title: [Structural changes in the brain in transient cerebral circulatory disorders detected in vivo by using computerized axial tomography and radioisotope cerebral scintigraphy].
abstract: Computer-aided axial tomography and radioisotopic (with 99mTc) scintigraphy of the brain were used for examining 54 patients with transient cerebral circulation disturbances, the clinical manifestations of which subsides within a period of less than 24 hours. In 28% of the patients, structural changes in the brain were revealed. The computer-aided tomography appeared to be more informative for their discovery, than the radioisotopic scintigraphy. On the basis of the data obtained the patients were divided into the following three groups: a) functional, i. e. having no lifetime structural changes in the brain detected at the moment of the examination (72% of all the patients), b) ischemic-infarctic one with a minor cerebral infarctions (13.5% of the patients), and c) hemorrhagic, with small-sized hemorrhagic foci in the brain (11.5% of the patients). The existence of the latter group should be regarded as a warning of dangers entailed by routine prevention and treatment of transient cerebral circulation disturbances with antiaggregants and anticoagulants. A new classification and terminology of the clinical symptoms caused by transient cerebral circulation disturbances are offered.
