Venous thromboembolic disease: the use of "optional" inferior vena cava filters.

Approximately 140,000 to 200,000 patients die as a result of pulmonary embolism in the United States each year. If the diagnosis is made and therapy initiated, the mortality rate drops to 8%. Vena cava filters play a role in the management of patients with thromboembolic disease.

Image-guided percutaneous radiofrequency ablation for osteoid osteomas.

The authors present a retrospective analysis of the technical and clinical successes, complications, and clinical follow-up of image-guided percutaneous radiofrequency (RF) ablation of osteoid osteomas. Nine patients with osteoid osteomas underwent image-guided localization of osteoid osteomas. Outpatient percutaneous therapy (13 procedures) was performed under general anesthesia after image-guided localization of the nidus.
