Types of IVC Filters
An inferior vena cava (IVC) filter is a small device that can stop blood clots from going up into the lungs. The inferior vena cava is a large vein in the middle of your body. The device is put in during a short surgery. Veins are the blood vessels that bring oxygen . An IVC filter is a device that is placed in the Inferior Vena Cava to stop blood clots. Lately, there have been many lawsuits concerning the safety of these devices, and IVC filter lawyers at Cochran, Kroll & Associates, P.C. have been involved with these cases as the understanding of the science catches up with the patients’ claims.
Inferior vena cava IVC filters fall into two basic categories—permanent IVC filters, which are designed to remain in place indefinitely and retrievable IVC filters, which can be removed as soon as it medically advisable. Retrievable filters in the U.

Retrievable or optional IVC filters are sometimes referred to as temporary filters, even though they are FDA cleared for permanent placement. Though there is one IVC filter that is specifically designed to be implanted only on a temporary basis and cannot be used permanently. It is the B. According to the manufacturer, this device is designed to provide effective filtration for up to three months.
Fortunately the leg was embedded in the inferior vena cava wall and did not migrate. All types of IVC filters are cleared by the Food and Drug Administration as a treatment for recurrent pulmonary embolism under the following conditions:. Use of these devices as a preventative measure in patients without a history of pulmonary embolism or where anticoagulant therapy can be used successfully, does not currently have FDA approval. The term off-label is most often applied to medications, but may also apply to use of a medical device under conditions other than those for which the device has received FDA clearance.
Off-label use of IVC filters is common and is believed to represent more than half of all filters implanted in the United States. However, such use may be problematic. Inthe FDA warned that filter complications may be related to how long a filter has been implanted. The study is available on the FDA website. The U. Monsanto Company.

Inferior vena cava filters vary both in the size of the veins in which they can be implanted and in the materials of which they are made. One of the main IVC filter differences is related to the diameter of the vena cava for which they can how to make the best french toast batter used.
The Cook Celect filter is designed for use in vena cavas with diameters less than 30 mm and more than 15 mm. Most types of IVC filters are made of nonferromagnetic materials and are not affected by magnetic fields. This is important since it permits the use of magnetic resonance imaging MRI in patients who have been implanted with such filters. Some types of IVC filters, however, are made of weakly ferromagnetic materials. These filters are classified as MR Conditional.
In general, IVC filter complications appear to be much more common with retrievable filters than with permanent filters. Patients with retrievable filters had significantly more complications overall than those with permanent filters. Device related complications vena cava perforation, filter migration and filter fracture were significantly more common with retrievable filters compared to permanent filters. The authors expressed the view that retrievable filters may have sacrificed long-term design integrity for the sake how to increase resolution of photos ease of retrievability.
Tina R. Desai, MD, et al. Both of these IVC filters have been associated with high rates of what video format does dsi support of the inferior vena cava by the filter legs. This not only damages the IVC, but can damage organs outside the IVC, including the aorta, intestines, kidneys, pancreas and spinal column.
Filter fracture, tilt and migration were also seen in the Cook filters. The Northwestern University study mentioned above investigated six different Bard IVC filters as well as the Cook filters and several other brands.
Filter fracture what size is e fit shoes limb embolization the movement of a fractured filter leg through the IVC to another location, such as the heart or lung were both higher for the Bard filters than any of the other filters investigated.
In Maythe journal Thrombosis Research published a study of patients who experienced a major trauma 71 were involved in motor vehicle accidents and were treated with an Optease IVC filter. Removal of the filter was unsuccessful in 13 patients.
Filters made by seven different IVC filter manufacturers will be tested and subjects will be enrolled for each filter. The seven filters to how to permanently delete facebook tested and their manufacturers are as follows:. The study will investigate the major IVC filter complications that have been associated with these medical devices.
These include:. The filter manufacturers are funding the research and collaborating with New England Research Institutes Inc. NERI in carrying out the study.

G2: The G2 was cleared as a permanent filter inbut it can be retrieved. Celect: The Celect was cleared for permanent use in and retrievable use in The Optease was approved as a permanent filter in and as a retrievable filter in When anticoagulant therapy has been unsuccessful.
Chronic, recurrent pulmonary embolism when anticoagulant therapy has failed or is could be harmful. Pilliod et al. Monsanto Co. Hardeman v. Differences in IVC Filters Inferior vena cava filters vary both in the size of the veins in which they can be implanted and in the materials of which they are made. Vena Cava Diameter One of the main IVC filter differences is related to the diameter of the vena cava for which they can be used. Materials Most types of IVC filters are made of nonferromagnetic materials and are not affected by magnetic fields.
Bard Peripheral Vascular, Inc. These include: Penetration of filter legs through the inferior vena cava wall resulting in: hemorrhage or hematoma touching or perforation of other organs a decision to remove the filter Movement of the filter or its parts to a distant site e. Occlusion blocking of the inferior vena cava. This can be caused by the filter capturing blood clots or the tendency of the filter to promote the formation of blood clots. Deep vein thrombosis that occurred after the implantation of the filter.

Permanent IVC Filters: Manufacturer and Date of FDA Clearance
The Evidence for IVC Filters Although IVC filters are an established therapy for DVT and PE, the evidence base for their benefits is thin. An IVC filter is a small metal device implanted in the inferior vena cava, the large vein that returns blood back to the heart from the lower body. It is placed in the vein to prevent dangerous blood clots from traveling to the lungs. There are two categories of IVC filters. FDA Approved Uses for IVC Filters All types of IVC filters are cleared by the Food and Drug Administration as a treatment for recurrent pulmonary embolism under the following conditions: When the patient’s condition is such that treatment with anticoagulants would cause harm. When anticoagulant therapy has been unsuccessful.
The primary treatment for blood clots in the legs deep vein thrombosis or DVT is blood thinners anticoagulants. However, some patients may not be able to receive blood thinners, either temporarily or permanently. In those patients, an inferior vena cava IVC filter is the next best option. An IVC filter is a small metal device implanted in the inferior vena cava, the large vein that returns blood back to the heart from the lower body. It is placed in the vein to prevent dangerous blood clots from traveling to the lungs.
There are two categories of IVC filters:. The type of filter implanted depends on a variety of factors such as the patient's ability to take blood thinners and the length of time the risk for blood clots is present. Inside the vein, the IVC filter works by allowing blood to flow around a trapped blood clot until the body's natural blood thinner anticoagulants break it down.
Without the IVC filter in place, a blood clot traveling to the lung could cause a blockage of the pulmonary artery. This is known as a pulmonary embolism PE , a life-threatening condition. IVC filters may need to be removed because they can increase risks of new blood clot formation in the legs and abdomen. Removal is also recommended when the filter is no longer needed, according to the United States Food and Drug Administration.
It is recommended that a removable filter be removed when the risk of a blood clot traveling to the lungs has passed, or if a patient can take blood thinners. The following procedures are used to remove a previously implanted IVC filter.
Procedures are performed on an outpatient basis under moderate sedation or limited use of general anesthesia, with brief post-procedure observation and return to normal activities the next day. A special device called a snare is inserted into the jugular vein, the large vein in the neck. Most removable IVC filters have a small hook at one end. Using fluoroscopy X-ray guidance the snare is used to latch onto the small hook, and once attached, to withdraw the filter.
The procedure is usually done with moderate sedation and local anesthesia numbing medicine , though it can also be done under general anesthesia.
If this standard removal procedure is unsuccessful, an advanced complex filter removal procedure developed by Penn Interventional Radiology, called the "jaws of life" technique, can be used. Forceps retrieval is the preferred technique for complex IVC filter removal worldwide.
In this procedure, long forceps instead of a snare are used to gently tease the filter from the wall of the vein and remove it. This technique is very effective even when other complex filter removal techniques have been attempted and failed.
If the filter in place is one that is retrievable, you may be a candidate for removal. If you are not sure about the filter type, an office consultation with our Penn IR specialists can help to determine what treatment may be right for you. Request a consultation now. The risks for complex filter removal are slightly higher than those for routine removal. However, based on over 10 years of experience and performance of over complex removal procedures here at Penn IR, the risks are still very low.
Most routine medications are safe to continue taking, but there are a few exceptions. Blood thinners may or may not be suspended during the procedure depending upon the expected complexity of the removal. Please inform your physician of all routine medications you are taking to determine whether they are safe to continue. During your office visit, you will be instructed regarding which medications to continue taking. Access myPennMedicine For Patients and Visitors.
