Purpose
To compare the retrieval and long-term complications rates of Inferior Vena Cava Filter (IVCF) according to caval filtration indications.
Materials & Methods
In this IRB-approved retrospective review, patients who underwent IVCF placement between January 2011 and December 2014 were selected. The following data was collected from IR clinic: patients' demographics, primary diagnosis, retrieval rates and IVCF complications. Patients were classified according to their indication for IVCF (SIR guidelines) into three groups: absolute, relative or prophylactic. Results are given in mean± SD. Statistical analysis was performed with logistic regression and Kruskal-Wallis tests with significance considered at p<.05.
Results
A total of 376 patients (54.8% male; 45.2% female; age 59.5±17.5 years) were included in the analysis, and classified into three groups: 60.4% (n=227) absolute, 10.6% (n=40) relative, and 29% (n=109) prophylactic. Dwell times were 205.5, 184.5, and 223 days in the absolute, relative and prophylactic groups, respectively, with no statistical significant differences found. Overall retrieval rate was 42% (n=157), with statistically significant lower (p<0.001) rates in the absolute group (31.3%,n=71), as compared to relative (57.5%,n=23), and prophylactic (67%,n=63) groups. Overall complication rate was 9.6% (n=36) with no differences noted in the absolute (5.6%,n=21), relative (1%,n=4) and prophylactic (2.7%,n=10) groups. Predictors for non-retrieval included: age (OR=1.05, 95%CI:1.03-1.1), malignancy (OR=1.9, 95%CI:1.1-3.3) and presence of venous thromboembolism (VTE) (OR=3.1, 95%CI:1.7-5.6).
Conclusions
Complication rates and dwell times do not vary significantly among groups, but retrieval rates were lower in the absolute group. Predictors for non-retrieval included: age, malignancy and presence of VTE. Further analysis with larger cohort is needed to determine which factors contribute to retrieval rate and IVCF complications.
