In patients with acute PE, if anticoagulant therapy is not possible because of risk of bleeding, we recommend placement of an inferior vena caval filter (Grade 1C).

MethodsThe implantation of vena caval filter was performed in 30 patients with DVT of lower extremities. A permanent filter was used in 14 cases, and temporary filter in 16. Of the 30 cases, 27 received venous thrombolysis or thrombectomy combined with interventional thrombolytic therapy.

30例下肢深静脉血栓形成的病人，14例植入永久性腔静脉滤器，16例植入临时性腔静脉滤器；27例分别行单纯静脉溶栓或切开取栓+静脉置管溶栓；全部病例同时行抗凝治疗。

Temporary filters detained in vena cava for 26-40 days. One patient had recurrent PE two days after removal of the filter. Two patients with permanent filter presented inferior vana caval occlusion at six and 14 months, respectively.

临时滤器在体内留置时间26～40 d，1例取出后2 d出现复发性肺栓塞；2例永久性滤器植入者于6个月和14个月出现下腔静脉堵塞。
