What Are The Most Common Risks Associated With IVC Filters?

Each product’s directions for use and the risks involved would have to be examined, but generally speaking, there would be a risk of the device perforating the inferior vena cava which would cause some internal bleeding. There would also be a risk for the device to not stay where it was supposed to be and that it could actually migrate with the blood flow and end up in the heart, which would be a big problem. There is a risk the device could tilt to such a degree that it was not really doing its job and it was not catching the clot so it was basically useless and therefore there was really no need for it. In this case it would not be doing anything but it would still be at risk for migrating. We have seen quite a few cases where an arm or a leg of the device had fractured off and then that could either perforate another organ system or actually migrate into the heart, which would obviously be bad news.

When Did Reports About Complications And Dangers Of IVC Filters Begin To Surface?

The FDA has recently become more involved. The initial FDA safety communication was in the Fall of 2010, and then more recently in May of 2014, the FDA came out with a little bit stronger safety communication essentially saying they had received a rash of adverse events and that retrievable filters should really be removed once the patient no longer needed them and the patient would need to be monitored regularly. A publication suggests that if someone needed to get the filter out if it was no longer needed, then they should do so between 29 and 54 days whereas we just do not see that happen. We see cases involving retrievable filters that have been there for 10 years and were causing problems that nobody was able to figure out were actually related to the presence of the filter. Symptoms like shortness of breath, pain in the abdomen, pain in the low back, internal bleeding or things of that nature would basically be going on undiagnosed until finally some imaging was done so they were able to figure out the IVC device was in five or six pieces and the pieces had travelled all over the body.

What Are The Most Serious IVC Filter Complications In The Cases That You Handle?

The most serious complication is death, because there would be nothing more serious than death. One particular filter, Bard’s recovery filter, has caused a number of deaths due to a fracture or migration of the entire device into the heart, which would cause an embolization. This would basically cause the problem from there, because it would either cause a bleed out or a cardiac issue resulting a death. This issue is not as rare as the manufacturers have indicated, although we would more typically see perforation of the vena cava where the device was essentially moored and could not be removed despite the fact that the patient might not need it anymore or was likely to not need it anymore, or there was a fracture of a few of the struts or legs or arms and then those pieces ending up in another organ system or in the heart, which would be a problem.
