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。 Venous thromboembolism (VTE) is a common postoperative surgical complications, can increase postoperative mortality, affecting the prognosis of patients. Tumors, obesity, hypertension, diabetes mellitus, and surgical trauma are common risk factors for increased VTE in patients undergoing abdominal surgery. Effective preventive measures, including mechanical measures and the use of anticoagulants such as heparin, can significantly reduce the incidence of postoperative thrombotic complications in patients. Therefore, to clearly influence the risk factors of postoperative VET and to take effective preventive measures is very important to improve the prognosis of patients undergoing abdominal surgery.
