Congenital TTP (cTTP, Upshaw\u2013Schulman syndrome) arises from biallelic mutations in the ADAMTS13 gene, leading to lifelong enzyme deficiency, often manifesting in childhood and requiring chronic plasma replacement. Pregnancy physiologically decreases ADAMTS13 activity, predisposing affected women to relapses and adverse outcomes if untreated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation<\/jats:title>\n                    <jats:p>We report a case of a 32\u2010year\u2010old Iranian woman with childhood\u2010onset cTTP managed with long\u2010term fresh frozen plasma (FFP) prophylaxis. After two early miscarriages, her regimen was intensified to FFP every 10 days. During her third pregnancy, ADAMTS13 monitoring was limited, so surrogate markers (platelet count and lactate dehydrogenase) guided therapy. In the third trimester, when ADAMTS13 reached the lower normal limit, FFP was increased to weekly. She delivered a healthy male infant (3200\u00a0g, Apgar 8\/10) at 37 weeks\u00a0+\u00a04 days via cesarean section, complicated only by diet\u2010controlled gestational diabetes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This case highlights that individualized FFP prophylaxis can enable successful full\u2010term pregnancy in cTTP even in resource\u2010limited settings lacking ADAMTS13 testing. Reliance on clinical and hemolysis markers offers a practical alternative for monitoring. Prophylactic plasma replacement remains essential to prevent relapses and optimize maternal\u2010fetal outcomes in cTTP pregnancies.<\/jats:p>\n                  <\/jats:sec>\n
