Endovascular coiling vs neurosurgical clipping

Death or dependence · people with subarachnoid haemorrhage from a ruptured intracranial aneurysm

Endovascular coiling probably leads to lower poor outcome: death or dependence in daily activities (12 months) compared with neurosurgical clipping (moderate certainty).
