Excimer Laser Assisted IVC Filter Retrieval

Northwestern University535 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

Evaluate any adverse events related to laser assisted 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.

Time frame: up to 1 year after Laser Assited IVC filter removal

Effectiveness of Laser Assisted 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.

Time frame: At time of IVC filter removal
