Unruptured intracranial aneurysm screening

The idea of population screening of unruptured intracranial aneurysms is interesting because, despite recent advances in surgical and endovascular treatment, the mortality related to aneurysmal subarachnoid hemorrhage reaches 30%. Screening is justified whenever the morbidity and mortality of the treatment (markedly lower for unruptured compared to ruptured aneurysms) overcomes the inherent risk of harbouring a brain aneurysm. Although, at present, this balance does not seem to favour population-based screening, it is justified in certain sub-populations with an increased risk of rupture.

In a review, an analysis is made of the requirements for implementing a screening program, when would it be justified, what is to be expected from treatment (in terms of effectiveness, morbidity and costs), and what medical-legal issues are relevant and to determine the usefulness of the program. A study protocol is proposed aimed at examining the usefulness of population screening for intracranial aneurysms by magnetic resonance angiography 1).
