Pulmonary embolism (PE) is a common and feared result of deep vein thrombosis. While anticoagulation is the mainstay of management, interruption of flow of thrombus from leg veins to the pulmonary circulation is frequently desired either in lieu of or in addition to anticoagulation. Inferior vena cava filters have become frequently used to prevent PE despite a paucity of evidence for efficacy and increasing concerns about the long-term complications of indwelling filters.
肺栓塞（PE）是深静脉血栓的常见且可怕的后果。虽然抗凝是管理的主要方法，但无论是替代抗凝还是在抗凝之外，通常都希望阻止血栓从腿部静脉向肺循环流动。尽管缺乏疗效证据，并且对留置过滤器的长期并发症的担忧日益增加，但下腔静脉过滤器的使用仍越来越频繁。
