ABSTRACT
PURPOSE:
To evaluate the effectiveness of percutaneous placement of a Greenfield titanium filter in the inferior vena cava (IVC) for the prevention of pulmonary embolism (PE) in patients with deep vein thrombosis (DVT). MATERIALS ANDMETHODS:
Twelve patients with DVT underwent percutaneous Greenfield titanium filter placement. The indications included recurrent pulmonary embolism or failed anticoagulation therapy in six patients, extensive PE in three, and prophylaxis for high risk of PE in the remaining three. In all cases the filter was positioned after confirming the anatomy, patency, and presence of thrombosis of the IVC and renal veins by inferior vena cavography. Long-term follow-up study involved clinical evaluation, plain radiography, Doppler ultrasonography and CT scanning.RESULT:
Filter placement [infrarenal in ten patients (83%) and suprarenal in two (17%)] was technically successful in all cases (100%). The venous approach involved the right femoral vein in eight patients (67%) and the right internal jugular vein in four (33%). Complications included overlapping of the filter legs in three patients (25%), and misplacement in one (8%). After filter placement, no further PE developed. In all of five patients followed up for two years, the IVC maintained patency without evidence of caval perforation or occlusion.CONCLUSION:
In patients with DVT, percutaneous placement of a Greenfield titanium filter is a safe and effective method for the prevention of PE.
