Supplementation of conventional radiographic techniques by computer tomography in cases of subarachnoid haemorrhage (SAH).

124 patients with a spontaneous intracranial haemorrhage were examined. On almost 100% of the cases, the diagnosis could be established computer-tomographically if the study was performed within 5 days following the haemorrhage. As a result of the bleeding pattern it was possible to determine the exact location in 54 (75%) of 71 aneurysms. The clinical course of the patient can be more closely followed without additional risk. Thus with the use of CT, the development of cerebral infarction resulting from arterial vasospasm (6 cases) or of hydrocephalus as a result of CSF resorption disturbances can be easily and quickly determined.
