We aimed to characterize the prevalence and types of hypertensive disorders diagnosed in pregnancies with non\u2010immune hydrops fetalis and single effusions, as well as to investigate fetal risk factors for the development of hypertension.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a secondary analysis of a prospectively enrolled cohort. We included pregnancies with non\u2010immune hydrops fetalis that demonstrated \u22652 fetal effusions (ascites, pleural effusion, pericardial effusion, and\/or skin edema), as well as pregnancies with only one of these effusions. We excluded pregnancies that did not continue beyond 20 weeks gestation as most hypertensive disorders of pregnancy develop after this. Primary outcomes were the prevalence and types of hypertensive disorders diagnosed during pregnancy or within 6 weeks postpartum. Secondary outcomes were the prevalence of hypertensive disorders by number of fetal effusions and presence of an underlying fetal genetic disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among 116 pregnancies with fetal effusions, 22 (19%) developed hypertensive disorders of pregnancy, with 22% (19\/85) and 10% (3\/31) of pregnancies with non\u2010immune hydrops fetalis and single effusions affected, respectively (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.12). Of those with hypertensive disorders, 8 (36%) developed preeclampsia with severe features, 4 (18%) preeclampsia without severe features, 2 (9%) atypical preeclampsia, and 8 (36%) gestational hypertension; 82% of these diagnoses were made antepartum. The presence of a fetal genetic disease did not result in statistically significant increased risk of hypertensive disorders.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In this contemporary cohort that continued beyond 20 weeks gestation, 22% with non\u2010immune hydrops fetalis and 10% with single effusions developed a range of hypertensive disorders of pregnancy, with most arising in the antepartum period. These data allow clinicians to provide more evidence\u2010based counseling, anticipate obstetric risks, and consider close surveillance strategies for the development of hypertensive disorders in pregnancies with fetal effusions.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pmf2.70072","type":"journal-article","created":{"date-parts":[[2025,7,3]],"date-time":"2025-07-03T09:39:02Z","timestamp":1751535542000},"source":"Crossref","is-referenced-by-count":0,"title":["Risk of hypertensive disorders in pregnancies with non\u2010immune hydrops fetalis and single fetal effusions"],"prefix":"10.1002","volume":"1","author":[{"given":"Natalie B.","family":"Gulrajani","sequence":"first","affiliation":[{"name":"School of Medicine University of California  San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diana C.","family":"Robles","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences University of California San Francisco  San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan M.","family":"Gonzalez","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences University of California San Francisco  San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mary E.","family":"Norton","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences University of California San Francisco  San Francisco California USA"},{"name":"Institute for Human Genetics University of California  San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teresa N.","family":"Sparks","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences University of California San Francisco  San Francisco California USA"},{"name":"Institute for Human Genetics University of California  San Francisco California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,7,3]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2014.12.018"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00006254-199112000-00001"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00006254-199705000-00023"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12884-021-04143-3"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/01443615.2020.1718621"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1080\/14767058.2017.1396312"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.3109\/10641950903323244"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/apa.15260"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1159\/000305096"},{"issue":"16","key":"e_1_2_11_11_1","first-page":"2630","article-title":"Clinical Characteristics of Mirror Syndrome: A Comparison of 10 Cases of Mirror Syndrome with Non\u2010Mirror Syndrome Fetal Hydrops Cases","volume":"29","author":"Hirata G.","year":"2016","journal-title":"Journal of Maternal\u2010Fetal & Neonatal Medicine"},{"key":"e_1_2_11_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajogmf.2023.101067"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1055\/a\u20102008\u20102495"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa2023643"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.23652"},{"key":"e_1_2_11_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/cge.14309"},{"key":"e_1_2_11_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.24911"},{"issue":"2","key":"e_1_2_11_18_1","first-page":"e21","article-title":"Hypertension in Pregnancy: Diagnosis, Blood Pressure Goals, and Pharmacotherapy: A Scientific Statement from the American Heart Association","volume":"79","author":"Garovic V.
