Duplication of the inferior vena cava (IVC) has been reported in literature. This achieves clinical significance in the setting of lower extremity venous thromboembolism with a contraindication for anticoagulation. We describe a case of lower extremity deep vein thrombosis with duplicate IVC. Anticoagulation was contraindicated in this case leading to successful treatment with double IVC filters. We conducted a PubMed search for all current English language published literature, where filters were placed in the presence of duplicate IVC. We suggest that patients with deep vein thrombosis should have an accurate assessment of venous anatomy before IVC filter placement. Duplication of IVC, although rare, should be considered as this has management implications.
文献中已有关于下腔静脉（IVC）重复的报道。在存在抗凝禁忌的下肢静脉血栓栓塞情况下，这具有临床意义。我们描述了一例伴有重复IVC的下肢深静脉血栓形成病例。该病例抗凝治疗存在禁忌，因此成功采用了双IVC滤器进行治疗。我们在PubMed上搜索了所有当前以英文发表的文献，这些文献涉及在重复IVC情况下放置滤器的情况。我们建议，对于深静脉血栓形成患者，在放置IVC滤器之前应准确评估静脉解剖结构。IVC重复虽然罕见，但应予以考虑，因为这对治疗有影响。
