Photothermal ablation with the excimer laser sheath technique for embedded inferior vena cava filter removal: initial results from a prospective study.
To evaluate the safety and effectiveness of the excimer laser sheath technique for removing embedded inferior vena cava (IVC) filters. ⋯ The laser-assisted sheath technique appears to be a safe and effective tool for retrieving embedded IVC filters, including permanent types, with implantation ranging from months to > 18 years.

Comparative StudyOptional vena cava filter use in the elderly population.
To review utility, safety, and efficacy of optional inferior vena cava (IVC) filters in patients 65 years or older at a single institution over a 6-year period. ⋯ Optional filters are safe and effective in patients aged 65 years or older. Age alone is a poor predictor of a clinical opportunity to remove a filter. With appropriate patient selection and aggressive follow-up, retrieval rates comparable with those in younger populations can be achieved.

Retrievability and device-related complications of the G2 filter: a retrospective study of 139 filter retrievals.
To evaluate the retrievability and safety of the G2 filter. ⋯ The majority of G2 filters can be removed without difficulty. The most common factor affecting retrieval was severe tilting. The indwelling time had no impact on retrieval. G2 filter-related complications were frequent but most, including fractures, were clinically insignificant.

Laparoscopic demonstration of vena cava wall penetration by inferior vena cava filters in an ovine model.
To verify the penetration of struts and hooks of two inferior vena cava (IVC) filters (Günther tulip retrievable filter [GTF] and Celect filter) through the vena cava wall and to assess local or systemic complications resulting from this penetration. ⋯ GTFs and Celect filters can produce a real penetration 1 month after implantation. This penetration did not lead to any complications in the IVC or surrounding tissues and did not compromise the subject's health in any of the studied cases.
