Intra-arterial nimodipine treatment of subarachnoid hemorrhage patients

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.

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).

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.

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.

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.
