ABSTRACT

Introduction: Vena cava filters are special metallic devices designed specially to be placed in the inferior cava vein in view of imminent risk of pulmonary tromboembolism by deep venous thrombosis.
Objective: To update the state of vena cava filters and their placement.
Methods: A bibliographic review was carried out in the years 2010 to 2016 in Medline, Cochrane Library and Lilacs data bases, as well as in Google search engine. There were consulted cohort, prospective, retrospective, clinical and epidemiological studies, meta-analysis, bibliographic reviews and clinical trials.
Results: Vena cava filters were described and used for the first time in 1967 in the United States of America. The filters can be placed percutaneously and produce a partial mechanical disruption of the inferior cava vein flow. There are 3 kinds of filters in the market: permanent, temporal and mixed. The key factors of a filter are clot trapping capacity, access to the vena cava and occlusion capacity; also embolization, mechanical integrity grade, and placement feasibility. Complications by the filter may occur immediately or in a long term, with an average of 0, 3% in major complications, and less than 0,2% of mortality rate due to the placement of the filter.
Conclusion: In spite of its proven benefits, there is not existence in Cuba of publications that guarantee its use. Because of its importance and resolvent capacity, it is suggested that this technique should start to be usually used in secondary and tertiary level hospitals in Cuba.
