[Dominance of cerebral hemispheres and visual space-hand localization]. / Dominacja pólkuli mózgu a wzrokowa lokalizacja przestrzenna reczna.

The visual space-hand localization from each eye and by each hand was examined by means of a localizer. Two kinds of examination were performed: one checked the initial, the other the postexercise localization. The dominance of the cerebral hemispheres was determined by psychological tests. No dependence of the behaviour of the visual hand localization on the domination of a given hemisphere was shown.

[Effect of classic exclusion of middle cerebral artery aneurysm on late structural and functional changes in the vicinity of the operation site]. / Wplyw klasycznego wylaczenia tetniaka tetnicy srodkowej mózgu na pózne strukturalne i czynnosciowe zmiany w otoczeniu miejsca operacji.

On the basis of neurological, psychological and computed tomographic examinations of the head late consequences are presented of classical exclusion of middle cerebral artery aneurysm. It was demonstrated that compression of the brain with a spatula and the extent of shifting apart of the walls of the lateral fissure of the brain during the operation may lead to ischaemic changes in the temporal lobe near the lateral fissure. These changes may cause impairment of mental efficiency late after the operation. It was shown also that during the operations for aneurysms of the middle cerebral artery at the site of its division the approach by forcing apart the fissure over the site of division would be less damaging than the approach along the trunk of the artery.

[Effect of classical exclusion of aneurysm of the internal carotid artery on late structural and functional changes at the site of the operation]. / Wplyw klasycznego wylaczenia tetniaka tetnicy szyjnej wewnetrznej na pózne, strukturalne i czynnosciowe zmiany w otoczeniu miejsca operacji.

The effect of the classical exclusion of internal carotid aneurysm with access by frontotemporal craniotomy on late therapeutic result and on the development of ischaemic changes in the area of access was analysed. It was shown that with this method of surgical treatment the ischaemic lesion developed most frequently in the temporal lobe pole, and may lead to persistent impairment of mental ability and symptoms of characteropathy later on. It was demonstrated that the occlusion of bridging veins reaching the sphenoparietal sinus and ligation of the neck of the aneurysm increased the risk of ischaemic lesions development at the site of spatula pressure during the operation.

[Analysis of the effects of various methods of classical exclusion of anterior cerebral artery aneurysms on late structural and functional changes in relation to the various approaches]. / Analiza wplywu róznych metod klasycznego wylaczania tetniaka ukladu tetnic przednich mózgu na pózne, strukturalne I czynnosciowe zmiany z róznymi sposobami dojscia.

The effects were analysed of various techniques of classical exclusion of aneurysms in the anterior cerebral artery system on the late therapeutic result and on the development of ischaemic lesions in the area of approach to the aneurysm. The approaches used were: interhemispheric, fronto-temporal and fronto-temporo-sphenoidal, and the aneurysms were excluded with a ligature or metal clip. The best method of approach was chosen after analysis of late results of neurological, psychological and CT studies. It was demonstrated that pressure of a spatula during the operation may produce permanent ischaemic changes at the site of the pressure which may lead to persistence of psychic disturbances late after the operation. It was shown also that the most favourable classic technique of operation in cases of aneurysms in this portion is the fronto-temporo-sphenoidal approach with use of a metal clip.
