Answer

When using ligation for caval interruption, the proper level must be chosen. Ligation effects a permanent, complete occlusion of the IVC, but the risk of recurrent PE is not zero.

Filters are relatively noninvasive, allow central flow, and may be placed at several different anatomic levels as indicated by the clinical situation. However, thrombosis may occur at the insertion site or at the site of the filter itself. There are numerous proprietary configurations of filters available, and the technology is constantly changing; therefore, data from older studies may not extrapolate to current devices.
