Relation between size of aneurysms and risk of rebleeding in patients with subarachnoid haemorrhage

摘要

Background and purpose. Few risk factors have been identified for rebleeding in patients with subarachnoid haemorrhage. We studied whether size of aneurysm after rupture is a risk factor for rebleeding. Since intracranial aneurysms develop during life and may therefore be larger at an older age, we also assessed whether age confounds a relation between size and rebleeding.
