Introduction
There are three main classes of non-traumatic SAH. These are:
- Aneurysmal SAH
- Non-aneurysmal SAH
- Vascular rarities such as arterio-venous malformations (AVMs), dissections, tumours and vasculitides
This session looks at aneurysmal and non-aneurysmal SAH.
Vascular rarities will be covered in other sessions.
