ABSTRACT
Introduction: 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.
