Summary

This trial will compare two methods for removing IVC filters, endovascular snare vs rigid forceps, to see if one offers an advantage in terms of success rates or procedure time.

Who is the study for?
Adults over 18 needing an IVC filter removal, specifically those with Cook Celect or Argon Medical Option Elite filters implanted for less than 6 months at UCMC. Excludes pregnant women, individuals with clotting disorders, prior filter procedures, central venous occlusion, or coagulopathy.
What is being tested?
The trial is comparing two common methods of IVC filter removal: using an endovascular snare device versus rigid forceps. The study aims to determine which method has higher success rates and shorter procedure times.
What are the potential side effects?
Potential side effects may include complications from the procedure such as bleeding due to vessel injury, infection risk at the access site, and possible migration of the blood clot during removal.

Trial Design

2Treatment groups
Active Control
Group I: SnareActive Control1 Intervention
Subjects randomized to this cohort will have their IVC filter removed using an endovascular snare (like a lasso) device that is designed to catch the hook of the filter and allow it to be captured.
Group II: ForcepsActive Control1 Intervention
Subjects randomized to this cohort will have their IVC filter removed using a rigid forceps device that will be used to engage the filter apex directly and allow for the filter to be capture/removed.
