BACKGROUND: In @entity439 of cerebral vessels it is essential to correctly identify the @entity439 that has caused the @entity548 , since it must be operated first. On the basis of our own material, we have evaluated the usefulness of various clinical signs and examinations in diagnosing which of several @entity439 was the cause of an @entity932 . MATERIAL/METHODS: The material consisted of 163 @entity1 with a total of 391 @entity439 . Diagnosis was based on panangiography and neurological examinations in all cases and CT in the majority. RESULTS: All the diagnostic examinations in question (neurological, angiography, CT and intraoperative evaluation) enabled a correct diagnosis in 72.6% of cases. In CT scanning, diagnostic value diminishes with time. @entity1779 is the most persistent sign. The highest rupture index involved @entity439 localized on the anterior communicating artery, while those on the internal carotid artery ranked second. Four @entity1 in whom intraoperative evaluation showed that the order in which the @entity439 were treated surgically was erroneous died as the result of rebleeding that occurred prior to planned follow-up surgery. CONCLUSIONS: It is vitally important for outcome to determine which of several @entity439 has @entity397 , since errors in the sequencing of surgical repair significantly increase mortality due to rebleeding preceding the next stage of surgery. When diagnosing the source of a @entity548 one should take into account neurological findings, angiography, EEG, CT, MRI, and the location of the @entity439 .
