Interventional radiology simulation: prepare for a virtual revolution in training.
It is becoming increasingly difficult to learn interventional radiology (IR) skills because there are fewer "straightforward" invasive diagnostic imaging studies, a reduction in the time available for training, concerns about patient safety, and changing patient perceptions. Computer-based simulation has the potential to allow an operator to realistically perform a virtual procedure with feedback about performance and could remove at least some of the patient's role during the learning curve. To do this effectively requires a strategy for integrating simulator models into curricula and the development of standards for their validation.

Analysis of tip malposition and correction in peripherally inserted central catheters placed at bedside by a dedicated nursing team.
To analyze the patterns of postplacement tip malposition in peripherally inserted central catheters (PICCs) placed at bedside, and to describe results of bedside and imaging-guided correction of tip malposition. ⋯ Tip malposition is relatively frequent with bedside placement of PICCs. Preliminary data suggest that most malpositions can be corrected with bedside techniques. Spontaneous correction may occur but is relatively uncommon.

Analysis of simulated angiographic procedures. Part 2: extracting efficiency data from audio and video recordings.
To create and test methods of extracting efficiency data from recordings of simulated renal stent procedures. ⋯ Task analysis facilitated both protocol development and data analysis. Efficiency metrics were readily extracted from recordings of simulated procedures. Aggregating the metrics and dividing the procedure into segments revealed potential insights that could be easily overlooked because the simulator currently does not attempt to aggregate the metrics and only provides data derived from the entire procedure. The data indicate that analysis of simulated angiographic procedures will be a powerful method of assessing performance in interventional radiology.

Multicenter Study Clinical TrialRadiofrequency ablation for the treatment of unresectable lung metastases in patients with colorectal cancer: a multicenter study in Japan.
Results after lung radiofrequency (RF) ablation were retrospectively evaluated to determine whether lung RF ablation is an effective therapeutic option for the treatment of unresectable lung metastases from colorectal cancer. ⋯ Lung RF ablation is a safe and effective treatment in selected patients with unresectable lung metastases from colorectal cancer.

Use of the femoral vein as insertion site for tunneled hemodialysis catheters.
To determine the outcome of tunneled hemodialysis catheters inserted through the common femoral vein. ⋯ The femoral vein provides an alternative access site for insertion of tunneled hemodialysis catheters when conventional sites are not available. However, tunneled femoral hemodialysis catheters have low primary patency rates and significant complications. Catheter retraction is a unique and common problem.
