Carlos Veríssimo, Teresa Matos, Luís Dutschman, Isilda Rocha


Antiphospholipid Syndrome (APS) is an immune thrombophylia of unknown etiology which leads to vascular thrombosis and gestational complications.A 27-year old woman who had been diagnosed APS four years before was admitted in the Emergency Room five days after a spontaneous delivery due to [corrected] pain in the upper right abdominal quadrant. Blood analysis revealed AST and ALT rise and thrombocytopenia. CT scan was suggestive of liver infarction due to venous ischemia.
