ISAH

"Practice-changing things that maybe aren't guideline ready — but get us ready for the next version." That's @NerissaKoMD on why ISAH matters. We'll take it. Sydney. November. subarachnoid.org/register #ISAH2026 #aSAH @NeurosurgUCSF

This aSAH PechaKucha is 12+ years old. The emergency framework holds. The 2012 guidelines don't. TXA and coiling-vs-clipping have both moved on. Sharing it as a warm-up — ISAH 2026 is running a PK competition. Best entries present in Sydney. ▶️ vimeo.com/60622349 #ISAH26

Founding editor of the Journal of NeuroInterventional Surgery. Past SNIS president. 450+ publications. @JoshuaAHirsch at #ISAH2026 - the global SAH forum. 📍 Sydney | Nov 17–20 subarachnoid.org/register

Jose Suarez on what he would NOT do in a DCI trial: choose one medication with one mechanism of action. "We'll just be replicating the same failures." It's a short answer. The implications aren't. ISAH 2026 | Sydney | 17–20 Nov subarachnoid.org #ISAH26

525+ peer-reviewed papers. 2 dozen trials. Still asking whether we're treating the right aneurysms. J Mocco joins #ISAH2026 📍 Sydney | Nov 17–20 events.humanitix.com/isah-2026

SAH guidelines have an RCT purity problem. Nerissa Ko (UCSF): for rare, variable diseases, holding out for trials that may never come isn't rigour - it's stasis. 📍 ISAH 2026 | Nov, Sydney 🔗 subarachnoid.org/register #ISAH2026 #aSAH

2 decades building the evidence base for who's actually at risk from their aneurysm - & who isn't. Sepideh Amin-Hanjani (Chair, AHA Stroke Council; VP, AANS) is supporting #ISAH2026 in Sydney this November. The only global meeting dedicated to SAH. 🎟️ subarachnoid.org/register

Decades of DCI trials. Still on nimodipine. Jose Suarez (Johns Hopkins) breaks down why: flawed models, skipped phase 2, single-pathway thinking & makes the case for combination therapy. ISAH 2026, Sydney. 🔗 subarachnoid.org/register #ISAH26 #SubarachnoidHemorrhage #DCI

More intervention ≠ better outcome. We still haven't solved that. Stephan Mayer joins #ISAH2026 📍 Sydney | Nov 17–20 events.humanitix.com/isah-2026

Nerissa Ko helped write the SAH guidelines. We asked her why nobody follows them. 3 reasons: → Disease is too heterogeneous → Evidence base too thin → We haven't agreed on the right outcomes yet That's the conversation. #ISAH2026 Sydney, November. 🔗 subarachnoid.org

Same aneurysm. Different clinicians. Different decisions. Why? Peter Mitchell joins #ISAH2026 📍 Sydney | Nov 17–20 events.humanitix.com/isah-2026

Hyperventilation in SAH: drops ICP AND cerebral blood flow. In a brain already in trouble. Prophylactic hyperventilation when ICP isn't confirmed? Guessing. Possibly harmfully. Claude says "ish-shame-ic". It would be a shame. #NeuroResus #SAH #FOAMed 🎧 neuroresus.com/2026/04/30/sah…

Claude explained the CONSCIOUS trials. Confidently. Completely wrong. CONSCIOUS is about clazosentan. The negative result changed the field. Corrected on air. Told to examine its "beady, glowing eyes." #NeuroResus #SAH #FOAMed 🎧 neuroresus.com/2026/04/30/sah…

She co-wrote the 2023 AHA/ASA SAH guidelines. She'll tell you why that wasn't enough. Nerissa Ko joins #ISAH2026 — Sydney, Nov 17–20 🔗 events.humanitix.com/isah-2026

Time is brain." Also true: dead patients don't scan well. Stabilise first. Scan second. Not controversial — just occasionally forgotten when everyone's rushing to CT. #NeuroResus #SAH #FOAMed 🎧 neuroresus.com/2026/04/30/sah…

Guidelines simplify. Reality doesn't. Jose Suarez at #ISAH2026 Time to look at where recommendations help — and where they don't. 📍 Sydney | Nov 17–20 events.humanitix.com/isah-2026

"You want enough pressure to perfuse a brain with buggered autoregulation - but not so much that you're blowing the aneurysm apart." I did not expect an AI to nail the SAH BP dilemma that cleanly. #NeuroResus #ISAH2026 #FOAMed 🎧 neuroresus.com/2026/04/30/sah…

Important meeting. @IntSAH is one of the few forums actually taking on the uncertainty in aneurysm and SAH care rather than pretending it’s solved. Serious people, real debates, and the kind of cross-specialty discussion we don’t get enough of. Sydney, Nov 2026. Worth your time👇

"Less than 8, intubate." Sure. But what if she's postictal and about to wake up? What if intubation tanks the BP? What if the pressure spike causes a rebleed? GCS 8 is a data point. Not a decision. #NeuroResus #SAH #FOAMed 🎧 neuroresus.com/2026/04/30/sah…

I made a podcast with two AIs. One confidently misrepresented a landmark trial. On SAH. In real time. That's not a bug. That's the point. NeuroResus Ep 1 is live - GCS 8, buggered autoregulation, and ED chaos. 🎧 neuroresus.com/2026/04/30/sah… #NeuroResus #SAH #FOAMed @IntSAH
