The place of digital intravenous angiography in cerebral infarcts

The authors describe their technique of intravenous digital subtraction angiography (IVDSA) and discuss the results in cerebral infarcts. IVDSA is a good first stage examination for the recognition of stenosis or occlusion of cervical vessels to the brain, as it is an only marginally invasive and easy technique. It is, however, good neither for the study of focal cervical not of intracranial areas.
