Deep venous thrombosis after percutaneous insertion of vena caval filters

Abstract

There is a continuing and significant incidence of new DVT development ipsilateral to the percutaneous femoral insertion site of vena caval filters. The smaller diameter filters are not associated with a lower incidence of femoral thrombosis.

Retrievable inferior vena cava filters may be safely applied in gastric bypass surgery

“…IVC filters have been shown to prevent PE, but are associated with their own risks [7][8]. These include IVC erosion, perforation, migration, filter infection, filter occlusion, formation of thrombi proximal to the filter, insertion site trauma, and DVT [9][10][11]. The ideal intervention would be a temporary IVC filter that is removed perioperatively, once the patientÕs risk of VTE has diminished.…”

Implante profilático e temporário de filtro de veia cava inferior no trauma

“…The rate of removal of retrievable filters is still low, which can be attributed to the clinical conditions of multiple trauma patients and to failures by the services that implant filters to follow-up their patients afterwards 14 . Permanent vena cava filters offer high efficacy for prevention of PE, but are not themselves free from complications and there is a significant rate of thrombosis, which in turn can lead to severe post-thrombotic complications 15,16 . In view of this, temporary interruption of the vena cava with a filter appears to be the best option for preventing PE, particularly in cases in which full anticoagulation is contraindicated 17 .…”

The use of retrievable inferior vena cava filters in severely injured military trauma patients

“…21 It was interesting, however, that there were no other detected insertion site or de novo DVT. This has been estimated to occur in 3 to 40% of patients after IVCF placement, [22][23][24][25] but the etiology and subsequent clinical significance are unclear. These observations were made in mixed populations who may have had other risk factors for DVT, 22 and a majority were actually found bilaterally or in the contralateral lower extremity, 23 calling into question the direct relationship between the two events.…”
