目的    探讨外科手术后肺栓塞的诊断、治疗和预防方法。方法    对2006年 10月至 2010年 9月中国医科大学附属盛京医院普外科13例术后肺栓塞病人的诊治过程进行分析，探讨术后应用低分子肝素预防肺栓塞的经验。 结果    13例中10例明确诊断，3例误诊。10例存活，3例死亡。2009年8月始对术前肺栓塞风险评估为中度风险以上的病人，术后应用低分子肝素行预防性抗凝治疗，无肺栓塞新发病例。 结论    普外科手术后应警惕肺栓塞的发生。对可疑病例应力争早期诊断、早期治疗。术前对病人进行肺栓塞风险评估，术后及时应用低分子肝素预防肺栓塞是非常必要的。

Abstract    Objective    To study the diagnosis, treatment and prevention of postoperative pulmonary embolism and reduce the incidence. Methods    The diagnosis and treatment procedures of 13 patients with postoperative pulmonary embolism admitted between October 2006 and September 2010 in the Department of General Surgery of Shengjing Hospital Affiliated to China Medical University were analyzed. Some experiences of preventing pulmonary embolism by using low molecular heparin were explored. Results    Ten of 13 pulmonary embolism patients were diagnosed and 3 patients were misdiagnosed. Ten patients survived and 3 patients died. There was no pulmonary embolism happened in patients who were evaluated middle or more risk because of using low molecular heparin after August 2009. Conclusion    Pulmonary embolism after operation should be valued. Early diagnosis and treatment are the keys for suspicious patients. Evaluating risk before operation and using low molecular heparin after operation are necessary to prevent pulmonary embolism.
