IVC filters are small devices that are put inside the Inferior Vena Cava (IVC) for barricading the path of migrant embolism, which is wandering blood clots that have come off from the site of their formation in the lower Deep Veins in the legs.
The IVC is the primary vein taking blood from the parts of the body below the mid-section to the right atrium of the heart. These veins are wide in width and therefore do not normally block the flow of blood in case an unwanted piece of solid material is flowing through it to the heart. Owing to this, the progress of blood clots and other types of drifting debris is not checked during the length of the IVC Filter.To know more on ivc filters you may browse http://www.bardfilterlawsuitcenter.com/bard-ivc-filter-lawsuits.asp.
Once the bits reach the lungs, the heart, or the brain in severe cases, they may cause pulmonary embolism (an instance of debris blocking the pulmonary artery), ischemia (blood supply cut off from tissues) and infarction (death of tissues due to privation). Inability to move, heart attacks, and stroke are common terms for the positions described above.
IVC filters are seldom the first plan of action for the inhibition of Pulmonary Embolism when a thrombus is known to have developed in the lower legs. Normally, anticoagulants are given to cause thinning of the blood and dissolution of the clot. However, in case these types of medicines cannot be used due to some complex requirements identified in the patient, then IVC filters become an option for further action.
