[Neuroradiologic aspects of aneurysm-induced subarachnoid hemorrhage and its complications].

The distribution of aneurysms in 129 patients with subarachnoidal haemorrhage (SAH) (ACA 42%, MCA 27%, ICA 21%, vertebral and basilar artery 10%) differs from the result of large statistics, where aneurysms of the ICA represent the most frequent group. The difference is considered as a consequence of the small statistical group. No differences were found with respect to complications from SAH (angiospasm 24%, infarction 14%, hydrocephalus 18%, second haemorrhage 23%, mortality 20%). The validity of CT and angiography in search for SAH and aneurysm and temporal aspects, correlated with the examination, are discussed.
