Purpose: To evaluate the mid- and long-term outcomes of inferior vena cava (IVC) filter insertion in patients with underlying deep vein thrombosis for prevention of pulmonary thromboembolism, based on a single center experience.
Materials and Methods: A total of 166 IVC filter insertion procedures in 160 patients, between February 2004 and December 2014, were retrospectively reviewed. Severity of deep vein thrombosis, indwelling time of the IVC filter, retrieval rate, and complication rate depending on the type of IVC filter were analyzed based on the patients' radiologic findings and medical records.
Results: IVC filter insertion procedures were successfully performed in all patients. Among the 99 attempts at filter retrieval, 91 trials succeeded (91.9%, 91/99) and 8 trials failed. Indwelling time of the IVC filter showed a positive correlation with failure of filter retrieval (p = 0.01). There was no procedure-related complication after all IVC filter insertion procedures. Eight delayed complications (5.0%, 8/160 patients with IVC filter insertion) were observed [caval thrombosis below the IVC filter (n = 7) and IVC penetration (n = 1)]. Gunther Tulip filter was associated with a significant incidence of complication (p = 0.036).
Conclusion: IVC filter insertion in patients with lower extremity deep vein thrombosis for prevention of pulmonary thromboembolism can be regarded as a safe treatment modality with an acceptable complication rate.
