Abstract
Antiphospholipid antibody syndrome is a thrombophilia characterized by the association of a clinical or obstetric arterial and/or venous thromboembolic event with persistent antiphospholipid antibodies. We here report the case of a young patient admitted with acute renal failure associated with bilateral renal artery thrombosis. Immunology tests showed lupus-like circulating anticoagulant on the basis of which the diagnosis of antiphospholipid antibodies was retained. Early angioplasty was performed enabling renal function recovery.
