Summary
Percutaneous Greenfield filter placement in the inferior vena cava is highly successful for preventing pulmonary emboli. This minimally invasive technique should be the primary method for filter insertion.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Cardiology
Background:
- Pulmonary emboli pose a significant health risk.
- Inferior vena cava filters are used to prevent pulmonary emboli.
- Surgical cutdown and percutaneous insertion are methods for filter placement.
Purpose of the Study:
- To evaluate the efficacy and safety of percutaneous Greenfield filter placement.
- To compare percutaneous techniques with surgical cutdown for inferior vena cava filter insertion.
Main Methods:
- Retrospective review of 52 percutaneous Greenfield filter placements in 50 patients.
- Access via right femoral vein (37), right internal jugular vein (12), and left femoral vein (3).
- Inclusion of patients with altered coagulation factors.
Main Results:
- Successful filter placement in 51 of 52 procedures (98.1%).
- One major complication (hematoma requiring transfusion) in a patient with complex comorbidities.
- Femoral vein thrombosis occurred in 5% of patients undergoing femoral vein access.
Conclusions:
- Percutaneous Greenfield filter placement is a highly successful and safe method.
- This technique should be considered the primary approach for inferior vena cava filter placement.
- Minimally invasive filter insertion offers significant advantages over surgical methods.
