Venous Access: National Guideline and Registry Development (VANGUARD): Advancing Patient-Centered Venous Access Care Through the Development of a National Coordinated Registry Network.

There are over 8 million central venous access devices inserted each year, many in patients with chronic conditions who rely on central access for life-preserving therapies. Central venous access device-related complications can be life-threatening and add tens of billions of dollars to health care costs, while their incidence is most likely grossly mis- or underreported by medical institutions. In this communication, we review the challenges that impair retention, exchange, and analysis of data necessary for a meaningful understanding of critical events and outcomes in this clinical domain.

Advancing the Real-World Evidence for Medical Devices through Coordinated Registry Networks.

Objectives: Generating and using real-world evidence (RWE) is a pragmatic solution for evaluating health technologies. RWE is recognized by regulators, health technology assessors, clinicians, and manufacturers as a valid source of information to support their decision-making. Well-designed registries can provide RWE and become more powerful when linked with electronic health records and administrative databases in coordinated registry networks (CRNs).

Research Priorities for Percutaneous Arteriovenous Fistula Creation in Patients with End-Stage Renal Disease: Proceedings and Recommendations from a Multidisciplinary Research Consensus Panel.

Recently developed endovascular techniques to create percutaneous arteriovenous fistulas are an alternative to surgical arteriovenous fistula creation, although there is currently a lack of high-level evidence regarding their creation, maturation, utilization, and long-term function. Recognizing this, the Society of Interventional Radiology Foundation sponsored a Research Consensus Panel and Summit for the prioritization of a research agenda to identify and address the gaps in current knowledge.

Evidence-Based Strategies and Recommendations for Preservation of Central Venous Access in Children.

Children with chronic illness often require prolonged or repeated venous access. They remain at high risk for venous catheter-related complications (high-risk patients), which largely derive from elective decisions during catheter insertion and continuing care. These complications result in progressive loss of the venous capital (patent and compliant venous pathways) necessary for delivery of life-preserving therapies.

Combined Surgical and Transhepatic Rendezvous Procedure for Relieving Anastomotic Biliary Obstruction in Children with Liver Transplants.

Four children (3 boys and 1 girl, age 1.4-9.4 y) presented 2-70 months after liver transplantation (mean 26 months) with high-grade narrowing at the surgical anastomosis that could not be crossed at percutaneous transhepatic cholangiography.

Host conditioning and rejection monitoring in hepatocyte transplantation in humans.

Background & Aims: Hepatocyte transplantation partially corrects genetic disorders and has been associated anecdotally with reversal of acute liver failure. Monitoring for graft function and rejection has been difficult, and has contributed to limited graft survival. Here we aimed to use preparative liver-directed radiation therapy, and continuous monitoring for possible rejection in an attempt to overcome these limitations.

Advancing medical device innovation through collaboration and coordination of structured data capture pilots: Report from the Medical Device Epidemiology Network (MDEpiNet) Specific, Measurable, Achievable, Results-Oriented, Time Bound (SMART) Think Tank.

The Medical Device Epidemiology Network (MDEpiNet) is a public private partnership (PPP) that provides a platform for collaboration on medical device evaluation and depth of expertise for supporting pilots to capture, exchange and use device information for improving device safety and protecting public health. The MDEpiNet SMART Think Tank, held in February, 2013, sought to engage expert stakeholders who were committed to improving the capture of device data, including Unique Device Identification (UDI), in key electronic health information. Prior to the Think Tank there was limited collaboration among stakeholders beyond a few single health care organizations engaged in electronic capture and exchange of device data.

Long-term central venous access in pediatric patients at high risk: conventional versus antibiotic-impregnated catheters.

Purpose: To study selective use of antibiotic-impregnated catheters in children at increased risk of venous catheter-related infections (CRIs).

Materials And Methods: From December 2008 to June 2009, 428 peripherally inserted central catheters (PICCs) were placed by the interventional radiology service of a large metropolitan children's hospital. This retrospective study analyzed demographic and outcome data for the 125 patients in this group at high risk for venous CRI.

Radiologically placed tunneled hemodialysis catheters: a single pediatric institutional experience of 120 patients.

Purpose: To report the outcome of tunneled dialysis catheter insertion in 120 patients.

Materials And Methods: A retrospective review of the interventional radiology database and electronic medical records of 120 patients who had tunneled dialysis catheters inserted from April 1997 to July 2010 was performed with institutional review board approval. There were 61 female patients and 59 male patients, with a mean age of 13.

Barriers to the successful treatment of liver disease by hepatocyte transplantation.

Management of patients with hepatic failure and liver-based metabolic disorders is complex and expensive. Hepatic failure results in impaired coagulation, altered consciousness and cerebral function, a heightened risk of multiple organ system failure, and sepsis [1]. Such manifold problems are only treatable today and for the foreseeable future by transplantation.

Botulinum toxin A injection of salivary glands in children with drooling and chronic aspiration.

Purpose: To review outcomes of ultrasound (US)-guided percutaneous submandibular gland injection of botulinum toxin A (BTX-A) in the treatment of drooling and chronic aspiration.

Materials And Methods: A 3-year retrospective review was performed of 220 US-guided salivary gland injections in 36 patients. There were 21 male patients and 15 female patients with an age range of 1.

Cavoatrial junction and central venous anatomy: implications for central venous access tip position.

Purpose: To quantify the anatomic relationships of the cavoatrial junction and propose a system for describing central venous access device tip location on the basis of structures visible on chest radiographs.

Materials And Methods: The authors performed a retrospective study of 100 consecutive computed tomographic (CT) studies from a predominantly pediatric population consisting of 52 male and 48 female patients aged 12-28 years (mean age, 16 years). With use of multiplanar and scout images, relevant mediastinal structures were marked, vertebral levels were noted, and measurements were made electronically.

Reactive arthritis of the temporomandibular joints and cervical spine in a child.

Background: Temporomandibular joint (TMJ) arthritis is frequently seen in children with chronic arthritis. It has rarely been described in a non-infectious acute setting. We report a case of reactive arthritis isolated to the TMJs and cervical spine.
