Acute limb ischemia is a rare condition in patients with venous thromboembolism (VTE), who
already receive anticoagulation treatment. Inflammation is a risk factor for thrombus formation. Patients with active ulcerative colitis, especially at time of exacerbation, are more prone to thromboembolism, both venous and arterial. Risk for thrombosis is 18% higher risk, with also higher risk of bleeding. Up 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 (UC) exacerbation, hospitalized initially for pulmonary thromboembolism, that developed acute arterial thrombosis when switched on novel oral anticoagulant (NOAC).
