    Microplastics, nanoplastics, and PFAS in neurovascular interventions

    Neurovascular interventions rely on low-friction synthetic equipment, from multiple polymer-based and polymer-coated devices to plastic gloves. The paper discussed in this podcast highlights the discovery of quantifiable release of microplastics (MPs), nanoplastics (NPs), and per- and polyfluoroalkyl substances (PFAS) into the flush fluid during simulated neurovascular interventions. The study concludes that levels of PFAS, also called 'forever chemicals', released during thrombectomies were double those produced in aneurysm procedures. MP and NP levels did not differ between thrombectomy and aneurysm simulations. Although the exact impact on the human body is still understudied, the potential consequences remain concerning in all cases. JNIS Editor-in-Chief, Dr. Michael Chen, speaks with the corresponding author of the study, Dr. Sophia Hohenstatt (Department of Neuroradiology, University Hospital Heidelberg, Germany). Read the paper, "Workflow level release of microplastics, nanoplastics, and perfluoroalkyl and polyfluoroalkyl substances during simulated neurovascular interventions" (https://jnis.bmj.com/content/early/2026/09/15/jnis-2026-025917), freely available on the JNIS website.

    CSF-Venous Fistulas: a practical guide for interventionalists

    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.

    AI in neurointerventional surgery: evaluating LLMs decision-making capabilities in acute stroke triage

    Large language models (LLMs) are moving beyond simple data extraction to complex, guideline-based triage in emergency stroke care. In this episode, JNIS Editor-in-Chief, Dr. Michael Chen, speaks with Dr. Ayman Meddeb, a senior consultant and interventional neuroradiologist at Charité - Universitätsmedizin Berlin, Germany. They discuss his latest paper, "Evaluating accuracy and reasoning capabilities of large language models for acute ischemic stroke management" (https://jnis.bmj.com/content/early/2026/06/23/jnis-2026-025429).

    Super large bore catheters in stroke thrombectomy: a systematic review

    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 stroke: systematic review" (https://jnis.bmj.com/content/early/2026/03/27/jnis-2026-025001).  They discuss published data on super large bore catheters (SLACs; inner diameter ≥0.080 inch), highlighting key metrics including first-pass effect, overall recanalization rates, and navigability through tortuous intracranial vasculature.

    Combined delivery catheters vs. traditional aspiration in stroke thrombectomy

    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 talk about their multi-centre paper, "Faster reperfusion with combined delivery catheter systems and aspiration first stroke thrombectomy: a multicenter analysis" (https://jnis.bmj.com/content/early/2026/06/19/jnis-2025-024700). The authors discuss data comparing combined delivery catheter systems against standard aspiration setups, highlighting significantly faster times from groin puncture to clot contact and an impressive 67% first-pass effect. They also share key clinical insights on overcoming severe arterial tortuosity. Please subscribe to the JNIS podcast on your favourite platform to get the latest podcast every month.

    Endovascular shunting for normal pressure hydrocephalus: safety trial insights with Professor Adel Malek

    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.

    Reperfusion grade and outcomes in the ESCAPE-MeVO Trial

    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.

    Reducing opioid use after aneurysmal subarachnoid hemorrhage: the role of MMA infusion

    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. Link to the discussed paper: "Middle meningeal artery infusion for headaches after aneurysmal subarachnoid hemorrhage: a pilot study".
