Popis: | Acute myelogenous leukemia (AML) is a malignant disease of the hematopoietic system, characterized by features of bone marrow insufficiency and organ infiltration by leukemic cells. Venous thrombosis in AML patients is uncommon, compared to bleeding; therefore in patients with AML, simultaneous occurrence of venous and arterial thrombosis is a rather rare presentation. We reported an unusual case of anti-phospholipid antibody syndrome secondary to AML characterized by venous and arterial thrombosis. A 70-year-old man with deep venous thrombosis (DVT) of the left leg confirmed by Doppler was seen in our clinic. During treatment with a Vitamin K antagonist (3 mg daily of Warfarin) and a low molecular weight heparin (LMWH), he developed an acute pulmonary embolism and an acute inferior wall ST elevation myocardial infarction (STEMI), a result of right coronary artery embolism. His full blood count showed leukocytosis and thrombocytopenia. Lupus anticoagulant and anti-cardiolipin antibodies were positive. A bone marrow aspirate test showed results consistent with AML (FAB class M1). A diagnosis of antiphospholipid antibody syndrome secondary to AML characterized by coronary artery embolism, pulmonary embolism and left leg DVT was eventually established. He received anticoagulation with a low dose of warfarin after refusing chemotherapy. He however died of cerebral hemorrhage despite the fact that the INR was in the normal therapeutic range. It is challenging to anticoagulated AML patients complicated by multiple vascular thromboses and thrombocytopenia. |
