What is a prophylactic IVC filter?
A prophylactic IVC filter is placed in patients who are at an increased risk for, but do not currently have, DVT or PE. These filters are most commonly placed in patients who face prolonged immobilization. This population primarily consists of trauma patients with long bone or pelvic fractures and neurosurgical patients with transient or permanent motor deficits. Prophylactic filters may also be placed in patients with DVT risk factors before having surgery.
