Vena cava filters offer a safe and effective prophylactic option for patients at high risk of pulmonary embolism when anticoagulation is not feasible. This study supports their justified use in select high-risk cases.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Cardiology

Background:

  • Historically, vena cava filters were reserved for recurrent pulmonary emboli in anticoagulated patients or those with contraindications to anticoagulation.
  • Recent trends show increased use for prophylaxis in patients with extensive deep vein thrombosis and contraindications to anticoagulation.

Purpose of the Study:

  • To evaluate the morbidity and effectiveness of vena cava filter insertions.
  • To determine if increased utilization of caval filters is justified.

Main Methods:

  • A review of a recent series of caval filter insertions was conducted.
  • Twenty-one filters were inserted in 20 patients over a 1-year period.

Main Results:

  • The operative mortality rate was 0%.
  • Satisfactory filter placement was achieved in 90% of patients.
  • No recurrent emboli or vena cava thrombosis were documented.

Conclusions:

  • Vena cava filter use is justified as prophylaxis for patients at high risk of pulmonary embolism.
  • This is particularly relevant in clinical settings where heparin therapy is inappropriate.
