There were 42 men and 58 women (mean age, 46 years; limits, 18\u201376 years). Retrieval indications included filter-related acute inferior vena cava thrombosis, chronic inferior vena cava occlusion, and pain from retroperitoneal or bowel penetration. Filter retrieval was also performed to prevent risks from prolonged implantation and to potentially eliminate the need for lifelong anticoagulation. After standard methods failed, photothermal tissue ablation was attempted with a laser sheath powered by a 308-nm xenon chloride excimer laser. Applied forces were recorded with a digital tension meter before and during laser activation. Laser-assisted retrieval was successful in 98.0% (95% confidence interval [CI], 93.0%\u201399.8%) with mean implantation of 855 days (limits, 37\u20136663 days; >18 years). The following filter types were encountered in this study: G\u00fcnther-Tulip (n=34), Celect (n=12), Option (n=17), Optease (n=20, 1 failure), TrapEase (n=6, 1 failure), Simon-Nitinol (n=1), 12F Stainless Steel Greenfield (n=4), and Titanium Greenfield (n=6). The average force during failed standard retrievals was 7.2 versus 4.6 pounds during laser-assisted retrievals (\n P<\/jats:italic>\n <0.0001). The major complication rate was 3.0% (95% CI, 0.6%\u20138.5%), the minor complication rate was 7.0% (95% CI, 0.3%\u201313.9%), and there were 4 adverse events (2 coagulopathic hemorrhages, 1 renal infarction, and 1 cholecystitis; 4.0%; 95% CI, 1.1%\u20139.9%) at mean follow-up of 500 days (limits, 84\u20131079 days). Scar tissue ablation was histologically confirmed in 96.0% (95% CI, 89.9%\u201398.9%). Successful retrieval allowed cessation of anticoagulation in 30 of 30 (100%) patients and alleviated morbidity in 23 of 24 patients (96%).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions\u2014<\/jats:title>\n Excimer laser\u2013assisted removal is effective in removing embedded inferior vena cava filters refractory to standard retrieval and high force. This method can be safely used to prevent and alleviate filter-related morbidity.<\/jats:p>\n <\/jats:sec>\n \n Clinical Trial Registration\u2014<\/jats:title>\n \n URL:\n http:\/\/www.clinicaltrials.gov<\/jats:ext-link>\n .
