We routinely screen all patients at the second\u2010trimester anatomy scan by transabdominal ultrasound identification of the placental cord insertion and a color flow Doppler sweep over the cervix. We also routinely perform transvaginal ultrasound with color flow Doppler in all patients with a second\u2010trimester low\u2010lying placenta or placenta previa. We confirm all diagnoses in the third trimester, at approximately 32\u2009weeks' gestation. Patients with VP were identified from the ultrasound and hospital databases. The primary outcome was perinatal survival in the screened patients, and we also compared neonatal outcomes between patients delivered &lt;\u200936 or \u2265\u200936\u2009weeks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>There were 205 patients (189 singleton and 16 twin gestations) with prenatally diagnosed VP during the study period. Resolution occurred in 25 (12.2%) patients, and delivery records were unavailable for six, leaving 174 patients with unresolved VP at delivery, all of whom were diagnosed prenatally. To our knowledge, there were no false\u2010positive or false\u2010negative diagnoses. All patients underwent Cesarean delivery, at a median gestational age of 35.1 (interquartile range, 34.6\u201335.9)\u2009weeks. All except one of the pregnancies resulted in live birth. The single death occurred in one of a set of monochorionic diamniotic twins that underwent laser photocoagulation for twin\u2013twin transfusion syndrome. Delivery \u2265\u200936\u2009weeks resulted in improved neonatal outcomes when compared with patients delivering &lt;\u200936\u2009weeks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study found almost universal perinatal survival in cases of prenatally diagnosed VP in a center with routine screening protocols for VP. These findings strongly support the implementation of a screening program for VP, which has the potential to significantly reduce the high rate of stillbirth associated with this condition. We do not, however, recommend delivery after 37\u2009weeks' gestation. \u00a9 2025 International Society of Ultrasound in Obstetrics and Gynecology.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/uog.29268","type":"journal-article","created":{"date-parts":[[2025,6,26]],"date-time":"2025-06-26T08:14:44Z","timestamp":1750925684000},"page":"194-199","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Vasa previa screening, diagnosis, management and outcomes: single\u2010center study"],"prefix":"10.1002","volume":"66","author":[{"given":"T.","family":"Lueck","sequence":"first","affiliation":[{"name":"Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology Beth Israel Deaconess Medical Center  Boston MA USA"},{"name":"Harvard Medical School  Boston MA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Macharia","sequence":"additional","affiliation":[{"name":"Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology Beth Israel Deaconess Medical Center  Boston MA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Modest","sequence":"additional","affiliation":[{"name":"Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology Beth Israel Deaconess Medical Center  Boston MA USA"},{"name":"Harvard Medical School  Boston MA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
