Interventional News’ top 10 most read articles of June 2022


Among the most popular pieces from last month are reports on papers delivered at the Society of Interventional Radiology (SIR) 2022 Annual Meeting (11–16 June, Boston, USA), two stories of innovations in pain management, and a write-up of a call to action regarding limiting radiology staff lead exposure.


1) Report recommends action within radiology departments to reduce lead dust exposure

‘Surface lead contamination on personal lead radiologic protective apparel’ is a recent report published by Kieran Murphy et al (Toronto Western Hospital, Toronto, Canada). The subject of the report is free lead dust on lead aprons: the study involved testing aprons at a Toronto university hospital, which yielded the finding that 60% of aprons and thyroid shields have free surface lead. 


2) SIR 2022: Treating placenta accreta spectrum with multivessel pelvic embolization

‘Multivessel pelvic embolization during caesarean hysterectomy for placenta accreta spectrum: A single-centre experience and comparison to internal iliac artery balloon occlusion’ was presented at SIR.


3) TriSalus presents preclinical data on proprietary infusion technology at SIR 2022

The data are the result of evaluations of the company’s immunotherapy platform, which integrates an investigational class C toll-like receptor 9 (TLR9) agonist, SD-101, and the proprietary Pressure-Enabled Drug Delivery (PEDD) method of administration to overcome critical treatment barriers.


4) Yasuaki Arai

“I do not want interventional radiology to be a treatment for the rich, nor for those who live in the wealthiest countries.” Yasuaki Arai was, until recently, executive advisor to the president at Japan’s National Cancer Center in Tokyo, where he is currently a member of the interventional radiology centre.


5) Authors receive accolade of ‘Abstract of the Year’ at SIR 2022

Four of the abstracts submitted were declared ‘Abstract of the Year’ by Society of Interventional Radiology (SIR) scientific chairs. The prizes were conferred during the final plenary session of the meeting, and, according to SIR, reward the ‘best scientific work’ in terms of ‘overall quality, timeliness and content’.


6) Early study suggests a new, injectable gel may greatly reduce chronic low back pain

An experimental formulation of a hydrogel injected into spinal discs proved safe and effective in substantially relieving chronic low back pain caused by degenerative disc disease (DDD), according to new research.


7) Boston Scientific announces agreement to purchase majority stake of M.I.Tech from Synergy Innovation

M.I.Tech is the creator of the HANAROSTENT technology, a family of conformable, non-vascular, self-expanding metal stents, which have been distributed by Boston Scientific in Japan since 2015.


8) Shimadzu Medical Systems announces release of new angiography system at SIR 2022

Shimadzu Medical Systems USA introduced the new Trinias system, which uses artificial intelligence deep learning to improve the visibility of medical devices while using lower X-ray doses than previous models, at SIR 2022.


9) New study cites a possible breakthrough treatment in pain management

Damaged nerves can be regenerated with the application of a frozen needle using an advanced imaging technique called interventional cryoneurolysis, which is performed by an interventional radiologist and can offer hope to patients in persistent pain following a traumatic injury, according to an SIR press release.


10) First patient enrolled in SELUTION SLR IDE BTK study

The first patient has been enrolled in the US Food and Drug Administration (FDA) investigational device exemption (IDE) below-the-knee (BTK) SELUTION4BTK clinical trial involving SELUTION SLR, MedAlliance’s sirolimus-eluting balloon.
