She presented with severe thrombocytopenia, haemolysis, hypertension and neurological symptoms. Laboratory findings, including microangiopathic haemolytic anaemia, elevated lactate dehydrogenase (LDH) and a severely reduced <jats:italic>ADAMTS13<\/jats:italic> activity, confirmed the diagnosis. Genetic testing identified a mutation in the <jats:italic>ADAMTS13<\/jats:italic> gene. The patient was managed with plasma exchange (PLEX), fresh frozen plasma (FFP) and supportive care. After two sessions of PLEX, her platelet count increased to 150 \u00d7 10\u2079\/L, LDH normalised, blood pressure stabilised and antihypertensive medications were discontinued. At discharge, she was asymptomatic, with a creatinine of 0.6\u2009mg\/dL. Follow-up at 3 and 6\u2009months showed no recurrence. This case highlights the importance of early recognition of TTP in pregnancy, differentiation from other pregnancy-related disorders and the role of genetic testing in guiding long-term management and counselling.<\/jats:p>","DOI":"10.1136\/bcr-2025-265735","type":"journal-article","created":{"date-parts":[[2025,8,12]],"date-time":"2025-08-12T02:30:27Z","timestamp":1754965827000},"page":"e265735","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Severe
