Perforation of inferior vena cava (IVC) by filter struts ranges from 9% to 24%, and clinical sequelae and complications are unpredictable. The aim of this article was to report an unusual case of late complication of IVC filter that caused an IVC wall perforation and penetration of the filter's hooks in the aorta, which was treated by endovascular procedure. Molding strut tip by balloon angioplasty, its accommodation with a bare stent, and its coverage and protection with an endoprosthesis is probably the first technique reported so far in this situation.
滤器支杆导致下腔静脉（IVC）穿孔的发生率为9%至24%，其临床后遗症和并发症难以预测。本文旨在报告一例IVC滤器迟发性并发症的罕见病例，该并发症导致IVC壁穿孔以及滤器钩穿透至主动脉，通过血管内手术进行了治疗。通过球囊血管成形术塑造支杆尖端，使用裸支架使其适应，并用腔内假体进行覆盖和保护，这可能是迄今为止在这种情况下报道的首例技术。
