静脉血栓栓塞症（VTE）是外科常见的手术后并发症，可增加术后病死率，影响病人预后。肿瘤、肥胖、高血压病、糖尿病以及手术创伤等是增加腹部手术病人VTE发生的常见危险因素。而有效的预防措施，包括机械性措施以及肝素等抗凝药物的应用能够显著降低病人术后血栓性并发症的发生率。因此，明确影响病人术后VET发生的危险因素，并采取有效的预防措施对改善腹部手术病人的预后是非常重要的。

Abstract    Venous thromboembolism (VTE) is one of the most common post-operative complications in patients undergoing abdominal surgery, it causes more deaths and worsens the outcomes of the patients. Including malignancy, obesity, hypertension, diabetes and traumas caused by operations are the most common risk factors of VTE. Effective prophylaxis including mechanical methods and anticoagulants heparin, can markedly reduce the incidence of VTE. So it is very important for surgeons to be aware of the risk factors and make sufficient measures against VTE to improve the outcomes of the patients undergoing abdominal surgery.
