Inferior Vena Cava Filter Placement - An Improved and Effective Treatment of Pulmonary Embolus  

The Inferior Vena Cava Filter Placement or IVC filter is a medical device that can be placed in the body to check pulmonary embolus (PE) - blockage of the main artery of the lung). Physicians use this device to remove the blood clots in a patient’s vein. These blood clots pose threat of breaking free and becoming lodge in a person’s lung, which may be fatal. In the treatment process, the filler is placed in the inferior vena cava, which is a large blood vessel located in a person’s abdomen to bring blood to the lung. The purpose of the IVC filter is to catch any clots that break free flow of the blood from reaching the lung.

This diagnosis method is used in case of contraindication to anticoagulation, failure of anticoagulation in patients who have a venous thromboembolic disease or in prophylactic with a high risk of blockage in the main artery of the lung. The blockages occur due to embolization of air, fat or amniotic fluid in small proportion, and such obstructions lead to the symptoms of pulmonary embolus. The risk of PE is increased in several situations including cancer and prolonged bed rest. Its symptoms include difficulty breathing, palpitations, and chest pain on inspiration. Sometimes, in the severe cases of PE can lead to abnormally low blood pressure, collapse, and sudden death.

To diagnose PE, an inferior vena cava filter can be implanted to prevent new emboli from entering the pulmonary artery and combining with an existing blockage. Initially, the IVC filters were placed surgically, but now it can be placed via groin through a thin tube or catheter. The modern filters are much thinner catheters. Its insertion largely depends on the amount and location of blood clot within the venous system. Under the Inferior Vena Cava Filter Placement and Removal process, it is pushed through the catheter and placed into the desired location. Probably ultrasound-guided placement is preferred in the setting of contrast allergy, renal insufficiency. In this way, the removal process becomes easier as well as effective.
