Abstract

OBJECTIVE: The objective of this study was to determine the demographics and subjective rationale for failure to present for retrieval of patients who had an inferior vena cava (IVC) filter placed.

METHODS: Between January 1, 2010, and September 12, 2017, there were 242 patients who had retrievable IVC filters placed. Demographics and indications for filter placement were retrospectively analyzed. All patients who failed to have the filter retrieved were contacted by Institutional Review Board-approved telephone survey to delineate the reason that the filter was not removed.

RESULTS: Of 242 patients with IVC filters placed, 53 (22%) patients presented for filter retrieval at Abington-Jefferson Health. Patients who presented for filter retrieval were statistically younger (46 years vs 65 years; P < .001). The most common indication for filter placement in both groups was preoperative placement for bariatric surgery, but this percentage was higher in the group that presented for filter retrieval (70% [37/53] in the retrieved group vs 47% [88/189] in the nonretrieved group; P = .018). After telephone survey that reached 146 patients, it was determined that 46 (32%) patients who did not return for filter retrieval were told to keep the filter in place secondary to comorbidities, 28 (19%) did not remember being instructed to follow up for retrieval, and 18 (12%) did not want another procedure. Twenty-four patients were deceased at the time of telephone survey (16%). The remainder of the patients had the filter removed at an outside institution or gave another reason.

CONCLUSIONS: Our study documented a disappointingly low rate of filter retrieval. Patients with IVC filters who failed to present for retrieval were more likely to be older and frequently did not understand the complications of leaving a filter in place and the need to have the filter retrieved. Patient education should be increased to better capture patients with IVC filters and to improve retrieval rates, but our study showed that a significant percentage of patients do not have filters retrieved because of comorbidities or they do not want another procedure.
