Question: Does a design modification to minimize tilting of an inferior vena cava filter deliver a clinical benefit?
Answer: Overall, tilt angle at insertion did not differ between the modified and standard filters, although more modified filters displayed self-centering. There was no difference between the groups in retrieval failure due to excess tilting. Despite its greater tendency to self-center, we did not recognize a measurable clinical advantage of the modified filter.

no
