ABSTRACTIntroduction: In 1973, Greenfield designed a device to block the return venous flow of the lower vena cava. Since then several types of Vena Cava Filters (VCF) have been developed, which are currently applied by percutaneous access. There are very precise indications for applying a vena cava filter, such as: recurring pulmonary thromboembolism (PTE), patients subject to embolectomy, prophylaxis in cancer patients, with some kind of trauma, with acetabular fractures, knee surgeries and wide burnings. There are three types of VCF: permanent, temporary and removable or recoverable. Material and Method: The exact guidelines for applying a VCF are described in this review, along with their types and complications.
Discussion: There have been important developments in the application of VCF, the most important being the percutaneous access and performing a cavography prior to applying the filter. Currently, we have VCF that are every time more flexible and that can be applied by means of devices with smaller gages which enable access through ways other than the femoral or jugular veins.
Conclusions: VCFs are an excellent alternative for blocking the vascular flow of the lower Vena Cava in those cases where there is a predisposition to forming thrombus in the lower limbs. Percutaneous application and planning uch application by jeans of a previos cavography improves the result. Currently there are filters that can be recovered, extending the possibility of their application in young patients.
