Chris Andersen has spent a career treating subarachnoid haemorrhage, and he opens this episode by admitting we might have wasted a fortune treating vasospasm without evidence to show for it. Host Oli Flower and Chris Andersen, co-conveners of ISAH 2026, dig into why SAH care hasn't seen the revolution ischaemic stroke has, why delayed cerebral ischaemia (DCI) is the field's great unsolved problem, and why fewer than 10% of SAH trials have ever asked patients what actually matters to them.
Chris Andersen is a neurocritical care specialist and co-convener of ISAH 2026, the International Conference on Subarachnoid Haemorrhage, running 17–20 November in Sydney.
