Inferior Vena Cava Filter

Aka: Inferior Vena Cava Filter, Vena Cava Filter, IVC Filter, Greenfield Filter
  1. Indications: Prevent embolism in Deep Vein Thrombosis
    1. Anticoagulation contraindicated (Fall risk, Bleeding risk)
      1. High risk Hypercoagulable patients or
      2. High risk of Pulmonary Embolism (e.g. proximal DVT)
        1. Prolonged bed-bound status (e.g Trauma, paralysis, Severe Head Injury, Hip Fracture, Pelvic Fracture, Bariatric Surgery)
    2. Complication secondary to Anticoagulation
      1. Failed Anticoagulation
        1. Deep Vein Thrombosis extension
        2. Pulmonary Embolism despite Anticoagulation with therapeutic levels
      2. Hemorrhage
      3. Thrombocytopenia
      4. Warfarin skin necrosis
      5. Noncompliance with Anticoagulation protocol
  2. Efficacy
    1. Lower Incidence of Pulmonary Embolism
    2. Does not reduce overall mortality

  3. Complications
    1. Overall complication rate: 1-2%
    2. Early complications
      1. Malpositioned IVC Filter (e.g. tilted)
      2. Insertion site hematoma
      3. Deployment complication (e.g. filter fails to open completely)
    3. Late complications
      1. IVC Filter migration (e.g. into right atrium or superior vena cava)
      2. IVC Filter tilted or otherwise malpositioned
      3. IVC thrombosis
      4. IVC perforation (e.g. due to IVC Filter leg or strut fracturing)
        1. Retroperitoneal hematoma
        2. Aortic pseudoaneurysm
        3. Duodenal perforation
        4. Pancreatic injury
        5. Vertebral body injury
        6. Iliopsoas muscle injury

  4. Precautions
    1. IVC Filters should only be used as bridging devices until risk of Pulmonary Embolism wanes
    2. FDA recommends removal of IVC Filter when no longer indicated
      1. However removal is difficult and fails in up to 8% of cases

Vena Cava Filters (C0080306)

Definition (SPN) A cardiovascular intravascular filter is an implant that is placed in the inferior vena cava for the purpose of preventing pulmonary thromboemboli (blood clots generated in the lower limbs and broken loose into the blood stream) from flowing into the right side of the heart and the pulmonary circulation.
Definition (MSH) Mechanical devices inserted in the inferior vena cava that prevent the migration of blood clots from deep venous thrombosis of the leg.
