[Results of surgical treatment of aneurysms of the anterior communicating artery].

The authors present the results of surgical treatment of 48 aneurysms situated on the anterior communicating artery operated upon by the classic and microsurgical methods. The latter method has made it possible to raise the proportion of very good and good results from 23% in the classic method to 70%, and to reduce the postoperative mortality in groups I and II of condition severity from 13.6% to 4%. Independently of the method used Korsakoff's syndrome was observed in 17% of cases. The high value of Yasargil's surgical approach is stressed.

[Chronic bilateral subdural hematoma].

The authors report 31 patients treated surgically for chronic bilateral subdural haematomas stressing the diagnostic difficulties in such cases and discussing the value of radiological investigations and surgical methods, especially multipoint trepanation.

[Differential diagnosis between third-ventricle neoplasms and tumors of the posterior fossa based on clinical manifestations and results of contrast radiograms of the brain].

Differential diagnosis in the material was based on the neurological and radiological findings made in 45 patients with third-ventricle tumours and 133 with subtentorial tumours. No clinical syndrome has been found which could help in reliable diagnosis concerning either of these locations of the tumour. Of decisive significance for the correct localization of tumours was ventriculography which established the diagnosis in 42 cases of third-ventricle tumours and 103 cases of subtentorial tumours. The most difficult problem was recognition of the relation of the subtentorial tumours to the brain stem since this relation could not be indicated unequivocally neither by clinical findings nor by radiological examination. This required surgical revision of the posterior fossa in most cases with suspected brain stem tumours.

[Aneurysm of pericallosal artery].

The authors describe 3 cases of saccular aneurysms of the pericallosal artery. They accounted for 3.36% of all intracranial aneurysms in the material of the authors. Difficulties in management of pericallosal artery aneurysms are discussed. All patients with aneurysms in this area were operated upon from an approach through the interhemispheric fissure and the results were good.

[Comparison of results of polygraphic sleep studies and cerebrospinal fluid pressure records in patients following removal of supratentorial expanding lesions].

In 4 patients operated upon for supratentorial brain tumors the authors carried out on the 3rd day after the operation polygraphic recording of nocturnal sleep with simultaneous measurements of cerebrospinal fluid pressure in the ventricular system by the method of Lundberg. A comparison of polygraphic records of nocturnal sleep with parallel measurements of intraventricular pressure demonstrated that all REM phases were associated with a rise in intraventricular pressure, while during phases 3 and 4 of sleep (NREM) the intraventricular pressure was always lower. In the remaining sleep phases 1,2 NREM and during episodes of nocturnal awakening no unequivocal consistencies were found.

[Cerebrospinal fluid pressure measurements in the ventricular system during and after surgery in patients with supratentorial brain tumors].

In the light of CSFP measurements by Lundberg's method in 46 patients the authors showed the role of hyperventilation in lowering of intracranial pressure. A considerable efficacy of dexamethasone was demonstrated as well, the use of this drug permitted to achieve stabilization of CSFP during and after the operation. The investigations showed a considerable effectiveness of such drugs as mannitol and furosemide in lowering of CSFP. Pancuronium was found to be superior to suxamethonium for administration during induction of anaesthesia because the former caused no CSFP rise. In polygraphic investigations of nocturnal sleep with parallel recording of CSFP a rise of CSFP was demonstrated during REM phase of sleep.

[Results of polygraphic nocturnal sleep recording in patients with supratentorial brain tumors prior to and following surgery].

The purpose of the study was to establish the influence exerted by a supratentorial brain tumour on the EEG correlates of sleep, and to compare the results before and after operation. Five patients were studied (aged 38 to 59 years) who were treated surgically for supratentorial expanding lesions: two cases of meningioma (in left parietal area), two cases of glioma (right parietal area and occipital area) and one case of intracerebral haematoma. The control group comprised 5 patients operated upon for lesions of the peripheral nerves of extremities. In the patients with supratentorial brain tumours and after their removal the following sleep parameters were unchanged: total sleep duration, number of awakening during sleep, latency time of the first REM phase and stage 3 NREM (deep and superficial sleep). The amount of REM sleep increased after tumour removal. REM-sleep density was selectively and permanently disturbed. In presence of tumour REM-sleep density was found in traces only, after tumour removal it increased but showed a permanent high-grade deficit in relation to controls.
