[Angio-ultrasonography--a method of examining the extracranial arteries].

The authors describe a method of investigations of the extracranial cerebral arteries--angioultrasonography based on the Doppler effect. The study was done with a Polish apparatus designed and produced by the Experimental Laboratory of the Institute of Basic Technical Problems, Polish Academy of Sciences. The study confirmed the usefulness of this method in the diagnosis of arterial diseases involving the extracranial arteries supplying the brain. A high agreement was demonstrated between the results of angioultrasonography and classical angiography. Owing to the use of a grey scale it was possible to localize accurately the site of stenosis or occlusion of the studied artery.

[The ascending frontal artery system: morphological and radiological analysis].

After an analysis of anatomical preparations of cerebral hemispheres, postmortem angiograms and normal intravital angiograms the morphological pattern of the branches of the middle cerebral artery forming the system of the ascending frontal artery and the most frequent varieties of the origin, course and shape of these branches were evaluated.

Cerebral Angiography↗

[Role of computerized tomography in the diagnosis of arteriovenous anomalies of the brain].

The authors describe typical and atypical patterns of cerebral arteriovenous anomalies demonstrated by means of computerized tomography performed in 12 patients in whom these anomalies were found during subsequent operations. The authors compare the advantages and disadvantages of computerized tomography and angiography in the diagnosis of these anomalies.

Cerebral Angiography↗

[Assessment of regional cerebral blood flow (rCBF) and vascular changes in angiographic studies in cases of cerebral ischemia].

In 22 patients the regional cerebral blood flow (rCBF) was measured after intra-arterial injection of xenon 133Xe. In all patients cerebral angiography was performed after that and in 4 patients aortic arch angiography was done as well. In 2 cases of subclavian artery stenosis with normal state of the branches of the internal carotid artery the rCBF was not decreased. On the other hand, a significant decrease of rCBF was found in cases of transient cerebral ischaemic episodes with angiographically demonstrated bilateral stenosis of the afferent arteries and coexistence of stenosis of the afrerent arteries supplying the brain and intracranial arteries. On the basis of an analysis of rCBF angiograms the authors suggest the conclusion that a joint evaluation of the clinical manifestations, results of rCBF measurements and angiograms increases the accuracy of assessment of the condition of the cerebral circulation in patients qualified for patency-restoring operations.

[Angiographic assessment of collateral circulation pathways in the stenosis and occlusion of the extracranial cerebral arteries].

Visualization in angiographic investigations of the common carotid artery of certain collateral circulation routes can sometimes facilitate evaluation of the site of occlusion and its extent. Collateral circulation via the arterial network of the nape of the neck indicates stenosis or occlusion of the subclavian artery. Collateral circulation through the muscular branches of the occipital artery to the vertebral and basal arteries suggests lesions in the vertebral artery. Collateral circulation via the anterior communicating artery suggests stenosis or occlusion of the contralateral internal carotid artery. Visualization in the angiograms of the common carotid artery of numerous channels of collateral circulation indicates presence of disseminated changes in the extracranial brain-supplying arteries.

Arterial Occlusive Diseases↗

[The value of computer tomography in the diagnosis of encephalomalacic foci].

The authors report a comparative analysis of the results of angiographic investigations and computer tomography in patients with clinical manifestations of stroke. Attention is called to the accuracy of the information obtained in computer tomography with regard to the extent of focal encephalomalacia and stage of evolution. Signs are described making possible differentiation between vasogenic lesions and other pathological processes of identical or similar features in computer tomography.

[Computed X-ray tomography in cases of metastatic brain tumors].

The authors describe the role of computerized tomography in the diagnosis of metastases to the brain and orbit, and analyse computer tomography findings in different types of metastases. Because the metastases are visualized better after administration of contrast medium the importance of this tomography done before and after administration of contrast medium is discussed.
