Introduction

There are three main classes of non-traumatic SAH. These are:

  • Aneurismal SAH
  • Non-aneurismal SAH
  • Vascular rarities such as arterio-venous malformations (AVMs), dissections, tumours and vasculitides

This session looks at aneurismal and non-aneurismal SAH.

Vascular rarities will be covered in other sessions in the Learning Curriculum.
