Objective To assess the efficiency,safety and indications of permanent inferior vena cava filters (VCF) placement for prevention of pulmonary embolism in cases of deep vein thrombosis (DVT). Method In this study 71 cases were treated with permanent inferior vena cava filters by way of the internal jugular vein and the common femoral vein. Cavography was performed routinely before inserting the VCF to confirm no thrombosis in IVC and access veins. The insertion site for filters is the subrenal vena cava. Results The procedure was successful in all cases. There was no case of symptomatic PE occurred during 1~41 months of follow-up. There were 2 cases of IVC thrombosis at the site of insertion and 5 cases of filter tilting less than 15°. There were no other complications. Conclusion Permanent IVC filter placement is an effective method for preventing fatal PE due to DVT. Imaging of the vena cava and access vein by venous ultrasound and cavography, strict anticoagulation therapy after VCF insertion are key to perform VCF placement, provide protection from recurrent life-threatening PE and reduce complications. The filter placement indications should be strict.
