Multidirectional extension and invasive spread are important features of giant pituitary adenomas. Operability cannot be established merely by determining the size of the most prominent part of the tumour. Detailed radiological evaluation with plain films, computed tomography, angiography, and air studies all contribute to evaluation of the precise anatomy(More)
Angiographic studies on 150 pituitary adenomas and 33 craniopharyngiomas presenting for surgical treatment are reviewed. Eleven incidental silent aneurysms (four arising from the intracavernous and four from the supraclinoid carotid artery, and three from the anterior cerebral artery complex) are shown. Intracavernous aneurysms were also present in two(More)
Magnetic stimulation of the nervous system is a new technique introduced in 1985 by Barker, Jalinous and Freeston. Using short pulses of a time-varying magnetic field it allows a noninvasive stimulation of the motor cortex and deeply placed peripheral nerves. The authors presented basic principles and applications of this method. Stimulation procedures were(More)
A consecutive series of 101 pituitary tumours treated in the 10 year period 1968-78 has been examined, giant lesions being excluded. There were 48 female cases and 53 male, women predominating in the ratio of three to two in the age group 40-50 years and men showing a slight predominance in the age group 50-60 years. Most cases presented with visual(More)
Peripheral nerve oxygen tensions were assessed in vivo by using microelectrodes to measure endoneurial oxygen tension in exposed sural nerve. In 11 diabetic patients with chronic sensorimotor neuropathy the mean endoneurial oxygen tension was 39.7 (SD 10.2) mm Hg. In all but one patient compared with none of four non-neuropathic subjects the mean nerve(More)
The authors analysed a series of 111 adult patients admitted to the Department of Neurosurgery, Medical University of Łódź directly after trauma with initial GCS of 3 points. 74% of them had intracranial haematoma, mainly subdural, and were treated surgically within the first 3 hours after trauma. 8 patients had no abnormalities on CT scans. 99 (89%)(More)
The authors describe the presentation, investigation and successful treatment of two giant serpentine aneurysms with Guglielmi detachable coils. Both aneurysms selectively involved the P2 segment of the posterior cerebral artery. The authors describe an endovascular approach to these challenging lesions as an alternative/adjunct to conventional surgery.
OBJECTIVE To evaluate the use of microvascular decompression (MVD) for the treatment of hemifacial spasm (HFS). METHODS Eighty three patients with HFS who underwent MVD via a suboccipital craniectomy are presented. RESULTS Seventy two out of seventy eight patients available for follow up remained free of any spasms at a mean follow up period of eight(More)
An experimental model of subarachnoid haemorrhage has been developed in the baboon to allow accurate measurements of the changes of ICP and cortical bloodflow, auto-regulatiion, reactivity changes and central conduction time extending over a period up to three months. Twelve hydrogen electrodes were implanted in pairs allowing CBF measurements in standard(More)
