[Screening for intracranial aneurysms].

This review states the reasons for considering screening for intracranial aneurysms in Denmark: if patients have two first-degree relatives with intracranial aneurysms, are 30-70 years old, do not have competing disorders, which could significantly shorten life expectancy, and subsequently in patients with autosomal dominant kidney disease and a family history of subarachnoid haemorrhage. MR angiography should be the imaging study of choice, unless contraindicated. Generally, the ethical consequences ought to be considered before carrying out screening.
