背景：在血管内治疗下肢深静脉血栓形成(DVT)的过程中，是否暂时使用滤器存在较大争议。目的：评价各种血管内技术治疗DVT时植入可回收的下腔静脉滤器的必要性。材料和方法：2001年4月至2006年10月，对34例有症状的DVT患者进行了连续37次血管内治疗。所有治疗过程中均植入Gunther郁金香可回收腔静脉滤器(GTF)。结果：37例次共成功植入66枚GTF。所有患者均避免了肺栓塞的恶化或新的形成。在37次治疗中，有20次(54.1%)观察到滤器内有血栓。14例血栓较大，占滤器高度的一半以上。结论：滤器临时置入可有效预防下肢深静脉血栓血管内治疗中肺血栓的形成。
Background: There is strong controversy as to whether to use filters temporarily in the inferior vena cava (IVC) during endovascular therapies for deep venous thrombosis (DVT) in the lower extremity.Purpose: To evaluate the necessity of implantation of a retrievable inferior vena cava filter during treatment of DVT in the lower extremity using various endovascular techniques.Material and Methods: Studied were all 37 consecutive sessions of endovascular treatments performed in 34 patients with symptomatic lower-limb DVT between April 2001 and October 2006. In all sessions, a Gunther tulip retrievable vena cava filter (GTF) was implanted during the procedures. The degree of trapped thrombus in the filter was evaluated by repeated venocavography.Results: Implantation of a total of 66 GTFs was successfully performed in 37 sessions. Worsening of or new formation of pulmonary embolism was avoided in all patients. In 20 (54.1%) of the 37 sessions, a trapped thrombus in the filter was observed. In 14, the trapped thrombus was large, filling more than half the height of the filter.Conclusion: Temporary implantation of filters is effective in preventing pulmonary emboli during endovascular treatment of DVT in the lower extremities.
