Improving inferior vena cava filter retrieval rates: impact of a dedicated inferior vena cava filter clinic.
To test the hypothesis that an inferior vena cava (IVC) filter clinic increases the retrieval rate of optional IVC filters. ⋯ The retrieval rate of optional IVC filters at this institution was significantly increased by the establishment of a dedicated IVC filter clinic. This retrieval increase is not related to a decrease in technical failures but more likely relates to more meticulous patient management and clinical follow-up.

Case ReportsThe excimer laser sheath technique for embedded inferior vena cava filter removal.
An inferior vena cava (IVC) filter became embedded within the IVC of a 45-year-old man after prolonged implantation. Because of incorporation of the filter legs within the caval endothelium, the filter was densely adherent and could not be sheathed using standard retrieval methods. In this patient, the authors performed percutaneous filter retrieval using an excimer laser sheath technique for circumferential ablation of dense fibrotic tissue between the filter and IVC. Endovascular laser ablation allowed facile separation of the filter from the IVC, without tearing of the tissues, and the filter was removed successfully without complication.

Randomized Controlled Trial Multicenter StudyTROPICS 1: a phase III, randomized, double-blind, placebo-controlled study of tenecteplase for restoration of function in dysfunctional central venous catheters.
To evaluate the efficacy and safety of the thrombolytic tenecteplase, a fibrin-specific recombinant tissue plasminogen activator, for restoring function to dysfunctional central venous catheters (CVCs). ⋯ Tenecteplase was efficacious for restoration of catheter function in these study patients with dysfunctional CVCs.
