Follow-up MS MRI report “stable”
But could MRI disease activity have been missed? — In this study 20% of F/U MRI reported “stable” using routine comparison had at least one missed lesion. These missed lesions were associated with future disease activity.

🎧 New JNIS Podcast Episode

Does achieving near-complete reperfusion in medium vessel occlusions translate to better clinical outcomes?

In this episode, JNIS Editor-in-Chief Dr. Michael Chen speaks with Prof. Johanna Ospel about a post-hoc analysis of the ESCAPE-MeVO trial, exploring the relationship between reperfusion grade, infarct volume, and 90-day functional outcomes (https://t.co/ikwglF0bsU).

⚡ Can impedance sensing provide real-time insight into clot composition during mechanical thrombectomy?

In this first-in-human JNIS study, an impedance-sensing guidewire demonstrated high accuracy in distinguishing red blood cell–rich from platelet-rich clot components during mechanical thrombectomy.

Impedance sensing also identified clot boundaries in situ, with no device-related intracranial vessel perforations or dissections reported.

What is the current role of middle meningeal artery embolization (MMAE) in chronic subdural hematoma management?

📖 These updated recommendations review the evidence supporting MMAE as an adjunct to surgical drainage, considerations for standalone treatment in select populations, and key technical and safety principles for contemporary practice.

💡 What is the current evidence on coil-only middle meningeal artery embolization (MMAE) for chronic subdural hematoma (cSDH)?

In this JNIS scoping review, authors analyzed 9 studies including 367 patients and 459 embolization procedures evaluating coil-only MMAE for cSDH.

Recurrence rates ranged from 0–17.6%, reintervention rates from 0–15.4%, and complication rates from 0–5%. Techniques varied from proximal MMA trunk occlusion to more distal branch-level coiling, with potential advantages of coil-only MMAE in anatomically challenging cases.

🧠 Veins are not arteries. Direct angioscopic visualization of the dural venous sinuses revealed why arterial-derived devices often struggle in venous interventions: parallel channel navigation, stent deformation, constrained expansion, and aspiration catheter occlusion. These findings underscore the need for venous-specific technologies. Read more here: https://t.co/TXezD7nqkC

🧊 This in vitro study demonstrates that catheter insulation, flow rate, and proximal blood flow control are key determinants of intra-arterial brain cooling efficiency. An insulated co-axial catheter combined with balloon guide catheter inflation achieved the greatest predicted brain temperature reduction.

🧵 Can endovascular embolization serve as a standalone treatment for select intracranial meningiomas?

In this multicenter study, authors evaluated 41 intracranial meningiomas treated with standalone embolization across four centers. Tumors demonstrated progressive regression over time, with median volume reductions of 28.6% at 1 month, 57.1% at 6 months, and 81.7% at 12 months.

An early devascularization index predicted greater subsequent tumor shrinkage. Complications occurred in 4 of 41 lesions, with one resulting in a mild clinical decline. No patient required subsequent surgery or radiotherapy.

🧐 Which dAVFs are less likely to be cured with embolization alone?

Among 415 patients with high-grade DAVFs, middle meningeal artery feeders are associated higher odds of successful treatment, while pial arterial supply, venous congestion, and multiple fistulas were linked to lower odds of success.

#SNIS2026 Day 3 Lecture Spotlight: For this year's Grant Hieshima Luminary Lecture, Dr. @JoshuaAHirsch presented a historical perspective on neurointervention, illustrating how innovation, scientific evidence, and healthcare policy have shaped the specialty. He reviewed CPT coding, Medicare, RVUs, the RUC, reimbursement reform, and vertebral augmentation as an example of how evidence ultimately drives policy and patient access.

#SNIS2026 Day 3 Lecture Spotlight: Dr. David Fiorella shared encouraging early results on the use of the TRUFILL™ n-BCA Liquid Embolic System for patients with refractory migraine. Although the trial is still ongoing, the benefits of embolization appear to be durable, with improvements maintained out to 6 months. Importantly, he emphasized that while these single-arm results are promising, a randomized controlled trial will be essential to confirm efficacy.

🧠 SNIS 2026 Day 1 Lecture Spotlight: @chriskellnerMD explores the exciting potential of vagus nerve stimulation (VNS) for stroke recovery.

⚡ Prior studies have shown that VNS can improve upper extremity function after stroke, with emerging evidence suggesting meaningful gains are possible even in patients with chronic stroke. The early data are certainly promising—but what comes next? Dr. Kellner discusses where the field is headed and the future of this innovative approach to neurorehabilitation.
