There is no evidence that accumulation in the brain of the element gadolinium speeds cognitive decline, according to a new study presented at the annual meeting of the Radiological Society of North America (RSNA).
Paolo Zamboni, Ferrara, Italy, the proponent of the chronic cerebrospinal venous insufficiency (CCSVI) theory, and his colleagues have reported that the randomised, double-blinded, sham controlled Brave Dreams trial has not demonstrated a benefit for venous angioplasty in the treatment of patients with multiple sclerosis (MS).
Intact Vascular has announced that positive single centre twenty-four month results from its TOBA (Tack optimised balloon angioplasty) clinical study were presented at VEITHsymposium 2017 by Christian Wissgott, assistant director, Westküstenklinikum Heide in Heide, Germany.
Philips has announced the results of a comprehensive, independent, two-year study demonstrating the clinical workflow benefits of its next generation image-guided therapy platform, Azurion.
The Society of Interventional Radiology (SIR), in coordination with Member of the US House of Representatives (Rep.) from Utah’s 4th district, Mia Love, hosted a panel discussion on the important role of interventional radiologists on trauma teams responding to mass casualty incidents.
The new European Directive laying down basic safety standards for protection against the dangers arising from ionising radiation exposure will come into effect on 6 February 2018. The most relevant change for interventionists in the occupational exposure section is the new annual limit for the lens of the eyes (20 mSv/year, instead of 150 mSv/year), write Eliseo Vano (Madrid, Spain) and Gabriel Bartal (Kfar Saba, Israel).
The health implications of prolonged low dose radiation exposure are frequently a topic of discussion amongst vascular interventionalists, who are performing a growing number of fluoroscopically guided procedures of increasing complexity. Anecdotal evidence points to an alarming pattern of premature, atypical malignancies in high volume operators. However, in the absence of large, prospective registries relating radiation dose to long-term health effects, a causal link with prolonged exposure cannot be established.
“There is little experience with the use of cryoablation in children. Our aim was to evaluate the feasibility of cryoablation for benign soft tissue lesions in children,” said Alex M Barnacle, Great Ormond Street Hospital For Children, London, UK, speaking at the British Society of Interventional Radiology meeting (BSIR; 1–3 November, Birmingham, UK).
Mercator MedSystems has announced completion of enrolment in the company’s LIMBO-ATX (Lower-limb adventitial infusion of dexamethasone via Bullfrog to reduce occurrence of restenosis after atherectomy-based revascularisation) clinical trial. The primary six-month endpoint data is expected to be available in the second quarter of 2018.
The European Commission, under the EU Merger Regulation, has approved the acquisition of Bard by BD, subject to conditions. Both US-based companies supply medical devices including catheters, stents, surgical instruments, devices for biopsies, and patient monitoring systems.
The primary importance of collecting data from registries would be to establish outcome data to prove the value of the interventional oncologic therapies to healthcare administrations and governments; ie. to establish interventional oncology’s value in healthcare. Further, it could help gather data to confirm that interventional oncology treatments of cancer impact patients’ lives and the quality of their survival.
The US Food and Drug Administration has cleared the first seven tesla (7T) magnetic resonance imaging (MRI) device, more than doubling the static magnetic field strength available for use in the USA. The Magnetom Terra (from Siemens) is the first 7T MRI system cleared for clinical use in the USA.
Vivasure Medical has announced the successful enrolment of the first patient in the Frontier IV clinical study, a non-randomised multicentre international trial, designed to expand the indications of its proprietary PerQseal large arteriotomy closure technology. The patient was enrolled by Peter Crean (Blackrock Clinic, Dublin, Ireland).
Six-month results from a prospective, randomised, non-inferiority study presented at the Cardiovascular and Interventional Radiological Society of Europe (CIRSE; 16–20 September, Copenhagen, Denmark) reveal that prostatic artery embolization is safe and effective in the treatment of benign prostatic hyperplasia (BPH) and that it results in symptomatic improvement for patients based on achieving a decrease in prostate volume.
Gerard Goh, Radiology, The Alfred Hospital, Melbourne, Australia, reported results from a comparative study of inferior vena cava (IVC) filters at CIRSE 2017 that examined the effectiveness, safety and complication rates of the Celect, Celect Platinum and ALN vena cava filters.
