Inferior Vena Cava Filter Removal after 317-day Implantation

The Günther-Tulip Retrievable IVC Filter

“…The longest period from implantation to retrieval reported to date is 317 days. 34 In the present study, there was no recurrence of symptomatic DVT in the patients with permanent implantation of a GTF. The PREPIC study found that symptomatic DVT occurred in 36% of patients with a permanent filter at 8-year follow-up, 33 but in that study, only 35% of patients were on anticoagulation therapy.…”

Retrieval of Gunther Tulip Vena Cava Filter with Thrombosed Hook and a Leg Incorporated into the Vena Cava Wall

“…6) According to initial clinical reports of retrieval of GTFs, 3) the maximal period of implantation before successful retrieval was recommended to be no longer than 10-14 days. This period was based on results of animal investigation that showed filter legs were incorporated into the contacted IVC wall due to the reaction of IVC Takuji Some recently published clinical studies, 6,9,10) however, reported successful retrieval of GTF after a longer period of implantation. Millward et al 6) noted that the maximal period of implantation before successful retrieval was 25 days, Terhaar et al 9) reported a period of 126 days, and more recently Binkert et al 10) reported a period of 317 days.…”

However, although retrieval has been successful beyond 10-14 days, the incidence of filter fixation to the caval wall increases after 16 days by animal investigation.…”

“…Both of these events might have been caused by the relatively long implantation period, although the period of implantation was within the period previously reported in which GTF was successfully retrieved. 9,10) To overcome the first problem, we used the snare-over-guide wire method after which the cephalad site of the filter was introduced into sheath. A : Roentgenogram shows the first half of the snare-over guide wire technique.…”

Advanced Techniques for Removal of Retrievable Inferior Vena Cava Filters

“…Günther Tulip filters have been similarly retrieved at prolonged intervals, e.g. 317 and 475 days [62,63] but with a decreasing success rate as dwell times increase [64]. Recently, Lynch reported removal of a filter at 3006 days after implant [65].…”
