Comparative StudyIn vitro study of guide wire entrapment in currently available inferior vena cava filters.
Guide wire entrapment by some older inferior vena cava (IVC) filters is known to occur, particularly with J-tipped wires. Three new IVC filters have recently been approved for use in the United States. An in vitro study was performed to compare the risk of engaging and entrapping guide wires in eight of the IVC filters currently available in the United States. ⋯ Among the IVC filters recently approved by the Food and Drug Administration, the TrapEase filter entrapped 3-mm and 1.5-mm J-tipped guide wires, whereas the Vena Tech LP and Günther Tulip filters did not. This study corroborates previously described wire entrapment by the stainless-steel Greenfield and Vena Tech LGM devices.

Percutaneous vertebroplasty has emerged as an effective technique for treatment of painful vertebral compression fractures (VCFs) caused by osteoporosis, malignancy, and some benign bone tumors. In selecting appropriate patients for vertebroplasty, it is important to distinguish the pain caused by VCF from other numerous causes of back pain. Careful adherence to clinical and imaging selection criteria is crucial to procedural success.

Thrombolysis of acute peripheral arterial and venous occlusions with tenecteplase and eptifibatide: a pilot study.
To prospectively assess the feasibility, risk profile, and effect on fibrinogen levels of combination tenecteplase (TNK) and eptifibatide in transcatheter thrombolysis for peripheral arterial and venous thromboocclusive disease. ⋯ In this initial study, the combination of TNK and eptifibatide was shown to be feasible for peripheral arterial and venous thrombolysis.

Percutaneous osteoplasty as a treatment for painful malignant bone lesions of the pelvis and femur.
The purposes of this report are to describe percutaneous osteoplasty as a highly effective minimally invasive procedure to treat painful malignant bone lesions of the pelvis, ilium, and femur and to discuss the relevant literature. Five patients with histologically proven metastases to the pelvis, ilium, or femur were treated by percutaneous injection of liquid bone cement as an attempt to control severe bone pain. ⋯ Whereas percutaneous osteoplasty of the spine (vertebroplasty) is well-described and widely accepted to treat pain caused by benign or malignant vertebral body diseases, osteoplasty of bones outside the spine is less known. The immediate good clinical results observed in our small patient group should encourage more widespread application of this palliative treatment.
