摘要
Objectives The aim of this review is to focus on risk factors, risk-modifying drugs and prognosis for upper limb arterial thromboembolism, and the relationship between upper limb arterial thromboembolism and atrial fibrillation (AF). Methods We searched MEDLINE for studies on the epidemiology of upper limb thromboembolism from 1965 to June 2012. We also searched for contemporary, phaseIII randomized trial data on systemic (non-stroke) thromboembolism comparing warfarin with new oral anticoagulants (OACs) in patients with atrial fibrillation published after the year 1999. Results The incidence of upper limb thromboembolectomy was 3.3 per 100000 person-years among men and 5.2 per 100000 person-years among women; the risk of limb amputation, stroke and death after thromboembolectomy was increased. There was an increased risk of thromboembolectomy of the upper limb in patients with AF diagnosed with hypertension (hazard ratio [HR]2.22.9), myocardial infarction (HR2.93.9), heart failure (HR1.61.9), and stroke (HR2.23.8). For those diagnosed with diabetes mellitus, the risk was non-significantly increased by 1.21.4. Females had a 1.8-fold (95% confidence interval [CI]1.52.3) fold increased risk of thromboembolectomy as compared with men. The risk reduction for systemic embolism with new OACs as compared with warfarin in patients with AF is similar to that seen with warfarin (odds ratio0.79, 95%CI0.381.64). Conclusions Age, female sex, AF, hypertension, diabetes, myocardial infarction, heart failure and stroke are most common risk factors for thromboembolectomy of the upper limb. The availability of new OACs holds promise for reducing the risk of systemic thromboembolism, but specific data are still limited.
