Vena cava filter
In medicine, vena cava filters, also called Greenfield filters, are "mechanical devices inserted in the inferior vena cava that prevent the migration of blood clots from deep venous thrombosis of the leg."[1]
Inferior vena cava filter reduces pulmonary embolism[2][3] and is an option for patients with an absolute contraindication to anticoagulant treatment (e.g., cerebral hemorrhage) or those rare patients who have objectively documented recurrent pulmonary emboli while on anticoagulation.
A superior vena cava filter can be used for upper extremity thrombosis; however, the median survival is approximately one month.[4][5] A retrievable filter has been used[6]; however, retrievable filters are infrequently retrieved.[7][8]
Clinical practice guidelines address the use of vena cava filters.[9][10]
Adverse effects
Vena cava filters are themselves potential foci of thrombosis.[11]
