those having a UA hPSV-DT &gt;90 ms (p &lt; 0.01). &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; UA hPSV-DT seems to be a useful technique in the evaluation of pregnancies at risk for FGR and perinatal death. Additionally, hPSV-DT was shown to be a good predictor of perinatal death, with values of &lt;90 ms corresponding to imminent risk of intrauterine demise and values of &lt;70 ms being likely to be incompatible with intrauterine life.<\/jats:p>","DOI":"10.1159\/000442049","type":"journal-article","created":{"date-parts":[[2015,12,22]],"date-time":"2015-12-22T22:03:44Z","timestamp":1450821824000},"page":"128-134","source":"Crossref","is-referenced-by-count":6,"title":["Umbilical Artery Half-Peak Systolic Velocity Deceleration Time in Fetal Growth Restriction"],"prefix":"10.1159","volume":"40","author":[{"given":"Juan Carlos","family":"Bustos","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vivian","family":"Gonzalez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Waldo","family":"Sepulveda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2015,12,23]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2013.08.021"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000429658.85846.f9"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2393-14-63"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.2008.055251"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1055\/s-0029-1223284"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2012.06.039"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1002\/uog.989"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1002\/uog.13190"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2010.08.055"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1097\/OGX.0b013e31826a5c6f"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2012.01.022"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.earlhumdev.2005.09.008"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1046\/j.0960-7692.2001.00591.x"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2013.08.039"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1002\/uog.5185"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.64.2.133"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1159\/000431321"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(85)90298-4"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.4067\/S0034-98872004001000001"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1515\/jpme.1990.18.3.165"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1007\/s00404-010-1597-8"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2005.07.032"}],"container-title":["Fetal Diagnosis and Therapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/442049","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/442049","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/442049","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:05:53Z","timestamp":1745431553000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000442049"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,12,23]]},"references-count":22,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2016,8,30]]},"published-print":{"date-parts":[[2016,9,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000442049","archive":["Portico"],"relation":{},"ISSN":["1015-3837","1421-9964"],"issn-type":[{"value":"1015-3837","type":"print"},{"value":"1421-9964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,12,23]]}}}
