Brief summary
This is a prospective chart review to follow our laser-assisted IVC filter retrieval patients. We intend to validate existing literature and scientific findings by publishing our own clinical experience in difficult IVC filter retrievals.
Detailed description
At Northwestern Memorial Hospital in Chicago, IL USA, IVC filters are successfully removed \>95%. Technical failures, although rare, are usually related to excessive endoluminal scarring at the point of IVC filter implantation. Adjunctive (or advanced) removal techniques are often employed in difficult cases. The excimer laser sheath has been successfully used at Northwestern for patients who had failed all other retrieval techniques. Before a patient is to undergo an IVC filter removal using the Excimer Laser Sheath they will be consented to participate in the chart review study and become a part of a registry kept at Northwestern Memorial Hospital. The procedure itself is not being used as part of the study. Chart reviews will be completed and data collected on the procedure to remove the filter. Follow up after the procedure by phone call and chart review will be completed at least once, 1 week after the filter removal.
Interventions
The laser assisted IVC filter removal procedure itself is not part of this study. This is a prospective chart review for patients undergoing this procedure.

* Patients who refuse the use of the excimer laser device to attempt to remove their IVC filter.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate any adverse events related to laser assisted IVC filter removal | up to 1 year after Laser Assited IVC filter removal | The number and severity of adverse events will be recorded to evaluate safety. This will be conducted as a phone call to the patient 1 week after IVC filter removal and then as a chart review only. |
| Effectiveness of Laser Assisted IVC filter removal | At time of IVC filter removal | Success rate of removing IVC filters using the laser will be recorded. If a filter cannot be removed with the laser the reason for this failure will be recorded. |
