Antiphospholipid syndrome is accepted as one of the most important causes of hypercoagulable states. Thrombotic events in patients with antiphospholipid syndrome, predominantly women, occur at a younger age than in those suffering from atherosclerotic disease. The majority of the thrombotic events affect the deep venous system of the lower limbs and arterial thrombosis predominates in the cerebral territory. The use of anticoagulant therapy prevents recurrent thrombosis but the duration and intensity of treatment remain controversial. Aortic disease is an anecdotal fact in the literature. A case of infrarenal aortic occlusion involving both iliac arteries associated with primary antiphospholipid syndrome is presented.
