Five new posters. You'll need a bigger wall.
In September we put out four posters. Here are five more, and this time they're doing a bit more work.
All five are A4, free to print, and carry a QR code that goes straight to registration. Below is the thinking behind each one, with a download under every poster, or you can grab all five in one go.
Thunderclap
Every aSAH story starts the same way: the worst headache of someone's life, at full strength within a minute. Lightning over the Opera House and the Harbour Bridge, because the meeting is in Sydney and because nothing else in medicine announces itself quite like this.
The tagline does the maths. The bleed takes a second. We've given it four days :)
Arachnoid
Arachnoid comes from the Greek for spider's web, after the cobweb-like membrane the blood ends up beneath. Sydney is home to the funnel-web, so the venue more or less chose itself lol.
The vertical text is the meeting's name in Japanese. English hides the spider in Greek. Japanese puts it in plain sight: subarachnoid haemorrhage is くも膜下出血, kumomakka shukketsu, literally bleeding beneath the spider membrane. A nod to our Japanese colleagues, whose work runs through a good chunk of the vasospasm literature and we're lucky to have Shinichi Yoshimura speaking at ISAH2026.
Seven millimetres
With apologies to John Carpenter & Kurt Russell. Seven millimetres is the line much of the unruptured aneurysm literature has been drawn around since ISUIA, and it's baked into risk scores like PHASES. The awkward bit: plenty of the aneurysms we treat after rupture are smaller than that.
Whether small means safe, and whether our risk models are as precise as they look, is exactly the kind of argument this meeting exists for. Look closely at the dots on the i's.
Bifurcation
Aneurysms like a fork in the road. Most saccular aneurysms sit at arterial branch points, where flow hits the apex hardest. Here the fork splits CON into CONTROVERSY and CONSENSUS, with a red sac sitting right at the junction.
That's the meeting in one picture. Some sessions will end in agreement, some won't, and both outcomes shape the next trial.
The calendar
For people who just want the dates. Workshops on Tuesday 17 November, the main meeting Wednesday to Friday, Monday and the weekend struck out. It also previews three questions on the program: why have so many aSAH trials failed, should we treat tonight or wait until morning, and when is treatment futile?
Pin this one next to the roster.
Where to put them
The ICU tearoom. The neurosurgery reg office. The angio suite. The ED doctors' room. Radiology reporting. Anywhere with a noticeboard and a population of people with strong opinions about blood pressure targets.
Every poster has a QR code straight to registration, so it can do the recruiting while you do the shift. If you put one up, take a photo and tag ISAH 2026 on LinkedIn. We'd like to see where they end up!
ISAH 2026 runs 17–20 November at the Sheraton Grand Sydney Hyde Park. Four days on aneurysmal subarachnoid haemorrhage and nothing else. Register here.
