Diagnosing and managing cerebrospinal fluid-venous fistulas (CSFs) requires navigating complex venous anatomy and nuanced imaging techniques. In this episode, JNIS Editor-in-Chief, Dr. Michael Chen, speaks with associate editor Dr. Emanuele Orru (Lahey Hospital and Medical Center, Burlington, Massachusetts, USA) about establishing a systematic, multidisciplinary framework to identify and treat these low-pressure CSF leaks. Dr. Emanuele Orru is the corresponding author of the paper: Cerebrospinal Fluid–Venous Fistulas: Pathophysiology, Diagnosis, and Management (https://jnis.bmj.com/content/early/2026/07/16/jnis-2026-025062), freely available on the JNIS website.

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, "Safety of endovascular shunting for normal pressure hydrocephalus from a prospective, multicenter, single-arm study”. They discuss the results of this 66-patient, prospective trial, exploring how the novel eShunt system accesses the cerebellopontine angle cistern to drain CSF and relieve pressure.  Please subscribe to the JNIS podcast on your favourite platform to get the latest podcast every month.

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 following medium vessel occlusion thrombectomy in the Endovascular Treatment to Improve Outcomes for Medium Vessel Occlusion trial".  Please subscribe to the JNIS podcast on your favourite platform to get the latest podcast every month.

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 (MMA) during aneurysm embolisation.  They explore the safety of this targeted approach, its impact on Visual Analog Scale (VAS) pain scores, and its potential as an opioid-sparing strategy in the neuro-ICU.

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 cadaveric models, and potential implications for minimally invasive neurosurgical practice.

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 new survey has been carried out to assess the severity and prevalence of negative psychological effects on physicians who have experienced these complications. Dr. Ansaar Rai¹ joins JNIS Editor-in-Chief Dr. Michael Chen to discuss the original research piece, "Unseen wounds: a multinational investigation of neurointerventionalists on the psychological toll of complications".  (1) Interventional Neuroradiology, West Virginia University Rockefeller Neuroscience Institute, Morgantown, West Virginia, USA Please subscribe to the JNIS podcast on your favourite platform to get the latest podcast every month.

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 both from the University of California San Francisco, USA. They discuss the current evidence base, highlight the strengths and limitations of non-invasive imaging techniques such as MRI, MRA, CT, and CTA, and outline a practical algorithm for streamlining diagnosis.    Please subscribe to the JNIS podcast on your favourite platform to get the latest podcast every month.

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.   Editor-in-Chief of JNIS, Dr. Felipe C.

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 association between the ADI and the treatment of ruptured intracranial aneurysms compared with unruptured intracranial aneurysms across multiple centres. Editor-in-Chief of JNIS, Dr. Felipe C. Albuquerque, interviews Dr. Alexandra Paul¹, author of the paper: Multicenter study of association between socioeconomic status and treatment of ruptured cerebral aneurysms compared to unruptured cerebral aneurysms: insights from 4,517 patients using the area deprivation index   1.

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.
