[Transient cerebral circulatory disorders in patients having sustained an ischemic stroke].

On the basis of analyzing the clinical picture of the disease in 81 patients with cerebral atherosclerosis the authors come to a conclusion that the transitory cerebral circulation disturbances exhibited by these patients after an ischemic stroke were usually due to a combined affection of the carotid and the vertebrobasilar arteries. In all these patients the ischemic focus was localized in the brain hemispheres within the basin of the median or posterior cerebral arteries and manifested in moderate focal symptoms. The disturbances usually arose some months or years after the stroke, and pointed, as a rule, to an insufficiency of the circulation in the brain trunk. The appearance of the transitory cerebral circulation disturbances after an ischemic stroke may be, probably, a consequence and manifested in moderate focal symptoms.

The disturbances usually arose some months or years after the stroke, and pointed, as a rule, to an insufficiency of the circulation in the brain trunk. The appearance of the transitory cerebral circulation disturbances after an ischemic stroke may be, probably, a consequence of a circulatory decompensation resulting from progressing atherosclerotic changes of the cerebral vessels, or may be due to a cerebrovascular insufficiency because of arterial pressure fluctuations or a cardiac disease.

[Prognostic value of different clinical symptoms in transient circulatory disorders in the vertebro-basilar system].

ON the basis of analyzing the clinical picture of the disease in 280 patients suffering from atherosclerosis with transitory disturbances of the circulation in the vertebrobasilar system the author comes to a conclusion that in patients with truncal strokes the clinical picture usually includes symptoms of preceding transitory ischemic episodes. In patients with an ischemic lesion in the basin of the posterior cerebral arteries, the lesion localization and the preceding transitory cerebral circulation disturbances are usually not in agreement: the episodes are characterized by a considerable polymorphism and not infrequently point to a circulatory insufficiency in the arteries of the truncal or the carotid systems. the character, frequency, duration, and number of episodes are of no decisive diagnostic importance as regards the possibility of an ischemic stroke development. One can only speak of a more favourable course of the disease in patients with attacks of systemic dizziness, and of a less favourable course in patients with attacks of unconsciousness and transitory global amnesia.

[Role of arterio-arterial embolisms in the pathogenesis of cerebral circulatory disorders].

The authors studied 52 patients with brain infarctions and transient disorders of cerebral circulation, which in the opinion of the authors developed as a result of arterio-arterial embolism. Besides, 16 post-mortem cases with arterio-arterial embolism were studied as well. On the basis of clinico-angiographical, clinico-laboratory and clinico-anatomical correlations, the authors come to the conclusion that this mechanism is frequently the main link in the pathogenesis of distrubed cerebral circulation. Embologenic materials in the development of brain infarctions are most often particles of parietal or obturating thrombi in the magistral cerebral vessels. In patients with transient disorders of cerebral circulation most likely embolism of the minor cerebral vessels by thrombocytic aggregates. The authors discuss the functional properties of thrombocytes in the pathogenesis of transient disorders of cerebral circulation and the feasibility of the use of antiaggregates for preventive purposes.

[Transient ischemic attacks and stroke].

The authors present some results of a study of 85 patients with brain strokes which were preceded by transient cerebral ischemic attacks. In most of the cases the brain stroke developed on the background of an ischemic cardiac diabetus, atheroscleorosis of the peripheral vessels, etc. It was established that in patients with atherosclerosis, the strokes developed at earlier periods after the first ischemic attack, than in the group of patients where atherosclerosis developed in combination with arterial hypertension. In disturbance of circulation in the basin of the carotid arteries, the strokes with preceding ischemic attacks developed not only more frequently, but earlier than those due to insufficiency of the circulation in the vertebro-basillar basin. It was also established that crude focal symptomatology appears as a rule in those cases when the stroke develops after the first ischemic attack. In frequent attacks which are repeated during several years, the appearing stroke is characterized by a more light focal symptomatology.
