lass=""h4"">Objectives

To assess whether the introduction of removable inferior vena cava filters (VCF) has led to variations in the number of implants, indications, and immediate complications in our hospital.

lass=""h4"">Materials and methods

The study included consecutive patients (n = 88, mean age 68 years, males 46 % ) with DVT (n = 27, 30.7 % ), PE (n = 22, 25 % ) or both (n = 39, 44.3 % ) who had a VCF implanted by vascular surgeons between 1996-2011. Since 2004 all VCF were potentially removable (OptEase / Cordis). Indications DVT / PE recurrent / progressive with proper anticoagulation (n = 22, 25 % ), DVT / PE with contraindication to anticoagulation (n = 47, 53.4 % ), or removal of anticoagulation after DVT / PE for major surgery (n = 19, 21.6 % ).

lass=""h4"">Results

A total of 88 VCF were implanted: 33 permanent (20 Venatech-LGM/Braun, 13 Trapesase / Cordis), and 55 removable (OptEase / Cordis). Since the introduction of removable VCF, the number of implants increased by 40 % , indications for anticoagulation after withdrawal of DVT / PE for major surgery increased (P = .001) and the indications for DVT / PE recurrent / progressive (P < .001) decreased. Thirty-one (65 % ) of supposedly temporary VCF (n = 48) were not removed. Removal was more likely if implanted in surgery (P < .001) and less if it was for DVT / PE recurrent / progressive (P < .06). There were no immediate complications associated with the procedure.

lass=""h4"">Conclusions

The availability of removable FVC has resulted in a higher number of implants, especially in patients with DVT / PE where anticoagulation should be discontinued for major surgery, and probably before that it was delayed until after the acute phase of PE / DVT. Although removable VCF are equally safe in the short term, a significant percentage of those with suspected temporary indications are eventually withdrawn, so its iindication should not be widened.
