| Summary: | Purpose To investigate the factors contributing to inferior vena cava (IVC) filter removal failure
by comparing successful and failed cases using advanced techniques.
Materials and Methods IVC filter removal was attempted in 331 patients. Of the 29 patients
in whom IVC filter removal failed using a simple technique, the IVC filter was successfully
removed using an advanced technique in 18 patients and failure was noted in 11 patients.
Age, sex, filter type, indwelling period, IVC diameter, tilting angle between the IVC and the
filter, IVC wall penetration of the filter strut, and whether the filter was embedded or endothelialized
within the IVC wall were compared in each group.
Results Overall, there were 13 men (72%) in the success group and 3 men (27%) in the failure
group; more women were present in the failure group (p = 0.027). Unlike in the success
group, hook embedment (9/11, 82%) or IVC filter endothelialization (2/11, 18%) within the
wall of the IVC were observed in the failure group using two-dimensional venography.
Conclusion When using advanced techniques for IVC filter removal, females are at a higher
risk of failure compared to males. Hook embedment and IVC filter endothelialization within
the IVC wall, rather than penetration of the IVC wall, are crucial factors in failure of IVC filter
removal using advanced techniques. |
