[Screening for aneurysms in risk groups: meaningful?].

There is a controversy discussion on screening for aneurysms in risk groups. True guidelines do not exist so far. It seems that screening for familial aneurysms is not advisable today. But adult dominant polycystic kidney disease (ADPKD) patients with a familial history of SAH should be screened because of a high prevalence rate of 25% for intracranial aneurysms in this population. Screening should be performed every 2 to 3 years by MRI angiography in this special risk group.
