[Andrew Koo, MD @AndrewBKoo]

End of an era. Two year enfolded neuroendovascular fellowship with @MatoukCharles and Ryan Hebert, MD.

Thank you for the trust and mentorship only time could have built. And thank you, patients and families, for your trust in us. Onwards to chief residency at #YaleNeurosurgery

A new technique developed at YSM improves molecular profiling of #brain cells by simultaneously comparing #protein and RNA levels across individual #cell types in living tissues, offering a clearer picture of what causes cells to falter in brain diseases: https://t.co/WleLc2tXnD

Excited to share our new work in Neurology: Does intensive BP lowering differ in deep vs lobar ICH? https://t.co/IFeVQKqFSF
Signals of heterogeneity across 3 ICH trials suggest location-specific effects.
IPD meta-analyses and targeted trials are needed.

Thank you for the opportunity to present at SBMT2026 on carotid revascularization techniques and our latest work on eShunt feasibility in IIH.🧠Exciting conversations in neurotechnology ahead! @MatoukCharles @YNeurosurgery

[JNIS @JNIS_BMJ]

🧠 In a prospective multicenter study of 66 patients with NPH, transvenous eShunt placement showed no device-related SAEs at 90 days and significant improvements in gait, cognition, and urinary symptoms.

Amazing work @DadaRenedo, Congratulations !!

[Daniela Renedo @DadaRenedo]

Honored to receive the Mordecai Y.T. Globus New Investigator Award at #ISC2026.

Grateful for the mentorship, collaboration, and support that make this work possible—and excited to keep pushing translational stroke research forward.

[Dr. Lee Schwamm @Braindoc_MGH]

@PoojaKhatriMD honored at #ISC26 @AHAScience with the Feinberg Award for her decades of contributions to improving stroke science and outcomes. Great and humble leader and newly appointed Chair of Neurology @YaleMed. A distinguished career recognized by her peers!

[Stroke AHA/ASA @StrokeAHA_ASA]

In a study based on the UK Biobank, SLAMF1 (a receptor involved in modulating innate and adaptive immune responses) was associated with increased risk of SAH. #stroke https://t.co/fhRfnREGXc

Thanks @NN_publishing for featuring our work! @musc_star @EmoryNeurosurg

[JNIS @JNIS_BMJ]

We all know that ⏰ is 🧠. Do different time intervals have different impacts on outcomes? This large retrospective study demonstrates that procedure duration predicts outcomes more than prehospital delay for EVTs! This emphasizes the importance of skilled interventionalists performing thrombectomies! @musc_star @alex_spiotta @AliAlawiehmdphd https://t.co/dJF1VY73pD

Single-cell RNA-seq of #stroke clots reveals cause-specific signatures, suggesting new biomarkers. #AHAJournals @DadaRenedo @jn_acosta @sujijantaratMD @AndrewBKoo @CyprienRivier @SanticlocMD @jpantonios @GuidoFalconeMD @LaurenHSansing @MatoukCharles https://t.co/bxQXfmfIdt

New study out: 📊

In neurointerventional surgery, women remain only 1 in 10 authors.
First authorship ↑ (10%→17%), but senior/last authorship barely moved (6%→9%).
Progress is happening, but equity in leadership is still far away.

Thank you, @GreenJournal , for highlighting our study on ischemic stroke rates and outcomes after cardiac interventions in the US 🫀🧠

Grateful to the @YaleMed Neurology, NSGY, CT Surgery teams for their collaboration #Stroke #neurotwitter #TeamScience

[Neurology Journal @GreenJournal]

This study identifies contemporary perioperative ischemic stroke rates and outcomes following cardiac interventions in the United States https://t.co/movu9NFHjV

An amazing event filled with incredible science and innovation in the neuroendovascular community! Thank you for the invitation to discuss our workup and management of pulsatile tinnitus.

[New York Symposium- Innovation in Neurosciences @NYNeuroendovasc]

Dr. Charles Matouk and Dr. Andrew Koo present "Silencing the Noise: Neuroendovascular Approaches to Tinnitus Management," a groundbreaking step toward treating tinnitus at its source. #NYSIN25
