title: [Application of suprarenal inferior vena cava filter placement in patients with venous thromboembolism].
abstract: OBJECTIVE
  To evaluate the safety and efficacy of suprarenal inferior vena cava (IVC) filter implantation in patients with venous thromboembolism (VTE).
  
  
  METHODS
  Between May 2006 and December 2014, 28 patients with VTE underwent suprarenal IVC filter implantation, anticoagulant treatment and/or catheter-directed thrombolysis at the affiliated hospital of Xuzhou medical college. Follow up examination with color Doppler ultrasound was taken after treatment to eassess the patency of IVC.
  
  
  RESULTS
  One filter was successfully implanted in suprarenal IVC in each patient intraoperatively. The filter was retrieved in 26 patients after indwelling of 5 to 17 (mean 11 ± 3) days. The filter was permanently indwelled in 2 patients. There were no complications of filter tilt and migration in all cases. Twenty eight patients were followed up for 2 to 104 (mean 34 ± 34) months. None of the 2 patients whose filters were permanently indwelled presented complications of recurrent pulmonary embolism and IVC occlusion due to the filter. Among 26 patients whose filters were retrieved, the IVC was patent.
  
  
  CONCLUSIONS
  Suprarenal IVC filter placement is a safe and effective method in the treatment of VTE.
