Acute arterial thrombosis in anticoagulated patient for acute pulmonary thromboembolism

Abstract

Acute limb ischemia is rare in patients with venous thromboembolism who already receive anticoagulation treatment. Inflammation is a risk factor for thrombus formation. Patients with active ulcerative colitis, especially at the time of exacerbation, are more prone to thromboembolism, both venous and arterial. The risk for thrombosis is 18% higher, with a higher risk of bleeding. To date, there is no contraindication to any anticoagulant drug in patients with ulcerative colitis. We represent a case of a 73 year - old woman with ulcerative colitis exacerbation, hospitalized initially for pulmonary thromboembolism, that developed acute arterial thrombosis when switched on a novel oral anticoagulant.
