The Author Spotlight video series is an opportunity for our authors to highlight their papers published in CVIR Endovascular, and to shed light on the hard work they do to improve patient outcomes, share knowledge on techniques and procedures, and redirect the focus on issues that need urgent attention.
Dr. Kevin Fung discussed the paper "Embolisation of an aneurysmal high-flow renal arteriovenous fistula in a paediatric patient: simultaneous arterial and venous approach"
The simultaneous deployment of coils through artery and veins serves as an alternative to more traditional flow control strategies such as using a proximal occlusion balloon that is more commonly described, especially in paediatric patients who have smaller femoral arteries
Dr. Francesco Giurazza spoke to us about how interventional radiology is characterised by the continuous introduction of new devices and technologies and thus, IRs need to not only be proficient in their clinical practice, but need to also understand the materials they work with. He and co-authors wrote this paper to explain their experience with the micro vascular plug Read the original paper: Embolization with MVP (Micro Vascular Plug®): experience on 104 patients in emergent and elective scenarios.
Dr. Mohammed Shamseldin (Helios Klinikum, Erfurt/DE) demonstrates how tools and tips from other areas can be applied in interventional radiology. In this video, he describes how cerebral stent retrievers may be used in removing different and rather unusual intra-arterial foreign objects in other parts of the body.

In the video, Dr. Haraguchi outlines two cases using the novel "fracking" technique he and co-authors Tsutomu Fujita, Yoshifumi Kashima, Masanaga Tsujimoto, Tsuyoshi Takeuchi, Yutaka Tadano, Daisuke Hachinohe, Umihiko Kaneko, Ken Kobayashi, Daitaro Kanno and Katsuhiko Sato published last year. In this technique, deep calcifications are cracked with hydraulic pressure via a balloon indeflator through an 18-gauge needle, which punctures calcifications to achieve greater acute luminal gain. Check out the original paper for a step-by-step guide for the technique including a video of the procedure!
We were thrilled to have Dr. Pereira talk to us about the paper "Superior hypogastric nerve block (SHNB) for pain control after uterine fibroid embolization (UFE): technique and troubleshooting", which he and co-authors Louis Maurice Morel-Ovalle, Mehdi Taghipour, Afsheen Sherwani, Roshni Parikh, Jerome Kao and Kirubahara Vaheesan wrote.
He discusses how this procedure offers female patients undergoing uterine fibroid embolisation pain control without opioids, and can even mean same-day discharge, which is a game changer for patients as well as doctors performing these procedures.
We caught up with Prof. Colin Cantwell, who discussed "Conventional angiography findings in hemodynamically unstable patients with acute abdominal hemorrhage and a negative CT bleeding study", the paper he and co-authors Amy O’Brien, Gerard Healy, Nicholas Rutledge, Aishan Patil, and Jeffrey McCann wrote on conventional angiography findings in hemodynamically unstable patients with acute abdominal hemorrhage with a preceding negative CTA. They analysed data to see if there is a connection between bleeding site and false CT findings.
Dr. Quencer has published several of the journal's most accessed papers, and we were delighted to have him talk to us about the paper "Adrenal vein sampling: technique and protocol, a systematic review" where he gave an overview of this procedure, including an assessment of different techniques and protocols in order to offer a guide to readers and to increase the procedure success rate overall.
Our most recent video features Prof. Kensaku Mori, who describes the "pigtail through snare" technique he and co-authors Chika Somagawa, Shun Kagaya, Masafumi Sakai, Satoshi Homma, and Takahito Nakajima developed to capture a catheter fragment. This technique is easier than the traditional 2-step technique, and is faster, thus reducing procedure time and radiation exposure.
Our latest video features Dr. Anne Gill, who discusses the paper she and co-author Giridhar M. Shivaram contributed to the CVIR Endovascular special section on paediatric IR. She outlines her experience and offers suggestions for medication, equipment, workup, and identifies barriers to successful management of acute and chronic systemic venous occlusions in children.
The next video in the series features Dr. Osman Ahmed, who presents the paper "Transsplenic portal vein recanalization and direct intrahepatic portosystemic shunt placement to optimize liver transplantation," written with co-authors Abhijit L. Salaskar, Steven Zangan, Anjana Pillai and Talia Baker.
He discussed a case where a patient with existing complications (incl. hepatic vein occlusion) needed to undergo a liver transplant, and how the team took a unique approach, utilising a trans-splenic PVR with DIPS placement. He emphasised the collaborative nature of this case and how this knowledge can be used to help other patients in the future.
Dr. Monica Matsumoto discusses the paper that she and co-authors Karan Nijhawan, Jeffrey A. Leef, Chelsea Dorsey & Osman Ahmed wrote, "Hybrid CT-angiography to facilitate lower extremity sharp venous recanalization: a novel approach to a common procedure."
In the video, she outlines how the case at hand highlights the potential for endovascular treatment (in this case, hybrid CT-Angiography, more commonly used in interventional oncology) of chronic venous occlusions.
Our next video in this series features Prof. Warren Clements, who discusses the paper he and co-authors Tim Joseph, Jim Koukounaras, Gerard S. Goh, Heather K. Moriarty, Joseph Mathew and Tuan D. Phan wrote about the SPLEEN-IN study: SPLEnic salvage and complications after splenic artery EmbolizatioN for blunt abdomINal trauma.
He gives insight into how splenic artery embolisation offers many blunt trauma patients an alternative to splenectomy, and explains why it is important to keep your spleen!
The series kicks off with Dr. Gregory Makris, who discusses the Letter to the Editor that he and Drs. Saqib Butt and Tarun Sabharwal published on unnecessary hysterectomies and the role of the interventional radiology community.
