Evaluating device performance, safety, and procedural efficacy remains essential as mechanical thrombectomy technology for large vessel occlusion (LVO) rapidly evolves. In this episode, JNIS Editor-in-Chief, Dr. Michael Chen, talks with Dr. Marc Ribo, an interventional neurologist at Vall d'Hebron University Hospital in Barcelona, Spain. They discuss his systematic review paper, "Super large bore catheters in the treatment of strok...

Optimising mechanical thrombectomy speed and efficiency remains a primary focus in acute ischemic stroke management. In this episode, JNIS Editor, Dr. Michael Chen, talks with Dr. Keiko Fukuda, a neurointerventional fellow at UCLA and practising neurointerventionalist in Monterey, California, and Dr. Victor Szeder, Professor of Radiology, Neurology, and Neurosurgery and Director of the Neurointerventional Fellowship at UCLA.

They t...

Evaluating the 90-day safety and technical feasibility of a percutaneous transvenous approach represents a critical milestone for routing cerebrospinal fluid (CSF) – the clear liquid that cushions the brain and spine – directly into the venous system.

In this episode, JNIS Editor, Dr. Michael Chen, talks with corresponding author Professor Adel Malek (Tufts Medical Center, Boston) (1) to discuss his high-impact paper, "...

Achieving near-complete reperfusion in medium vessel occlusions (MeVO) is linked to smaller final infarct volumes.  However, this did not translate into a statistically significant shift in 90-day functional independence.  

In this episode,  JNIS Editor-in-Chief, Dr. Michael Chen, and Professor Johanna Ospel (1) discuss the post-hoc analysis of the ESCAPE-MeVO trial, titled "Reperfusion grade and clinical outcome fol...

Headache affects up to 90% of patients following aneurysmal subarachnoid hemorrhage (aSAH), often requiring high-dose opioids that can complicate neurological monitoring. 

In this episode, JNIS Editor-in-Chief, Dr. Michael Chen, is joined by Professor Peter Kan¹ to discuss a prospective pilot study investigating a novel dural therapy: the infusion of lidocaine (with or without dexamethasone) via the middle meningeal artery (MM...

Can aqueductal stenosis be treated through a minimally invasive endovascular approach without transgressing brain parenchyma?

In this episode, JNIS Editor-in-Chief, Dr. Michael Chen, speaks with neuro-interventional radiologist Dr. Michal Obrzut¹ about a neurointerventional approach to the management of obstructive hydrocephalus secondary to aqueductal stenosis.

The author describes the underlying concept, technical feasibility in ...

Medical professionals can oftentimes fall under the category of "second victims", as they experience burnout and moral injury from the impacts of their work. Over the course of a neurointerventionalist's medical career, serious complications in procedures are sadly inevitable. These can be difficult to process, and there are not always the systems in place to provide the support needed, either inside or outside of the hospital. A n...

Dr Donald Heck (1) and Dr Peter Kan (2) join JNIS Editor-in-Chief Dr. Michael Chen to discuss the commentary “Middle meningeal artery embolization in the routine care of chronic subdural hematoma?” by D.V. Heck et al.

They highlight key debates around efficacy, safety, and workflow integration as embolization moves closer to becoming a routine therapeutic option.

Pulsatile tinnitus — the perception of a rhythmic sound in sync with the heartbeat — can be a key indicator of underlying vascular or structural pathology. In this episode, JNIS new Editor-in-Chief Dr. Michael Chen speaks with Dr. Madhavi Duvvuri and Dr. Matthew Robert Amans, authors of Non-invasive imaging modalities for diagnosing pulsatile tinnitus: a comprehensive review and recommended imaging algorithm. They are b...

In the SCENT trial, researchers investigated the effects of the Surpass flow diverter system for treating wide-necked aneurysms. Five-year results of this trial have recently been published in JNIS, presenting the safety and effectiveness outcomes of treatment with the Surpass Streamline flow diverter system. The study analyses the rates of aneurysm occlusion and adverse events.

High risk factors for stroke such as smoking and blood pressure are not equally represented throughout the patient population. These are just two of the socioeconomic influences on cerebrovascular disease. One way to view this association is through the lens of the Area Deprivation Index (ADI), a measure of neighbourhood-level deprivation, and this was the approach of the study discussed in this episode. The study evaluated the ass...

The "River" stent is a novel stent designed specifically to account for the anatomical and procedural requirements of venous sinus stenosis. A multicentre study of the device's safety and efficacy is underway, comprising 39 subjects across 5 US centres. The 1-year results have been recently published in JNIS. Editor-in-Chief of JNIS, Dr. Felipe C. Albuquerque, interviews Dr. Athos Patsalides¹, author of the paper: The River study: ...

Observations from practice and data analysis have shown that the duration of mechanical thrombectomy procedures are a strong predictor of outcome even with successful procedures. A large multicenter study was conducted which gives insight into choices between catheter types, and strategic decisions to be made during prolonged procedures.

Dr Felipe C. Albuquerque, Editor-in-Chief of JNIS, interviews Dr. Ali Alawieh¹ and Dr. Alejandr...

The use of assistive devices when treating unruptured aneurysms is widespread in neurointerventional practice. But there is no standard for how long patients should receive dual anti-platelet therapy after the procedure, to protect them from thrombotic complications. Durations can range from one month to one year. This episode looks at a review of patient data across 12 locations to understand the effect of therapy duration on risk...

There has been a large increase in the number of non-invasive neurovascular studies performed in the last decade, particularly CT angiograms and MR angiograms. What has this meant for catheter-based angiography? This episode looks at an analysis done on a large claims database in the USA, to observe trends in imaging modalities, as well as the distinctions in use by neurosurgeons and radiologists.

Dr Felipe C. Albuquerque, Editor-i...

Although many U.S. neurointerventionalists report at least one stressful malpractice claim over their career, the majority conclude without any court proceedings or direct repercussions in their practice. In this podcast, we look at the prevalence and causes of malpractice claims and complaints filed with state medical boards against neurointerventionalists, and some of the risk factors in an increasingly busier field.

Single-stent assisted coiling techniques such as ‘L-stenting’ are an alternative to intrasaccular devices for wide-neck bifurcation aneurysms. In this episode, Aliya Siddiqui¹ and Dr. Reade De Leacy² join JNIS editor-in-chief Dr. Felipe Albuquerque to discuss the background and findings of their recent study, regarding the efficacy and safety of the 'L-stenting' technique.

Patients with good motor function outcomes after aneurysmal subarachnoid hemorrhage treatment may still be left with neuropsychiatric effects. They can suffer from such difficult conditions as cognitive dysfunction, depression and sexual dysfunction. Not all of these patients will volunteer their symptoms unprompted on follow-up. This outcome type has had limited study, and became an interest of today's guest, Dr. Jose Danilo Bengz...

Alis Dicpinigaitis (1) and Dr. Fawaz Al-Mufti (2) join JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque, to discuss the study, "Mapping geographic disparities in treatment and clinical outcomes of high-grade aneurysmal subarachnoid hemorrhage in the United States". They explain the findings of their study, covering the predictive impact of factors including age, insurance status, race, and hospital ownership.
