Multicenter Study Clinical TrialThe Jonas study: evaluation of the retrievability of the Cordis OptEase inferior vena cava filter.
To evaluate the success, safety, and efficacy of the retrieval of the OptEase Permanent/Retrievable Vena Cava Filter (Cordis, Warren, NJ), when implanted for temporary protection against venous thromboembolism. ⋯ The OptEase permanent/retrievable vena cava filter can be safely and successfully retrieved up to 14 days in patients who no longer require inferior vena cava filter protection against pulmonary embolism.

Randomized Controlled TrialIntraarticular hyaluronic acid versus glucocorticoid injections for nonradicular pain in the lumbar spine.
To investigate the efficacy and safety of intraarticular sodium hyaluronate (SH) compared with intraarticular glucocorticoids (triamcinolone acetonide; TA) in the treatment of chronic nonradicular lumbar pain. ⋯ Intraarticular SH is a very promising new option for the treatment of patients with chronic nonradicular lumbar symptoms.

Bench-top evaluation of air flow through a valved peelable introducer sheath.
Air embolism is a rare but potentially fatal complication that may occur during the insertion of a central venous catheter. A valved peelable introducer sheath was developed to reduce the likelihood of an air embolus. This study was performed to determine the rate of air flow through this valved introducer sheath under different conditions that may be encountered in a clinical setting. ⋯ This bench-top study revealed that a massive amount of air flowed through the open 16-F introducer sheath when it was subjected to a vacuum of -5 mm Hg, a situation that may occur under normal physiologic conditions. The rate of air flow could be decreased by aggressively pinching the sheath but the rate of air flow was still substantial. This study demonstrated that the addition of a sophisticated valve mechanism can essentially eliminate air flow through a peelable introducer sheath.

Multicenter StudyAttitudes of and influences on residents in English Canadian radiology programs regarding interventional radiology: results of a national survey by the Canadian Interventional Radiology Association (CIRA).
There has been a North American trend toward reduced application to the subspecialty of Interventional Radiology (IR). Out of fear of a looming manpower shortage, this survey was conducted to better understand awareness and attitudes toward IR by radiology residents-in-training. ⋯ A number of issues were identified as factors which prevented residents with an interest in IR from applying to IR fellowships. These must be addressed to increase IR recruitment rates of radiology residents.

Comparative StudyRadiation exposure to operators during vertebroplasty.
To measure the radiation received by physicians during percutaneous vertebroplasty with use of two types of injection devices with the interventional equipment guided by computed tomography (CT) and an angiographic/CT system. ⋯ Radiation dose was relatively high for operators performing percutaneous vertebroplasty. The bone cement injector was useful in reducing the level of radiation exposure to operators during vertebroplasty.
