A new study reveals a brand of IVC filter — a small, metal cage-like device used to prevent blood clots from entering the lungs — poses a significant risk of puncturing a major blood vessel.
The Cook Celect filter had a 43 percent rate of perforation versus the Option filter, which had a zero percent perforation rate. Study authors noted this was a “significantly higher rate.”
In the study published in June 2015 in the Journal of Vascular Interventional Radiology, researchers looked at the records of 99 people implanted with the Cook Celect IVC filter and 86 patients who received an Option filter sold by Rex Medical. After about two months, doctors retrieved the filters. While surgeons had slightly more difficulty retrieving Option filters from the vein, the difference in the rate of retrieval was negligible.
Researchers were more concerned with a potentially troublesome complication: vena cava perforation.
