Comparative StudyIndications for inferior vena cava filter placement: do physicians comply with guidelines?
Inferior vena cava (IVC) filter placement has increased significantly over the past few decades, but indications for filter placement vary widely depending on which professional society recommendations are followed, and it is uncertain how compliant physicians are in adhering to guidelines. This study assessed documented indications for IVC filter placement and evaluated compliance with standards set by the American College of Chest Physicians (ACCP) and the Society of Interventional Radiology (SIR). ⋯ There is poor physician compliance with guidelines for IVC filter placement. Most filter indications meeting SIR guidelines are for patients classified as "falls risks," failures of anticoagulation, patients with limited cardiopulmonary reserve and patients non compliant with anticoagulation medications. This single-center study suggests a need for harmonization of current guidelines espoused by professional societies.

Radiofrequency wire for the recanalization of central vein occlusions that have failed conventional endovascular techniques.
To report the technique and acute technical results associated with the PowerWire Radiofrequency (RF) Guidewire used to recanalize central vein occlusions (CVOs) after the failure of conventional endovascular techniques. ⋯ The present results suggest that the RF wire technique is a safe and efficient alternative in the recanalization of symptomatic and chronic CVOs when conventional endovascular techniques have failed.

Endoluminal dilation technique to remove "stuck" tunneled hemodialysis catheters.
Most tunneled catheters can be easily removed after the retention cuff is dissected. Occasionally, these catheters can become resistant to removal even after application of potentially hazardous forceful traction. ⋯ The present report describes the successful extraction of five such "stuck" catheters by using a recently described technique of endoluminal dilation. The technique appears safe and straightforward and can be performed in any interventional suite while allowing preservation of venous access.
