The only TWO widely accepted and validated indications for IVC filter placement:
|
Absolute contraindication to anticoagulation; Failure of anticoagulation with acute proximal DVT
|
|
|
situations where IVC filter placement is controversial:
|
compromised pulmonary vascular bed that another event would be poorly tolerated. Example: acute hemodynamically massive PE and chronic thromboembolic pulmonary hypertension; Proximal DVT with poor cardiac reserve; DVT with high risk of bleeding

|
Indications for placement of a suprarenal filter
|
renal vein thrombosis, IVC thrombus extending above renal veins, and thrombus in infrarenal IVC without sufficient room above thrombus and below renal veins.
|
|
|
usual position of IVC filters
|
Infrarenally
|
|
|
IVC filters are placed with what type of guidance (2)
|
fluoroscopy or US guidance. (Fluoroscopy requires transport to radiology and uses IV contrast

|
IVC filter added to standard anticoagulation results in reduced risk of subsequent PE; but increases incidence of
|
DVT. (does not increase overall risk of DVT, postthrombotic syndrome, or mortality.

|
|
Complications of IVC filters
|
Local (eg, hematome); DVT at site of insertion; Filter migration; Filter erosion through IVC wall; Filter embolization; IVC thrombosis/obstruction

|
|
Whether concomitant anticoagulant therapy should be utilized following filter placement
|
Unknown

|
|
Acute insertion site thrombosis has been reported in up to 40 percent of patients undergoing filter placement and appears to be more common when

using both a femoral approach and a large introducer
