What is a true statement regarding IVC filters?

IVC filters, or inferior vena cava filters, are devices used primarily to prevent pulmonary embolism by capturing blood clots that may dislodge from the lower extremities. While they serve a vital functional purpose in providing temporary protection against these complications, they do not treat or resolve deep vein thrombosis (DVT) itself, nor do they address the underlying causes of coagulation disorders that lead to DVT.

The primary role of IVC filters is to provide a mechanical barrier to prevent emboli from entering the pulmonary circulation, but they do not influence clot formation or dissolution directly. They are designed to be a supportive measure, often used in patients for whom anticoagulant therapy is not suitable. Thus, the statement that IVC filters do not address the cause of deep vein thrombosis or coagulation accurately reflects their role in clinical practice.
