[Indications for the implantation of a vena cava filter]

Abstract

Intracaval filter implantation is an alternative to surgical removement of the sources of pulmonary emboli. The indication for implantation of a Greenfield vena cava filter, which is the far advanced type, has to be a very narrow one, however. The two main indications are: recurrent emboli despite adequate anticoagulant therapy and contraindications to anticoagulation and no possibility for venous thrombectomy or thrombolytic therapy. Venous disobliteration by surgical (thrombectomy) or medical (streptokinase) means remains the therapy of choice.
