Diagnosis of catastrophic antiphospholipid syndrome was made and treated with IV steroids, heparin infusion and double filtration plasmapheresis (DFPP) without fresh frozen plasma. Heparin-induced thrombocytopaenia was second diagnosed because of persistent severe thrombocytopaenia after 2\u2009weeks of treatment associated with positive conversion of antibodies against platelet factor 4, and a positive functional assay. The clinical course was complicated by cerebellar haematomas that appeared a few days after the last session of DFPP. Heparin-induced thrombocytopaenia was managed by administration of argatroban, a direct thrombin inhibitor with an increase in platelet count. Neurologically, the patient recovered completely and was discharged on vitamin K antagonist treatment and regular dialysis.<\/jats:p>","DOI":"10.1136\/bcr-2019-231161","type":"journal-article","created":{"date-parts":[[2019,9,16]],"date-time":"2019-09-16T21:07:25Z","timestamp":1568668045000},"page":"e231161","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["A
