IVC filters are used in people who have suffered or are likely to suffer from a pulmonary embolism. This usually occurs when a blood clot from the lower body makes its way into the lungs and heart, causing serious injury and in cases, death. The filter is placed into the inferior vena cava artery just below the kidneys and filters out blood clots before they can reach the heart of lungs. Recently, some brands of IVC filters have come under scrutiny for being unable to be removed once the danger of embolism has passed.
A recent study compared the ease of removal in three different IVC filter types. Dr. Eric T. Aaltonen, MD, MPH, conducted the study at NYU Langone Medical Center.
The reason for the study was because the facility had begun placing Denali IVC filters in patients. When the patients returned for filter retrieval, it was noticed that the Denali IVC filters had less tilt and were subsequently easier to remove than other similar filters. This led to a retrospective study on two other types of filters also placed at the same hospital. The ALN and Option filters placed were compared to the Denali filters.
The results of the study showed that the Option filters had more tilt and this resulted in more retrieval time when compared with the Denali filters. There was no significant difference in the rate of tilt with the ALN filters when compared to the Denali brand. The amount of tilt corresponds directly to the amount of equipment used and fluoroscopy time in retrievals.
Dr. Aalatonen also recommends that several factors be considered when choosing which brand of IVC filter is used. There are several on the market and the study only compared three of these. The factors that should be considered in the choice include appropriate indications, temporary versus permanent filtration, retrieval rates when filtration is no longer indicated, and the long-term safety of retrievable filters that are lost to follow-up.
Dr. Aalatonen stated that further research did need to be completed with larger retrieval groups and more filter brands.
