Comparative StudyThe effectiveness of locoregional therapies versus supportive care in maintaining survival within the Milan criteria in patients with hepatocellular carcinoma.
To compare survival after treatment with either locoregional therapy (LRT) or supportive care in patients with hepatocellular carcinoma (HCC) within the Milan criteria. ⋯ LRT is more effective than supportive care in prolonging survival within the Milan criteria in patients with HCC. The long-term survival in patients not undergoing transplant was significantly longer for patients who received LRT than for patients who were treated with supportive care.

Randomized Controlled Trial Comparative StudyProspective randomized comparative evaluation of proximal valve polyurethane and distal valve silicone peripherally inserted central catheters.
The objective of this study was to evaluate and compare the relative durability and complications between the proximal valve polyurethane and distal valve silicone peripherally inserted central catheters (PICCs). ⋯ Proximal valve polyurethane PICCs were more durable than distal valve silicone PICCs, which were associated with a higher incidence of phlebitis and infection, probably related to the materials of the catheters and the designs and placements of the catheter valves.

Multicenter Study Clinical TrialThe safety and effectiveness of the retrievable option inferior vena cava filter: a United States prospective multicenter clinical study.
To evaluate the safety and effectiveness of the retrievable Option inferior vena cava (IVC) filter in patients at risk for pulmonary embolism (PE). ⋯ Placement and retrieval of the Option IVC filter were performed safely and with high rates of clinical success.

What do family physicians know about interventional radiology? A survey of family physicians at a Large Canadian Annual Scientific Assembly.
To quantify the level of background knowledge among family physicians with regard to interventional radiology (IR) procedures, duties, and clinical responsibilities and to develop recommendations on how to further educate family physicians in IR. ⋯ The data quantify and demonstrate the knowledge gap that exists among family physicians in Canada regarding IR procedures, duties, and responsibilities. Family physicians strongly support future education and collaboration with interventional radiologists. Eight results-based recommendations are made to further educate family physicians about IR and promote increased collaboration.

Case ReportsPercutaneous repair of a nonunion pubic ramus fracture using a metallic stent scaffold and cement osteoplasty.
This report describes a case of repair of a nonunion pubic ramus fracture with intramedullary placement of a self-expanding nitinol stent across a fracture gap to provide a permeable scaffold for polymethylmethacrylate (PMMA) cement to track across the fracture gap and to restrict leakage into surrounding soft tissues. The patient presented with an 8-month history of pelvic pain and debility. His pain remains resolved after 14 months. Percutaneous repair of nonunion pubic rami fractures using a bridging metallic stent in combination with PMMA bone cement may be an effective treatment for these fractures.
