Extensive work-up provided no evidence of predisposing factors for arterial thrombosis. Infiximab was thus suspected in the genesis of throm-bosis, based on both intrinsic and extrinsic criteria. At month 3 after thrombosis with ongoing anticoagulation, angio-tomodensitometry showed complete revascularization of the left renal artery with renal atrophy. Renal function remained normal and the patient was still in steroid free remission on mercaptopurin monotherapy at maximal follow-up. Few thromboembolic events have been described with anti- tumor necrosis factor （TNF） agents, but it is the frst case reported of renal artery thrombosis after infiximab infusion. In addition, we re-view thrombosis associated with anti-TNF agents.展开更多

Typical clinical presentations of ARAO are non-specific and include acute lumbar or abdominal pain coexisting with nausea, vomiting and fever. Peripheral emboli are the major cause of ARAO, predominantly arising from cardiac diseases. Other, relatively frequent causes of ARAO include atherosclerosis, trauma, dissection or renal artery aneurysms.展开更多
