Of the three survivors who developed thrombosis during their hospital stay, only one (with pulmonary artery thrombosis, cerebral artery thrombosis, and microthrombosis) tested positive for aPLs: triple positive (for aCL IgG, anti-β2GPI IgM, and aPS/PT IgM) at admission, double (for aCL IgG and aPS/PT IgM) at discharge, and double (anti-β2GPI IgM and aPS/PT IgM) at follow-up (Table 4). Here, ACLY is linked to deep vein thrombosis.
