Inferior vena cava (IVC) filters are indicated in patients with venous thromboembolic disease in whom standard anticoagulation therapy is contraindicated or ineffective. A 32-year-old female presented to our hospital with chest pain 5 years after IVC filter placement. Imaging revealed sequential fracturing and embolization of two of the IVC filter arms to the pulmonary arteries. IVC filter fracture and subsequent migration to the lung is a rare complication. Systematic long-term follow-up in patients with IVC filters and, if possible, filter removal should be considered to prevent possible complications.
下腔静脉(IVC)滤器适用于存在静脉血栓栓塞性疾病且标准抗凝治疗禁忌或无效的患者。一名 32 岁女性在 IVC 滤器置入 5 年后因胸痛就诊于我院。影像学检查显示两个 IVC 滤器臂相继断裂并栓塞至肺动脉。IVC 滤器断裂并随后迁移至肺部是一种罕见的并发症。应对 IVC 滤器患者进行系统的长期随访,如果可能,应考虑取出滤器以预防可能的并发症。
