[A comparison of cerebral angiography and computer tomography in patients with strokes (author's transl].

The computer tomographic findings in 230 patients with a clinical diagnosis of strokes or cerebral infarcts are described. In 185 of these patients cerebral angiography was performed in addition. The size and localisation of infarcts as shown on the computer tomogram were compared with the changes found in the carotid angiogram and were also related to the localisation of occlusion or stenosis of the corresponding extra- and intracranial vessels. In the presence of a normal carotid angiogram, CT may show infarcts of varying localisation and size; with stenoses or occlusion of the extracranial portion of the internal carotid artery, the infarcts tend to be smaller and that, in the presence of occulsions of the intracranial cerebral vessels, infarcts tend to be more extensive and to correspond to the territory supplied by the occluded vessels. Twenty-eight intracerebral haematomas and nine cerebral tumours were found amongst patients who presented as cerebral infarcts, with little evidence of massive cerebral bleeding; these are discussed separately.
