🌀 Why do some aneurysms occlude quickly after flow diversion despite persistent high-speed flow? This JNIS study suggests that aneurysm occlusion is not driven by flow reduction alone. In fast-occluding aneurysms, progressive fibrin accumulation across the flow diverter disrupted the inflow jet, increased neck coverage, and substantially reduced intra-aneurysmal velocity. A fascinating look at the biology and hemodynamics behind successful flow diversion. 🔗 bit.ly/47SQp6m #JNIS #FlowDiversion #Aneurysm #Neurointervention

Can we predict how a flow diverter will actually deploy before we deploy it? 🧠💻 In a real-world simulation-guided workflow, Ankyras closely predicted PED: 🎯 Deployed length: MAE 1.24 mm 📍 Proximal landing zone: MAE 1.34 mm 📈 Strong correlations: r=0.91 and 0.94 Virtual planning may be moving closer to real-world deployment. 🔗 bit.ly/4hXsoRS #JNIS #FlowDiversion #BrainAneurysm #Neurointervention

Can superbore aspiration push first-pass reperfusion further? 🧠 The prospective multicenter MARRS trial evaluated the corrugated Millipede aspiration system in 180 patients with LVO stroke. 🎯 88.9% mTICI ≥2b within ≤3 passes without rescue ⚡ 75% FPE in M1 occlusions treated with Millipede88* 📈 82.2% final mTICI ≥2c overall 🛡️ 2.3% sICH | 0 perforations *Per-protocol M1 subgroup. 🔓 Open Access: bit.ly/3UwpjPg #JNIS #Stroke #Thrombectomy #Neurointervention #Aspiration

When CSF disappears into the venous system, how do you find the fistula? 💧🧠 A comprehensive JNIS review of CSF–venous fistulas takes us from pathophysiology to localization and treatment: 🔎 Decubitus DSM & CTM 🩸 Percutaneous therapies 🧭 Transvenous embolization 🧠 Surgery & post-treatment care A practical roadmap for a rapidly evolving field. 📖 Read the full review: bit.ly/4fV6QCP #JNIS #CSFLeak #Neurointervention #SIH

Why do some aneurysms remain patent after flow diversion? 🧠 In 185 aneurysms, branch involvement was the strongest predictor of incomplete occlusion. But not all branches behaved alike—accounting for collateral circulation improved prediction scores. 🔗 bit.ly/3TKoAtm #JNIS #FlowDiversion #Aneurysm #Neurointervention

What causes acute periorbital swelling after EVT? This case series highlights an uncommon but important complication following EVT: the spectrum of orbital infarction syndrome (OrbIS) and secondary orbital inflammation (SOIN). Recognizing the differences in timing, clinical presentation, and visual outcomes may help guide early diagnosis, ophthalmology consultation, and multidisciplinary management. 📖 Read more at bit.ly/3RGib1E

🎤 The final lecture of SNIS 2026 featured @JMoccoMD’s Medicolegal Perspective, offering valuable insights into navigating risk and responsibility in neurointerventional practice. Key takeaways included the importance of documenting clinical decision-making, engaging patients through a true consent process, and recognizing communication as a modifiable factor in reducing medicolegal risk. A powerful reminder that transparency, trust, and the physician-patient relationship remain central to excellent care. 🧠

🧊 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. Read more here: bit.ly/4wfNb78

🎧 A new episode of the JNIS podcast has been released: 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) to discuss his high-impact paper, "Safety of endovascular shunting for normal pressure hydrocephalus from a prospective, multicenter, single-arm study”. bit.ly/44aBNxm Listen & subscribe to the JNIS Podcast on your favorite platform: ▶️ Apple: apple.co/4gf7Fbu ▶️ Spotify: bit.ly/4vOlt11 ▶️ Web: bit.ly/4eHNWQv

Could targeting the middle meningeal artery help reduce headache and opioid use after aneurysmal subarachnoid hemorrhage? In this JNIS pilot study, MMA infusion of lidocaine ± dexamethasone during aneurysm embolization was associated with reduced pain burden, lower opioid use, and no complications in patients with low-grade aSAH. @PeterKa80460001 @utmbhealth @UTMBNeurosurg @DrHongTao Read more: bit.ly/3OZgScN
