Her indirect Coombs test was positive for anti-Jr&lt;sup&gt;a&lt;\/sup&gt; antibody (1:64). At 33 weeks\u2019 gestational age, we observed that fetal growth was mildly restricted and the peak systolic velocity of the fetal middle cerebral artery (PSV-MCA) was above the upper limit of the reference range (1.55 multiples of the median). Amniocentesis was also carried out and the \u0394OD450 value was in the lower mid-zone of the Liley curve. We continued to carefully observe the patient because we observed PSV-MCA values within 1.50\u20131.60 multiples of the median and no other findings of fetal anemia. She vaginally delivered a female infant weighing 2,136 g at 37 weeks\u2019 gestational age. The infant received treatment with both iron and recombinant erythropoietin without developing hyperbilirubinemia and blood transfusion. &lt;i&gt;Conclusion:&lt;\/i&gt; PSV-MCA should be monitored for the detection of fetal anemia, even in pregnant women sensitized to some antigens for which only routine obstetrical care is recommended.<\/jats:p>","DOI":"10.1159\/000259724","type":"journal-article","created":{"date-parts":[[2009,11,24]],"date-time":"2009-11-24T08:28:15Z","timestamp":1259051295000},"page":"81-83","source":"Crossref","is-referenced-by-count":14,"title":["Successful Management of Anti-Jr&lt;sup&gt;a&lt;\/sup&gt; Alloimmunization in Pregnancy: A Case Report"],"prefix":"10.1159","volume":"69","author":[{"given":"Akio","family":"Masumoto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hisashi","family":"Masuyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yumi","family":"Sumida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomonori","family":"Segawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuji","family":"Hiramatsu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,11,19]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1423-0410.1978.tb02932.x"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1537-2995.1978.18579036387.x"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1423-0410.1981.tb01010.x"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1620%2Ftjem.145.97"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1159%2F000091354"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1056%2FNEJM200001063420102"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajog.2005.06.078"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1067%2FS0002-9378%2803%2900771-3"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1136%2Fbmj.2.5365.1107"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1097%2FAOG.0b013e31817d453c"}],"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/259724","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/259724","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T21:24:30Z","timestamp":1745443470000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000259724"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,11,19]]},"references-count":10,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2010,3,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000259724","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,11,19]]}}}
