title: [Angiographic diagnosis of subarachnoid hemorrhage--a study of 160 patients].
abstract: Among 1916 cerebral angiographies carried out in the years 1973 to 1977, the examination was made in 160 patients (= 8.4 per cent) after verified subarachnoid haemorrhages. In 107 cases (= 67 per cent) a morphological substrate was secured angiographically. Arterial cerebral aneurisms and arteriovenous angiomas were the most frequent causes of a haemorrhage with an occurrence of 32.5 and 16.3 per cent, respectively. Further causes were: degenerative diseases of the cerebral vessels in 11.9 per cent, intracerebral haematomas in 3.1 per cent, haemorrhages in tumours in 1.9 per cent and stenosis of the aortic isthmus in 1.3 per cent of the cases. In 33 per cent of the cases a morphological substrate could not be ascertained angiographically. Including the authors' own experiences, diagnostic criteria are derived which to a large extent co-determine the decision with regard to an operation including the respective technical procedure.
