Comparative StudySimulation in training: one-year experience using an efficiency index to assess interventional radiology fellow training status.
To compare objective fellow and expert efficiency indices for an interventional radiology renal artery stenosis skill set with the use of a high-fidelity simulator. ⋯ Objective efficiency indices for simulated procedures can demonstrate scores directly comparable to the level of clinical experience.

Clinical TrialSafety and efficacy of CT-guided percutaneous cryoablation for renal cell carcinoma.
Image-guided percutaneous cryoablation is a treatment alternative for selected patients with renal cell carcinoma (RCC). The objective of the present study was to present the safety and efficacy of percutaneous cryoablation. ⋯ CT-guided percutaneous cryoablation resulted in complete response for lesions as large as 4 cm. It may also be a viable alternative for nonsurgical candidates with lesions as large as 7 cm. It has a high efficacy rate, and its modest complications are not only comparable to those of other treatment modalities, but also appear to be reversible.

Clinical TrialAcute lower gastrointestinal hemorrhage: minimally invasive management with microcatheter embolization.
To evaluate the efficacy of superselective embolization therapy in the management of acute lower gastrointestinal (LGI) hemorrhage, including any bleeding distal to the ligament of Treitz. ⋯ Superselective embolization may be used for effective, minimally invasive control of acute LGI bleeding.

Factors associated with failed retrieval of the Günther Tulip inferior vena cava filter.
To identify potential factors associated with failed retrieval of the Günther Tulip inferior vena cava (IVC) filter. ⋯ Prolonged dwell time and increasing patient age are associated with failed filter retrieval. However, even filters in place for extended periods can be safely removed.
