Inferior vena caval filter is deployed:<\/strong>
\na) Above the renal veins
\nb) At the renal veins
\nc) Below the renal veins
\nd) Below the hepatic veins
\nCorrect answer:\u00a0c) Below the renal veins<\/strong>
\nInferior vena caval (IVC) filter is usually deployed to prevent migration of venous thrombus from lower limb or pelvic veins to the right heart and the lung, with an aim to prevent pulmonary embolism. Both temporary retrievable and permanent IVC filters are available from different manufacturers. The filters have barbs or hooks to prevent migration within the IVC. The filters are usually deployed below the renal veins under fluoroscopic guidance.
\nFilters with delivery systems suitable for trans femoral, trans jugular and trans cephalic vein delivery are available.
\nRarely thrombus formation can occur above the filter and sometimes embolisation can still occur through large collaterals which can form once the filter is clogged by thrombi. IVC filters are considered in case of recurrent massive pulmonary embolism, especially when there is a contraindication to long term anticoagulation. Short term anticoagulation is needed after implantation of an IVC filter.
\nRare case of IVC filter inadvertently deployed in the aorta being successfully retrieved by simultaneous trans brachial and trans femoral approach has also been reported [1]. Another case of endovascular retrieval of IVC filter penetrating the aorta and causing abdominal pain has also been reported [2].
