BackgroundIn the absence of a contiguous bowel perforation or intraabdominal source, infection of a retained vena cava filter in an occluded IVC has never been described.ObjectiveTo describe a case of an infected IVC filter in a chronically occluded iliocaval segment.MethodsHere we present a case of an immunosuppressed 35-year-old female with chronically occluded iliocaval stents and an extensive staphylococcus hominis infection of a previously endo-trashed Bard Eclipse® filter. Particular attention is paid to supportive imaging in establishing the diagnosis and technical aspects of successful device explant and retroperitoneal debridement.ResultsAt 6 months postoperatively, the patient was doing well without evidence of recurrent infection. Her lower extremity edema was controlled with compression alone.ConclusionsThe main objective of this operation was source control with debridement of the infection and removal of the filter and as much of the iliac vein as safely possible. Superinfection of a previously placed iliocaval stents and inferior vena cava filter remains a concern in patients with retroperitoneal infection and chronic iliocaval occlusion. Operative explant and debridement can be safely performed in patients with favorable cardiopulmonary risk.

免疫抑制患者的受感染、内腔内废弃的 IVC 过滤器的外植体，其髂腔支架长期闭塞

背景在没有连续肠穿孔或腹腔内来源的情况下，从未描述过闭塞的下腔静脉中保留的腔静脉过滤器的感染。目的描述一例慢性闭塞的髂腔静脉段中下腔静脉过滤器感染的病例。一名免疫抑制的 35 岁女性，患有长期闭塞的髂腔静脉支架，并且先前废弃的 Bard Eclipse® 过滤器出现广泛的人型葡萄球菌感染。在成功进行装置外植和腹膜后清创的诊断和技术方面，特别注意支持性影像学检查。结果术后 6 个月，患者状况良好，没有复发感染的证据。仅通过压迫即可控制她的下肢水肿。结论该手术的主要目的是通过清创感染和尽可能安全地去除过滤器和尽可能多的髂静脉来控制源头。先前放置的髂腔静脉支架和下腔静脉过滤器的重复感染仍然是腹膜后感染和慢性髂腔静脉闭塞患者的一个问题。对于心肺风险良好的患者，可以安全地进行手术外植体和清创术。
