Optional vena cava filter use in the elderly population

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Geriatric Medicine

Background:

• Inferior vena cava (IVC) filters are used to prevent pulmonary embolism (PE).
• The use and retrieval rates of optional IVC filters in elderly patients require further investigation.

Purpose of the Study:

• To evaluate the utility, safety, and efficacy of optional IVC filters in patients aged 65 years and older.
• To compare outcomes between optional and permanent IVC filters in this age group.

Main Methods:

• Retrospective review of patients aged 65+ who received optional or permanent IVC filters.
• Comparison of technical success, recurrent PE, thrombotic complications, and filter retrieval rates.
• Analysis of retrieval rates in optional filter recipients compared to a general cohort.

Main Results:

• Technical success rates for optional and permanent filters were comparable (98.1% vs. 99.8%).
• Pulmonary embolism rates were low in both groups (0% optional vs. 1.4% permanent).
• Deep vein thrombosis rates were higher in the optional filter group (12% vs. 4.5%), but not statistically significant (P = .06).
• Filter retrieval was attempted in 55.6% of optional filter recipients, similar to younger patients.

Conclusions:

• Optional IVC filters demonstrate safety and efficacy in patients aged 65 years and older.
• Age alone is not a reliable indicator for predicting the opportunity for filter removal.
• Achieving high retrieval rates comparable to younger populations is feasible with appropriate patient selection and diligent follow-up.
