目的：评价G2下腔静脉滤器的可取性及影响其安全性和技术成功率的因素。材料与方法：自2006年10月至2008年6月，对140例需要预防肺栓塞的患者放置G2下腔静脉滤器。滤器放置的一般指征包括血栓栓塞病史(n=98)和PE高危(n=42)；特殊指征包括抗凝禁忌症(n=120)、抗凝预防(n=16)和抗凝失败(n=4)。结果：26例患者(男性12例，年龄24~88岁；平均年龄55.4岁)在平均122天(11~260天)后进行了27次G2期滤器取出手术。数据是在机构审查委员会批准后进行回溯性收集的。所有27次尝试均成功去除滤器(100%)。滤器倾斜(15度)5例(18.5%)，滤器可能合并于下腔静脉右侧壁1例。未发生滤器血栓形成、滤器明显移位、滤器断裂、腔静脉阻塞等并发症。结论：G2下腔静脉滤器取出术技术成功率高，并发症发生率低。技术成功似乎不受报告范围内的停留时间的影响。
PURPOSE: To assess the retrievability of the G2 inferior vena cava (IVC) filter and factors influencing the safety and technical success of retrieval.MATERIALS AND METHODS: From October 2006 through June 2008, G2 IVC filters were placed in 140 consecutive patients who needed prophylaxis against pulmonary embolism (PE). General indications for filter placement included history of thromboembolic disease (n = 98) and high risk for PE (n = 42); specific indications included contraindication to anticoagulation (n = 120), prophylaxis in addition to anticoagulation (n = 16), and failure of anticoagulation (n = 4). Filter dwell time, technical success of filter retrieval, and complications related to placement or retrieval were retrospectively evaluated in patients who underwent filter removal.RESULTS: Twenty-seven attempts at G2 filter removal were made in 26 patients (12 men; age range, 24-88 years; mean age, 55.4 y) after a mean period of 122 days (range, 11-260 d). Data were collected retrospectively with institutional review board approval. Filter removal was successful in all 27 attempts (100%). Tilting of the filter (>= 15 degrees) occurred in five cases (18.5%), with probable filter incorporation into the right lateral wall of the IVC in one. Other complications of retrieval such as filter thrombosis, significant filter migration, filter fracture, and caval occlusion were not observed.CONCLUSIONS: G2 IVC filter retrieval has a high technical success rate and a low complication rate. Technical success appears to be unaffected by the dwell time within the reported range.
