AVF Journal Club: IVC Filter Retrieval Rates and Technique

Wide Variability in Filter Retrieval Rates Nationwide

Across 12,197 patients and 158 facilities, mean IVC filter retrieval rate was 23.2 percent, ranging from under 1 to 100 percent, with a median 74 day interval and only 43 percent retrieved within the 90 day window, with no academic versus non-academic difference.

Structured Tracking Programs Improve Accountability

One program, automatically scheduling a three month visit with mailed letters and a database managed by a physician assistant, achieved 98.5 percent filter accountability since 2012, while a broader referral system directly scheduling retrievals reached the mid-40s percent.

Denali, Tulip, and Option: Retrieval Success Compared

Among 189 patients, overall retrieval success was 96 percent, but Option filters failed more often due to tilt and embedded struts, needing advanced techniques in 21 percent of cases versus 2 percent for Denali, which also had shorter fluoroscopy and sedation times.

Clinical Pearls: Technique and Permanent Filter Decisions

Faculty described forceps retrieval focused on the filter tip, distinguished benign tine penetration from symptomatic perforation needing removal, and emphasized declaring truly permanent filters while flagging indwelling filters in the record to prompt follow up.
