Vena cava filters: a nursing perspective.

Healthcare professionals increasingly are using vena cava filters to prevent pulmonary emboli (PE) in patients with cancer. Patients with cancer are predisposed to developing thrombosis and subsequent PE for a variety of reasons. These patients commonly have contraindications to anticoagulant therapy because of their disease or cancer treatment; therefore, vena cava filters are an appealing option for managing potential emboli. This article describes the etiologies of thrombosis in patients with cancer; problems associated with conventional anticoagulant therapy; vena cava filters and placement procedures; complications associated with filter placement; and related nursing implications pre- and postinsertion and during long-term follow-up.
