title: [Clinical treatment of application of deep venous thrombosis by retrievable vena cava filter].
abstract: OBJECTIVE
  To summarize the clinical experiences of treating deep venous thrombosis (DVT) with retrievable vena cava filter.
  
  
  METHODS
  A total of 180 patients with DVT in unilateral lower extremity were recruited. There were 82 males and 98 females with an average age of 46 years old. After the diagnosis of vascular color Doppler ultrasound, retrievable vena cava filter was implanted through contralateral femoral vein. Simultaneously another 114 patients underwent femoral vein embolectomy. All cases received the post-operative therapies of anticoagulation, thrombolysis and vasodilation.
  
  
  RESULTS
  The implantation of retrievable vena cava filter was successful in all cases. Among 142 cases of attempted extraction, 116 filters were extracted successfully at Days 12 - 24. The success rate was 81.69%. Filters captured thrombosis in 34 cases (29.31%).
  
  
  CONCLUSIONS
  As a safe and efficacious method, the implantation of retrievable vena cava filter prevents the occurrence of pulmonary embolism in the patients with DVT in unilateral lower extremity. Its timely extraction may avoid the long-term complications.
