Permanent inferior vena cava (IVC) filters are used to prevent venous thromboembolic events in select populations of patients. The Bird's Nest filter (BNF; Cook Medical, Bloomington, Ind) is an IVC filter that has been associated with various complications including filter strut fractures, migration, caval wall perforation, visceral perforation, and vascular injury. We report a case of a BNF that eroded transmurally through the IVC into the right kidney parenchyma. The patient underwent operative intervention with removal of the BNF with an uncomplicated postoperative course. In patients with symptoms and local filter perforations, we advocate for safe filter removal when possible to avoid long-term damage.
永久性下腔静脉（IVC）滤器用于预防某些特定患者群体的静脉血栓栓塞事件。Bird's Nest 滤器（BNF；库克医疗，印第安纳州布鲁明顿）是一种 IVC 滤器，已与各种并发症相关联，包括滤器支柱断裂、迁移、腔静脉壁穿孔、内脏穿孔和血管损伤。我们报告了一例 BNF 经 IVC 壁穿透至右肾实质的病例。该患者接受了手术干预，成功取出了 BNF，术后过程顺利。对于有症状和局部滤器穿孔的患者，我们主张在可能的情况下安全地取出滤器，以避免长期损害。
