[Case report: acute infrarenal aortic occlusion and leg vein thrombosis in heparin-induced thrombocytopenia].

Heparinassociated thrombocytopenia has been reported for over 35 years. This reaction can result in serious thromboembolic complications. The primary mechanism responsible for this reaction is thought to be an immunologic process. The author reports a severe thrombocytopenia, acute thrombotic occlusion of the leg, acute aortal thrombosis, deep-vein thrombosis and pulmonary emboli occurred simultaneously in a 75-year-old woman within 11 days of starting a subcutaneous low-dose heparin prophylaxis.
