The results of a web-based survey designed to shed light on the practice of transarterial chemoembolization (TACE) in the UK have shown that there is a wide variation in practice with some centres using conventional TACE (with lipiodol and doxorubicin) and others using, newer drug-eluting beads.
SIR has unveiled a new brand for the society and its research organisation—SIR Foundation—reinforcing its commitment to patient-driven care and highlighting the power and potential of interventional radiology. The new logos for both organisations convey the limitless possibilities of image-guided therapies to solve the toughest medical problems. SIR’s new tagline, “The vision to heal” reflects the innovative, patient-driven care that board-certified interventional radiologists deliver through methods that result in less risk, less pain and shorter recovery time than traditional surgery.
Johns Hopkins researchers have developed a sugar-based molecular microcapsule that eliminates the toxicity of an anticancer agent developed a decade ago at Johns Hopkins, called 3-bromopyruvate, or 3BrPA, in studies of mice with implants of human pancreatic cancer tissue.
Recent advances in tissue engineering have led to an investigational off-the-shelf bioengineered blood vessel for implantation and provide vascular access for dialysis patients. The current standard of care for patients with end-stage renal disease requiring haemodialysis includes surgery to create an arteriovenous fistula, placement of a synthetic polytetrafluoroethylene (PTFE) graft, or a central venous catheter. Research shows that up to 50% of patients fail to adequately mature their fistulae after creation and are not suitable for dialysis within five months after surgical placement. Likewise, PTFE grafts are subject to a range of complications, including thrombosis, outflow vein stenosis, infection and high intervention rates to maintain blood flow. Catheters are known to have high rates of infection, inefficient dialysis and are associated with inducing central vein stenosis and occlusion.
CO2 angiography can decrease both morbidity and mortality for patients, in certain clinical scenarios. For those driven by economics, the cost of 100cc of CO2 is approximately three cents. Its use is limited only by one’s imagination. So why is it not more widely used?
Stentoplasty, or vertebral body stenting, represents the next step in the evolution of cement spinal augmentation where a stent is placed within the vertebral body followed by infusion of cement. Current available systems include the Osseofix system (Alphatec Spine) and the VBS system (Synthes). Uei Pua writes about the future directions of the procedure.
Covidien has announced the six-month results of the VeClose pivotal study, which demonstrated the safety and effectiveness of the VenaSeal closure system in patients with chronic venous insufficiency (CVI) having symptomatic reflux in the great saphenous vein. The results were presented at American College of Phlebology Annual Congress (ACP 2014; Phoenix, USA).
The Gore Viabahn Endoprosthesis has received CE mark approval to improve blood flow in symptomatic obstruction of peripheral veins, excluding the venae cavae and pulmonary veins.
The results of a new study presented at the annual meeting of the Radiological Society of North America (30 November–5 December, Chicago, USA) show that placement of internal iliac balloons is technically feasible, well-tolerated and leads to satisfactory maternal and foetal outcomes with minimal complications.
Medtronic has announced the latest results from two clinical studies analysing the performance of the Endurant AAA stent graft system. The Endurant system has been used to treat more than 165,000 patients worldwide since it was initially introduced in Europe in 2008, which according to a company press release, is more than any other device of its kind, being selected for nearly one of every two endovascular procedures to repair abdominal aortic aneurysms around the world.
ArtVentive Medical has received US Food and Drug Administration (FDA) clearance for the Endoluminal Occlusion System (EOS). Designed for use in the peripheral vasculature, the EOS offers immediate, complete and total occlusion in arterial and venous settings.
Suresh Vedantham, professor of Radiology, Interventional Radiology Section, Washington University School of Medicine in St Louis, USA, spoke to Interventional News on the latest from the paper “Quality improvement guidelines for the treatment of lower-extremity deep vein thrombosis with use of endovascular thrombus removal” hot on the heels of its online publication in the Journal of Vascular and Interventional Radiology (JVIR).
“No matter what their future orientation, interventional radiologists involved in interventional oncology need to have a basic training in what is called ‘general interventional radiology’ in order to be able to provide a uniform and standardised care,” José Ignacio Bilbao Jaureguízar, professor and head of the Department of Interventional Radiology, Clínica Universitaria de Navarra, Pamplona, Spain, told Interventional News.
In a new consensus statement, the Joint UK Societies claim that the negative results of SYMPLICITY HTN-3 should not be used as a “rationale for abandoning” renal denervation as a “novel therapeutic development” for resistant hypertension because they claim more clinical trials are needed to evaluate the safety and efficacy of the therapy.
Results of the DISRUPT PAD study show that Lithoplasty, a new balloon-based technology, demonstrates safety and efficacy in the treatment of superficial femoral artery and popliteal artery disease. Early results with the technology were presented at a late-breaking trial session at the Vascular Interventional Advances conference (VIVA, 4–7 November, Las Vegas, USA).
