Inferior Vena Cava Filter
An inferior vena cava (IVC) filter , is a vascular filter that is inserted through a small incision into the main vein in the abdomen. This vein in the abdomen is called the inferior vena cava. The filter prevents blood clots from breaking loose in leg veins and lodging in the lung. The IVC filter is typically implanted permanently in those patients with a high risk of pulmonary embolism.
