Inferior vena cava filters are increasingly used in patients with recurrent venous thromboembolism who are contraindicated to anticoagulation. Migration of a broken strut to the pulmonary artery is a very rare complication of these filters. We report the case of an 83-year-old female who experienced this complication with the migratory strut remaining in the same position for years. This case provides evidence that such filters probably have higher rates of complications than what has been thought that remain asymptomatic. The indications and the management of complications of such devices need to be studied further.

下腔静脉滤器越来越多地用于对抗凝治疗有禁忌证的复发性静脉血栓栓塞患者。滤器断裂支杆迁移至肺动脉是这些滤器非常罕见的并发症。我们报告了一例83岁女性发生这种并发症的病例，迁移的支杆多年来一直停留在同一位置。该病例证明，此类滤器可能比人们认为的有更高的并发症发生率，且这些并发症仍无症状。此类装置的适应证及并发症的处理需要进一步研究。
