In what condition would a Greenfield Filter typically be used?

A Greenfield Filter is specifically designed to prevent pulmonary emboli by capturing blood clots that may travel from the lower extremities to the lungs. It is primarily indicated for patients with deep vein thrombosis (DVT) who are at high risk for developing such clots. This intervention is critical in settings where patients cannot receive anticoagulant therapy, perhaps due to contraindications or complications.

The use of this filter significantly decreases the risk of life-threatening complications associated with DVT and pulmonary embolism. Thus, its application in DVT prevention aligns perfectly with its clinical purpose and function. Understanding this context highlights why a Greenfield Filter is a vital tool in managing patients at risk of thromboembolic events.
